Is your homepage ready for answer engines?
Enter a domain. This checker fetches your homepage, robots.txt, and llms.txt and scores the on-page signals AI answer engines depend on.
Why AEO matters
Answer engines can only cite what they can use
Answer Engine Optimization is making your site usable by AI answer engines: they have to reach it (crawler access), read it (server-rendered content), understand it (clear headings and structured data), and navigate it (llms.txt). Miss one and your content can't be surfaced or cited.
This checker audits those on-page fundamentals in one pass, so you can see and fix the gaps before you worry about authority and content.
What a weak AEO foundation costs you
- AI crawlers are blocked or read an empty page
- Assistants can't tell what your page is about
- No structured data to ground answers in
- Competitors with a clean setup get cited instead

What does the AEO checker do?
It audits your homepage for the on-page fundamentals of answer-engine optimization — whether AI crawlers are allowed, whether your content is server-rendered, whether you have a title, meta description, and clear headings, whether you use structured data, and whether you publish an llms.txt — and rolls them into one readiness score.
What is AEO?
AEO (Answer Engine Optimization) is optimizing your site so AI answer engines — ChatGPT, Perplexity, Gemini, Google AI — can find, read, understand, and cite your content. It overlaps with SEO but focuses on being usable by AI answers, not just ranking in blue links.
What does it actually check?
It fetches three things: your homepage HTML (read without JavaScript, like an AI crawler), your robots.txt (to see if AI crawlers are blocked), and your llms.txt (if present). Then it scores the on-page signals that determine whether AI can use your page.
How is the score calculated?
The score is a simple, transparent average of the individual checks — each pass, improve, or fix. It's deterministic: the same page always gets the same score. It reflects on-page readiness, not whether you're actually being cited.
Does it check my whole site?
It checks your homepage. That's the most representative page for site-wide signals like crawler access, rendering, structured data, and llms.txt. For page-by-page depth, the full AEOMaster audit goes further.
Does a good score mean AI will cite me?
No. A strong on-page foundation makes it possible for AI to use your content, but whether AI answers actually mention and cite you depends on your authority, evidence, and content — which is what the full AEOMaster audit measures.
Beyond this tool
This checker scores your on-page AEO foundation. AEOMaster turns that into a full one-time audit of whether AI answers actually mention and cite you — with prioritized fixes.
Prompt-level results across ChatGPT, Claude, Perplexity, Gemini, and Google AI — not just on-page signals.
The sources AI answers cite, and the pages and citations you are missing.
Every finding ranked by expected impact and effort, so you know what to fix first.
Each issue comes with the why, the steps, and an example you can act on.
Re-run it after you ship fixes to confirm your readiness and visibility improved.
From on-page ready to AI citations
AEOMaster turns this on-page audit into a one-time AI visibility report: prompt-level findings, citation gaps, competitor context, and prioritized fixes you can re-run after each change.
