The best free SEO tools in 2026, by the job they do

Free means you can use it now with a sign in, no card. A trial that locks when days or credits run out is not the same as free.

• Data ownership: can you export your work, or only view it on their site
• Coverage: does it show just your site, or the wider web
• Sampling: some free reports show samples, not full sets
• Freshness: some indexes refresh slower on free access
• Scale: caps on URLs crawled, queries shown or locations tested
• Support: free tools rarely explain results for you

You run a small product. You want the tools that show your own truth first. Then use free web-wide tools when you need a wider view.

Start here. These show what your real users did, or tried to do, on Google and Bing. Add Ahrefs’ free site tools for a second lens on your own domain.

• Google Search Console: free. Queries, pages, impressions, clicks, positions, indexing, sitemaps, Core Web Vitals, enhancements. Pre click.
• Bing Webmaster Tools: free. Backlinks, keyword research, IndexNow and site reports.
• Ahrefs Webmaster Tools: free for verified sites. Site Audit and Site Explorer on your own site, powered by Ahrefs’ link index and DR.
• Google Analytics 4: free. Event based. Sessions, pages, events and conversions. Post click. It will not match Search Console exactly.

1. 1

   Verify your site in Search Console and Bing

   Add both www and non www, HTTP and HTTPS if you have them. Submit your XML sitemap. Check the Coverage or Indexing reports weekly.

2. 2

   Read the Performance report

   Sort by pages, then queries. On "/pricing", see queries like "yourproduct pricing". If impressions are high and clicks low, fix the title and meta.

3. 3

   Scan indexing issues

   Open reports like Crawled, currently not indexed. Click a URL and use URL Inspection to request indexing after a fix.

4. 4

   Run Ahrefs Webmaster Tools on your site

   Use Site Audit to catch broken links and slow pages. Use Site Explorer on your domain to see referring domains and top linked pages.

5. 5

   Keep GA4 separate

   Build a Landing page report. Track signups from organic. Do not try to reconcile GA4 sessions with Search Console clicks.

A fixed page example: "/guides/getting-started" shows 5,000 impressions, 14 clicks for "getting started with yourproduct". You add clearer H1 and a step list. Next week clicks rise without new content.

Test in the lab, then confirm with field data. Fix the slowest pages that users see most, not a random score in a tool.

• PageSpeed Insights: runs Lighthouse and shows Chrome UX Report field data.
• Lighthouse in Chrome DevTools: open locally, change network and CPU, repeat quickly.
• WebPageTest: detailed waterfalls and filmstrips, choose locations and devices.
• GTmetrix: built on Lighthouse, with waterfalls. Monitoring sits on paid plans.
• Chrome DevTools Performance panel: record a real page load and interaction.

1. 1

   Find slow pages with real users

   Open PageSpeed Insights with "/pricing". Check field data. If LCP is above 2.5 seconds, scroll to Opportunities for exact files.

2. 2

   Reproduce in Lighthouse

   Run Lighthouse in DevTools while throttled. Note the Largest Contentful Paint element. Optimise that image or block first.

3. 3

   Check layout stability

   Use the Web Vitals extension. If CLS is above 0.1, set image sizes and reserve space for embeds.

4. 4

   Confirm the fix in field data

   Wait one to two weeks. Recheck PageSpeed Insights and the Core Web Vitals report in Search Console.

A fixed page looks like this: "/pricing" swaps a hero video for a still image, compresses it, sets width and height, cuts a render blocking script. LCP drops under 2.5 seconds.

You do not need a suite for schema. Test your JSON LD and only use types that match your page. Wrong schema is ignored at best.

• Rich Results Test: checks if Google can render and if a page is eligible for rich results.
• Schema Markup Validator: validates schema.org syntax without judging eligibility.
• Chrome DevTools: view rendered HTML and the Elements panel to confirm the JSON LD is present after hydration.

1. 1

   Pick the right type

   On "/pricing" use no FAQ unless there is a visible FAQ. On "/guides/getting-started" add HowTo only if steps are present.

2. 2

   Validate

   Paste the URL into the Rich Results Test. Fix missing or malformed fields. Then run the Schema Markup Validator for syntax only.

3. 3

   Ship and monitor

   Deploy. Watch the Enhancements and Search appearance reports in Search Console for coverage and clicks.

A fixed page: "/guides/getting-started" adds a visible FAQ and valid FAQPage JSON LD. People also ask clicks rise and the snippet is cleaner.

Use your own queries first. Then expand with free sources to find terms you can win. Keep a short list you can actually publish against this month.

• Search Console’s queries for the last 28 days.
• Google Trends for relative interest over time.
• Autocomplete and People also ask on the results page.
• Bing Webmaster Tools Keyword Research with volumes.
• Keywords Everywhere to add volumes on the results page.
• AnswerThePublic for autocomplete wheels of questions and comparisons.
• AlsoAsked for People also ask trees by country and language.

1. 1

   Mine your near wins

   In Search Console, filter average position between 8 and 20. These striking distance terms are your quick wins with on page fixes and links.

2. 2

   Expand with questions

   Put your seed term into AlsoAsked and AnswerThePublic. Group similar questions. Pick three that match your product.

3. 3

   Check seasonality and language

   Open Google Trends. If interest spikes, plan the post earlier. If you serve multiple regions, repeat by country in AlsoAsked.

4. 4

   Decide the page type

   Look at the top results. If they are how to guides, write a guide. If they are category pages, do not target with a thin post.

A fixed plan: yourproduct.com adds "/compare/yourproduct-vs-competitor" after seeing "yourproduct alternative" rise in Search Console and in Trends. It picks features users ask in People also ask and answers them clearly.

You need a crawl to catch broken links, missing titles and redirect chains. A desktop crawler gets you far on a small site.

• Screaming Frog SEO Spider: desktop on Windows, macOS and Linux. The free version crawls up to 500 URLs. It produces tables you interpret.
• Sitebulb: desktop and cloud. Known for explained audit hints and visual crawl maps.
• Lumar and Oncrawl: cloud crawlers suited to large sites and teams.

1. 1

   Run a focused crawl

   Point Screaming Frog at your root. Set a crawl limit near your site size. Export 3 reports: Response Codes, Page Titles, Redirect Chains.

2. 2

   Fix what blocks users

   Start with 404s linked from live pages. Then fix duplicate or missing titles. Cut chains longer than one hop.

3. 3

   Re crawl and document

   Re run the crawl. Note remaining issues. Store the exports for a before and after record.

A fixed result: "/blog/old-post" returns 404 and is linked from "/blog". You redirect it to "/blog/new-post" and update the internal link. The next crawl is clean and clicks consolidate.

Links still matter. Use free sources to see who links to you and where you have gaps against obvious rivals. Do outreach with a small, focused list.

• Search Console Links report: a sample of your own links, free.
• Bing Webmaster Tools Backlinks: free, includes a rival comparison view.
• Ahrefs Webmaster Tools: Site Explorer on your verified domain, with Domain Rating as a link based score.
• Moz Link Explorer and Majestic: established backlink tools. Majestic has Trust Flow, Citation Flow and Topical Trust Flow. These focus on links only.

1. 1

   Pull your link lists

   Export top linking domains from Search Console and AWT. In Bing, add a rival domain to compare referring domains.

2. 2

   Spot easy wins

   Find brand mentions without links. Find broken links to old URLs. Reach out with the correct target URL ready.

3. 3

   Plan two assets to earn links

   For a SaaS, ship "/research/state-of-x" or a useful calculator. For a store, a size guide or a study. Link to these from your navigation.

A fixed gap: a blog lists yourproduct without a link. You email the editor with the exact page. They add it. Your referring domains rise by one with real relevance.

Build pages that answer real questions in your buyers’ words. Free tools expose these fast. Then you write short, direct answers high on the page.

• AlsoAsked: maps People also ask questions as trees. Good for structure.
• AnswerThePublic: autocomplete wheels by questions, prepositions and comparisons. Good for breadth.
• People also ask on the results page: manual, fast, fresh.
• Search Console: what users asked to find your existing pages.

1. 1

   Pick one seed topic

   For example, "yourproduct pricing" or "how to migrate to yourproduct". Use your own brand and your core job to be done.

2. 2

   Map intent and structure

   Use AlsoAsked to form H2s. Keep each page to one intent. Move side questions to separate pages to avoid cannibalisation.

3. 3

   Write answer first

   Open with a two line answer. Add steps, a screenshot and a signpost to a deeper guide. Keep titles under about 60 characters.

A fixed snippet: "/guides/migrate" starts with a two sentence answer to "Can I import from X" and a three step list. It earns a featured snippet for "migrate from X to yourproduct".

Track if assistants cite you. This is new work, but you can start for free. Do not expect steady traffic yet. Treat it as brand presence.

• Manual checks: ask buyer questions on a schedule and note if your brand appears or is cited.
• Tools built for this space: Profound, Peec AI, Otterly, Scrunch, Semrush’s AI toolkit, Ahrefs Brand Radar.

What to do with a finding: if your guide is quoted, add a summary box, a clean title and a short URL. If a rival is cited, study their page structure and headings and fill the gaps on yours.

Free gets you live data on your site, a crawl of a small site, and basic keyword and link views. It misses scale, history and deep rivals’ data.

• Competitive and keyword depth: Ahrefs, Semrush and Moz have broad keyword tools and large link indexes. Pick one when you need consistent depth.
• Rank tracking at scale: rank trackers like SE Ranking, Semrush Position Tracking, Ahrefs Rank Tracker, AccuRanker, Nightwatch and Mangools SERPWatcher track daily.
• Large and explained crawls: Sitebulb explains issues with priorities. Lumar and Oncrawl handle large sites in the cloud.
• Backlink specialists: Majestic runs its own index and offers Trust Flow by topic. Use when links are your main job.
• Traffic estimation: Similarweb estimates competitor traffic and sources. Treat its figures as approximations, rough for small sites.
• Beginner friendly all in ones: Mangools and Ubersuggest focus on simple workflows for small teams. SpyFu focuses on keyword history for search and paid.

Pick a paid tool only when a free tool blocks a clear next step. For example, you cannot size a keyword set for a new category with only Search Console. Or your store is larger than the free crawl limit in Screaming Frog.
