What is GPTBot Checker?
GPTBot is OpenAI's web crawler. If it cannot reach your content, ChatGPT will not cite you — no matter how good your content is. The GPTBot Checker fetches your robots.txt, isolates the GPTBot-specific rules, estimates your last-crawl window based on public logs, and tells you exactly what to fix if you are blocked.
How it works
Enter your URL
We fetch your robots.txt and look for User-agent: GPTBot rules. If none exist, GPTBot is allowed by default.
Verify crawlability
We check for path-level Disallow rules, edge-level blocks (Cloudflare, WP Engine), and the presence of a recent GPTBot hit in your logs (if you connect them).
Get your GPTBot status
Receive a clear Allowed / Blocked verdict, the responsible rule, and a copy-paste fix to allow GPTBot without opening the door to scrapers.
