Free website audit: SEO, AEO and GEO
One URL, 14 checks. The usual SEO fundamentals — title, meta description, one H1, canonical, sitemap — plus the half most audits skip: whether an AI assistant can read your page at all.
Every line is read from your own HTML, robots.txt, llms.txt and sitemap. Nothing is inferred and no model is asked for an opinion, so the same page scores the same every time.
The check that catches most people
The crawlers behind ChatGPT, Claude and Perplexity don’t execute JavaScript — Vercel and MERJ confirmed it across more than 500 million GPTBot fetches. A site built as a client-rendered app can rank perfectly well in Google, whose crawler does render, and still be an empty page to every assistant.
You cannot see that in a browser, because your browser runs the JavaScript. That is the first check this runs, and it is the one worth fixing before any of the others.
Want the same check per crawler, with the real status code each one gets? The AI crawler check fetches your page as each agent individually.
Questions
Frequently asked questions
Is this really free?
Yes, and there is no signup. It is rate limited to a handful of scans per visitor because each one makes real outbound requests to the site you point it at, but nothing is held back behind an account.
What do AEO and GEO actually mean?
Answer Engine Optimization and Generative Engine Optimization: being readable and quotable by assistants like ChatGPT, Claude and Perplexity, rather than only ranking in a list of blue links. The two overlap heavily with classic SEO, but they add one requirement most sites fail silently — the page has to carry its content in the HTML, because those crawlers do not run JavaScript.
How is this different from Lighthouse or a classic SEO tool?
Lighthouse measures performance and accessibility in a rendering browser, which is exactly the environment an AI crawler is not. This checks the things that decide whether an assistant can read and quote the page at all, and reports what was found rather than a rendered-page score.
Does it use AI to grade my page?
No. Every check reads evidence directly from your HTML, robots.txt, llms.txt or sitemap.xml, so the same page gives the same result every time. Asking a model whether it likes your site returns a different answer on repeat runs, which is not a measurement.
Will a good score get me cited by ChatGPT?
No, and nobody can promise that. What the checks cover is the mechanical part — whether a crawler can reach the page, read it without JavaScript, and find structure worth quoting. Those are necessary, not sufficient. Anyone selling a guaranteed citation is guessing.
