Can AI read your site?
CrawlCheck is a free check that shows what ChatGPT, Google and other AI assistants can read on your website. We visit your site from our own network using their crawlers’ names, then tell you in plain words what they could read, what they could not, and the one thing to fix first.
We visit your site as twelve crawlers and tell you what each one got.
GPTBot, ClaudeBot, PerplexityBot, Googlebot and 9 more, from our own network. Then your robots.txt, your machine files and what you have told agents they may do. The answer is graded by published rules and signed, so anyone can check it offline.
The full definition
CrawlCheck is the verification layer for the agentic web. It measures what a site actually serves — fetched as GPTBot, ClaudeBot, PerplexityBot, Googlebot and nine other crawler identities, plus its machine files, crawl policy, declared rights and capabilities — decides findings by published rules, and signs the answer so an agent can verify it offline before it reads, cites, connects or acts. Site owners get the same measurement as a free A–F audit with every defect named.

Being readable beats being talked about.
In 37,927 AI agent sessions about 1,056 real businesses, agents did better on every measure when they could read the business’s own site.
| 1.9× | as often clearly recommended |
|---|---|
| 78% vs 56% | of answers built from the business’s own pages |
| 41% | more accurate answers |
| 7–10% | of the answer came from the model’s memory |
