ChatGPT answers, unedited

For a small ecommerce store on a tight budget, I’d start with Ahrefs—specifically its free tier, then upgrade only if you hit its limits.

My picks

• 🥇 Ahrefs — best overall value

• Its free account gives you Site Explorer for your own verified site, plus organic keyword and backlink data.
• Ahrefs says its paid competitor analysis can show the keywords competitors rank for, estimated organic traffic, and backlinks. Its current Starter plan is aimed at beginners who want to “spy on competitors.” Ahrefs Ahrefs Help Center
• ahrefs.com
• 🥈 Similarweb — best for traffic sources

• Particularly useful when you want to know whether a competitor's traffic comes from search, direct, referrals, social, etc.
• Its free Website Traffic Checker lets you inspect competitor traffic, traffic sources, top keywords, referring domains and more, although the free interface has usage limits. Similarweb
• similarweb.com
• 🥉 Semrush — best if you're serious about SEO/ads

• Very strong for competitor keywords, paid search, backlinks and traffic trends, but it's harder to justify on a very small budget. Semrush's current SEO plan starts substantially higher than Ahrefs Starter. Semrush Semrush
• It does offer a free Competitor Finder that identifies sites sharing your keywords and estimates their organic traffic. Semrush
• semrush.com

What I'd actually do

$0/month: Use Ahrefs Free + Similarweb free. Find 5–10 competitors, then record:

1. Their highest-traffic organic keywords
2. Pages receiving the most organic traffic
3. Keywords where they rank but you don't
4. Their major referral sources
5. Whether they're getting meaningful traffic from social, paid search, or referrals
6. Sites linking to their best-performing pages

That combination gives you surprisingly good competitive intelligence without immediately paying for an expensive all-in-one platform.

If you can spend ~$20–30/month: Ahrefs Starter is the first upgrade I'd consider; its current pricing/help pages put it around $29/month and specifically position it for competitor research. Ahrefs Help Center

If you tell me what you sell + your rough monthly traffic/revenue, I can also recommend the cheapest tool stack for your particular store (including free alternatives).

For a small ecommerce store on a tight budget, I’d start with Semrush—but use its free/limited features first rather than immediately paying for a full subscription.

My pick: Semrush

It’s the best all-around fit for what you described because you can research:

• Top competitor keywords — which organic terms send them traffic and which pages rank for them. www.semrush.com
• Keyword gaps — keywords competitors rank for that you don't. www.semrush.com
• Traffic channels — organic, paid, social, referral, email, display, etc. www.semrush.com
• Competitor discovery — its free Competitor Finder can identify sites competing with you in search. www.semrush.com

The catch: Semrush's deeper traffic-intelligence features can get expensive, so I wouldn't pay for the premium traffic package unless you're already getting enough revenue to justify it. www.semrush.com

The alternative I'd consider: Similarweb

Similarweb is actually better if your main question is "Where does this competitor's traffic come from?"

Its free website checker lets you inspect domains and provides traffic estimates, SEO keywords, referring domains, ads, and traffic-source breakdowns. www.semrush.comwww.semrush.comwww.similarweb.com It can break traffic into direct, organic search, paid search, social, email, referrals, and display. support.similarweb.com

So I'd rank them:

What I'd actually do with $0

Pick 3–5 competitors and run them through Semrush and Similarweb.

For each competitor, record:

1. Their top 20 non-branded keywords
2. Pages receiving the most organic traffic
3. Organic vs. paid vs. social vs. referral traffic
4. Their biggest referring websites
5. Keywords where they're ranking but you aren't
6. Products/pages that appear to be attracting the most search traffic

Then focus on high-intent keywords rather than simply chasing the biggest search volumes—for example, "buy waterproof hiking backpack" is generally more useful to an ecommerce store than "hiking".

If you tell me what you sell and give me 1–3 competitor websites, I can also show you exactly how I'd analyze them and what metrics I'd prioritize.

For a small ecommerce store on a tight budget, I’d start with Similarweb’s free tools rather than paying for an expensive all-in-one platform.

My pick: Similarweb

similarweb.com lets you enter a competitor's domain and see:

• Traffic sources: organic search, paid search, direct, social, referrals, email, etc.
• Top keywords driving traffic
• Referral sites sending visitors
• Traffic/engagement estimates
• Competitor comparisons

Similarweb explicitly offers its basic website checker for free, although smaller sites can have limited data. Similarweb Similarweb

If SEO/keywords are your main priority: Semrush

semrush.com is probably better for answering "Which exact Google keywords are my competitors winning?" It shows competitor keyword rankings, landing pages, estimated organic traffic, and keyword gaps. Semrush

The catch is cost: Semrush's full Traffic & Market competitor data is currently $289/month for Pro, with only sample-domain access on the free version. Semrush Semrush

What I'd do with your budget

Best $0 workflow: Take 3–5 competitors → run each through Similarweb → record their biggest traffic channels and top keywords → use Semrush to dig deeper into the keywords/pages that look achievable for your store.

One important caveat: competitor traffic numbers are estimates, not their actual analytics. Treat them as directional and look for patterns across multiple competitors rather than trusting a single traffic figure. Similarweb

If you tell me what you sell + your country + 2–3 competitor URLs, I can also show you exactly how I'd analyze them and which keywords I'd prioritize.

For a small ecommerce store on a tight budget, I’d pick Similarweb if your main goal is both competitor traffic sources + top keywords.

My ranking

Why Similarweb: its free website checker lets you enter a competitor and see traffic/engagement data, SEO keywords, referring domains, search ads, and—particularly useful—its traffic-source/channel breakdown. It currently allows 3 free searches per day on the checker. www.similarweb.com

Ahrefs is my second choice. Its free tools are excellent for finding the keywords and pages driving a competitor's organic traffic, but the ongoing free Site Explorer access is primarily for verified sites you own, so it's less useful for unlimited competitor spying. ahrefs.com

Semrush is arguably the strongest all-around paid option, showing competitors' best keywords, paid strategy, backlinks, and traffic trends. But its dedicated Traffic & Market product is currently $289/month, which I'd consider overkill for a small store on a tight budget. www.semrush.com

What I'd actually do

Start with Similarweb free + Ahrefs free, rather than paying for anything:

1. Put your 3–5 closest competitors into Similarweb.
2. Record their biggest traffic channels: organic, paid search, social, referrals, etc.
3. Pull their highest-value organic keywords.
4. Look for keywords where multiple competitors rank—those are especially interesting.
5. Use Ahrefs' free keyword/backlink tools to investigate the opportunities further. ahrefs.com
6. Only pay for Semrush/Ahrefs once you've found enough opportunities to justify the subscription.

If you tell me what you sell (e.g. skincare, jewelry, supplements, apparel) and roughly how much you can spend per month ($0, $20, $50, etc.), I can recommend the cheapest tool stack and a competitor-analysis workflow for your store.

For a small ecommerce store on a tight budget, I’d pick Ahrefs—specifically its lower-cost Starter/Free options—if your main goal is competitor keywords and SEO traffic.

My ranking

Why Ahrefs: Site Explorer can show a competitor's top organic keywords, estimated traffic per keyword, top-performing pages, paid keywords, and backlinks. Its current Starter plan is listed at £23/month, while Ahrefs also offers a free tier. ahrefs.com

Ahrefs Site Explorer

One caveat: if by "traffic sources" you specifically mean organic vs paid vs social vs referral vs email, Semrush is stronger. Its Traffic Analytics breaks competitor traffic down by channels and also provides top pages and keyword intelligence. www.semrush.com The problem for a tight budget is that its dedicated Traffic & Market Toolkit is currently $289/month, although Semrush offers a 7-day trial. www.semrush.com

Semrush competitor analysis

What I'd do in your shoes

Start with Ahrefs, and don't try to analyze 50 competitors. Pick 3–5 stores that are genuinely winning in your niche and for each:

1. Enter their domain into Site Explorer.
2. Export/find their top organic keywords.
3. Identify pages bringing them the most search traffic.
4. Look for keywords where they're ranking #3–20—those are often easier opportunities.
5. Check their paid keywords to see what they're willing to spend money on.
6. Compare your domain against theirs with Content Gap to find keywords you're missing. ahrefs.com

Bottom line:

• <$30/month: Ahrefs is my pick.
• Want the broadest competitor intelligence: Semrush.
• Want primarily SEO/keyword intelligence: Ahrefs.
• Don't pay for a big enterprise traffic tool yet—for a small store, turning competitor keyword data into 10–20 targeted product/category pages can produce much more value than exhaustive traffic analytics.

For a small ecommerce store on a tight budget, I’d pick Semrush as the best all-around competitor-analysis tool.

My ranking

Why Semrush: You can enter a competitor's domain and see its top organic keywords, paid keywords, traffic channels, backlinks, and trends. Its Keyword Gap feature is particularly useful for finding terms competitors rank for that you don't. www.semrush.com

For your specific goal, Similarweb is arguably better at answering "Where does their traffic actually come from?" It breaks traffic into organic/paid search, social, referrals, email, display, direct, affiliates and other channels, and its keyword reports show terms driving traffic to a competitor. www.similarweb.com

What I'd do with a tight budget

Don't pay for three tools. Start with Semrush's free competitor research tools and use its trial when you need deeper analysis. Semrush currently offers a free Competitor Finder that identifies organic competitors, shared keywords and estimated organic traffic. www.semrush.com

Then analyze your top 3–5 competitors and record:

1. Their top non-branded keywords
2. Keywords where they rank positions 1–20 and you don't
3. Their highest-traffic product/category pages
4. Organic vs. paid search traffic
5. Major referral sources
6. Social networks sending them traffic
7. Keywords they're actively paying for

That gives you a surprisingly useful competitor map without needing an expensive agency.

Bottom line: If you want one tool → Semrush. If your biggest question is specifically "how are competitors getting their traffic?" → Similarweb. Similarweb also has a free website traffic checker, so it's worth using alongside Semrush before spending anything. www.similarweb.com

If you tell me what you sell and your approximate monthly revenue/traffic, I can suggest the cheapest specific setup (including free tools) and a competitor-analysis workflow.

For a small ecommerce store on a tight budget, I’d start with Similarweb.

It’s particularly good for the two things you asked for:

• Top keywords: You can see keywords driving traffic to a competitor, including estimated clicks, search volume, CPC, organic vs. paid traffic, and ranking position. support.similarweb.com
• Traffic sources: It breaks competitors down by channels such as organic search, paid search, social, referrals, email, and display. www.similarweb.com
• Free starting point: Similarweb lets you analyze websites through its free traffic checker, although the amount of useful competitor data available without paying is limited. www.similarweb.com

What I'd use on a tight budget

Semrush is arguably more powerful for SEO, but its current Traffic & Market Pro plan is $289/month, while its free version only provides sample-domain data rather than real competitor analysis. www.semrush.com

A cheap competitor-analysis workflow

Pick 3–5 competitors and put each domain into Similarweb. For each one, record:

1. Top 10–20 organic keywords
2. Top paid keywords
3. Organic vs. paid traffic
4. Social traffic share
5. Top referring websites
6. Top landing pages

Then look for patterns. If three competitors are all getting significant traffic from something like “best [product] for [use case]”, that's a much stronger signal than one competitor ranking for a random high-volume keyword.

My recommendation: Don't spend $200–300/month on a tool yet. Use Similarweb's free capabilities alongside Google Search Console + Keyword Planner, and only pay for Semrush/Ahrefs once you're doing enough SEO/PPC work to justify it.

If you tell me what you sell and roughly who your competitors are, I can also suggest the cheapest tool stack and exactly what competitor metrics I'd track.

For a small ecommerce store on a tight budget, I’d pick Semrush as the best all-around competitor-analysis tool.

Semrush

Why Semrush fits your use case

• Top keywords: You can see the keywords sending organic traffic to a competitor, including rankings and estimated traffic. www.semrush.com
• Traffic sources: Its Traffic Analytics breaks competitor traffic into organic search, paid search, social, referral, email, display, and AI traffic. www.semrush.com
• Keyword gaps: You can compare your site against competitors to find keywords they rank for that you don't.
• Competitor discovery: Its free Competitor Finder can identify your actual search competitors based on shared keywords, without requiring a subscription. www.semrush.com
• Good for ecommerce: You can combine SEO research with paid-search/ad intelligence rather than paying for separate tools.

Semrush vs. Ahrefs

Ahrefs is an excellent alternative, particularly if your main goal is SEO and backlinks. Its Site Explorer shows competitors' top pages, keywords, organic traffic, paid traffic and backlinks, while its Organic Keywords report can sort competitor keywords by estimated traffic. ahrefs.com

Ahrefs Site Explorer

My budget strategy: start with Semrush's free competitor tools, identify 3–5 competitors, and build a spreadsheet of their top non-branded keywords + top pages + traffic channels. Only pay for a subscription once you know those insights will actually change what you're doing.

One caveat: competitor traffic numbers from tools like these are estimates, not their actual Google Analytics data. Ahrefs explicitly describes its organic-traffic figure as an estimate based on rankings, search volume and CTR. help.ahrefs.com

If you tell me what you sell + your approximate monthly revenue/traffic, I can recommend the cheapest tool/plan that makes sense and give you a 30-minute competitor-analysis workflow.

For a small ecommerce store on a tight budget, I’d pick Ahrefs Starter.

• Best budget choice: Ahrefs Starter — $29/month. It lets you analyze competitors’ organic traffic, top keywords, pages, backlinks, and paid-search data. The Starter plan specifically allows competitor research in Site Explorer. help.ahrefs.com
• Best overall competitor intelligence: Semrush. It has a broader view of competitor traffic sources—organic, paid, social, referral, email, display, and AI—and can show the keywords and pages driving traffic. www.semrush.com
• But Semrush gets expensive if you specifically want its full Traffic & Market data: the Pro Traffic & Market plan is currently $289/month. www.semrush.com

What I'd do in your shoes

Start with Ahrefs Starter at $29/mo, and use it to investigate your 3–5 closest competitors:

1. Put each competitor into Site Explorer.
2. Sort their organic keywords by estimated traffic.
3. Look for high-traffic, lower-ranking keywords (positions ~4–20) that you could realistically outrank.
4. Check their top pages to see which product/category pages are attracting search traffic.
5. Look at their backlinks to find sites that might also link to your store.
6. Check their paid-search reports to see which commercial keywords they're willing to spend money on. ahrefs.com

One useful free option before spending anything: Semrush's Competitor Finder can identify your top organic competitors and show their shared keywords and estimated organic traffic without requiring a paid subscription. www.semrush.com

Bottom line: Ahrefs Starter = best value for your situation. If your main question is “What keywords and pages are bringing my competitors Google traffic?”, it's plenty. If your question is “Where does their entire audience come from—Google, ads, social, referrals, email, AI, etc.?”, then Semrush is the stronger tool, but much harder to justify on a tight budget.

For a small ecommerce store on a tight budget, I’d start with Semrush, but use its free tools strategically rather than paying for the full platform immediately.

My pick: Semrush

Semrush is the best all-around option if your main questions are:

• What keywords are competitors ranking for?
• Which keywords bring them the most organic traffic?
• What keywords do we both rank for?
• What are their top pages?
• What are they doing with paid search?

Its free Competitor Finder can identify your top organic competitors and show shared keywords, total ranking keywords, and estimated organic traffic. www.semrush.comwww.semrush.comwww.semrush.comwww.similarweb.comwww.semrush.com Its keyword tools also let you research volume, difficulty, intent, and competitors ranking for a term. www.semrush.com

The catch: Semrush's full competitor traffic-source analysis is behind its paid Traffic & Market product; the free version only gives limited/sample-domain access. www.semrush.com

If traffic sources are your #1 priority: Similarweb

Similarweb Traffic Checker is arguably better for answering "Where does this competitor's traffic actually come from?"

It can show traffic channels such as organic search, paid search, social, referrals, email, display and direct, plus top keywords and referring domains. Its free traffic checker currently allows limited free analysis. www.similarweb.com

What I'd do with $0

1. Put your store into Semrush Competitor Finder.
2. Grab your 5–10 biggest organic competitors.
3. For each competitor, record their top non-branded keywords.
4. Look for keywords where they rank in positions ~3–20 but you don't rank.
5. Use Similarweb's free checker to identify whether their traffic is primarily search, social, referral, paid, or direct.
6. Only pay for a subscription once you've exhausted the free data.

Bottom line:
Semrush = better for finding the keywords you should steal/target.
Similarweb = better for understanding the overall traffic mix.

For a cash-conscious ecommerce business, I'd start with Semrush free + Similarweb free, rather than paying $100–300+/month for either immediately. Semrush currently offers a 7-day trial, while its full Traffic & Market Pro pricing is substantially more expensive than its basic SEO functionality. www.semrush.com

If you tell me what you sell and 2–3 competitors, I can also show you exactly how I'd analyze them and what metrics I'd look at first.

For a small ecommerce store on a tight budget, I’d start with Similarweb’s free Website Traffic Checker rather than paying for a full SEO suite.

Similarweb Website Traffic Checker lets you enter a competitor’s domain and investigate estimated traffic, traffic sources, top keywords, and referring sites. Similarweb specifically supports identifying the keywords driving traffic and breaking traffic down by channels. www.similarweb.com

My budget ranking

Why not Semrush? It's arguably the more comprehensive tool, but current pricing starts around $117/month for its basic offering, which is hard to justify when you're a small store. www.techradar.com

The cheap competitor-research workflow I'd use

For each of your 3–5 closest competitors:

1. Put their domain into Similarweb.
2. Look at traffic sources — search, direct, referrals, social, etc.
3. Pull their top organic keywords.
4. Prioritize keywords that have:
   • meaningful search volume
   • clear buying intent
   • reasonable competition
   • products/pages you can realistically beat
5. Check which competitors are getting traffic from the same keywords.
6. Use Google Trends to validate whether promising terms are actually growing or declining. Google's SEO toolset is free. www.techradar.com

One particularly useful Similarweb feature is keyword-gap analysis: it can show keywords sending traffic to competitors but not to you. support.similarweb.com

Bottom line: If you can spend $0 right now, use Similarweb + Google Search Console + Google Trends. If you're eventually willing to spend ~$100+/month and SEO becomes a major growth channel, then I'd evaluate Semrush.

If you tell me what you sell and your store URL, I can also suggest the exact competitor-analysis workflow and which metrics/keywords I'd focus on.

For a small ecommerce store on a tight budget, I’d avoid paying for the biggest all-in-one platforms right away. The best choice depends on whether you care more about SEO keywords or where competitors get traffic from.

Best budget picks

My recommendation for a small ecommerce budget

Option 1: Cheapest useful stack

• Use free versions/trials of:
  • Similarweb → see broad traffic sources
  • Google Search → manually inspect what keywords competitors rank for
  • Google Keyword Planner → find search demand
• Upgrade only when you know what you need.

Option 2: Around $40–$100/month

• Start with SpyFu or SE Ranking.
• Use it to answer:
  1. What keywords bring competitors traffic?
  2. Which product/category pages rank?
  3. Are they buying Google Ads?
  4. What keywords are they ranking for that I’m missing?

Option 3: If SEO is your main growth channel

• Save up for Semrush or Ahrefs. They are more expensive but better when you’re doing serious content and SEO campaigns. www.semrush.comwww.analook.com

A practical workflow:

1. Pick your top 5 competitors.
2. Export their top 50–100 keywords.
3. Filter for:
   • high purchase intent (“buy,” “price,” “best,” product names)
   • keywords where they rank positions 3–20 (easier wins)
   • keywords where multiple competitors overlap
4. Create better product/category pages around those gaps.

For a small ecommerce store, I’d probably start with SpyFu or SE Ranking, then move to Semrush/Ahrefs only when you’re publishing enough content or running enough SEO campaigns to justify it. www.techradar.comsuperframeworks.com

For a small ecommerce store on a tight budget, I’d avoid paying for a huge enterprise suite unless you’ll actually use it. The best choice depends on whether you care more about SEO keywords or overall traffic sources:

www.semrush.com

My pick for a bootstrapped ecommerce store

Start with SpyFu + free tools.

Why:

• You can enter a competitor’s domain and see:
  • their top organic keywords
  • keywords they buy ads for
  • estimated SEO traffic
  • pages bringing them traffic
• It’s usually more affordable than the big SEO suites. www.reddit.comwww.similarweb.com

Then add:

• Similarweb free version → to answer “where are their visitors coming from?” (Google, social, referrals, direct, etc.). www.similarweb.com
• Google Keyword Planner → to validate search volume before creating products/content.
• Google Search Console → to improve your own store once you have traffic.

If you can spend ~$100+/month

I’d choose Semrush. It gives you a broader competitor picture:

• keyword gaps (“keywords they rank for but you don’t”)
• competitor organic pages
• paid search insights
• backlink opportunities

www.semrush.com

A simple competitor research workflow (cheap but effective)

1. Pick 5–10 competitors:
   • direct product competitors
   • brands ranking above you on Google
   • marketplace sellers (if relevant)

2. For each competitor, record:
   • Top 20 keywords
   • Top 5 landing pages
   • Traffic channels
   • Their ad keywords
   • Content topics bringing visitors

3. Look for gaps:
   • keywords they rank for but you don’t
   • products/categories they don’t cover well
   • questions customers ask that they ignore

For most small ecommerce owners, SpyFu (keywords) + Similarweb (traffic sources) + Google’s free tools will get you 80–90% of the insight without a big monthly bill. www.reddit.comwww.similarweb.com

If you tell me your ecommerce niche (fashion, supplements, home goods, etc.) and monthly budget (even $0), I can suggest the leanest tool stack.

For a small ecommerce store on a tight budget, I’d focus on value-per-dollar rather than the most powerful enterprise tools. The best options for finding competitors’ top keywords, estimated traffic sources, and SEO gaps are:

Best overall budget choice: Semrush

Best for: seeing competitor keywords + traffic channels in one place.

What you can do:

• Enter a competitor’s domain and see:
  • Top organic keywords
  • Pages bringing in the most traffic
  • Paid search keywords
  • Backlinks
  • Traffic sources (search, direct, referrals, etc.)
• Use “Keyword Gap” to find terms competitors rank for that you don’t.

Downside: the free version is limited, and paid plans can get expensive. For a small store, you may only need a month occasionally to gather data and export ideas.

Best cheap/free alternative: Ubersuggest

Best for: small ecommerce owners who need basic competitor keyword research.

Good for:

• Competitor domain overview
• Top SEO pages
• Keyword ideas
• SEO difficulty estimates

It’s less detailed than Semrush but easier to justify on a small budget.

Best for seeing competitor traffic estimates: Similarweb

Best for: understanding where competitors get visitors.

Useful insights:

• Search vs social vs referrals vs direct traffic
• Top referring websites
• Audience interests
• Geographic traffic patterns

The free data can be limited, especially for smaller sites.

Best free SEO workflow (what I’d do with a small store)

1. Pick 5–10 competitors:
   • Direct competitors selling similar products
   • Sites ranking above you in Google

2. Use free tools:
   • Google Keyword Planner — find search demand
   • Google Search Console — understand your own rankings
   • Ahrefs Webmaster Tools — free backlink and SEO insights for your own site

3. If you can spend ~$100–150 for one month:
   • Subscribe to Semrush for a month
   • Export:
     • competitor keywords
     • top pages
     • keyword gaps
     • backlink opportunities
   • Cancel and use the data for months afterward

For a small ecommerce store, my ranking would be:

1. 🥇 Semrush — best competitor keyword + traffic research
2. 🥈 Ubersuggest — best low-cost option
3. 🥉 Similarweb — best for traffic source intelligence
4. Ahrefs — excellent SEO tool, but usually better once you’re scaling

If you tell me your store platform (Shopify/WooCommerce/etc.), product category, and monthly budget (e.g., $0, $50, $100), I can suggest the most cost-effective setup.

For a small ecommerce store on a tight budget, I’d prioritize value per dollar over the “most powerful” enterprise tools. The best options for finding competitors’ top keywords, traffic sources, and SEO opportunities are:

My pick for a small ecommerce store:

Start with Semrush if you can afford one paid tool. It gives the best mix of:

• “What keywords bring my competitors traffic?”
• “Which product/category pages rank?”
• “Are they buying ads for those keywords?”
• “Who are their SEO competitors?”

If the budget is extremely tight:

1. Use the free version of Semrush or Ubersuggest.
2. Pick 5–10 competitors.
3. Export or manually record:
   • Top 20 organic keywords
   • Keywords where they rank positions 3–20 (easier opportunities)
   • Highest-traffic pages
   • Referring websites
   • Paid search keywords (if available)

A practical low-cost workflow:

Step 1 — Find competitors

• Search Google for your main products.
• Note stores appearing repeatedly in the top results.

Step 2 — Reverse engineer them
Look for:

• Keywords with buying intent:
  • “best [product]”
  • “[product] for [specific use]”
  • “[product] discount”
  • “[product] vs [alternative]”
• Pages getting traffic:
  • /collections/
  • /products/
  • buying guides/blog posts

Step 3 — Turn findings into your own plan
Don’t copy their keywords blindly. Prioritize:

• High purchase intent
• Lower competition
• Keywords where competitors have weak content
• Products where you have better pricing, reviews, shipping, or expertise

For a very small ecommerce brand, I’d usually rank them:

1. Semrush — best all-around choice
2. Ahrefs — best if SEO/content is your growth channel
3. SpyFu — best if competitors run lots of Google Ads
4. Ubersuggest — best “start today for almost free” option

If you tell me your ecommerce niche (fashion, supplements, home goods, electronics, etc.) and monthly budget (e.g., $0, $20, $50/month), I can suggest the most cost-effective setup.

If you’re a small ecommerce store on a tight budget, I’d pick SpyFu for competitor keyword research—but there’s an important distinction:

My recommendation: SpyFu + free tools

For your specific goal—“What keywords bring my competitors traffic, and where does their traffic come from?”—I wouldn't jump straight to Semrush or Similarweb.

SpyFu is particularly useful for seeing competitors' organic keywords, paid keywords, rankings, and historical search data. It's a good fit when your main objective is finding search terms you can actually compete for.

For traffic sources, Similarweb is stronger. It breaks traffic into channels such as organic search, paid search, social, referrals, email, display, and direct traffic. support.similarweb.com

Semrush is probably the best single-tool answer if budget weren't a concern: its competitor research combines keywords, traffic channels, paid strategy, backlinks, and top pages. www.semrush.com But its dedicated Traffic & Market Toolkit currently starts at $289/month when billed annually, which is hard to justify for a small store. www.semrush.com

What I'd do with a tight budget

1. Pick 5–10 direct competitors.
2. Put each domain into SpyFu.
3. Export their top organic keywords.
4. Filter for keywords with:
   • buyer intent
   • decent search volume
   • manageable competition
   • products you actually sell
5. Check those competitors in Similarweb's free/basic data to see whether they're primarily getting traffic from search, referrals, social, etc.
6. Build your SEO/content plan around the 20–50 highest-value gaps, rather than trying to copy everything they rank for.

If you want one paid subscription only, I'd lean SpyFu for your situation. If your priority is specifically traffic-source intelligence rather than SEO keywords, I'd switch that recommendation to Similarweb.

If you tell me roughly what you sell (e.g. apparel, supplements, home goods, jewelry), I can also recommend the cheapest tool stack and exact competitor-analysis workflow for your niche.

If you're on a tight budget, you don't need an enterprise SEO suite. The best value depends on how much data you need and how often you'll use it.

Here's how I'd rank the options for a small ecommerce business:

My recommendation

For a small ecommerce store, I'd choose SE Ranking.

It provides:

• Competitors' top organic keywords
• Estimated search traffic
• Paid keywords (Google Ads)
• Backlink analysis
• Keyword gap analysis
• Ranking tracking
• Reasonably accurate traffic estimates

It's significantly less expensive than Semrush or Ahrefs while covering most of what a small business needs.

If your budget is under $40/month

Use this combination:

• Ubersuggest for competitor keywords
• Similarweb Free for traffic sources
• Google Search Console for your own SEO
• Google Trends for market demand

That gives you about 80% of the insights for a fraction of the cost.

What to analyze

When looking at a competitor, focus on:

1. Top organic pages
   • Which pages get the most traffic?
   • Are they category pages or blog posts?

2. Top keywords
   • High-volume keywords
   • Long-tail keywords with buyer intent
   • Keywords where they're ranking #1–10

3. Traffic sources
   • Organic search
   • Paid search
   • Social
   • Email
   • Referrals

4. Backlinks
   • Which sites link to them?
   • Can you earn links from similar sources?

5. Best-selling categories
   • Which product categories attract the most search traffic?

A simple weekly workflow

Every week:

• Check your top 3 competitors.
• Export their top 100 keywords.
• Filter for keywords where they rank in positions 3–20 (often easier to compete with than #1 rankings).
• Create or optimize one product page or blog post targeting one promising keyword.
• Track your rankings over time.

This process can steadily grow organic traffic without requiring a large marketing budget.

If you tell me what you sell (for example, supplements, pet supplies, clothing, home decor, electronics, etc.), I can also recommend the best competitor research workflow for your niche and point out which metrics matter most.

If your goal is finding competitors' top keywords, traffic sources, and SEO opportunities on a tight budget, I'd prioritize tools like this:

My recommendation by budget

💲 Under $30/month: Ubersuggest

• Shows competitors' organic keywords
• Estimates search traffic
• Displays backlink profiles
• Content ideas
• Easy to learn
• Excellent value for solo store owners

Great if you're running a Shopify, WooCommerce, or Etsy-related business.

💲 $30–70/month: SE Ranking
This is probably the sweet spot.

You get:

• Competitor keyword gaps
• Keyword rankings
• Organic traffic estimates
• Paid search research
• Backlink monitoring
• Website audits

Many small agencies use it instead of Semrush because it covers most everyday SEO tasks at a lower cost.

💲 Free combination (surprisingly effective)

Use these together:

• Google Search — see which pages rank.
• Google Keyword Planner — keyword ideas.
• Google Trends — demand over time.
• Similarweb Free — traffic channels (search, social, direct, referrals).
• Ahrefs Free Backlink Checker — top backlinks.

You won't get perfect numbers, but you'll uncover many of the same opportunities without paying much.

What I'd actually do each week

1. Pick your top 5 competitors.
2. Export their top 100 keywords.
3. Find keywords where they rank in positions 5–20.
4. Create better product pages or blog posts targeting those terms.
5. Check which websites link to competitors and pursue similar partnerships or mentions.
6. Monitor changes monthly rather than daily.

This approach tends to produce more actionable insights than chasing estimated traffic numbers alone.

If you can afford only one tool

• Best overall: Semrush
• Best value: SE Ranking
• Best for very small budgets: Ubersuggest
• Best for traffic-source analysis: Similarweb
• Best for backlink-focused SEO: Ahrefs

If you tell me:

• what platform your store uses (Shopify, WooCommerce, BigCommerce, etc.),
• roughly how many products you sell,
• and your monthly budget (e.g. $20, $50, or $100),

I can recommend the tool that will give you the highest return for your specific situation.

For a small ecommerce store on a tight budget, I'd prioritize tools that give you keyword rankings + traffic estimates + traffic sources without requiring an expensive enterprise subscription.

Here's how I'd rank them by value:

If I only had $30/month

I'd use:

1. Ubersuggest for:
   • Top organic keywords
   • SEO difficulty
   • Content ideas
   • Competitor keyword rankings

2. Google Search Console (free)
   • Your own keyword opportunities

3. Google Trends (free)
   • Seasonality
   • Rising searches

That combination gets you about 70–80% of what many stores actually need.

If you can spend around $60/month

I'd choose SE Ranking.

It includes:

• Competitor keyword tracking
• Organic traffic estimates
• Paid keyword research
• Backlink monitoring
• Keyword gap analysis
• Website audits

It's one of the strongest values for small businesses.

If you want to reverse-engineer competitors

The workflow I recommend is:

1. Enter a competitor's domain.
2. Export their top 500–1,000 organic keywords.
3. Sort by estimated traffic.
4. Filter for keywords with medium or low difficulty.
5. Create better product pages or blog content targeting those terms.
6. Check which pages attract the most traffic.
7. Repeat for 3–5 competitors and look for overlapping keywords.

This usually uncovers opportunities much faster than starting with keyword brainstorming.

Best overall recommendation

• Best overall: Semrush (if your budget allows)
• Best value: SE Ranking
• Best under $30/month: Ubersuggest
• Best for traffic-source analysis: Similarweb

If your budget is under $50/month, I'd lean toward Ubersuggest if your main goal is finding competitor keywords, or SE Ranking if you want a more complete SEO toolkit. Both provide strong value without the cost of enterprise platforms.

For a small ecommerce store on a tight budget, I would prioritize value per dollar rather than buying the biggest all-in-one platform.

Here's how I'd rank the best options for your specific goal (finding competitors' top keywords and traffic sources):

If your budget is under $50/month

I'd choose SpyFu.

Why:

• Find competitors' organic keywords
• See paid Google Ads keywords
• Keyword history
• Competitors ranking changes
• Much cheaper than Semrush or Ahrefs while covering the essentials. www.reddit.comwww.reddit.com

If your budget is around $100–150/month

Go with Semrush.

It's the strongest all-in-one option because you can:

• Discover competitors' top organic keywords
• Find keyword gaps
• Analyze backlinks
• Estimate traffic
• View paid search campaigns
• Research content ideas from one dashboard. www.semrush.com

If traffic sources are your biggest concern

Use Similarweb.

It excels at answering questions like:

• What percentage of traffic comes from Google?
• How much comes from social media?
• Which websites send referral traffic?
• Which countries drive the most visitors?
• Who are the site's audience overlaps? zapier.com

The budget stack I'd recommend

If I were running a small ecommerce business, I'd use:

• Google Search Console (free) — monitor your own keywords.
• Similarweb Free — estimate competitors' traffic sources.
• SpyFu — competitor keywords and Google Ads.
• Google Keyword Planner (free) — validate keyword volume.

That combination gives you most of the insights many small stores actually act on without paying for a full enterprise SEO suite. Community discussions from bootstrapped founders often recommend pairing a lower-cost SEO tool with Similarweb's free features instead of buying a single expensive platform. www.reddit.comwww.reddit.com

If your store does over $500k/year in revenue or SEO is your primary acquisition channel, upgrading to Semrush usually makes sense. Otherwise, I'd keep costs low and invest the savings into creating content or running ads.

If you're on a tight budget, the best tool depends on how much data you need versus how much you're willing to spend. Here's how I'd rank the options for a small ecommerce store:

My recommendation by budget

💰 Under $30/month: SE Ranking

For most small ecommerce stores, this offers the best balance of price and features.

You can:

• Find competitors' top-ranking keywords
• Estimate their organic traffic
• See which pages drive the most traffic
• Track your own rankings
• Research keyword difficulty

💰 Around $30–50/month: Ubersuggest

Pros:

• Very affordable
• Easy to use
• Shows competitors' top keywords
• Shows estimated SEO traffic
• Content ideas

Cons:

• Traffic estimates aren't as accurate as Semrush or Similarweb.

💰 $100+/month: Semrush

If you can justify the cost, it's the most complete solution for ecommerce competitor analysis.

You can see:

• Organic keywords
• Paid keywords (Google Ads)
• Traffic sources
• Top landing pages
• Backlinks
• Shopping competitors
• Keyword gaps
• Market share

If traffic sources are your main goal

Use Similarweb.

It breaks traffic down into:

• Organic search
• Paid search
• Social
• Email
• Display ads
• Referrals
• Direct traffic

That's something SEO-focused tools don't do nearly as well.

Best free workflow

If your budget is close to zero:

1. Google Search
   • Search your main products.
   • Record the stores consistently ranking above you.

2. Google Search Console
   • Find your own opportunities.

3. Use the free versions of:
   • Ubersuggest
   • Similarweb
   • Ahrefs Webmaster Tools (for your own site)

Even with free limits, you can build a decent picture of competitors.

The workflow that typically delivers the biggest ROI

Instead of trying to copy everything a competitor does:

1. Pick your top 5 competitors.
2. Export their top 100 organic keywords.
3. Filter for keywords with:
   • High traffic
   • Buyer intent ("buy", "best", product-specific searches)
   • Lower keyword difficulty
4. Identify pages where multiple competitors rank well.
5. Build content or product pages that are more comprehensive, faster, and better optimized.

This approach usually produces better results than chasing every keyword a competitor ranks for.

If you can share what platform your store uses (Shopify, WooCommerce, BigCommerce, etc.) and your approximate monthly marketing budget, I can recommend the most cost-effective tool combination for your situation.
