AEO checker: is your site ready for AI answers?
AEO (answer engine optimization) is the work of making a page fetchable, parsable and citable by AI answers. This free AEO checker tests that access and readiness layer — not how often an assistant mentions your brand.
Reads the public surface only — no JavaScript, no login.
Checks site-wide files at the domain root — any page URL on the domain gives the same result.

What the AEO checker verifies
Before an AI answer can cite a page, the crawler has to fetch it, parse it and find the machine-readable context around it. The checker scans the same files and headers the audit uses:
- robots.txt — whether the crawler may fetch the page at all.
- llms.txt — whether the citable pages are declared with live links.
- Content signals and bot identity — whether training and input use are declared.
- Agent discovery — Link headers, API catalog, auth.md, A2A, MCP and OAuth metadata.
What it does not do
It does not query ChatGPT or Google AI, count brand mentions, or produce a Share of Model number. Those are separate measurement products; this page only checks whether the machine-readable access layer is ready.
How to improve AEO
- Fix access first: robots.txt must allow the crawler, and llms.txt must be reachable.
- Declare AI-use preferences and a bot identity directory if you want to be trusted.
- Publish agent discovery files, then re-run the scan above after each deploy.
Frequently asked questions
What does AEO mean?
AEO stands for answer engine optimization: preparing a page so an AI answer can fetch it, parse its content, trust the source and cite it. In practice that means crawl access, llms.txt, content signals, bot identity and agent discovery — the same layer this checker scans.
How do I track AEO?
A single scan is a snapshot; tracking means re-running the same checks after each deploy and watching what AI crawlers actually fetch. This checker gives the snapshot. The console adds scheduled AI Overview citation samples and crawler telemetry when you want a trend instead of a point-in-time result.
What is an AI visibility checker?
It checks whether AI crawlers can reach, parse and trust your pages: robots.txt and llms.txt access, content signals, bot identity, Markdown negotiation and agent discovery files. Those are the inputs a citation depends on.
Is this an AEO checker or a rank tracker?
It is an AEO readiness checker. It does not monitor how often ChatGPT, Google AI or other assistants mention your brand, and it does not sell a Share of Model score.
What does it check?
AI crawler access (robots.txt, llms.txt, content signals, bot identity) plus agent discovery (Link headers, API catalog, auth.md, A2A, MCP and OAuth metadata). Every verdict names the fix.
Is this one of the answer engine optimization tools I need?
Yes for the readiness layer: it covers crawl access, content signals and agent discovery. It does not track brand mentions, so pair it with a separate visibility measurement tool if you need Share of Model.
