This free AI SEO checker grades any page from 0 to 100.

An AI SEO checker is a tool that tests whether a web page is ready for AI search: whether AI crawlers can fetch it, read its text without running JavaScript, tell who published it and quote its answers. RankX AI’s AI Readiness Score runs 16 such checks on one page and grades it from 0 to 100.

Yes. The AI Readiness Score is free, needs no account and asks for no email. Each run checks one URL, a visitor can run ten checks an hour and any one domain can take six, and a repeat check of the same URL inside 24 hours returns the cached result instantly.

A classic free SEO checker, or SEO analyser as many call it, grades a page for Google search: title tags, meta descriptions, headings, keywords, speed and links, returned as an SEO score and a list of on-page SEO issues. An AI SEO checker asks an earlier question: can the AI assistants’ crawlers fetch the page at all, is the text in the HTML they read, and can they tell who you are and quote you. The AI Readiness Score does not grade titles or keywords; RankX AI’s SEO audit tool covers that side across a whole site.

The AI Readiness Score checks one page per run, by design, so you can test the exact page you care about. The free AI search readiness audit, a free SEO audit for AI search, samples up to six key pages on the same rubric and adds the four checks that need more than one page, such as whether a pricing page exists. A full crawl of up to 2,000 pages is part of the RankX AI product.

The AI Readiness Score measures whether a page is mechanically able to be found, read and quoted by AI search. Its checks sit in six groups: reach (can AI crawlers fetch it), read (can a machine parse it), know (does structured data say who you are), answer (does the page answer questions), trust (are authors named) and freshness (does the page say when it was true). It is a property of your page, not a poll of what assistants say about you.

Reach does: it holds 37% of the rubric’s weight. A robots.txt that blocks everything, AI search crawlers turned away, text that appears only after JavaScript runs, a noindex tag or a nosnippet directive each removes the page from AI answers before anything else matters. Perfect schema on a page nobody can fetch scores nothing, so the rubric weights reach first and says so.

Yes, in full, on this page: every check, its weight and its pass condition. An SEO report whose rubric is secret cannot be checked by the person it grades. RankX AI publishes it because a score is only useful when you can see what to fix and confirm the change yourself, and the same rubric runs inside the RankX AI product, so the two scores agree.

Yes. When fewer than two checks can be assessed, usually because the page could not be fetched from our server, the result is no score rather than zero. A zero would say the page failed everything; no score says it could not be measured. Every check that was not assessed is marked as such, and the score is computed only over the checks that were.

The best evidence says no. In 2026 Ahrefs tracked 1,885 already-cited pages that added schema, matched them against 4,000 control pages, and found no citation lift in Google AI Mode or ChatGPT and a small decline in AI Overviews it could not pin on schema. Schema keeps a place in the rubric for entity resolution, at modest weights, and every fact in your markup should also be in your visible text.

Because retrieval quotes the top of a page. Kevin Indig’s 2026 analysis of 18,012 verified ChatGPT citations found 44.2% came from the first 30% of the page. The check is deliberately simple: it looks for a real paragraph of at least 15 words straight after the main heading, a mechanical stand-in for opening with the answer rather than building up to it.

At the top of the result, which lists failed checks heaviest first, so the issues costing the most AI search visibility come first. Usually that means unblocking the AI search crawlers in robots.txt and at your CDN, which the AI Crawler Access Checker diagnoses per bot; then getting your real content into the server HTML rather than behind JavaScript; then removing any noindex or nosnippet you did not mean. Only after that are entity schema, dates and the opening paragraph worth polishing.

With the first half of it. ChatGPT search reads pages through OAI-SearchBot, and the AI Readiness Score confirms your robots.txt lets it and the other AI search crawlers in and that your text is in the HTML they fetch, which is where ChatGPT SEO starts. Whether ChatGPT then names your business is a different test, which the AI Visibility Checker runs.

RankX AI ran it on its own site on 1 October 2026, and the homepage, the pricing page and the AI visibility feature page each scored 100. A company selling AI search readiness should clear its own published rubric, and the date is there so you can run the same check on the same pages yourself.

Not directly, and no tool can promise that. The AI Readiness Score is RankX AI’s own measurement, and Google states that third-party tools have no access to its internal ranking data. Several checks do overlap with technical SEO that every search engine cares about: a noindex tag, a robots.txt block or text missing from the HTML hurts Google search too. For keyword rankings, search results and organic traffic, the Google rank tracker and Google Search Console are the measures to watch.

After any template, framework or CDN change, and monthly otherwise, alongside your regular SEO audits. Scores move when a framework changes how it renders, when a CDN changes its bot rules, and when an edit quietly empties the first paragraph, and none of those needs anyone to decide to fail. Results are cached for 24 hours per URL, so a re-check on the same day shows the earlier result: re-score the day after a change.
