Free SEO tools for Google and AI search
Eight free tools that check what search engines and AI assistants actually get from your site: whether a page can be indexed, whether crawlers are blocked, what the HTML says without JavaScript, and exactly what to fix. Start with the SEO checker; it runs every check on one URL.
- SEO checker and page analyzerIndexability, canonical, title tag, meta description, headings, sitemap, internal links, structured data and load time for any URL, with the fix for each issue.
- AEO checkCan an answer engine find the answer on your page, lift it out cleanly and trust its source: answer-first content, passage length, headings, FAQ schema and author signals.
- GEO checkCan ChatGPT, Claude and Perplexity reach and cite the page: robots.txt rules for 31 AI crawlers, firewall blocks and content readable without JavaScript.
- AI crawler checkerWhich AI bots your robots.txt allows or blocks, by name, for search, training and user-triggered fetches.
- Cloudflare and firewall bot checkDetects Cloudflare, reads its managed robots.txt and Content-Signal line, then requests the page as ChatGPT's, Claude's and Perplexity's search bots to catch blocks robots.txt doesn't show.
- robots.txt generator for AI crawlersBuilds a robots.txt that allows AI search and blocks AI training, or any mix you choose, from the current list of crawler names.
- AI Overviews eligibility checkerFinds the tags and headers that keep a page out of Google's AI Overviews and AI Mode, such as noindex, nosnippet and max-snippet, plus the Bing equivalents for Copilot.
- Search Console AI report analyzerJoins Search Console's Generative AI report with the Performance report to show each page's share of visibility from AI Overviews and AI Mode. Files stay in your browser.

Questions
Are these SEO tools really free?
Yes. Every tool on this page runs without an account. The page audit shows every check's result and the full fix for the top three issues for free; a one-time ₹499 report unlocks every fix for a site.
What do these tools not do?
They don't estimate keyword volumes, track rankings or count backlinks, because that needs a large index of the web. For those, see our comparison of SEO suites and keyword tools, with prices from each vendor's site.
Which tool should I start with?
The SEO checker. It runs the full audit on one URL in about 20 seconds and covers both Google and AI search, so it shows which of the specialised tools you need next.
