Free AEO Checker & GEO Audit

Answer engine optimization (AEO), also called generative engine optimization (GEO), is the work of getting your pages read, understood and cited by AI engines such as ChatGPT, Perplexity, Gemini and Google AI Overviews. This checker covers the technical half of that work — the part you can verify from the page itself.

• Crawler access — whether robots.txt lets the search and training bots of OpenAI, Anthropic, Perplexity and Google reach this URL. Search bots weigh more, because they feed the answers that cite you.
• Site files — HTTPS, robots.txt, llms.txt and an XML sitemap.
• Structured data — valid JSON-LD, an Organization (or LocalBusiness) entity, and markup describing the content: Article, Product, FAQPage and so on.
• Content — how much text exists in the raw HTML before JavaScript runs, a single H1, question-style headings and a <main> landmark.
• Meta tags — title, description, canonical, noindex and og:image.

Each check is worth points; a warning earns half. The grade is the share of points earned: A from 85%, B from 70%, C from 55%, D from 40%, F below that. The bars show which category costs you the most.

Fix failures before warnings, and fix them in this order: anything that blocks access (a search bot disallowed, a noindex tag, content that only appears after JavaScript), then entity signals (Organization schema), then polish. A page that AI crawlers can't read will not be cited however good its schema is.

The grade measures readiness, not visibility. A page can score A and still never be mentioned, because engines also weigh what other sites say about you. To see whether you actually appear in answers, use the AI visibility checker.

AI search engines retrieve pages first and write the answer second. Retrieval depends on the same basics as classic search: the crawler must be allowed in, the content must be in the HTML it downloads, and the page must say plainly what it is. Most AI crawlers do not execute JavaScript, so a client-rendered page can look empty to them while looking fine in your browser.

Structured data and clear headings help at the next step, when a model picks passages to quote. The GEO paper from Princeton and others (arXiv:2311.09735) found that content changes such as adding sources, statistics and quotations changed how often pages were cited in generated answers. This checker won't judge your writing, but it makes sure nothing technical stands in the way.
