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 the way their crawlers do, 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.
CrawlCheck is the verification layer for the agentic web. It measures what a site actually serves — fetched as GPTBot, ClaudeBot, PerplexityBot, Googlebot and eight 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.
GPTBot, ClaudeBot, PerplexityBot, Googlebot and eight 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.

Being readable beats being talked about.
A September 2026 study ran 37,927 AI agent sessions about 1,056 real businesses, each one a buyer’s question. When the agent could fetch and read the business’s own site, it did better on every measure. That reading is what CrawlCheck checks.
| 1.9× | as often clearly recommended when agents could read the site |
|---|---|
| 78% vs 56% | of answers built from the business’s own pages, readable site against the rest |
| 41% | more accurate answers when built from the site, same business and question |
| 7–10% | of the final answer came from what the model already knew; the rest was read live |
