Competitor research for founders using free tools

You can run solid competitor research for free by combining a traffic estimator, a few search operators, your browser's developer tools and a spreadsheet. The goal is not to copy anyone. It is to learn who you are really up against, where their audience comes from, what they charge and where they leave gaps.

This guide gives you a repeatable process that takes a few hours, plus a template for the notes worth keeping.

Step 1: build the competitor list

Start with three groups.

• Direct competitors. Products that solve the same problem for the same buyer.
• Indirect competitors. Different approaches to the same job, such as spreadsheets, agencies or general AI assistants.
• Aspirational peers. Companies a stage or two ahead of you that you can learn from.

Search your main phrases on Google and note who appears in the top results and in ads. Check app stores and community threads where users ask for recommendations. Browse your category in the AI startups directory for names you may have missed. Aim for eight to twelve names, then narrow to the five that matter most.

Step 2: size them with traffic estimates

Before you study details, find out who is big and who is small. A rival with a few thousand monthly visits plays a different game from one with millions.

Enter each domain into the traffic checker to get modelled monthly visits, top regions and an estimated revenue range. Those estimates come from public popularity lists, which are Tranco, Cloudflare Radar, Chrome UX Report, Cisco Umbrella and Majestic. The methodology page explains how they are combined. The revenue figure is a rough estimate based on visits, an assumed paying share and the lowest paid plan, so treat it as an order of magnitude only.

It helps to know where the numbers come from. The Chrome UX Report, for example, is a Google dataset of how real Chrome users experience popular sites, and it only includes origins that are publicly discoverable and have enough visitors for statistically meaningful data. That means small sites may be missing or imprecise. For a larger list, the bulk checker runs many domains at once.

Then look at momentum. The trending leaderboard and new sites leaderboard show which sites are climbing. A small competitor that is growing quickly deserves more attention than a big one that is flat.

Step 3: study their positioning and pricing

Read each competitor's homepage and pricing page as a customer would.

• What is the headline promise, and who is it for?
• Which features does the pricing page highlight, and which limits does it set?
• Is there a free plan, a trial or a demo-only model?
• Which testimonials and logos do they show?
• What do they say they are better at than alternatives?

Put the answers in a spreadsheet with one row per competitor. Save screenshots and the date, because pricing pages change. Add review sites and community threads to learn what users praise and complain about. Complaints are especially useful, since they point to unmet needs.

Step 4: audit their SEO

You can learn a lot about a rival's search strategy without paid tools.

1. Search operators. Use site:competitor.com in Google to see how many pages are indexed and which types exist, such as blog posts, comparison pages or programmatic templates.
2. Page titles and headings. Click through top pages and note which phrases they target. Google's SEO starter guide explains why titles and descriptions matter, so check how clear and unique theirs are.
3. Site structure. Open their sitemap if it is public and look at the sections.
4. Content gaps. Search topics your buyers care about and see where competitors are missing or thin.
5. Speed and usability. Test their key pages and compare with yours. Google's Core Web Vitals guidance gives the targets for loading, responsiveness and layout stability.

The traffic checker also runs a 16-point SEO audit on any domain, which saves time. For a longer explanation of each check, see our SEO audit checklist.

Step 5: identify their traffic channels

Once you know the size, ask where visitors come from. Free clues include:

• Top regions. The traffic checker shows top countries based on Chrome UX Report country lists, which indicates where a product is strong.
• Social and community presence. Check how often they post, how people respond and which platforms they favor.
• Launch and directory listings. Search for their name on launch sites and directories to see where they appear. Our post on launch sites and directories explains what to expect from them.
• Ads. Search public ad libraries and watch for repeating creatives, which often indicate what works.
• Newsletters and sponsorships. Subscribe to niche newsletters in your category and see who advertises. See where to buy niche ads.
• AI assistants. Ask ChatGPT, Perplexity and similar assistants for recommendations in your category and note which competitors they mention. We cover why in how AI assistants send traffic.

Step 6: look at their stack and infrastructure

Technology tells you how a team operates. Check the framework, hosting, analytics and marketing tools using the methods in our guide to tech stack detection. You can also check the domain age and registrar with a WHOIS or RDAP lookup. Neither tells you how good the product is, but both help you spot capacity and priorities.

Step 7: test the product

Nothing replaces using the product. Sign up for free plans, run a typical task and note:

• How long onboarding takes.
• Where you hit friction or limits.
• What output quality looks like, for AI tools especially.
• How support responds if you ask a question.
• What emails they send afterward.

Take notes as a customer, not as an engineer. Follow the rules of each service and do not abuse trials.

Step 8: find the gap

Combine everything into a simple matrix. Put competitors across the top and the criteria down the side, such as price, target customer, strongest feature, weakest point, main channel, estimated traffic and growth trend. Look for patterns.

• Underserved segments. A group that no one addresses well.
• Price gaps. A tier that is missing between cheap and enterprise.
• Feature gaps. A job that users keep complaining about.
• Channel gaps. A place where your audience gathers and no competitor is active.
• Content gaps. Questions people ask that no one answers well.

Your positioning should come from one or two of these gaps, supported by evidence.

A repeatable template

Keep a living document with these columns: name, URL, category, estimated monthly visits, trend, top regions, pricing summary, main promise, strengths, weaknesses, SEO notes, channels, tech notes and date last checked. Review it every quarter, and set a calendar reminder for pricing pages.

Mistakes to avoid

• Trusting estimates as facts. Public-list models are directional. Use ranges and trends.
• Copying instead of differentiating. If you mirror the leader, you compete on their terms.
• Ignoring tiny rivals. New entrants often foreshadow shifts.
• Researching forever. Set a time box, then make a decision and test it.
• Over-focusing on features. Distribution, trust and speed of execution matter at least as much.

FAQ

What free tools do I need for competitor research?

A traffic estimator, Google search operators, your browser's developer tools, a spreadsheet and the competitor's own product are enough. Add review sites and community threads for customer voice.

How accurate are free traffic estimates?

They are rough. Free estimates built from popularity lists work well for comparing sites and spotting trends, but exact visit counts will differ from a site's own analytics.

How often should I update my research?

Quarterly is a good rhythm, with extra checks when a competitor raises money, changes pricing or launches a major feature.

Is competitor research legal?

Studying public pages, public listings and products you can legitimately sign up for is standard practice. Do not access private data or break a service's terms.
