Free AI visibility & AEO readiness checker
AI assistants like ChatGPT, Perplexity, Claude and Google’s AI Overviews are becoming how people find businesses — but they can only recommend pages they can crawl, understand and trust. This free tool — built by a Singapore AEO agency — fetches any public URL and scores it out of 100 across the signals that decide whether an AI can cite it: AI-crawler access, structured data, answer-friendly structure, content depth and trust signals. You get a prioritised list of fixes. No signup, and we don’t store the pages we check.
What the score measures
Unlike a classic SEO audit, this checks the things AI models care about, grouped into four areas:
- AI crawler access — whether your
robots.txtactually lets the AI crawlers in (OAI-SearchBot for ChatGPT, Google-Extended for AI Overviews, PerplexityBot, ClaudeBot, GPTBot), plus indexability and an optionalllms.txt. Block these and you’re invisible to AI no matter how good your content is. - Structure & schema — JSON-LD structured data, a clean heading hierarchy, and scannable lists or tables that models can lift and attribute.
- Content & metadata — a strong title and meta description, enough depth to be a real source, and Open Graph tags.
- Trust & freshness — HTTPS, a named author, visible dates, a canonical URL and entity (Organization/Person) schema — the E-E-A-T signals AI weighs when choosing whom to cite.
Why AI crawler access is the make-or-break signal
Many sites unknowingly block the very bots that power AI citations. A single Disallow: / for GPTBot or Google-Extended in your robots.txt means ChatGPT or Google’s AI Overviews can’t read your content — so you’ll never be quoted, however authoritative you are. This checker inspects your robots.txt for each major AI crawler and flags any that are blocked. If you want to keep out data-harvesting scrapers without shutting out the citation bots, our AI crawler & llms.txt generator builds the right rules.
From checked to cited
A high score means AI can find, parse and trust your page — the prerequisites for being recommended. Turning that into actual citations is the work of answer engine optimisation (AEO) and generative engine optimisation (GEO): structuring content as clear, direct answers, building topical authority, and earning the mentions and reviews that teach AI you’re the trusted choice. Run the check, fix the flagged items, then re-run it to confirm — and pair it with our readability checker and schema generator.
Frequently asked questions
How does the checker work?
It fetches the URL you enter (server-side, so there are no browser restrictions), reads the page’s HTML, robots.txt and llms.txt, and scores the AI-visibility signals. It doesn’t use any AI API or store your page — it’s a fast, transparent, rules-based audit.
Does a high score guarantee AI will cite me?
No — it means AI can crawl, understand and trust your page, which is necessary but not sufficient. Actual citations also depend on topical authority, relevance to the query, and your reputation across the web. Think of the score as removing the technical barriers to being cited.
Which AI crawlers does it check?
The major ones behind AI answers and citations: OAI-SearchBot (ChatGPT), Google-Extended (Google AI Overviews and Gemini), PerplexityBot, ClaudeBot and GPTBot. Blocking any of these limits your reach in that assistant.
Can I check a competitor’s site?
Yes — it works on any public URL, so you can benchmark your AI visibility against competitors and see exactly where you can outrank them for AI citations.
