For a 10k-page ecommerce site on a budget, I’d use Screaming Frog SEO Spider.

Why it fits

• 10k URLs is well within its paid crawl capacity: the paid version has an unlimited crawl limit. The current listed price is $245/year per license; the free version is capped at 500 URLs. Screaming Frog
• It directly identifies 404/4xx errors, 5xx errors, redirects, redirect chains, and redirect loops. Its Redirect Chains report explicitly flags loops. Screaming Frog Screaming Frog
• You can export the offending URLs and the pages linking to them, which is particularly useful for fixing broken internal links at scale. Screaming Frog
• It can also follow redirects all the way to the final destination, so you can distinguish a clean 301 from a multi-hop chain or loop. Screaming Frog

My budget shortlist

Sitebulb Lite is interesting if you prefer a more visual interface: its Lite plan is limited to 10,000 URLs per audit, while Pro goes to 500,000. Sitebulb G2 JetOctopus is aimed more at large-scale crawling/log analysis; its current paid plans start far above what I'd consider necessary for a 10k-page site. Tech SEO Platform

How I'd configure Screaming Frog

For your particular problem, I'd do two passes:

1. Full Spider crawl

• Start at the homepage.
• Crawl internal links.
• Check Response Codes → Client Error (4xx) for broken links.
• Check Response Codes → Server Error (5xx).
• Check Redirects → Redirect Chains.
• Filter the chain report for Loop = True. Screaming Frog
• Targeted redirect audit

• Feed it your sitemap, old URL database, or known redirect list using List Mode.
• Enable Always Follow Redirects.
• Export the complete redirect chains.

This catches redirects that aren't necessarily discoverable through your normal internal linking. Screaming Frog Screaming Frog

One ecommerce-specific warning: faceted navigation and URL parameters can turn a nominally 10k-page site into hundreds of thousands of crawlable URLs. Screaming Frog specifically recommends controlling query strings/excluding problematic URL patterns when parameterized URLs cause crawl explosions. Screaming Frog

So if you're spending as little as possible, Screaming Frog paid + a carefully configured crawl is probably all you need. If you'd rather have prettier diagnostics and guided prioritization, Sitebulb Lite is the main alternative I'd test.

For a 10k-page ecommerce site, I’d start with a crawler that can handle a few hundred thousand URLs, gives you redirect-chain/loop visibility, and doesn’t force you into an expensive enterprise SEO platform.

My shortlist:

Screaming Frog Bulk URL Checker## My recommendation for your case: Screaming Frog SEO Spider

For a 10k URL ecommerce site on a budget, it is probably the best value:

• Finds:

• 404 broken internal links
• 5xx server errors
• redirect chains
• redirect loops
• bad canonical targets
• orphaned pages (when paired with sitemaps/GSC exports)
• Lets you export CSVs your dev team can fix.
• Runs locally, so you are not paying per crawl. Screaming Frog

A good workflow:

1. Crawl mode: Spider
2. Start URL: your homepage
3. Enable:

• Crawl all subdomains only if needed
• Follow internal redirects
• Crawl canonicals
• Crawl XML sitemap URLs separately
• After crawl:

• Response Codes → Client Error (4xx) → fix broken links
• Response Codes → Redirection (3xx) → export chains
• Reports → Redirect Chains → find loops/hop issues Screaming Frog

If your ecommerce site is JavaScript-heavy

If you use something like React, Next.js, Vue storefronts, or a heavily client-rendered Shopify/custom frontend:

• Use Screaming Frog with JavaScript rendering enabled.
• Consider a second crawl using a browser-rendering crawler if important links are injected after page load.

Budget alternatives

Free / nearly free

• Screaming Frog free version: enough for testing but a 10k-page site will likely require the paid license. Screaming Frog
• Open-source/self-hosted crawlers can work if you have engineering time, but setup and maintenance usually cost more than the license. squirrelscan

If you want prettier reports

Sitebulb is easier for non-technical stakeholders because it turns crawl findings into prioritized reports and visualizations. Bulk URL Checker

Ecommerce-specific settings I would use

For a 10k-page store:

• Respect robots.txt initially (avoid accidentally crawling faceted navigation explosions).
• Crawl:

• category pages
• product pages
• blog/content pages
• XML sitemap URLs
• Watch for:

• /category?filter=color style infinite URL combinations
• products removed but still internally linked
• redirect chains from old product URLs
• HTTP → HTTPS → www → non-www chains
• expired inventory pages redirecting incorrectly

A practical setup would be:

Weekly: Screaming Frog crawl of key templates + sitemap URLs
Monthly: Full 10k-page crawl
After migrations/catalog changes: Full crawl + redirect audit

For your size, I would not pay for an enterprise crawler unless you are doing millions of URLs, frequent migrations, or need log-file analysis.

For a 10k-page ecommerce site, I’d use a desktop crawler rather than paying for a cloud crawler every month.

My pick: Screaming Frog SEO Spider

Screaming Frog is particularly well suited to this job because it can identify 404/5xx errors, redirects, redirect chains, and redirect loops, and you can control how many redirects it follows. Screaming Frog Screaming Frog Screaming Frog

The paid license is currently £199/year on Screaming Frog's UK pricing page, with an unlimited crawl limit; the free version is capped at 500 URLs. Screaming Frog

Another good option: Sitebulb Lite

Sitebulb Lite has a 10,000-URL-per-audit limit, which happens to match your site size almost exactly. It also detects broken links and redirect problems, including URLs redirecting to broken URLs and redirects back to themselves. Sitebulb Sitebulb

Its crawler lets you control threads and URLs/second, which is useful for running a relatively fast crawl without hammering your ecommerce server. Sitebulb Support

sitebulb.com

What I'd actually do

For your specific requirement, I'd start with Screaming Frog:

1. Crawl the XML sitemap + internal links, rather than relying exclusively on navigation.
2. Exclude faceted-search/parameter URLs that can explode the crawl.
3. Check:

• 4xx and 5xx URLs
• internal links pointing to redirects
• redirect chains
• redirect loops
• redirects ending in 4xx/5xx
• Export the offending URLs and fix them in batches.
• Run the crawl again after deployment.

For a 10k-page ecommerce site, don't let filters, sort parameters, internal search, or tracking parameters turn 10k pages into hundreds of thousands of crawl URLs. Screaming Frog provides controls for query strings and crawl limits specifically for this kind of situation. Screaming Frog

Budget-wise: if this is an occasional audit, Sitebulb Lite's 10k limit is attractive. If you're going to be doing regular technical crawls, I'd lean toward Screaming Frog's paid desktop license because you're not paying according to the number of URLs crawled.

One important distinction: if by "infinite redirect loops" you mean application-level loops that only occur for particular cookies, user agents, locales, or checkout states, I'd supplement the crawler with a small scripted HTTP check. A crawler can find normal HTTP redirect cycles, but it won't necessarily reproduce every state-dependent redirect bug.

Sitebulb Lite has a 10,000-URL-per-audit limit, which happens to match your site size almost exactly. It also detects broken links and redirect problems, including URLs redirecting to broken URLs and redirects back to themselves. sitebulb.com sitebulb.com

Its crawler lets you control threads and URLs/second, which is useful for running a relatively fast crawl without hammering your ecommerce server.

For a 10,000-page ecommerce site, I’d avoid heavyweight enterprise crawlers unless you need continuous monitoring across millions of URLs. For your specific goals — broken links + redirect loops/chains on a budget — these are the best fits:

1. Screaming Frog SEO Spider — best overall value

My pick for most 10k-page ecommerce sites. PipeRocket Digital

Why it fits:

• Crawls 10k+ URLs easily on a normal workstation
• Finds: - 404/410 broken links
• 5xx errors
• redirect chains
• redirect loops
• bad canonical targets
• orphaned pages (when combined with sitemaps/analytics)
• Exports clean CSVs your dev team can fix in bulk
• Lets you throttle crawl speed so you don't hammer your server PipeRocket Digital

Budget:

• Free version is useful for testing but limited to smaller crawls.
• Paid license removes the crawl limit and is usually far cheaper than enterprise SEO platforms. Marketraa

For your workflow:

1. Upload XML sitemap(s)
2. Crawl "List Mode" + normal crawl
3. Export: - Response Codes → Client Error (4xx)
4. Response Codes → Redirection (3xx)
5. Reports → Redirect Chains
6. Fix the highest-impact internal links first

2. Sitebulb — easier reports, less digging

Good if you need to hand findings to developers or non-SEO stakeholders. Bulk URL Checker

Pros:

• Better visualizations
• Prioritizes issues
• Makes redirect problems easier to understand
• Good for recurring audits Bulk URL Checker

Cons:

• Less raw-data oriented than Screaming Frog
• Costs more as crawl volume grows KrawlOps

3. Open-source/self-hosted option — lowest cash cost

If you have engineering resources, you can use:

• Python + requests + BeautifulSoup
• Scrapy
• Playwright (for JS-heavy storefronts)

You can build a crawler that records:

URL
HTTP status
redirect chain
final URL
canonical URL
anchor text
referring page
crawl depth

For ecommerce, this can actually be better because you can integrate:

• product database
• discontinued SKU rules
• inventory status
• redirect mapping tables

The downside is maintenance time.

What I would avoid for your case

• Enterprise crawlers like large cloud SEO platforms: great for huge sites, but overkill for 10k URLs unless you need daily monitoring, log analysis, or multiple teams.
• Browser-only broken-link checkers: they usually miss SEO-critical issues like canonical problems, redirect chains, and crawl depth.

My recommended budget setup

One-time audit:

• Screaming Frog paid license
• Crawl weekly/monthly manually

Ongoing ecommerce monitoring:

• Screaming Frog scheduled crawl (or a small custom script)
• Google Search Console monitoring
• Alert when: - 404s spike
• redirect chains exceed 1 hop
• important product/category URLs change status

For a 10k-page store, I’d start with Screaming Frog + your XML sitemap + a crawl export into Google Sheets/Jira. It gives you enterprise-level visibility without enterprise pricing. PipeRocket Digital

One question that changes the recommendation: is your store server-rendered (Shopify/Magento/WooCommerce style) or JavaScript-heavy (React/Next.js storefront)? The crawler settings differ quite a bit.

For a 10k-page ecommerce site, I’d use Screaming Frog SEO Spider if you want the best budget/performance tradeoff.

screamingfrog.co.uk is particularly good for this job because it can identify 404s, 5xx errors, redirects, redirect chains, and redirect loops. Its free version is limited to 500 URLs, while the paid version removes that limit; the current listed price is about £199/year (pricing can vary by currency). Screaming Frog Screaming Frog

My ranking

1. Screaming Frog — best overall for your use case

• Excellent at finding broken internal links.
• Explicitly detects redirect chains and loops.
• Can crawl your full 10k URLs rather than forcing you into a small cloud crawl quota.
• Lets you control crawl limits, depth, parameters, robots.txt behavior, etc. Screaming Frog Screaming Frog
• Best choice if you're comfortable running a desktop crawler.
• Sitebulb — best if you want easier reporting

• Particularly nice for visualizing and prioritizing technical problems.
• Reports broken redirects, self-referencing redirects, and chained redirect loops. Sitebulb
• Its Lite tier has a 10,000-URL total crawl limit, which is almost exactly your site size. Sitebulb
• It also lets you add your XML sitemap as a crawl source, which is useful for ecommerce sites. Sitebulb Support
• A custom script — cheapest at scale

• If you or your developer can run Python, a simple async HTTP crawler can check 10k URLs for 4xx/5xx, redirect chains, and loops for essentially the cost of your server.
• I'd use this for recurring automated monitoring, rather than replacing Screaming Frog entirely.

What I'd do for your site

Screaming Frog + sitemap + a small recurring script is probably the sweet spot.

Run Screaming Frog with:

Spider → Crawl Website
+
XML Sitemap URLs

Then specifically inspect:

• 4xx → broken pages
• 5xx → server problems
• 3xx → redirects
• Redirect Chains
• Redirect Loops
• Internal links pointing to redirected URLs
• Internal links pointing to 404/410 URLs

The important distinction is that you don't just want to find redirects. You want to find:

/product-a
   ↓ 301
/category-a
   ↓ 301
/category-b
   ↓ 200

and especially:

/product-a
   ↓ 301
/product-b
   ↓ 301
/product-a
   ↺ LOOP

Screaming Frog explicitly follows multiple redirect hops and identifies loops. Screaming Frog

For a 10k ecommerce site, I'd spend the ~$200/year on Screaming Frog rather than paying for a large cloud crawler. It's more than enough capacity for 10k pages, and you can also use it for canonical, pagination, hreflang, duplicate-content, metadata, and other technical audits. Screaming Frog

If you tell me your platform (Shopify, Magento, WooCommerce, custom, etc.) and whether you want this to run automatically every day/week, I can give you a very lean crawling setup that catches broken links + redirect loops + parameter/faceted-navigation explosions without hammering the server.

For a 10k-page ecommerce site, I’d use Screaming Frog SEO Spider if you’re okay running the crawler locally. It’s probably the best budget/performance choice for exactly this job.

My picks

1. Screaming Frog — best overall value

• Specifically detects 404s, 5xx errors, redirects, redirect chains and loops. Screaming Frog Screaming Frog
• The free version is capped at 500 URLs, so for your 10k pages you’d need the paid license. The current official pricing page lists $245/year (currency can vary by region). Screaming Frog
• Runs locally, which is nice for a budget-conscious ecommerce operation.
• You can export the broken URL and the pages linking to it, making remediation much faster.
• For redirect problems, it can crawl the redirect chain rather than merely telling you "this URL redirects."
• Sitebulb Lite — best inexpensive alternative

• Its Lite plan is limited to 10,000 URLs per audit, which is almost a perfect fit for your site. Sitebulb
• Current pricing information lists Lite at about $18/month. G2
• Much nicer visual reporting than Screaming Frog, but I'd still lean Frog for a technically focused broken-link/redirect investigation.
• Screpy — worth considering for ongoing monitoring

• It can crawl pages, links, redirects and broken-link signals, and lets you control max URLs, depth, concurrency and delays. Screpy
• I'd choose it if you want a cloud-based recurring monitor rather than a powerful desktop crawler for periodic audits.

What I'd actually do

For your situation, I'd spend the money on Screaming Frog and run a full crawl periodically.

Configure it roughly like this:

• Spider mode: crawl the website normally
• Follow redirects: enabled
• Respect robots.txt: initially yes
• Crawl canonicalized URLs: useful for ecommerce diagnostics
• JavaScript rendering: only enable if important links/products are generated client-side
• URL parameter handling: pay special attention to filters, sort parameters and tracking parameters
• Export: - 4xx
• 5xx
• redirect URLs
• redirect chains
• redirect loops
• inlinks to problematic URLs

The important ecommerce-specific point is not to blindly crawl every URL your faceted navigation can generate. A site with 10k products can suddenly become hundreds of thousands of crawlable parameter URLs. Sitebulb's documentation similarly notes that crawl-depth and URL limits are useful when pagination or URL structures can explode the crawl. Sitebulb Support

For infinite redirect loops specifically

I'd actually supplement the crawler with a tiny HTTP-level check. Crawlers are excellent at discovering the problem, but a simple script can rapidly test your entire URL inventory for:

URL → 301 → URL → 301 → ...

That lets you check all 10k URLs from your sitemap/database rather than relying only on URLs discovered through internal links.

Bottom line:
Screaming Frog paid if you want the strongest budget technical crawler. Sitebulb Lite if you prefer a simpler UI and want to stay around $18/month. For a 10k ecommerce site, I would not pay for an expensive enterprise crawler just to find broken links and redirect loops. Screaming Frog G2

If you tell me whether you're on Shopify, WooCommerce, Magento/Adobe Commerce, or custom, I can give you the exact crawler settings to avoid wasting requests on faceted URLs and still catch essentially every broken link/redirect loop.

For a 10k-page ecommerce site, I’d avoid expensive enterprise crawlers unless you need scheduled monitoring, log analysis, or multi-site reporting. Your requirements (broken links + redirect loops) are very well covered by a few budget-friendly options. theStacc Techcognate

My recommendation

1. Best overall budget choice: Screaming Frog SEO Spider

Best if you (or someone on your team) is comfortable analyzing exports. Marketraa

Why it fits:

• Handles 10k URLs easily on a normal laptop.
• Finds: - 404 broken links
• 5xx errors
• redirect chains
• redirect loops
• internal links pointing to redirects
• orphan/uncrawled pages (when paired with sitemaps)
• Gives you raw crawl data you can filter/export. PikaSEO
• The free version is limited, but the paid version removes the crawl cap. Marketraa

For your use case, I’d configure:

• Crawl source: Website + XML sitemap
• Crawl mode: Spider
• Follow redirects: enabled
• Crawl external links: enabled (but limit if your catalog has many outbound links)
• JavaScript rendering: enable if your storefront relies heavily on client-side navigation

Cost/value: excellent.

2. Easier reporting: Sitebulb

Better if you want the tool to explain problems rather than hand you spreadsheets. Sitebulb

Strengths:

• Very good at surfacing redirect problems visually.
• Prioritizes issues instead of giving you thousands of rows.
• Good for teams where the person fixing issues is not a technical SEO specialist. Sitebulb

For a 10k-page store, it is a comfortable fit. Sitebulb

3. Cheapest/free route: run an open-source crawler

If budget is extremely tight:

• Use an open-source crawler or a script-based crawler.
• Export URLs from: - XML sitemap
• database/catalog feed
• Google Search Console
• Check HTTP status codes and redirect chains.

The downside: you’ll spend more engineering time building reports and handling edge cases.

What I would do for an ecommerce site your size

A practical low-cost workflow:

1. Weekly automated check

• Crawl XML sitemap URLs.
• Alert on: - new 404s
• redirect loops
• redirect chains >1 hop
• product URLs returning unexpected statuses.
• Monthly deep crawl

• Run Screaming Frog.
• Compare against the previous crawl.
• Export: - Response Codes
• Redirect Chains
• Inlinks
• Orphan URLs
• Prioritize fixes

• Highest impact: 1. Product/category pages returning 404
• Internal links pointing to redirects
• Redirect loops
• Long redirect chains
• Broken image/script URLs

For a 10k-page ecommerce store, I’d start with Screaming Frog + your XML sitemap. It is likely enough, inexpensive, and gives you the technical detail needed to fix issues quickly. Marketraa

One question that would change the recommendation: is your ecommerce platform Shopify, Magento/Adobe Commerce, WooCommerce, BigCommerce, or custom-built? The best crawler settings differ quite a bit for faceted navigation and product variants.

For a 10k-page ecommerce site, I’d use Screaming Frog SEO Spider if your main goal is broken links + redirect loops on a budget.

My pick: Screaming Frog

screamingfrog.co.uk

Why it fits your use case:

• It specifically finds 404s, server errors, redirects, redirect chains, and redirect loops. Screaming Frog Screaming Frog
• It can follow a redirect chain all the way to the destination and identify loops, which is exactly the failure mode you're concerned about. Screaming Frog
• The free version handles 500 URLs; the paid license removes the crawl limit and is currently listed at £199/year. Screaming Frog
• For 10k URLs, that's relatively inexpensive compared with cloud-based enterprise crawlers.

A good alternative: Sitebulb

sitebulb.com

Sitebulb is arguably nicer for interpreting the results. Its Lite plan supports 10,000 URLs per audit, and it explicitly reports things like:

• internal URLs redirecting back to themselves
• chained redirect loops
• redirects to broken URLs
• broken internal links
• redirect chains with exportable details Sitebulb Sitebulb Sitebulb

So if your site is exactly around 10k URLs, Sitebulb Lite is worth considering. Its crawler also lets you control crawl speed and URL limits. Sitebulb Support

What I'd actually do

For your situation, I'd start with Screaming Frog paid and configure it like this:

1. Spider mode: crawl the entire site.
2. Crawl XML sitemaps: include your product/category sitemap URLs so orphaned ecommerce URLs aren't missed.
3. Follow redirects: enabled.
4. JavaScript rendering: only turn this on if important links are generated client-side; otherwise the normal HTML crawler will be substantially faster.
5. Export: - Internal Client Error (4xx)
6. All Redirects
7. Redirect Chains
8. Response Codes
9. Prioritize: - 404/410 URLs that have lots of internal links
10. redirects pointing to 404/410
11. redirect chains
12. redirect loops
13. internal links that point to redirects rather than directly to the final URL

For ecommerce, I'd not blindly crawl every parameterized URL (?sort=, filters, tracking parameters, etc.). Parameter explosions can turn a 10k-page site into hundreds of thousands of URLs. Start with canonical/indexable URLs and your XML sitemaps.

Bottom line:
Best budget choice → Screaming Frog.
Best easier-to-understand reporting → Sitebulb.
For just finding broken links and redirect loops, I wouldn't pay for an enterprise crawler.

For a 10k-page ecommerce site, I’d start with Screaming Frog SEO Spider. It is usually the best budget choice for exactly your use case: crawling every URL, finding broken links, and tracing redirect problems without paying for an enterprise crawler. It can identify broken links (404s/server errors) and audit redirects, including redirect chains and loops. Screaming Frog

My recommendation by budget

1. Best value: Screaming Frog SEO Spider

Best if: you (or someone on your team) can work with CSV exports.

Why it fits a 10k ecommerce site:

• Handles 10k URLs easily on normal hardware.
• Finds: - 404/410 broken pages
• broken internal links
• 301/302 chains
• redirect loops
• links pointing to redirected URLs
• canonical problems
• Gives you raw data developers can act on. Screaming Frog

Workflow I’d use:

1. Crawl your domain.
2. Export: - Response Codes → Client Error (4xx)
3. Response Codes → Redirection (3xx)
4. Reports → Redirect Chains
5. Bulk Export → All Inlinks
6. Fix: - internal links to 301s
7. redirect chains longer than 1 hop
8. loops (A → B → A or longer cycles)

For a 10k-page store, this is likely all you need.

2. Easier UI: Sitebulb

Best if: you want less manual analysis.

Sitebulb is better at turning crawl data into prioritized issues. It highlights things like broken internal links, links to redirects, and redirect problems in a more visual way. Sitebulb Sitebulb

Tradeoff:

• Easier for teams/non-SEO developers.
• More expensive than a simple Screaming Frog workflow.
• Less attractive if you mostly want raw crawl data.

3. Free/low-cost options (with limitations)

• Google Search Console

Good for Google-discovered errors, but it will not crawl your whole 10k-page catalog on demand.

• Open-source crawlers (e.g., custom scripts using Python + requests/aiohttp)

Cheapest, but you’ll spend engineering time building:

• retry logic
• JavaScript handling
• redirect tracking
• URL normalization
• reporting

For ecommerce, the time cost usually outweighs the savings.

Settings I’d use for your site

For a product catalog:

• Crawl mode: Spider
• User agent: Googlebot Smartphone (or compare against default)
• Follow redirects: enabled
• Crawl canonicals: enabled
• Crawl pagination/filter URLs carefully (faceted navigation can explode into millions of URLs)
• Respect robots.txt initially, then run a second diagnostic crawl if needed
• Limit query parameters: - /product?id=123
• /category?sort=price
• /filter?color=red

A common ecommerce failure is not broken links — it is accidentally crawling thousands of duplicate filter URLs.

My shortlist

For a 10k-page ecommerce site on a budget, I’d buy Screaming Frog first, run a weekly or biweekly crawl, and only move to a cloud crawler when you need scheduled monitoring, multiple sites, or millions of URLs. Screaming Frog Sitebulb

One extra tip: pair the crawler with a redirect log report from your application/server. Crawlers find what is linked internally; logs show what real users and bots are actually hitting. That combination catches far more ecommerce redirect problems.

For a 10k-page ecommerce site on a budget, my first choice would be Screaming Frog SEO Spider.

Best options

1. screamingfrog.co.uk — best value

• Specifically detects 404s, 5xx errors, redirects, redirect chains, and redirect loops. Screaming Frog Screaming Frog
• The free version handles 500 URLs, so for your full 10k crawl you'd need the paid license.
• The current paid license is £199/year and removes the URL limit. Screaming Frog
• Runs locally, so you're not paying based on crawl credits or server usage.
• Excellent for exporting the exact source URL → problematic URL → redirect chain information your developer needs.
• sitebulb.com — better UX, potentially more expensive

• Sitebulb Lite is capped at 10,000 URLs, which is almost exactly your site size. Sitebulb
• It has strong crawl controls and can use either a fast HTML crawler or Chrome for JS-heavy sites. Sitebulb Support
• I'd choose it if you want a more visual, guided technical-SEO audit rather than maximum bang-for-buck.

What I'd actually do

For your situation, I'd buy Screaming Frog and configure the crawl specifically for link/redirect auditing:

Spider mode
├── Crawl internal links: ON
├── Follow redirects: ON
├── Crawl canonicalised URLs: ON
├── Crawl XML sitemap: ON
├── JavaScript rendering: OFF initially
└── Respect robots.txt: ON

Then prioritize:

• 4xx → broken internal links
• 5xx → server/application problems
• 3xx chains → e.g. /old → /older → /new
• redirect loops → /a → /b → /a
• redirects to 404/5xx
• Internal links pointing to redirected URLs
• Sitemap URLs returning anything other than the intended 200
• Canonicals pointing through redirects or to broken URLs

Important ecommerce caveat: don't let a crawler blindly explode your URL count through faceted navigation (?color=, ?size=, sorting, filters, etc.). On a 10k-page store, parameterized URLs can turn a 10k crawl into hundreds of thousands of requests. Sitebulb specifically recommends controlling parameterized URLs when crawling larger sites. Sitebulb Support

If you tell me your platform (Shopify, Magento, WooCommerce, custom, etc.), I can give you the exact Screaming Frog configuration I'd use for a 10k-page store, including settings to catch redirect loops without getting trapped by faceted navigation.

For a 10,000-page ecommerce site, I’d use Screaming Frog SEO Spider as the default. It’s particularly good for your two specific problems: broken links and redirect loops.

My recommendation

Screaming Frog's paid version has an unlimited crawl limit and explicitly reports broken links, redirects, redirect chains, and redirect loops. Its current US price is $279/year. Screaming Frog Screaming Frog

The free version is limited to 500 URLs, so it isn't enough to crawl your entire 10k-page site in one pass. Screaming Frog

Why I'd pick Screaming Frog

For your use case, you don't really need an expensive enterprise crawler. Configure it to:

1. Crawl your XML sitemap - This is important for ecommerce because your sitemap may contain URLs that aren't easily discoverable through internal links.
2. Crawl internal links - Find 404s/410s, 5xx errors, and broken destinations.
3. Follow redirects - Screaming Frog can follow redirects through multiple hops.
4. Check Response Codes → Redirect Loops - It specifically identifies when a redirect eventually points back to a URL already encountered in the chain. Screaming Frog
5. Export Redirect Chains - You get the complete hop sequence rather than simply knowing that a redirect exists. Screaming Frog

I'd also run List Mode against your entire sitemap periodically. Screaming Frog supports importing URL lists and has an Always Follow Redirects option, which is particularly useful for systematically testing known URLs. Screaming Frog

If you want easier reporting

Sitebulb Lite is surprisingly compelling at this size. Its Lite plan supports 10,000 URLs per audit, exactly matching your site size, and is currently listed around $18/month. G2 Sitebulb

I'd choose:

• Screaming Frog → if you're technical and want maximum control/value.
• Sitebulb → if marketers/managers need to understand the reports without digging through raw crawl data.
• Neither enterprise cloud crawler → 10k URLs isn't remotely large enough to justify something like an enterprise crawling platform just for broken links.

The budget setup I'd actually use

Screaming Frog + your XML sitemap + a small recurring check.

For example:

Weekly:
  sitemap URLs
       ↓
Screaming Frog
       ↓
  ┌───────────────┐
  │ 4xx / 5xx     │ → fix broken links
  │ redirect loops│ → P0/P1 investigation
  │ redirect chains│ → consolidate
  │ redirect → 4xx│ → fix migration/config
  └───────────────┘

Then I'd have your application/CDN monitoring catch redirect loops between crawls. A crawler is excellent at discovering the problem, but it shouldn't be your only protection against a production redirect rule accidentally creating a loop.

Bottom line: spend the $279/year on Screaming Frog if this is an ongoing responsibility. For a 10k-page ecommerce site, that's probably the best cost-to-capability ratio. Screaming Frog

If you tell me what your ecommerce platform is (Shopify, Magento/Adobe Commerce, WooCommerce, BigCommerce, custom, etc.), I can give you a specific Screaming Frog configuration for finding broken links + redirect loops while minimizing crawl load.

For a 10k-page ecommerce site, I’d use Screaming Frog SEO Spider as the primary crawler if your goal is specifically broken links + redirect chains/loops, rather than paying for a full SEO suite.

My budget ranking

1. Screaming Frog SEO Spider — best overall

• Excellent at crawling 10k+ URLs locally.
• Finds 4xx/5xx errors, redirect chains, redirect loops, broken internal links, orphan-ish issues when combined with sitemaps/analytics, etc.
• You can crawl only what you need, which is useful for ecommerce sites where faceted URLs can explode the crawl.
• The free version is limited to 500 URLs, so for 10k pages you'd need the paid license.
• Ahrefs Site Audit — best if you already use Ahrefs

• Ahrefs currently gives verified sites 5,000 crawl credits/month free, and its crawler doesn't consume credits for 3xx, 4xx/5xx URLs or external URLs. Ahrefs Help Center Ahrefs Help Center
• Paid Lite currently includes 100,000 crawl credits/month and supports up to 25,000 pages per project. Ahrefs
• That's plenty for a 10k-page site, assuming your crawl configuration isn't causing huge URL expansion.
• Sitebulb — excellent UI, but I'd choose it mainly if you want deeper technical SEO analysis

• Particularly nice for diagnosing why problems occur, rather than simply generating a giant list of bad URLs.
• For your specific requirement, I don't think you need to pay for the extra sophistication unless you're doing regular technical audits.

What I'd actually do

For a budget-conscious 10k-page store:

Screaming Frog + a small custom HTTP checker is my preferred setup.

Use Screaming Frog to discover:

URL
→ status code
→ redirect target
→ final destination
→ redirect chain length
→ internal pages linking to it

Then flag:

4xx / 5xx
3xx → 3xx → 3xx
A → B → A
A → B → C → A
A → A
redirect chains > 2 hops

The important distinction is that a crawler should follow redirects and record the entire chain, not merely report that the starting URL returned 301.

One ecommerce-specific warning

Don't blindly crawl every discovered URL.

Faceted navigation can turn a nominal 10k-page site into hundreds of thousands or millions of crawlable URLs:

/category/shoes
/category/shoes?color=red
/category/shoes?color=red&size=10
/category/shoes?color=red&size=10&sort=price
...

I'd configure the crawler around your XML sitemap + internal HTML links, control URL parameters, and separately test parameterized URLs.

Bottom line: If you're buying one tool specifically for this job, Screaming Frog is my pick. If you already pay for Ahrefs, use Ahrefs Site Audit first—10k pages is comfortably within its current limits. Ahrefs Ahrefs Help Center

If you tell me your monthly budget (e.g. $0, $50, $100) and whether you're on Windows/Mac/Linux, I can give you the cheapest setup I'd use for a 10k-page ecommerce crawl.

For a 10k-page ecommerce site, I’d use Screaming Frog SEO Spider as the primary crawler, especially if your goal is specifically broken links + redirect loops rather than broader SEO monitoring.

My budget ranking

1. Screaming Frog SEO Spider — best value

• Excellent at finding 404s, 5xxs, redirect chains, redirect loops, orphaned URLs, bad canonicals, and internal links pointing to redirects.
• Runs locally, so you're not paying per URL every time you crawl.
• 10k pages is a very reasonable crawl size.
• Particularly good when you need to diagnose why a URL is looping rather than merely receive an alert.
• For your use case, I'd make this the main tool.
• ahrefs.com — best if you also want ongoing monitoring

• Ahrefs' current Site Audit can crawl sites up to 25,000 pages on its lower paid tier, and its crawler specifically reports broken links and redirects. Ahrefs Ahrefs Help Center
• The free account gives verified sites 5,000 crawl credits/month, so it isn't ideal for repeatedly crawling all 10k pages. Ahrefs Help Center
• Better choice if you already pay for Ahrefs for backlinks/keywords and want scheduled monitoring.
• sitebulb.com — excellent alternative

• Very good visualization and diagnostics, particularly for complicated site architectures.
• It lets you explicitly control maximum URLs and crawl depth, which can be useful on ecommerce sites with pagination/faceted navigation. Sitebulb Support
• I'd pick it over Screaming Frog if your team values reporting/visualization more than raw crawling flexibility.

For your particular problem

I'd actually run two types of crawl:

Normal internal crawl

Homepage
  ↓
Category
  ↓
Subcategory
  ↓
Product

Look for:

• 404 / 410
• 5xx
• internal links to 3xx
• redirect chains
• redirect loops
• canonical URLs returning errors
• links to URLs that eventually redirect
• products/categories linking to themselves through redirects

Then do a URL-list crawl using your sitemap(s) and product/category exports. This catches URLs that aren't reachable through normal internal navigation.

One ecommerce-specific trap

Don't let the crawler blindly explode into URLs like:

/category?color=red
/category?color=red&size=large
/category?sort=price
/category?page=999999

For a 10k-page store, faceted navigation can turn a seemingly small crawl into millions of URLs.

I'd configure the crawler to restrict parameters / control crawl depth, while separately testing a representative set of parameter URLs for redirect behavior.

If I were setting this up

$0–low budget: Screaming Frog + Google Search Console + sitemap URL list.

Already paying for Ahrefs: use Ahrefs for scheduled monitoring and Screaming Frog for deep investigations.

Need a dedicated crawler dashboard for a team: Sitebulb.

Bottom line: Screaming Frog is my pick for your 10k-page site. You don't need an enterprise crawler just to efficiently find broken links and redirect loops.

For a 10k-page ecommerce site, I’d use screamingfrog.co.uk as the default budget choice.

My recommendation

1. Screaming Frog — best value for your use case

• The paid version is currently $279/year in USD and removes the crawl limit. Screaming Frog
• It specifically detects 404s, server errors, redirects, redirect chains, and redirect loops. Screaming Frog Screaming Frog
• You can crawl the entire 10k site and export the source URL → problematic URL → final destination, which is exactly what you need for fixing internal links.
• It runs locally, so there aren't ongoing crawl-credit costs.
• For a 10k site, you don't really need an enterprise crawler.

2. Sitebulb Lite — good alternative

sitebulb.com

Sitebulb Lite allows 10,000 URLs per audit, making it almost perfectly sized for your site. Sitebulb It also has very nice visualization/prioritization, and JavaScript crawling is included. Sitebulb

I'd choose it over Screaming Frog if reporting and visual diagnostics matter more than having a highly configurable technical crawler.

For your specific problem

I'd configure Screaming Frog roughly like this:

1. Spider → Crawl your ecommerce domain.
2. Keep "Follow Internal Links" enabled.
3. Crawl your XML sitemap separately as well. This catches URLs that aren't necessarily discoverable through internal navigation.
4. Look at: - Response Codes → Client Error (4xx)
5. Response Codes → Server Error (5xx)
6. Reports → Redirect Chains
7. Redirect URLs / Redirect Chains
8. Pay particular attention to: - 301 → 301 → 200 — unnecessary chain
9. 301 → 302 → 200 — usually worth cleaning up
10. 301 → 301 → 301... — serious chain
11. A → B → A — redirect loop
12. A → B → C → A — multi-page loop

Screaming Frog explicitly supports following multiple redirects and identifying loops. Screaming Frog

One important ecommerce caveat

Don't blindly crawl every URL variant. Ecommerce sites can generate enormous numbers of URLs from:

• ?sort=
• ?filter=
• ?color=
• ?size=
• ?page=
• tracking parameters
• internal search
• faceted navigation

Otherwise your "10k-page site" can suddenly become a 100k+ URL crawl.

For your first audit, I'd crawl:

HTML pages + internal links + XML sitemap, while controlling parameter/faceted URLs.

If you want to spend $0

Screaming Frog's free version handles broken links and redirects but is limited to 500 URLs per crawl. Screaming Frog You could split your 10k site into 20 crawls, but honestly, for a production ecommerce site I'd consider the $279/year license cheap insurance.

Bottom line:
Screaming Frog paid → my pick. It's inexpensive, extremely good at exactly the broken-link/redirect-loop job, and 10k URLs is trivial for it. Sitebulb Lite → runner-up if you prefer a more guided audit/reporting experience.

If you tell me your stack (Shopify, Magento, WooCommerce, custom, etc.), I can give you the exact crawler settings for a 10k ecommerce site so you don't get killed by faceted-navigation/parameter URLs.

For a 10k-page ecommerce site, I’d avoid expensive enterprise crawlers. You’re in the sweet spot where a desktop crawler can do the job well. My shortlist:

Best budget choice: Screaming Frog SEO Spider

screamingfrog.co.uk

My pick for your use case. It is inexpensive, extremely configurable, and very good at finding:

• Broken internal links (404s)
• Broken external links
• Redirect chains
• Redirect loops
• Bad canonical targets
• 5xx errors
• Duplicate URLs
• Orphaned pages (when combined with sitemap/GSC data)

For a 10k ecommerce catalog, you can run a full crawl locally and export CSVs for developers. The main advantage is that you get raw crawl data instead of paying for a large SEO suite. palvdm.com Teksyte

Suggested settings for your site:

• Crawl mode: Spider
• Crawl only HTML pages initially
• Enable: - "Always follow redirects"
• "Crawl linked XML sitemaps"
• "Store HTML"
• User-agent: Googlebot Smartphone (for ecommerce realism)
• Speed: start around 2–5 requests/sec to avoid hammering your server
• Export: - Response Codes → Client Error (4xx)
• Response Codes → Redirection (3xx)
• Reports → Redirect Chains

Easier reporting option: Sitebulb

sitebulb.com

If you need non-technical teammates to understand issues, Sitebulb is excellent. It highlights problems with prioritized "hints" and visualizations, including broken links and redirect issues. Sitebulb Sitebulb

Tradeoff:

• Better UX/reporting
• Less raw forensic control than Screaming Frog
• Can cost more depending on your crawl needs KrawlOps

Free/cheap supporting tools

• search.google.com — free; good for seeing URLs Google actually encountered, but it is not a replacement for a full crawl.
• A small custom script using Python + requests can also check thousands of URLs cheaply, but it won't replace a crawler for internal link discovery.

What I would do for a 10k ecommerce site

1. Run Screaming Frog weekly or monthly.
2. Keep a saved crawl configuration so results are comparable.
3. Create three developer tickets automatically: - 404s with internal links pointing to them
4. Redirect chains >1 hop
5. Redirect loops
6. Crawl your XML sitemap separately and compare: - Sitemap URLs returning 200
7. Product URLs accidentally redirecting
8. Removed products returning the correct status (404/410/redirect)

For your size, I would not pay for enterprise crawlers like Botify, DeepCrawl/Lumar, etc. unless you need continuous monitoring across millions of URLs or multiple international storefronts.

One ecommerce-specific tip: make sure your crawler can handle faceted navigation (?color=, ?size=, filters, sorting URLs). A 10k-page store can accidentally become a million-URL crawl if those parameters are not controlled.

For a 10k-page ecommerce site, I’d use Screaming Frog SEO Spider. It’s probably the best budget/efficiency tradeoff for exactly this job.

My pick: Screaming Frog

screamingfrog.co.uk

• The paid version has an unlimited crawl limit (subject to your machine's resources) and currently costs $279/year. Screaming Frog
• It directly identifies 404/5xx broken links, redirect chains, and redirect loops. Screaming Frog Screaming Frog
• It can export the exact source URL → redirect chain → final destination, which is especially useful for handing fixes to developers.
• For 10k pages, a normal desktop/laptop should be more than adequate if you're primarily checking HTML responses rather than rendering every page in Chrome.

The free version only crawls 500 URLs, so you'd need the paid license for the whole site. Screaming Frog

How I'd configure it

For your specific objective, don't turn on every SEO audit feature. Keep the crawl lean:

1. Spider mode
2. Crawl internal HTML links.
3. Enable Always Follow Redirects.
4. Don't render JavaScript unless your ecommerce navigation/links genuinely depend on JS.
5. Start the crawl.
6. Check: - Response Codes → Client Error (4xx)
7. Response Codes → Server Error (5xx)
8. Response Codes → Redirect
9. Reports → Redirects → Redirect Chains
10. Filter the redirect-chain report for Loop = True. Screaming Frog Screaming Frog

For ecommerce specifically, I'd also watch for parameter explosions (?sort=, ?filter=, faceted navigation, session IDs, etc.). Those can make a nominal 10k-page site behave like a 100k+ URL crawl.

A good alternative: Sitebulb

sitebulb.com

Sitebulb is excellent if you want a more visual, management-friendly audit. Its Lite tier is capped at 10,000 URLs, while Pro can crawl substantially more on desktop. Sitebulb

For just broken links + redirect loops, though, I'd spend the money on Screaming Frog rather than Sitebulb. Screaming Frog's redirect-chain reporting is particularly well suited to your requirement.

If you're really trying to minimize cost

You could also build a tiny purpose-built crawler using Python/Go that:

URL
 ↓
HTTP request
 ↓
3xx? ──yes──> follow Location
 ↓              ↓
4xx/5xx        already_seen?
 ↓              ↓
broken          yes → LOOP
                no → continue

For 10k URLs, this is technically very easy and could run for essentially pennies. The downside is that you have to handle canonicalization, relative URLs, robots.txt, rate limiting, retries, compressed responses, malformed redirects, etc.

So my recommendation:

One important distinction: don't rely solely on crawling links from the homepage. For an ecommerce site, I'd feed the crawler your XML sitemap(s) + known URL inventory as well. That catches orphaned URLs that a normal link crawl won't discover.

For a 10k-page ecommerce site, I’d use Screaming Frog SEO Spider. It’s probably the best budget/efficiency tradeoff for exactly this job.

My recommendation

1. Screaming Frog — best overall

• Paid license is currently $279/year in USD and removes the 500-URL limit; the free version only crawls 500 URLs per crawl. Screaming Frog Screaming Frog
• It specifically detects 404s, 4xx/5xx errors, redirects, redirect chains, and redirect loops. Screaming Frog Screaming Frog
• It can crawl up to 5 million URLs with a licensed configuration, so 10k pages is trivial. Screaming Frog
• Windows, Mac, and Linux.

For your use case, I wouldn't pay for a much more expensive enterprise crawler unless you need scheduled cloud crawling, multiple users, or very large sites.

screamingfrog.co.uk

A good alternative: Sitebulb

Sitebulb Lite is another strong option because its audit limit is 10,000 URLs, exactly matching your site size. It also has a 14-day fully featured trial. Sitebulb Sitebulb Support

I'd choose Sitebulb if you want more visual reporting and easier-to-understand issue prioritization. For a technical person who mainly wants to hunt down broken links and redirect problems, I still prefer Screaming Frog.

sitebulb.com

How I'd configure the crawl

For your specific objective, don't just crawl everything blindly. I'd run:

1. Internal HTML crawl
2. Enable follow redirects
3. Export: - 4xx URLs
4. 5xx URLs
5. 3xx URLs
6. redirect chains
7. redirect loops
8. source URL → broken/redirected destination
9. Crawl your XML sitemap separately and compare it against the discovered URLs.
10. Crawl important product/category URLs from your database/feed even if they're not currently linked internally.

The particularly useful thing about Screaming Frog here is that it can follow multiple redirects through to the final destination and identify loops, rather than merely telling you that a URL returned a 301/302. Screaming Frog

One important ecommerce caveat

On a 10k-page store, URL parameters can make a "10k page site" effectively a 100k+ URL crawl—think ?sort=, filters, tracking parameters, faceted navigation, etc.

I'd configure the crawler to control/exclude unnecessary parameter combinations. Otherwise you can spend most of your crawl budget discovering combinations that aren't actual pages.

Bottom line:
$279/year Screaming Frog + a carefully configured crawl is what I'd buy. If you only need this as a one-off, use the free version against carefully selected URL lists, or use the trial of Sitebulb. For ongoing ecommerce technical monitoring, Screaming Frog gives you considerably more control for the money.

For a 10k-page ecommerce site, I’d prioritize a crawler that can reliably find:

• broken internal links (404/410)
• server errors (5xx)
• redirect chains
• redirect loops
• links pointing to redirected URLs
• canonical/hreflang issues
• parameter traps (very common in ecommerce)

On a budget, these are the best options:

1. Screaming Frog SEO Spider — best overall value

screamingfrog.co.uk

My pick for most 10k-page ecommerce sites.

Why:

• Handles 10k+ URLs easily on a normal laptop.
• Excellent at finding broken links and redirect problems.
• Lets you export exactly what developers need (source URL → broken URL → anchor text).
• Can crawl JavaScript-rendered sites if configured properly.
• Very good for ecommerce patterns like faceted navigation, duplicate URLs, and redirect audits. Screaming Frog

Best settings:

• Crawl: Internal HTML only first
• Follow redirects: enabled
• Store HTML: enabled
• Crawl all subdomains only if needed
• Limit URL parameters (otherwise ecommerce filters can explode the crawl)

For a 10k site, the workflow would be:

1. Crawl the site.
2. Go to: - Response Codes → Client Error (4xx) → broken links
3. Response Codes → Redirection (3xx) → redirect chains
4. Reports → Redirect Chains → loops/chains
5. Export CSV for fixes.

Cost: the paid version is usually far cheaper than enterprise crawlers, and the free tier is mainly for smaller crawls. Screaming Frog

2. Sitebulb — best if you want easier reports

sitebulb.com

Better if you need to hand findings to non-technical teams.

Pros:

• Very clear dashboards.
• Automatically prioritizes issues.
• Good visualization of link problems.
• Finds broken links, internal links to redirects, and redirect issues. Sitebulb

Cons:

• More expensive than a simple Screaming Frog workflow.
• Less appealing if you want raw crawl data and custom analysis.

Sitebulb

3. Free/low-cost options

Google Search Console

Good supplement, not a replacement.

Use it for:

• URLs Google actually failed on
• crawl/indexing issues
• pages returning errors

Weakness:

• It won't systematically crawl all 10k pages.

Self-hosted crawlers

If you have engineering resources, you can build around:

• Python + Scrapy
• Playwright (for JS-heavy ecommerce)
• custom URL queue + redirect tracker

This can be cheap but requires maintenance.

My recommended stack for your situation

For a 10k ecommerce store:

Monthly technical audit

• Screaming Frog crawl
• Export: - 404s
• 5xx errors
• redirect chains
• orphaned pages
• internal links to redirects

Continuous monitoring

• Google Search Console
• Server logs (if available)

Before migrations or major catalog changes

• Screaming Frog crawl before + after
• Compare URL lists

A few ecommerce-specific crawler settings matter a lot:

• Set a maximum URL depth (prevents filter loops).
• Exclude URLs with tracking parameters (?utm, ?sort=, etc.).
• Watch faceted navigation (color=, size=, filter=) because it can create millions of crawlable URLs.
• Crawl with JavaScript only when needed; it can multiply crawl time.

For a 10k-page store, I would start with Screaming Frog + a carefully tuned crawl configuration rather than paying for an enterprise crawler. Screaming Frog piperocket.digital

A few ecommerce-specific crawler settings matter a lot:

For a 10k-page ecommerce site, I’d use Screaming Frog SEO Spider if you’re okay spending roughly $279/year; if you want to stay especially budget-conscious, Sitebulb Lite is also worth considering.

My pick: Screaming Frog

screamingfrog.co.uk is particularly well suited to your exact problem:

• Broken links: finds 404s/5xx errors and gives you the source pages linking to them. Screaming Frog
• Redirect chains: follows multiple 3xx hops and reports the chain.
• Redirect loops: explicitly identifies loops where a redirect eventually points back to a previous URL. Screaming Frog Screaming Frog
• 10k URLs is trivial: the paid version removes the 500-URL free limit; the current listed price is $279/year for one license. Screaming Frog
• It runs locally, so you're not paying per crawl/URL.

For a site your size, that's a pretty good cost/performance ratio.

If you want cheaper: Sitebulb Lite

sitebulb.com is another strong choice. Its Lite plan allows 10,000 URLs in total, so you're right at its stated limit. It specifically reports broken/redirected internal links and can export redirect chains. Sitebulb Sitebulb Support

I'd choose Sitebulb if you value its reporting/visualization more than raw crawler flexibility.

What I'd actually do

For your use case, I'd set up Screaming Frog in Spider mode:

1. Crawl the XML sitemap(s) rather than relying exclusively on internal discovery.
2. Crawl all 10k product/category/content URLs.
3. Check Response Codes → Client Error (4xx) for broken links.
4. Check Response Codes → Redirect and run crawl analysis.
5. Export Redirect Chains and filter for Loop = True.
6. Also look for: - redirects → 404/5xx
7. chains with 2+ hops
8. internal links pointing directly to redirected URLs
9. canonical → redirect
10. redirect → canonical
11. HTTP ↔ HTTPS loops
12. trailing-slash/non-trailing-slash loops
13. parameterized URLs creating crawl traps

Screaming Frog's redirect reports can map the entire chain and identify loops, which is exactly what you need. Screaming Frog

One important ecommerce caveat: don't blindly crawl every URL your site can generate. Faceted navigation, sorting parameters, internal search, tracking parameters, and session URLs can turn a nominal 10k-page site into hundreds of thousands or millions of crawlable URLs. I'd configure exclusions for those before starting.

Bottom line:
Best budget choice → Screaming Frog. At 10k pages, I'd spend the ~$279/year rather than trying to stitch together multiple free tools. If $0 is an absolute requirement, you can use the free 500-URL version strategically, but it won't give you a complete 10k-page audit. Screaming Frog

For a 10k-page ecommerce site, I’d use Screaming Frog SEO Spider first. It’s probably the best budget-to-capability choice for exactly the problems you described.

My recommendation

Screaming Frog's current paid license is $279/year and removes the 500-URL limit. It specifically supports broken-link/error detection and redirect-chain/loop auditing. Screaming Frog Screaming Frog

Sitebulb Lite is another interesting budget option: its limit is 10,000 URLs per audit, and it has dedicated reports for broken links and redirect chains. Sitebulb Sitebulb Support

Why I'd pick Screaming Frog

For your particular use case, you don't really need an expensive enterprise crawler.

I'd configure Screaming Frog to:

• Crawl HTML only initially.
• Enable crawl all subdirectories.
• Start from the homepage and your XML sitemap.
• Exclude unnecessary query parameters, especially ecommerce faceted-navigation URLs.
• Filter Response Codes for 4xx and 5xx.
• Inspect Redirects → Redirect Chains.
• Export Inlinks for every broken URL so you know exactly which pages need fixing.
• Run a separate crawl of your XML sitemap URLs to catch URLs that aren't necessarily discoverable through internal links.

This is particularly important on ecommerce sites because faceted navigation can turn a 10k-page site into hundreds of thousands of crawlable URL variations. Sitebulb's own large-site guidance specifically calls out parameterized URLs as a potential source of crawl bloat. Sitebulb Support

For redirect loops specifically

Don't just look for 301/302 responses.

You want to identify patterns like:

/product-a
   ↓ 301
/product-b
   ↓ 302
/category-x
   ↓ 301
/product-a
   ↺ LOOP

and chains such as:

/old-product
 → /old-product-2
 → /product
 → /product-final
 → 200

The first is an outright failure; the second wastes crawl resources and adds latency. Google Search Console also treats each server-side redirect in a chain as a separate request, and explicitly notes that abandoned requests due to redirect loops appear in Crawl Stats. Google Support

The cheapest setup I'd use

$0: Start with Screaming Frog's free version to validate your configuration. It only crawls 500 URLs per crawl, but it includes broken links and redirect analysis. Screaming Frog

~$279/year: Buy one Screaming Frog license and crawl the entire 10k site. That's what I'd choose if you're doing this regularly.

~$18/month: Sitebulb Lite is worth considering if you strongly prefer a more visual/easier-to-understand interface. Its 10k-URL limit happens to match your site almost perfectly. G2

Free supplement: Google Search Console's Crawl Stats can show you what Googlebot is actually encountering, including server errors, redirects and abandoned requests from redirect loops. Google Support

Bottom line: Screaming Frog + Google Search Console would be my pick. For a 10k ecommerce site, I'd spend the $279/year rather than paying for an enterprise crawler.

If you tell me whether the store is Shopify, Magento/Adobe Commerce, WooCommerce, BigCommerce, or custom, I can give you a crawl configuration specifically designed to avoid blowing up the crawl with faceted URLs.

For a 10k-page ecommerce site on a budget, I’d use Screaming Frog SEO Spider as the default choice.

My ranking

1. screamingfrog.co.uk — best value

• The free version handles 500 URLs; the paid license removes the crawl limit and is currently £199/year (about $279/year on the US pricing page). Screaming Frog Screaming Frog
• Specifically detects broken links, HTTP errors, redirects, redirect chains and redirect loops. Screaming Frog
• Runs locally, so you aren't paying per URL/crawl credit.
• For 10k pages, this is probably the sweet spot if you're comfortable installing desktop software.
• sitebulb.com — best if you want easier reporting

• Sitebulb Lite is limited to 10,000 URLs per audit, which fits your site almost exactly. Sitebulb
• Its cloud product emphasizes fixed pricing rather than crawl credits, and it can handle much larger sites. Sitebulb
• I'd choose it over Screaming Frog if non-technical stakeholders need polished explanations/reports.
• ahrefs.com — good if you already use Ahrefs

• The free verified-site account currently includes 5,000 crawl credits/month, so it isn't quite enough to cover a 10k-page site in one full crawl. Ahrefs Help Center
• Its crawler doesn't charge crawl credits for 3xx, 4xx/5xx URLs or external resources, which makes redirect/broken-link investigation relatively efficient. Ahrefs
• Paid plans give substantially larger crawl limits. Ahrefs

For your specific problem

I'd configure Screaming Frog roughly like this:

Spider → Crawl

• Start from the homepage and import your XML sitemap.
• Enable crawling of internal links.
• Crawl HTML only initially if your primary objective is links/redirects.
• Follow redirects.
• Don't immediately let URL parameters explode the crawl. Ecommerce faceted navigation can turn a nominal 10k-page site into hundreds of thousands of URLs.
• Export: - Internal > Client Error (4xx)
• Internal > Redirection (3xx)
• Reports > Redirect Chains
• URLs linking to each problematic URL.

The important distinction is that you don't just want a list of 404s. You want the source URL → redirect → redirect → destination chain, because that's where redirect loops and unnecessarily long chains become obvious.

For a 10k-page ecommerce site, I'd also do a second crawl from the XML sitemap rather than relying solely on the homepage crawl. That catches URLs that exist in your sitemap but aren't internally linked.

Bottom line: if you want to spend the least while still getting a serious crawler, buy Screaming Frog for the year. At roughly $279/year, it's dramatically cheaper than most cloud SEO platforms and is purpose-built for exactly this sort of technical crawl. Screaming Frog

If you tell me whether your store is Shopify, Magento, WooCommerce, BigCommerce, or custom, I can give you a crawl configuration specifically designed to catch faceted-navigation explosions + redirect loops + broken internal links without hammering the server.

For a 10k-page ecommerce site, I’d avoid expensive enterprise crawlers. You’re in the sweet spot where a desktop crawler can handle the job easily and give you the data you need.

My recommendations:

Best overall budget choice: Screaming Frog

RingCentral CallWhy I’d pick it for your case:

• Excellent at finding: - 404 broken internal links
• 5xx errors
• redirect chains
• redirect loops
• incorrect canonical targets
• links pointing to redirected URLs
• Handles 10k URLs comfortably on a normal laptop.
• Gives you raw exports developers can actually work from (CSV/Excel).
• Good for recurring ecommerce audits.

The workflow I’d use:

1. Crawl the site in Spider mode.
2. Check: - Response Codes → Client Error (4xx) → broken links
3. Response Codes → Redirection (3xx) → redirect issues
4. Reports → Redirect Chains → chains/loops
5. Export: - “All Redirects”
6. “Response Codes”
7. “Bulk Export → Response Codes → Inlinks”

For a 10k-page store, this is probably the best cost-to-capability ratio. Teksyte

Easier UI option: Sitebulb

SitebulbChoose this if:

• Your team is less technical.
• You want dashboards instead of spreadsheets.
• You need reports that explain issues to marketing/dev teams.

Strengths:

• Prioritized “Hints” for problems.
• Good visualizations.
• Strong link auditing and redirect issue reporting. Sitebulb

For pure debugging, I’d still lean Screaming Frog; for communicating findings, Sitebulb is often nicer.

Cheapest/free approaches

Google Search Console

search.google.com

Good for:

• Google-discovered 404s
• indexing problems

Not enough by itself because it won’t crawl your entire internal link graph on demand.

Open-source crawler stack

If you have engineering resources:

• Crawl with something like a custom script using Python + requests/BeautifulSoup or Playwright.
• Store URLs/status codes in SQLite/Postgres.
• Run nightly.

This is cheapest long-term, but usually costs more engineering time than a $200-ish crawler license.

For an ecommerce site specifically, I’d add these checks

A broken-link crawl alone misses common ecommerce SEO problems:

• Product URLs returning 200 but showing “out of stock/deleted” pages.
• Category pages linking to discontinued products.
• Redirect chains caused by migrations.
• Faceted navigation generating infinite URL combinations.
• Canonicals pointing through redirects.
• Internal links still pointing at old URLs.

My practical setup:

For a 10k-page ecommerce store on a budget, I’d start with Screaming Frog paid license + a monthly automated crawl. It’s enough scale without paying for enterprise SEO crawlers. growwithba.com

For a 10k-page ecommerce site, I’d use Screaming Frog SEO Spider as the default—especially if “budget” means roughly <$300/year.

My pick: Screaming Frog

Screaming Frog SEO Spider is particularly well suited to your two problems:

• Broken links: finds 4xx/5xx responses and shows the pages linking to them.
• Redirect chains: identifies URLs passing through multiple redirects.
• Redirect loops: specifically reports redirect loops rather than just treating them as generic errors.
• 10k URLs: the paid license removes the 500-URL limit. The current listed price is $279/year in USD. Screaming Frog Screaming Frog
• Fast/local: it runs on your own machine, so you're not paying for cloud crawl credits.
• You can export the problematic URLs and their source pages for your dev team.

screamingfrog.co.uk

The free version is useful for testing, but its 500-URL crawl limit makes it unsuitable for a complete 10k-page crawl. Screaming Frog

Runner-up: Sitebulb

Sitebulb is nicer if you want a more guided, visual audit. Its Lite plan supports 10,000 URLs per audit, so it happens to line up almost perfectly with your site size. Current third-party pricing lists Lite around $18/month, although I'd verify the current price before purchasing. Sitebulb G2

sitebulb.com

I'd choose Sitebulb over Screaming Frog if your team cares more about easy-to-understand reports and prioritization than maximum crawler control.

What I'd actually do

For your specific use case:

For a budget-conscious technical SEO workflow, I'd spend the ~$279/year on Screaming Frog and skip the expensive enterprise crawlers. Screaming Frog

One important ecommerce-specific tip: don't just crawl the 10k URLs from your sitemap. Configure the crawler to follow internal links and separately crawl your XML sitemap. That lets you catch both broken internal links and URLs that are in the sitemap but effectively unreachable from the site's link graph.

If your site has faceted navigation, search URLs, tracking parameters, or JavaScript-generated links, I can also give you a Screaming Frog configuration for a 10k-page ecommerce crawl that minimizes crawl time and avoids getting trapped in parameter/infinite URL loops.

For a 10k-page ecommerce site, I’d use Screaming Frog SEO Spider if your priority is specifically broken links + redirect chains/loops at the lowest cost.

My pick: Screaming Frog

screamingfrog.co.uk is particularly well suited to this job:

• It explicitly detects 404s/server errors and redirects, including redirect chains and loops. Screaming Frog
• The free version is limited to 500 URLs, so for 10k pages you'd need the paid license.
• The current paid price is $279/year in USD, with an unlimited crawl limit subject to your machine's resources. Screaming Frog
• It runs locally, so you aren't paying for a cloud crawl every time.
• For this particular task, you don't need JavaScript rendering, PageSpeed, accessibility checks, etc. HTML crawling is much faster and cheaper on resources.

Good alternative: Sitebulb Lite

sitebulb.com is worth considering if you want a more visual, guided audit.

Its Lite plan supports 10,000 URLs per audit, exactly matching your current site size. Sitebulb Sitebulb It can also use XML sitemaps and other URL sources, which is useful for ecommerce sites where not every URL is internally linked. Sitebulb Support

I'd still choose Screaming Frog for your stated use case because it's more focused and gives you a lot of control over exactly what you're crawling.

For maximum efficiency, I'd configure the crawl like this

Screaming Frog → Spider mode → HTML crawl

1. Start with your XML sitemap(s) as a crawl source in addition to the homepage.
2. Crawl HTML only initially.
3. Turn off unnecessary resource crawling.
4. Set a reasonable crawl speed so you don't hammer your production server.
5. Examine: - Response Codes → Client Error (4xx)
6. Response Codes → Server Error (5xx)
7. Reports → Redirect Chains
8. Reports → Redirect Loops
9. Internal links pointing at redirects
10. Export the problematic URLs with their source URLs so developers can fix the actual links rather than merely knowing that a destination is broken.

For an ecommerce site, I'd pay particular attention to redirect chains involving product/category URLs. A common pattern is:

old product URL → old category URL → canonical URL → final product URL

Even though the customer eventually gets there, you're making crawlers and users follow unnecessary hops.

One important trick

Don't rely solely on crawling from your homepage. For a 10k-page ecommerce site, combine:

Internal crawl + XML sitemap + Search Console URLs

That catches URLs that are in your sitemap or have historically been indexed but aren't currently reachable through your internal link graph. Sitebulb explicitly supports adding sitemap, Analytics and Search Console URLs as crawl sources. Sitebulb Support

Bottom line:
Screaming Frog paid is my recommendation if you're comfortable with a desktop crawler and want the cheapest serious solution. Sitebulb Lite is the alternative I'd pick if you value a more guided interface and visual reporting. For just broken links and redirect loops, I wouldn't spend money on an enterprise crawler.

For a 10k-page ecommerce site, I’d prioritize a crawler that can handle:

• broken internal links (404/410)
• redirect chains
• redirect loops
• bad canonicals
• orphaned product/category pages
• JavaScript-rendered links (if your storefront uses React/Vue/etc.)
• scheduled repeat crawls

On a budget, these are the best options:

CrawlBudget Sitebulb## My recommendation: Screaming Frog first

For a 10k-page store, I’d start with Screaming Frog SEO Spider paid license.

Why:

• It easily handles 10k+ URLs.
• It gives you the raw crawl data developers need.
• It finds: - 404 pages
• 5xx errors
• redirect chains
• redirect loops
• links pointing to redirects
• broken external links
• bad canonical targets
• You can export CSV files and hand fixes directly to engineering. Teksyte PikaSEO

A typical workflow:

1. Crawl the whole domain.
2. Go to Response Codes → Client Error (4xx).
3. Export broken URLs.
4. Go to Response Codes → Redirection (3xx).
5. Check: - redirects with more than one hop
6. loops
7. internal links pointing to redirected URLs
8. Fix the source links, not just the redirects.

If you want less manual analysis: Sitebulb

For ecommerce teams where marketing, SEO, and developers all need to consume reports, Sitebulb is very good. It emphasizes prioritized issues and visualizations rather than just giving you thousands of rows of crawl data. It can also identify internal link issues and redirect problems. Sitebulb Sitebulb

Budget stack I’d use

For your size site:

Option A — cheapest professional setup

• Screaming Frog paid license
• Google Search Console
• Google Sheets/Excel for fix tracking

Option B — more automated

• Screaming Frog for monthly deep crawls
• Search Console for Google-discovered errors
• A small script/job that checks your sitemap URLs weekly

Option C — if your catalog changes constantly

• Add a crawler with scheduled monitoring (Sitebulb Cloud or similar) so new product/category issues are caught automatically. Sitebulb

One thing I’d avoid: relying only on Google Search Console. It catches some broken URLs Google has discovered, but it will not reliably tell you about every bad internal link, redirect loop, or broken path in a 10k-page ecommerce architecture.

If you tell me your stack (Shopify, Magento, WooCommerce, custom React/Next.js, etc.) and how often products change, I can suggest the crawl settings and schedule.

For a 10k-page ecommerce site on a budget, I’d use Screaming Frog SEO Spider.

screamingfrog.co.uk

My picks

• 🥇 Screaming Frog — best overall value. It specifically detects broken links, 4xx/5xx errors, redirect chains and redirect loops. The free version is limited to 500 URLs, but the paid license removes the crawl limit; the current US price is $279/year. Screaming Frog Screaming Frog
• 🥈 Sitebulb — best if you want a nicer UI. Its desktop version supports audits up to 500k URLs, and it has dedicated reporting for broken links and redirect chains. Its Lite tier is listed at $18/month for up to 10,000 URLs per audit. G2 Sitebulb Support
• 💰 Greenflare — cheapest/free option. It's open-source, runs locally, has low hardware requirements, and reports 3xx/4xx/5xx responses and broken internal links. It's worth considering if you're comfortable with a less polished technical tool. PyPI

What I'd do for your site

For 10k URLs, I'd spend the money on one Screaming Frog license rather than an expensive cloud SEO platform. You don't need enterprise crawling infrastructure for 10k pages.

Configure it roughly like this:

1. Spider your site from the homepage so it discovers links naturally.
2. Enable Crawl All Subdomains only if relevant to your ecommerce architecture.
3. Crawl internal links and check the Response Codes report for 404, 410, 500, etc.
4. Check the Redirects / Redirect Chains report specifically for chains and loops. Screaming Frog can also crawl a supplied URL list, which is useful for testing old product/category URLs from your database or sitemap. Screaming Frog
5. Export the errors with their source URLs, so developers can fix the actual links rather than just the destination.
6. Run it periodically after deployments or catalog migrations.

One important ecommerce wrinkle: don't rely solely on a homepage crawl. I'd also feed Screaming Frog your XML sitemap(s) and, ideally, a URL export from your product/category database. That catches URLs that are no longer internally linked but are still live in search, feeds, ads, or old external links.

If $0 is an absolute requirement, I'd try Greenflare first. If you can spend ~$23/month equivalent, Screaming Frog is the tool I'd choose for this particular job.

For a 10k-page ecommerce site, I’d use Screaming Frog SEO Spider if you can spend ~$279/year. It’s probably the best budget-to-capability choice for exactly this job. Its paid version explicitly checks broken links/errors and redirects, supports redirect analysis, JavaScript rendering, crawl configuration, and has an unlimited crawl limit subject to your machine’s resources. Screaming Frog

My picks

1. screamingfrog.co.uk — best overall

• Cost: $279/year for one license currently. Screaming Frog
• Easily handles 10k URLs.
• Excellent for finding 404s, 3xx redirects, redirect chains, redirect loops, and broken internal links.
• You can crawl without rendering JavaScript, which makes large ecommerce crawls much faster.
• For your use case, I'd configure it primarily as an HTML crawler and only enable JS rendering if your links are generated client-side.
• sitebulb.com — best if you want easier reporting

• Its Lite plan supports exactly 10,000 URLs per audit, so your site is right at the limit. Sitebulb Sitebulb
• Better visualizations and issue prioritization than Screaming Frog.
• The Pro version jumps to 500k URLs, but that makes less sense if you're trying to keep costs down.
• It can explicitly control crawl speed, threads, and maximum URLs/second. Sitebulb Support
• ahrefs.com — best $0 option

• You get 5,000 crawl credits/month per verified project. Ahrefs
• Importantly, redirects and broken URLs don't consume those credits; only successfully crawled HTML pages do. Ahrefs
• Ahrefs specifically reports redirect chains and loops as crawlability issues. Ahrefs
• But for a 10k-page site, you're limited to roughly half the site per month if all 10k pages need to be crawled.

What I'd actually do

If this were my site:

$0: Start with Ahrefs Free and run it against the verified domain.

~$23/month equivalent: I'd probably buy Screaming Frog for the year instead. The ability to repeatedly crawl the whole 10k-site locally is much more useful than rationing 5k Ahrefs crawl credits.

For specifically hunting infinite redirect loops, I'd make the crawler check these separately:

200 → normal
301 → 200       ✓
301 → 301 → 200   fix to direct 301 → 200
301 → 302 → 200   usually fix
301 → 301 → 301 → ...   redirect chain/loop
301 → same URL    redirect loop
A → B → A        redirect loop

Also crawl from both directions: start from the homepage and crawl internal links, but separately upload your XML sitemap/product URL list as crawl seeds. Ecommerce sites often have discontinued products, faceted URLs, and old category URLs that aren't reachable through current navigation but can still contain broken redirects.

Bottom line: Screaming Frog is my recommendation for a 10k ecommerce site on a budget. Ahrefs Free is the sensible zero-dollar starting point; Sitebulb is the better choice if ease of interpreting the crawl matters more than squeezing out the lowest cost.

For a 10k-page ecommerce site, I’d use Screaming Frog SEO Spider first. It’s probably the best budget/performance sweet spot for exactly this job.

My recommendation

1. screamingfrog.co.uk — best overall - Specifically detects 404s, 5xx errors, redirects, redirect chains, and redirect loops. Screaming Frog
2. The free version only crawls 500 URLs, so your 10k site requires the paid license.
3. Current paid price is £199/year for one license, with an effectively unlimited crawl limit subject to your machine's RAM/storage. Screaming Frog
4. Runs locally, so you're not paying based on every URL crawled.
5. For a 10k ecommerce site, that's substantially cheaper than most enterprise/cloud crawlers.

1. sitebulb.com — best if you want easier reporting - Its link auditing explicitly identifies broken internal links and internal links to redirects. Sitebulb
2. Sitebulb Lite supports exactly 10,000 URLs per audit, which makes it an interesting budget option if your site reliably stays under that threshold. Sitebulb
3. Pro goes to 500k URLs per audit. Sitebulb
4. I'd choose this over Screaming Frog if non-technical stakeholders need to consume the reports.

For your particular problem

I'd configure Screaming Frog roughly like this:

Mode: Spider
Start URL: https://www.example.com/
Follow internal links: Yes
Follow external links: Optional
JavaScript rendering: Only if your navigation/products require JS
Respect robots.txt: Yes initially
Crawl limit: ~25,000–50,000

Don't set the crawl limit to exactly 10,000. Ecommerce sites commonly generate URLs through filters, sort parameters, tracking parameters, faceted navigation, etc. You want enough headroom to discover problematic URLs without accidentally crawling millions of combinations.

Then inspect:

• Response Codes → Client Error (4xx)
• Response Codes → Server Error (5xx)
• Response Codes → Redirection (3xx)
• Reports → Redirect Chains
• Reports → Redirect Loops
• Bulk Export → Response Codes → Client Error / Redirection

The important distinction is that you want to find both:

A. Bad destination

Product page
   ↓
301
   ↓
301
   ↓
404

and the more serious:

B. Actual loop

/product-a
   ↓
301 → /product-b
   ↓
301 → /product-a
   ↺

One ecommerce-specific trick I'd strongly recommend

Don't rely solely on crawling from the homepage.

Feed Screaming Frog your XML sitemap(s) as well. For a 10k ecommerce site, I'd ideally crawl:

1. Internal-link crawl
2. XML sitemap URLs
3. Important URLs from Google Search Console
4. Product/category URLs from your database/feed, if available

That catches orphaned products that exist in your sitemap/database but aren't reachable through your site's internal links.

Cheapest setup

If I were managing this site myself:

$199/year → Screaming Frog + scheduled crawl + XML sitemap + GSC URL exports

That's what I'd start with. You don't need an expensive enterprise crawler for 10k pages.

If the site grows into hundreds of thousands/millions of URLs or you need centralized scheduled crawling, then I'd look at Sitebulb Cloud; its cloud product is designed for much larger crawls without being constrained by your workstation. Sitebulb Sitebulb

Bottom line: for 10k pages + broken links + redirect loops + budget, Screaming Frog is my first choice. Sitebulb is the runner-up if reporting/usability matters more than squeezing out the lowest cost.

The important distinction is that you want to find both:

A. Bad destination

One ecommerce-specific trick I'd strongly recommend

Don't rely solely on crawling from the homepage.

For a 10k-page ecommerce site, I’d use Screaming Frog SEO Spider if you’re comfortable running a desktop crawler. It’s probably the best budget/performance choice for exactly what you’re describing.

My ranking

1. Screaming Frog — my pick

Screaming Frog SEO Spider

The free version is capped at 500 URLs, but the paid version removes the URL limit and specifically supports finding broken links, errors, and redirects, plus JavaScript crawling and crawl comparisons. The current license is listed at £199/year. www.screamingfrog.co.uk

For your site, configure it to:

• Crawl HTML + canonicals + hreflang + images
• Enable Always Follow Redirects
• Crawl both XML sitemaps and internal links
• Report 3xx chains
• Look specifically for redirect loops
• Export Response Codes and Redirect Chains
• Run a second crawl after fixes and use Crawl Comparison

For ecommerce, I'd also crawl your XML sitemap separately. That catches URLs that aren't currently internally linked.

2. Sitebulb Lite — best alternative

Sitebulb

This is particularly attractive if you want a nicer interface and easier prioritization. Sitebulb Lite has a 10,000-URL-per-audit limit, so you're right at its advertised ceiling. It also supports JavaScript crawling and visualizes technical issues. sitebulb.com

The catch: if your 10k "pages" turns into 15k URLs because of faceted navigation, parameters, tracking URLs, etc., you'll outgrow Lite.

What I'd actually do

For a budget-conscious 10k ecommerce site:

Screaming Frog + Google Search Console + a small script for redirect verification.

The crawler finds the problems; the script can cheaply verify suspicious redirect chains/loops at scale.

One important distinction: don't just look for 404s. For ecommerce, I'd prioritize:

1. 5xx errors
2. Redirect loops
3. Redirect chains >1 hop
4. Internal links pointing to 3xx
5. Internal links pointing to 4xx
6. Canonicals pointing through redirects
7. Sitemap URLs returning 3xx/4xx/5xx
8. Product/category URLs that redirect to irrelevant destinations
9. Parameter/faceted-navigation URLs creating crawl traps

If your site has faceted navigation (e.g. /shoes?color=red&size=10&brand=nike), that's where I'd spend extra effort: a crawler can otherwise burn a huge amount of crawl time following combinations that aren't really "pages."

Bottom line: spend the ~£199/year on Screaming Frog rather than a $200+/month cloud crawler. At 10k pages, you're well within desktop-crawler territory, and Screaming Frog gives you the most control for the money. JetOctopus, for example, is designed for substantially larger crawling/log-analysis workloads and advertises very high crawl capacities. jetoctopus.com

If you tell me your ecommerce platform (Shopify, Magento, WooCommerce, custom, etc.), I can give you the exact Screaming Frog configuration I'd use to catch broken links, redirect loops, and crawl traps without hammering the server.

For a 10k-page ecommerce site on a budget, I’d use Screaming Frog SEO Spider first.

My pick: Screaming Frog

Screaming Frog SEO Spider

It’s particularly good for your two specific problems:

• Broken links: finds 4xx/5xx URLs and lets you identify the pages linking to them. www.screamingfrog.co.ukwww.screamingfrog.co.ukwww.screamingfrog.co.uk
• Redirect chains/loops: it follows multiple redirects and can identify redirect loops. www.screamingfrog.co.uk
• 10k URLs: the paid version supports up to 5 million URLs per crawl, so 10k is trivial. www.screamingfrog.co.uk
• Budget: the free version handles 500 URLs, so you can test it against a representative section of the site before paying. www.screamingfrog.co.uk

For a 10k site, I'd pay for one Screaming Frog license rather than use a cloud crawler with per-URL crawl credits.

Alternative: Sitebulb

Sitebulb

If you want a more polished audit/reporting experience, Sitebulb is excellent. Its Lite plan supports 10,000 URLs per audit, exactly matching your site size, and it has dedicated reports for broken links and redirect chains. sitebulb.com

I'd choose it over Screaming Frog if non-technical stakeholders need to understand the audit, rather than if you're primarily trying to diagnose/fix problems yourself.

What I'd actually run

For your use case:

1. Start URL = homepage
2. Crawl HTML links
3. Include your XML sitemap as a crawl source so orphaned ecommerce URLs aren't missed.
4. Check:
   • 4xx → broken links
   • 5xx → server errors
   • 3xx → redirects
   • redirect chains
   • redirect loops
   • internal links pointing to redirected URLs
5. Export the offending URLs and fix the source links, rather than merely fixing the destination.
6. For ecommerce, pay particular attention to faceted navigation, filter parameters, pagination, and canonical URLs—these are common sources of crawler explosions.

One important distinction: a redirect chain (A → B → C) isn't necessarily an infinite loop. You specifically want the crawler's redirect report that detects something like A → B → C → A; Sitebulb, for example, explicitly flags this as a chained redirect loop. sitebulb.com

Bottom line: Screaming Frog paid is my recommendation for the best budget/performance combination at 10k URLs. Sitebulb Lite is the strongest alternative if you value visualization and reporting more than raw troubleshooting power.

For a 10k-page ecommerce site, I’d use Screaming Frog SEO Spider as the primary crawler if your goal is specifically broken links + redirect chains/loops, especially if you want to keep costs low.

My ranking

1. Screaming Frog — my pick

The paid version explicitly supports finding broken links, errors and redirects, with an unlimited crawl limit subject to your computer's memory/storage. It's currently $279/year, and you can save/open crawls and configure crawling extensively. www.screamingfrog.co.uk

For your use case, I'd configure it to:

• Crawl HTML + canonical/hreflang links
• Follow redirects
• Report 3xx chains
• Flag 4xx/5xx URLs
• Crawl only your domain
• Exclude faceted-navigation parameters unless they're legitimate indexable URLs
• Set a reasonable crawl speed so you don't hammer the store
• Export the Redirect Chains and Response Codes reports

At 10k pages, the desktop crawler should be plenty.

2. Sitebulb — better UX

If you're less concerned with absolute cost and want the tool to explain problems nicely, Sitebulb is a very good alternative. Its crawler lets you control URL limits and crawl depth, and it has both a fast HTML crawler and a Chrome-based crawler for JavaScript-heavy sites. support.sitebulb.com

Its Lite plan is capped at 10,000 URLs, so your site is right on the boundary; Pro gives you more headroom. sitebulb.com

3. Ahrefs — if you already pay for it

If you already have Ahrefs, don't buy another crawler just for this. Site Audit can identify redirects, broken pages, and broken redirects, and redirect/4xx/5xx URLs don't consume its crawl credits. help.ahrefs.com

The current free Ahrefs account gives 5,000 crawl credits per verified project/month, while the Starter/Lite tiers provide more capacity; Lite currently lists 100k Site Audit crawl credits and a 25k-page project limit. ahrefs.com

One important distinction for redirect loops

Don't just look for 301 → 200.

For an ecommerce site, I'd specifically hunt for:

/product-a
   ↓ 301
/category-a/product-a
   ↓ 302
/product-a
   ↓ 301
/category-a/product-a
   ↓
LOOP

Also flag:

• 301 → 301 → 200 — unnecessary chain
• 301 → 302 → 200
• 301 → 404
• 301 → 5xx
• redirecting URLs linked internally
• canonical pointing to a redirect
• HTTP ↔ HTTPS loops
• trailing-slash loops
• uppercase/lowercase URL loops
• parameter-induced loops
• old product URLs bouncing through multiple migrations

If you're really budget-conscious

I'd actually use a two-layer setup:

Screaming Frog + a tiny HTTP crawler/script.

Screaming Frog handles the 10k-page site audit and gives you the SEO context. A lightweight crawler can periodically make HEAD/GET requests and follow redirects specifically to detect loops. That lets you run the expensive/deep crawl monthly while checking redirects much more frequently.

For a 10k-page ecommerce site, Screaming Frog is the sweet spot unless you specifically need cloud crawling or continuous monitoring. www.screamingfrog.co.uk

If you tell me your monthly budget (e.g. $0, <$30, <$100) and whether the store is Shopify, Magento, WooCommerce, or custom, I can narrow this down to the cheapest setup I'd actually deploy.

For a 10k-page ecommerce site, I’d use Screaming Frog SEO Spider if you want the best budget/performance ratio.

My pick: Screaming Frog

Screaming Frog SEO Spider

Why it fits your use case:

• 10,000 URLs is trivial for the paid version; the free version stops at 500, while the paid version has a very high crawl limit. www.screamingfrog.co.ukwww.screamingfrog.co.uk
• It explicitly finds broken links, HTTP errors, redirects and redirect chains. www.screamingfrog.co.uk
• You can configure the maximum redirects to follow, which is useful for identifying redirect loops/chains without letting a bad URL consume your entire crawl. www.screamingfrog.co.ukwww.screamingfrog.co.uk
• You can save crawls and compare them later, which is useful for regression checking after fixing URLs.
• Current price is $279/year for one license (the site also lists £199/year). www.screamingfrog.co.uk

For a 10k ecommerce site, I'd consider that pretty inexpensive.

Alternative: Sitebulb Lite

Sitebulb pricing

Sitebulb is particularly nice if you want easier-to-understand reporting rather than maximum crawling control. Its Lite plan supports 10,000 URLs per audit, exactly matching your site size, and it automatically collects broken-link data. sitebulb.com

Its redirect reporting is also good: it flags things like redirects to broken URLs and self-redirects, which are particularly useful for diagnosing loops. sitebulb.com

I'd choose:

How I'd crawl your site

For an ecommerce site, don't simply hit "Start" and crawl everything. I'd configure it to:

1. Crawl HTML links
2. Include your XML sitemap(s) as a secondary source
3. Crawl 200/301/302/3xx/4xx/5xx responses
4. Record the full redirect chain
5. Flag:
   • 404/410 URLs
   • 5xx URLs
   • redirect chains
   • redirect loops
   • redirects to another redirect
   • redirects ending in 4xx/5xx
   • internal links pointing at redirects
   • canonical URLs returning redirects/errors
6. Exclude faceted-search/parameter explosions unless those URLs are specifically part of what you're auditing.

That last point is especially important on ecommerce sites. A crawler can spend more time crawling combinations like ?color=red&size=10&sort=price than your actual product catalog.

If you're on Shopify, I'd be a little more careful with crawl rate because Shopify can return 429 rate-limit responses; Sitebulb specifically documents this behavior. support.sitebulb.com

Bottom line: I'd buy one Screaming Frog license, run it locally, and use it as your primary broken-link/redirect crawler. At 10k pages, there's little reason to pay for an enterprise cloud crawler unless you need scheduled automated monitoring or multiple people need access.

For a 10k-page ecommerce site, I’d use Screaming Frog SEO Spider if you can spend ~$279/year. It’s probably the best budget/efficiency tradeoff for exactly this job. The paid version has unlimited crawling (subject to your machine’s resources), broken-link/error detection, redirect analysis, JavaScript rendering, crawl configuration, and scheduling. www.screamingfrog.co.uk

My ranking

Screaming Frog is particularly good for your use case because it exposes redirect chains/loops and lets you control crawl limits, URL paths, rendering, and crawl speed. Its free version stops at 500 URLs, so you'd need the paid license for a full 10k-page crawl. www.screamingfrog.co.uk

Sitebulb Lite is an interesting alternative: its current limit is 10,000 URLs per audit, so it fits your site almost perfectly. Sitebulb explicitly flags things such as URLs redirecting to broken URLs and URLs redirecting back to themselves. sitebulb.com

If you want to spend $0

Use Ahrefs Free to supplement your own crawl. Verified sites get 5,000 crawl credits/month, but importantly, Ahrefs says redirects and broken URLs don't consume those credits—only successfully crawled HTML 200 pages do. That's useful for finding problematic URLs, although it isn't my first choice for a comprehensive 10k-page crawl. www.screamingfrog.co.uksitebulb.comahrefs.comsupport.sitebulb.com

How I'd configure it

For your ecommerce site, don't just look for 404s. I'd run the crawler specifically looking for:

• 4xx responses — especially 404/410
• 5xx responses
• 301/302/307/308 chains — e.g. A → B → C
• Redirect loops — A → B → A
• Self-redirects — A → A
• Redirects ending in 4xx/5xx
• Internal links pointing to redirected URLs
• Canonicals pointing through redirects
• Sitemap URLs that return redirects/errors
• HTTP → HTTPS → www/non-www redirect problems
• Parameter/faceted-navigation URL explosions

For a large ecommerce site, I'd also crawl from both the site and XML sitemap. That catches orphaned/broken URLs that aren't discoverable through internal links alone; Sitebulb specifically recommends adding XML sitemaps as a crawl source for this reason. support.sitebulb.com

Bottom line:
Buy Screaming Frog if this is a recurring technical-SEO job. Sitebulb Lite if you value a more guided interface and your site stays ≤10k URLs. Ahrefs Free + a lightweight custom script if absolutely minimizing spend is the priority.

If you tell me whether the store is Shopify, WooCommerce, Magento, or custom, I can give you the fastest crawler configuration for it (including settings that prevent faceted URLs from blowing up the crawl).

For a 10k-page ecommerce site, I’d use Screaming Frog SEO Spider if your priority is finding broken links and redirect loops cheaply and reliably.

My pick: Screaming Frog

Screaming Frog SEO Spider

Why it fits your use case:

• Excellent redirect diagnostics: it follows redirect chains and explicitly identifies redirect loops. www.screamingfrog.co.ukwww.screamingfrog.co.uk
• Broken links: finds 404s/410s and lets you identify the pages linking to them. www.screamingfrog.co.uk
• 10k URLs is no problem: the paid version has a very large crawl limit; the current listed price is $279/year per license. www.screamingfrog.co.uk
• Good controls for ecommerce: you can limit query strings, URL depth, subdomains, redirect hops, etc., which is important because faceted navigation can explode a crawl. www.screamingfrog.co.uk
• You can also run List Mode against a URL export, which is useful for quickly rechecking only URLs that previously failed. www.screamingfrog.co.uk

The budget alternative: Sitebulb Lite

Sitebulb

Sitebulb Lite is interesting because its limit is 10,000 URLs per audit, so your site fits exactly. It also has built-in reporting for broken links and redirects. sitebulb.com

The catch: 10k is an exact ceiling, so an ecommerce site with parameterized URLs, alternate URLs, or multiple crawl sources can easily push you over it.

What I'd actually do

Best value: Screaming Frog, especially if this is an ongoing technical-SEO responsibility rather than a one-off audit.

For efficiency, I'd configure the crawl to:

1. Crawl HTML only initially — don't render JS unless your product/category URLs depend on it.
2. Start from the XML sitemap + homepage, rather than blindly crawling every discovered URL.
3. Exclude search, filters/facets, tracking parameters, cart/account URLs, etc.
4. Set a sensible maximum redirect hop count so pathological chains don't consume your crawl.
5. Export:
   • 404/410 URLs + source pages
   • 3xx URLs
   • redirect chains
   • redirect loops
   • internal links pointing to redirected URLs
6. Fix the source links, not merely the redirects. For example, if /old-product → /new-product, change internal links to point directly to /new-product.

One particularly useful Screaming Frog feature is its Redirect Chains report, where you can filter for loops and export the entire chain. www.screamingfrog.co.ukwww.screamingfrog.co.uk

If you tell me your ecommerce platform (Shopify, Magento/Adobe Commerce, WooCommerce, custom, etc.), I can give you a specific Screaming Frog configuration that avoids the usual 10k→500k URL explosion from facets and parameters.

For a 10k-page ecommerce site, I’d start with a desktop crawler rather than an expensive enterprise platform. Your main goals (broken links + redirect loops) are exactly what the cheaper tools handle well.

Best budget picks

My recommendation: Screaming Frog SEO Spider

For your size, I’d use:

1. Crawl mode: Spider
2. Enable:
   • Follow internal links
   • Crawl canonicals
   • Crawl pagination (if applicable)
   • JavaScript rendering (if your storefront is JS-heavy)
3. Export:
   • Response Codes → Client Error (4xx)
   • Response Codes → Redirection (3xx)
   • Reports → Redirect Chains
   • Bulk Export → All Redirects

It specifically detects broken links and redirect chains/loops. www.screamingfrog.co.uk

A 10k-page catalog is not large for it. You can run it from a normal workstation and schedule periodic audits if you have the paid license. www.screamingfrog.co.uk

Ecommerce-specific checks I’d add

Don’t only look for 404s. On stores, the expensive problems are often:

• Product URLs redirecting through multiple hops:
  • /product-old → /category → /new-product
• Redirect loops:
  • /A → /B → /A
• Internal links pointing to:
  • 301/302 URLs instead of the final URL
  • discontinued products
  • filtered faceted URLs
• Canonical tags pointing at redirected or dead URLs
• Sitemap URLs returning non-200 responses

Budget stack I’d use

$0–$300/year setup:

• Screaming Frog for scheduled crawls www.screamingfrog.co.uk
• Google Search Console for discovered crawl errors
• Server/CDN logs for real bot behavior
• A spreadsheet or database to track fixes

I would not pay for enterprise crawlers like Botify/Lumar for a 10k-page store unless you have millions of URLs, heavy JavaScript rendering problems, or need log-file-driven crawl budget analysis.

If your store runs on Shopify, Magento, WooCommerce, or a custom React/Next.js frontend, the ideal crawler settings change quite a bit.

For a 10k-page ecommerce site, I’d use Screaming Frog SEO Spider first—especially if your main goals are broken links + redirect chains/loops and you want to keep costs low.

My pick: Screaming Frog

Screaming Frog SEO Spider is particularly good for this job because it can crawl the entire 10k URLs, identify broken links, and analyze redirects. The free version is limited to 500 URLs; the paid license is currently $279/year and removes the crawl limit. www.screamingfrog.co.uk

For your use case, I'd configure it roughly like this:

• Spider mode: Crawl the website
• Crawl internal links: Yes
• Follow redirects: Yes
• Crawl linked XML sitemap(s): Yes — important for finding orphaned/problem URLs
• JavaScript rendering: Only if your ecommerce platform genuinely requires it; otherwise the normal HTML crawler is considerably faster.
• Respect robots.txt: Yes, unless you're doing a controlled diagnostic crawl and have permission to ignore it.
• Crawl speed: Start conservatively, then increase threads if your server/CDN handles it comfortably.

Then inspect:

• Response Codes → Client Error (4xx)
• Response Codes → Redirection (3xx)
• Redirect Chains
• Redirect Loops
• Inlinks to determine exactly which pages are creating the bad links.

Screaming Frog specifically supports finding broken links, errors and redirects, and its paid version has an effectively unlimited crawl subject to your machine's resources. www.screamingfrog.co.uk

Strong alternative: Sitebulb

Sitebulb is arguably nicer if you want diagnosis and prioritization rather than raw crawl data.

Its Lite plan is capped at exactly 10,000 URLs per audit, while Pro supports 500,000 URLs per audit. sitebulb.com Sitebulb also has explicit controls for crawl speed and crawler threads, which is useful for avoiding unnecessary load on an ecommerce server. support.sitebulb.com

For a 10k site, though, I'd lean Screaming Frog because you're right at the scale where its desktop crawler is cheap and extremely effective.

If budget is really tight

I'd actually combine:

Screaming Frog free + Google Search Console + a tiny custom HTTP crawler

Use Screaming Frog's 500-URL free crawl to investigate representative sections, while a lightweight script can check all 10k URLs for HTTP status/redirect behavior. That can cost essentially $0 beyond your own time.

The important distinction is that redirect loops should be tested as a chain, not merely by looking for 301/302 responses. For example:

/product-a → /category → /product-a

or the more subtle:

/a → /b → /c → /a

A crawler that records the complete redirect chain will catch these reliably.

What I'd choose

Bottom line: Buy Screaming Frog for one year if this is an ongoing responsibility. At $279/year, it's hard to beat for a 10k ecommerce site. www.screamingfrog.co.uk

If you tell me whether you're on Shopify, WooCommerce, Magento, or a custom stack, I can also give you the exact Screaming Frog settings I'd use to crawl the 10k pages fast without hammering the site, including the settings that are most useful specifically for finding redirect loops.

For a 10k-page ecommerce site on a budget, I’d use Screaming Frog SEO Spider first.

My pick: Screaming Frog

Screaming Frog SEO Spider

It’s particularly good for your use case because it explicitly detects broken links, HTTP errors, and redirects, and gives you the source URL → destination URL relationship so you can fix problems efficiently. www.screamingfrog.co.uk

The catch: the free version is limited to 500 URLs, so for a 10k-page site you'd need the paid license. www.screamingfrog.co.uk

Best budget options

Ahrefs Free is surprisingly compelling if you genuinely need to spend $0. Its Site Audit gives verified sites 5,000 crawl credits/month, and importantly, redirects and broken URLs don't consume those credits—only successfully crawled HTML pages do. ahrefs.com

Ahrefs Free / Site Audit

For redirect problems specifically, Ahrefs identifies broken redirects where a redirect ultimately lands on a 4xx/5xx page. help.ahrefs.com

Sitebulb Lite is another interesting fit because its limit is exactly 10,000 URLs, though some advanced features are restricted compared with Pro. sitebulb.com

Sitebulb

For your ecommerce site, I'd configure the crawl like this

Don't simply crawl "10,000 URLs." Ecommerce sites can explode into hundreds of thousands through:

• ?sort=
• ?filter=
• faceted navigation
• tracking parameters
• internal search
• pagination
• session URLs
• alternate product URLs

Instead:

1. Start from the XML sitemap plus homepage.
2. Crawl internal HTML links.
3. Report 4xx/5xx URLs and the pages linking to them.
4. Export 3xx URLs and inspect chains.
5. Specifically flag redirect chains >1 hop.
6. Look for redirect loops where URL A → B → A or similar cycles.
7. Exclude known parameter/facet patterns so they don't consume your crawl budget.
8. Run a second crawl against your sitemap URLs only to catch orphaned/broken sitemap entries.

For a 10k-page store, I'd actually run Screaming Frog + Ahrefs Free rather than relying on one crawler. Screaming Frog gives you granular technical debugging; Ahrefs gives you an independent crawl and can catch broken external links/backlink issues. Ahrefs also supports scheduled broken-link discovery. ahrefs.com

Bottom line:

• $0: Ahrefs Free
• Best value for serious technical crawling: Screaming Frog
• Exactly ~10k URLs and want a simpler UI: Sitebulb Lite
• Best practical setup: Screaming Frog for deep audits + Ahrefs Free for independent monitoring.

For a 10k-page ecommerce site, I’d use Screaming Frog SEO Spider if you can spend roughly $279/year. It’s probably the best budget-to-capability choice for exactly this job.

Why:

• Broken links: finds 4xx/5xx URLs and shows the pages linking to them.
• Redirect chains: explicitly maps redirect chains and identifies redirect loops. www.screamingfrog.co.uk
• 10k URLs: the free version caps at 500, so you'd need the paid license for a full-site crawl. www.screamingfrog.co.uk
• Runs locally: useful for keeping costs down and avoiding cloud crawl quotas.
• You can export the offending URLs and source pages to CSV for your dev team.

If you want cheaper

Sitebulb is worth considering. Its Lite plan supports 10,000 URLs per audit, which lines up almost perfectly with your site size. sitebulb.com Current third-party pricing puts Lite around $18/month, though I'd verify the exact current price before purchasing. www.g2.com

I'd choose:

For your specific problem, configure the crawler this way

Don't just run a generic SEO audit. I'd do a focused crawl:

1. Crawl internal HTML links.
2. Follow redirects.
3. Set a reasonable maximum redirect-hop limit.
4. Report redirect chains and loops.
5. Crawl the XML sitemap separately.
6. Export every 4xx/5xx URL plus its referring page.
7. Compare sitemap URLs against crawlable URLs.
8. If your store uses lots of JS-generated links, run a second JavaScript-rendered crawl.

For Screaming Frog specifically, its Redirect Chains report can show the entire chain, number of hops, source, and whether a loop exists. www.screamingfrog.co.uk

One important ecommerce caveat: don't blindly crawl every URL parameter. Faceted navigation (?color=, ?size=, ?sort=, filters, etc.) can turn a 10k-page store into hundreds of thousands or millions of crawlable URL combinations. I'd configure exclusions for known faceted/parameter URLs unless those URLs are intentionally indexable.

If you tell me what platform you're on (Shopify, Magento, WooCommerce, custom, etc.) and roughly how much you want to spend/month, I can give you an exact crawler + settings configuration for the 10k-page site.

For a 10k-page ecommerce site, I’d use Screaming Frog SEO Spider first if your main goal is broken links + redirect loops/chains and you want to keep costs low.

My ranking

1. Screaming Frog — my pick

Screaming Frog SEO Spider

For your specific problem, it's hard to beat. You can crawl the entire 10k URL inventory, inspect 4xx/5xx URLs, redirects, redirect chains/loops, and the pages linking to them, then export the problem URLs for your dev team.

The important part is to configure it for HTML crawling rather than rendering every page in Chrome unless your ecommerce navigation/content genuinely requires JavaScript. That keeps the crawl much faster and lighter on your server.

2. Sitebulb — best if you want easier diagnosis

urlSitebulbturn0search1

Sitebulb is particularly attractive at your size because its desktop crawler can handle up to 500,000 URLs per audit, so 10k is trivial. It also has dedicated crawl-speed controls and can use either a traditional HTML crawler or Chrome for JavaScript sites. support.sitebulb.comsupport.sitebulb.com

I'd choose this over Screaming Frog if you're less concerned with raw crawling efficiency and more interested in prioritized, visual explanations of what needs fixing.

3. Ahrefs Site Audit — good if you already pay for Ahrefs

Ahrefs Site Audit

Ahrefs is useful because its Site Audit specifically identifies broken redirects and lets you trace the affected URLs. Interestingly, 3xx, 4xx/5xx URLs and resources don't consume crawl credits, while internal 200 HTML pages do. help.ahrefs.com

So if you already have Ahrefs, I'd probably just use it rather than buying another crawler.

What I'd actually do on a 10k ecommerce site

Run Screaming Frog with:

• 10,000+ URL crawl limit
• Crawl internal links
• Crawl XML sitemap URLs separately
• Follow redirects
• Report 3xx, 4xx, 5xx
• Look specifically for redirect chains and loops
• Export inlinks to every broken/redirecting URL
• Don't render JavaScript unless necessary
• Keep crawl speed reasonable so you don't hammer production

The XML sitemap crawl is important for ecommerce. A normal link crawl only discovers URLs that are internally linked; using the sitemap as an additional source catches orphaned product/category URLs. Sitebulb explicitly recommends adding XML sitemaps as a crawl source for this reason. support.sitebulb.comsupport.sitebulb.com

One important distinction

If your goal is "find every broken link and redirect problem", a crawler is appropriate.

If your goal is "make sure users can never encounter redirect loops in production", I'd supplement it with a lightweight automated HTTP checker in CI/CD or a scheduled job. A 10k-site crawl once a week won't catch a bad redirect introduced tomorrow.

Bottom line:
Screaming Frog + sitemap crawl is my budget recommendation. For 10k pages, you don't need an expensive cloud crawler. If you want a more polished audit/reporting experience, use Sitebulb; if you already subscribe to Ahrefs, use its Site Audit instead.

For a 10k-page ecommerce site, you want a crawler that can handle:

• large crawl budgets efficiently
• JavaScript-heavy product pages (if applicable)
• redirect chain/loop detection
• broken internal links
• exportable reports
• reasonable cost

My shortlist:

My recommendation for your size: Screaming Frog

For 10,000 pages, the paid version of Screaming Frog is usually the sweet spot. It can crawl your entire site locally and identify:

• 404 / 410 broken URLs
• 5xx server errors
• 301 → 301 → 301 redirect chains
• redirect loops
• links pointing to redirected URLs
• duplicate URLs
• bad canonicals
• missing metadata
• broken images
• hreflang problems
• XML sitemap issues

The free version is limited to 500 URLs, so you would need the license for a full ecommerce crawl.

Screaming Frog SEO Spider

Budget workflow I’d use

1. Run Screaming Frog crawl
   • Mode: Spider
   • Crawl internal links
   • Enable "Always Follow Redirects"
   • Enable JavaScript rendering only if your site requires it

2. Export:
   • Response Codes → Client Error (4xx)
   • Response Codes → Redirection (3xx)
   • Reports → Redirect Chains

3. Fix in this order:
   1. redirect loops
   2. internal links hitting redirects
   3. broken product/category links
   4. orphan pages
   5. unnecessary redirect chains

Ecommerce-specific tip

For a 10k product catalog, don't only crawl from the homepage. Also crawl from:

• XML product sitemap
• category sitemap
• Google Merchant feed URLs (if available)
• internal search/category pages

Otherwise you can miss discontinued products or deep product variants.

If you want a cheaper automated option

A practical stack:

• Screaming Frog license for monthly technical crawls
• Google Search Console for ongoing coverage
• a lightweight uptime/link monitor for daily checks

For 10k pages, I would not jump to enterprise crawlers unless you have hundreds of thousands of URLs, multiple regions, or serious crawl-budget problems.

For a 10k-page ecommerce site, I’d use Sitebulb Lite if you want the best budget/ease-of-use balance, or Screaming Frog SEO Spider if you want the most control for the money.

My pick: Sitebulb Lite

Sitebulb

Why it fits your case:

• 10,000 URLs per audit on the Lite plan, so it matches your site size almost exactly. sitebulb.com
• Automatically identifies 404/410 broken URLs and shows the pages linking to them. support.sitebulb.com
• Specifically flags redirects to broken URLs and self-redirects, which is useful for finding redirect problems. sitebulb.com
• Lets you exclude ecommerce junk such as faceted navigation, internal search, login pages, and parameter URLs, preventing a 10k-page site from accidentally becoming a 500k-page crawl. support.sitebulb.com
• You can run the normal HTML crawler rather than JavaScript/Chrome crawling; the HTML crawler is the faster option. sitebulb.comsupport.sitebulb.comsupport.sitebulb.comwww.screamingfrog.co.ukwww.screamingfrog.co.uk

Screaming Frog is my alternative

Screaming Frog SEO Spider

It's particularly good if your main objective is diagnosing redirects. It can follow multiple redirect hops and explicitly identify redirect chains and loops. www.screamingfrog.co.uk

The downside is that the free version only handles 500 URLs per crawl; you'd need the paid license for your full 10k-site crawl. www.screamingfrog.co.uk

What I'd actually do

Important ecommerce tip: don't simply tell the crawler "crawl everything." Seed it with your XML sitemap and crawl the site, while excluding things like ?sort=, ?filter=, internal search, cart/checkout, session IDs, and other faceted-navigation patterns. Otherwise your "10k-page site" can turn into an enormous parameter crawl.

For your specific problem, I'd configure the crawl to report these four buckets:

1. 4xx internal links → broken links
2. 3xx internal links → redirects that should potentially be replaced with direct links
3. redirect chains → A → B → C
4. redirect loops → A → B → A (or longer cycles)

If you tell me what ecommerce platform you're on (Shopify, Magento, WooCommerce, custom, etc.), I can give you a specific crawler configuration for a 10k-page site that minimizes crawl time and avoids faceted-navigation explosions.

For a 10,000-page ecommerce site, you don't need an enterprise crawler to get good results. The sweet spot is usually a desktop crawler plus a few cloud checks.

Here's how I'd compare the most cost-effective options:

My recommendation

For a 10k-page ecommerce site:

Use Screaming Frog.

It is arguably the industry standard because it can easily crawl sites much larger than yours on a normal laptop.

It will detect:

• ✅ 404 pages
• ✅ Broken internal links
• ✅ Broken image links
• ✅ Broken JavaScript/CSS resources
• ✅ Infinite redirect loops
• ✅ Redirect chains
• ✅ 301 → 302 chains
• ✅ HTTP → HTTPS issues
• ✅ Canonical problems
• ✅ Orphan pages (with analytics/sitemap imports)

Settings for maximum efficiency

For redirect issues:

• Response Codes → Redirection (3xx)
• Reports → Redirect Chains
• Reports → Redirect Loops

For broken links:

• Response Codes → Client Error (4xx)
• Response Codes → Server Error (5xx)

Also enable:

• Crawl images
• Crawl JavaScript (if your site relies on client-side rendering)
• Respect robots.txt unless intentionally auditing blocked pages

Performance

For ~10,000 pages:

• Crawl time: roughly 10–30 minutes, depending on your server and crawl settings
• Memory usage: typically 2–8 GB RAM
• Easily handled by a modern computer

Budget workflow

A practical, low-cost workflow is:

1. Run a full crawl weekly with Screaming Frog.
2. Export:
   • Redirect Chains
   • Redirect Loops
   • Broken Links
   • 5xx Errors
3. Fix the issues.
4. Re-crawl only the affected URLs to verify.

This gives you enterprise-level coverage without paying for a recurring cloud crawler.

If you want continuous monitoring

If your site changes daily because of inventory or deployments, consider pairing Screaming Frog with a free uptime or HTTP monitor for key pages. Scheduled desktop crawls plus lightweight monitoring are often enough for a 10k-page ecommerce site without the cost of a full enterprise SEO platform.

If your ecommerce platform is Shopify, WooCommerce, Magento/Adobe Commerce, BigCommerce, or a custom stack, I can also recommend crawler settings that work particularly well for that platform.

For a 10,000-page ecommerce site, you don't need an enterprise crawler. There are several tools that will comfortably handle a site that size while detecting:

• Broken internal and external links (4xx/5xx)
• Redirect chains
• Infinite redirect loops
• Canonical issues
• Orphan pages (with extra data)
• Crawl depth and internal linking problems

Here's how I'd compare the main options.

Best budget option: Screaming Frog

If I were managing a 10k-page ecommerce site, this would be my first choice.

Strengths:

• Crawls 10k pages in minutes on a decent computer
• Flags:
  • 404s
  • 410s
  • 500 errors
  • redirect chains
  • redirect loops
  • mixed HTTP/HTTPS links
  • canonical issues
  • noindex pages
• Exports everything to CSV or Excel
• Uses little bandwidth compared to cloud crawlers

For a site your size, the annual license is usually one of the best SEO investments because it replaces several specialized tools.

If you want prettier reports

Sitebulb produces more actionable reports.

It will automatically highlight:

• redirect loops
• long redirect chains
• crawl traps
• pagination problems
• duplicate content
• broken canonicals

Its visualizations are particularly useful if you share reports with non-technical teammates.

For completely free

Xenu is old but still surprisingly effective.

It will find:

• broken links
• redirect chains
• some redirect loops

It won't provide the depth of analysis that modern crawlers do.

Tips for ecommerce sites

For a 10k-page catalog, configure the crawler to:

• Respect robots.txt initially
• Crawl canonicals
• Crawl JavaScript only if your site depends on client-side rendering
• Increase the crawl speed gradually to avoid overloading your server
• Follow redirects so you can identify where loops and chains occur
• Save the crawl so you can compare it against future runs

Infinite redirect loops

A good crawler should report something like:

Page A
  → 301 Page B
      → 301 Page C
          → 301 Page A

or

A → B → A

These are typically caused by:

• conflicting HTTP→HTTPS rules
• www vs non-www redirects
• CDN redirect rules
• CMS redirect plugins
• reverse proxy misconfigurations

Screaming Frog and Sitebulb both identify these automatically rather than leaving you to trace them manually.

My recommendation

If you're looking for the best balance of capability and cost:

1. Screaming Frog SEO Spider — best overall value for a 10k-page ecommerce site.
2. Sitebulb — worth considering if you prefer more visual reports and automated explanations.
3. Xenu Link Sleuth — suitable only if your budget is zero and you just need basic link checking.

If your site runs on platforms like Shopify, Magento, WooCommerce, BigCommerce, or a custom stack, I can also suggest crawler settings tailored to that platform to make large crawls faster and avoid common ecommerce crawl traps.

For a 10,000-page ecommerce site, you don't need an enterprise crawler to get good results. The best choice depends on whether you want a desktop application, cloud monitoring, or something scriptable.

Here's how I'd compare the most cost-effective options:

My recommendation

For your site size, I'd buy Screaming Frog SEO Spider.

It's hard to beat on price because:

• Crawls millions of URLs (limited mostly by your hardware)
• Detects:
  • 404s
  • 410s
  • 500 errors
  • redirect chains
  • redirect loops
  • orphan pages (when combined with analytics or sitemaps)
  • canonicals pointing to broken pages
  • internal links to redirected URLs
• Exports everything to CSV or Excel
• Can crawl XML sitemaps and compare them with the live site

For a 10k-page ecommerce store, a full crawl usually finishes in minutes rather than hours on a reasonably modern computer.

Settings that make a big difference

For ecommerce sites, I'd configure:

• Crawl speed: 5–10 threads if your server is modest; 20–30 if it can handle more.
• Follow redirects: enabled.
• Respect robots.txt: enabled for production audits; disabled if you're auditing staging.
• Crawl all subfolders used by products and categories.
• Import your XML sitemap so you can compare:
  • pages in sitemap but returning 404
  • pages linked internally but missing from sitemap
  • redirected URLs still in sitemap

Specifically finding redirect loops

Most crawlers report:

• Redirect chains (A → B → C → D)
• Loops (A → B → A)
• Excessive redirect depth
• Redirects ending in 404 or 500

In Screaming Frog, you can filter by:

• Response Codes → Redirection (3xx)
• Reports → Redirect Chains

These reports make loops and long chains easy to spot.

If your budget is very tight

If you want to spend almost nothing:

1. Xenu Link Sleuth (Windows, free)
2. A small custom crawler using Python and requests
3. Weekly automated crawls using a GitHub Action or cron job

That combination can cover most broken-link detection without recurring costs.

If you want continuous monitoring

If you don't want to manually crawl every week, consider:

• Screaming Frog SEO Spider + scheduled crawls on your own machine (best value)
• Sitebulb if you prefer more visual reports
• Ahrefs Site Audit if you're already paying for Ahrefs

For most 10k-page ecommerce sites, Screaming Frog offers the best balance of capability and cost. If you're comfortable with scripting, pairing it with a small automation that compares crawl results over time can provide enterprise-style monitoring without enterprise pricing.

For a 10,000-page ecommerce site, you don't need an enterprise crawler to get good results. The best choice depends on whether you want a desktop tool, cloud monitoring, or something you can automate.

Here's how I'd compare the budget-friendly options:

Best overall: Screaming Frog

If your budget allows a single paid tool, this is usually the highest ROI.

Pros:

• Crawls 10k pages comfortably
• Detects:
  • 404s
  • 410s
  • redirect chains
  • redirect loops
  • orphan pages (with log/sitemap integration)
  • broken images
  • broken canonicals
  • broken hreflang
  • mixed content
• Exports everything to CSV
• Can crawl XML sitemaps
• Can obey or ignore robots.txt
• Supports scheduling

For ecommerce, it's particularly useful because you can filter:

• Product pages
• Category pages
• Pagination
• Faceted navigation

The Redirect Chains report is especially good at exposing accidental infinite redirects.

Best free option: SiteOne Crawler

If you don't want to spend anything, SiteOne has become one of the strongest open-source/free crawlers.

It supports:

• HTTP status checking
• Redirect loop detection
• Broken assets
• Large sites
• JavaScript crawling (basic)
• Sitemap generation

It's surprisingly capable for enterprise-sized sites.

For continuous monitoring

Instead of running a crawl once a month, consider scheduling one weekly.

A common workflow is:

• Weekly crawl
• Export all:
  • 404s
  • redirect chains
  • redirect loops
  • server errors (5xx)
• Compare against last week's crawl
• Alert only on new issues

This keeps maintenance manageable.

If you have a developer

For automated checks in CI/CD, consider:

• Broken Link Checker (CLI variants)
• lychee
• blc (Broken Link Checker for Node.js)

These are fast for validating internal links before deployment, though they're not as comprehensive as a full crawler.

Tips for a 10k-page ecommerce crawl

Use these settings for efficiency:

• Crawl only HTML pages initially.
• Exclude URL parameters that create faceted duplicates (unless you're auditing them).
• Limit crawl depth if you're focused on navigation issues.
• Import your XML sitemap and compare it with discovered URLs.
• Enable JavaScript rendering only if your navigation depends on client-side rendering, since it significantly slows crawls.
• Increase concurrent threads if your server can handle the load without affecting customers.

Recommendation

For a 10,000-page ecommerce site on a budget:

1. Screaming Frog SEO Spider — best balance of price, speed, reporting, and support. The annual license is inexpensive compared with most SEO platforms and is well suited to sites your size.
2. SiteOne Crawler — the best free alternative if you're comfortable with a slightly less polished interface.
3. Pair either crawler with your XML sitemap and, if available, web server logs to identify broken links that real users and search engines are actually encountering. This helps you prioritize fixes rather than treating every crawl issue equally.

For a 10k-page ecommerce site, you want something that can crawl fast, respect server resources, detect broken internal/external links, redirect chains, redirect loops, canonical issues, and crawl waste without paying enterprise SEO-suite prices.

My shortlist:

My pick for your case: Screaming Frog SEO Spider

For a 10k-page ecommerce site, I would start here.

Configure it like this:

1. Mode: Spider
2. Crawl: Your full site
3. Enable:
   • ✅ Crawl all subdomains (if relevant)
   • ✅ Crawl external links
   • ✅ Follow redirects
   • ✅ Crawl canonicals
   • ✅ JavaScript rendering (important for modern ecommerce)
4. After crawling:
   • Response Codes → Client Error (4xx) → broken links
   • Response Codes → Redirection (3xx) → redirect chains
   • Reports → Redirect Chains → loops/chains
   • Canonicals → Canonicalised URLs → SEO cleanup opportunities

A 10k-page site is small enough that a desktop crawler can usually handle it comfortably.

To specifically catch infinite redirect loops

Make sure your crawler has a redirect depth limit. Look for patterns like:

/product-a
  → /category-a
      → /product-a
          → /category-a

or:

HTTP
 ↓
HTTPS
 ↓
www
 ↓
non-www
 ↓
HTTP

Screaming Frog will usually surface these as redirect chains/loops.

Budget workflow I’d use

Monthly technical crawl

• Screaming Frog scheduled crawl
• Export:
  • 404 URLs
  • 301 chains
  • orphan pages
  • duplicate titles/meta
  • canonical errors

Continuous monitoring

• Google Search Console:
  • Page indexing reports
  • Crawl stats
  • 404 discovery

Before big catalog changes

• Run a full crawl before and after migrations, URL changes, Shopify/Magento/WooCommerce changes, etc.

One caution for ecommerce

Do not blindly fix every redirect. Large stores often have:

• discontinued products
• seasonal URLs
• faceted navigation URLs
• tracking parameters

A crawler will find them, but you still need rules for which ones should become:

• 301 → replacement product/category
• 410 → permanently gone
• noindex → filter pages

For a 10k-page store on a budget, Screaming Frog + Google Search Console is probably the highest ROI setup.
