Most websites don't know whether ChatGPT, Claude or Gemini can find them. We check. Free. No signup. We test against Common Crawl - the dataset most large language models are trained on - and give you a score plus actionable fixes.
Hundreds of millions of queries that used to go to Google now go to ChatGPT, Claude, Gemini and Perplexity. If your domain isn't in their training data or live retrieval, you're not in the answer.
AI chat is becoming the primary research interface for buyers, journalists, students and decision-makers. Being absent from AI answers is invisible in 2026.
Most LLMs are trained on Common Crawl, a public web archive. If CCBot can't reach your site, the AI you care about probably doesn't know what you do.
Most low AI visibility scores come from three or four technical issues that take an afternoon to fix - robots.txt, schema, content depth, internal linking.
Honest, technical, opinionated. Written by people who actually do this work.
Common Crawl is the public web archive that trained most large language models. If your site isn't in it, ChatGPT, Claude and Gemini probably don't know you exist.
