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.

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.
