I built a free tool to check if your site is "readable" by ChatGPT/Perplexity (AEO/GEO audit) - sharing in case it's useful
Context: a client asked me why ChatGPT never mentions their brand, even when they're clearly the best fit for the query. I didn't have a great answer, so I dug in.
Turns out ranking well on Google doesn't mean much to how AI engines decide what to cite. They crawl differently and evaluate trust signals separately — schema, crawler access, author/org info, content structure. A page can rank fine on Google and still never get cited by ChatGPT or Perplexity.
So I built a checker: paste a URL, get a score out of 100 across 5 areas —
- Crawlable — robots.txt, AI crawler access (GPTBot, ClaudeBot, PerplexityBot, etc.), sitemap
- Citable — content depth, FAQ structure, freshness
- Structured — schema markup, heading hierarchy, alt text
- Authoritative — internal/external linking, entity schema, llms.txt
- Verifiable — author identity, About/Contact pages, E-E-A-T signals
It also tells you exactly what's failing and how to fix it, not just a score.
I'm still actively finding edge cases and fixing them, so if you run it and something looks wrong or missing, I'd genuinely appreciate the feedback — happy to fix it.
