An AEO checker scores how ready your site is to be cited by AI engines. Here is what an AEO score checker measures and how to read your result.
An AEO checker is a tool that scores how ready your website is to be cited by AI answer engines. It inspects the signals that determine AI citability — whether AI crawlers can reach your content, whether you have an llms.txt file, whether your pages are readable in plain HTML — and turns them into a single score, so a fuzzy question becomes a concrete number you can act on.
The term covers two related things. A technical AEO score checker measures whether your site is set up correctly for AI engines. A visibility-focused checker goes further and measures whether AI engines actually mention your brand. Both are useful, and they answer different questions.
Most sites were built for Google, not for AI engines, and the two have different requirements. A site can rank well in Google while quietly blocking the crawlers that feed AI answers or hiding its content behind JavaScript that AI bots do not execute. An AEO checker surfaces those gaps quickly.
Running one is the fastest way to find the obvious barriers. Before investing in content, it is worth confirming that AI engines can actually read your site at all — a blocked bot or a missing llms.txt file can undo a lot of good content work.
A technical AEO score checker typically looks at a handful of signals.
Each of these is binary or close to it, which is why they combine cleanly into a score. A low result usually points to one or two specific, fixable barriers rather than a vague deficiency.
Scores are commonly expressed on a 0 to 100 scale, where higher means your site is better prepared for AI citability. There is no universal passing mark, but the value is less in the number itself and more in what it isolates — a low crawler-access sub-score, for instance, tells you exactly what to fix first.
Treat the score as a diagnostic, not a grade. The point is to convert "is my site AI-ready?" into a short, prioritized checklist.
It is worth being clear about what a technical AEO checker can and cannot tell you. A high technical score means AI engines can reach and read your content — the door is open. It does not mean they are walking through it and recommending you. Those are two different questions, and confusing them leads to a false sense of security.
Think of the technical score as a prerequisite. If your crawler access is blocked or your content is invisible in raw HTML, no amount of good writing will get you cited, so fixing those barriers comes first. But once the fundamentals pass, the meaningful question shifts from "can engines read me?" to "are engines citing me?" — and only a visibility measurement answers that.
The practical takeaway is to use a technical checker to clear the barriers, then move to citation tracking to measure results. Stopping at the technical score is like confirming your store is unlocked without ever checking whether anyone came in.
A technical checker tells you whether your setup is sound; it does not tell you whether engines are recommending you. That is the difference between readiness and results, and closing it requires measuring your actual citation rate.
