What we check
Access
Whether the page answers crawlers at all, carries a noindex, serves HTTPS, and lets each AI crawler in through robots.txt, read with the RFC 9309 rules: a bot’s own group first, the * group when it has none, the longest matching rule wins.
Identity
The canonical URL, the title and description, and the Schema.org JSON-LD, checked field by field against the same rules Rank Prompt’s site audit uses, @graph containers included.
Readability
One H1, sections in heading order, a declared language, a mobile viewport, alt text, and enough HTML text for an engine to quote. Plus the sitemap, opened one level when it is an index, with a sample of its URLs fetched.

What is an AEO checker?
An AEO (answer engine optimization) checker tests whether AI engines like ChatGPT, Gemini, Perplexity and Google AI Mode (AI Overviews) can reach, read and cite a page. This one lists what to fix, the problems that keep engines out first.
Which AI crawlers does it check?
The same list as our robots.txt AI checker: the crawlers of OpenAI, Anthropic, Perplexity, Google, Apple, Amazon, Meta, ByteDance, Cohere and Common Crawl, each read against your robots.txt for the page you entered.
Why is my page blocked if robots.txt allows everything?
robots.txt is one gate. A noindex tag or header, a firewall or bot protection that answers crawlers with an error, or a canonical that points somewhere else will each keep a page out of AI answers even when robots.txt is open.
Does llms.txt help me show up in AI answers?
There is little evidence that answer engines read it today. It is cheap to publish and some agent and developer tools use it, so we note whether you have one, but it never counts as a fix.
How often should I run it?
After any release that touches templates, robots.txt, redirects or the CDN, and monthly otherwise. Rank Prompt runs the full site audit on a schedule and tells you when something breaks.
How do I see whether AI crawlers actually read this page?
This check reads the page’s rules, not its traffic. Your server’s access log has the visits: upload it to Rank Prompt and the pages table shows which AI crawlers fetched each page, how often and with which status. The AI crawler logs guide covers nginx, Apache, Cloudflare Logpush and CSV.
