GPTBot Crawl Tester

Check which AI crawlers your robots.txt allows or blocks

What is the GPTBot Crawl Tester?

The gptbot crawl tester works like this: it reads a site's robots.txt and reports whether the major AI crawlers (GPTBot, ClaudeBot, Google-Extended, CCBot, PerplexityBot, Bytespider) are allowed or blocked. Everything happens on your device - the input never leaves your tab unless the tool clearly states it performs a server-side lookup.

How to use the GPTBot Crawl Tester

1. Enter the full URL, domain or content the tool asks for.
2. Run the check - fetch-based tools query the page server-side.
3. Read the findings as a list, not a single score.
4. Fix one issue at a time and re-run to verify.

Features

• Checks run server-side so protected pages can be read
• Results explain the rule or value behind every finding
• Copy and export options for every result list
• No account needed for any check

Common mistakes to avoid

• Auditing a staging or password-protected URL instead of production
• Fixing everything at once instead of one change plus re-test
• Treating any single score as a ranking promise

Examples

Privacy

The URL you check is fetched once so the tool can read pages that block cross-origin browser requests. No browsing history is stored, and nothing from your own device is transmitted.

Frequently asked questions

Should I block AI crawlers?

Trade-off: blocking removes your content from AI training but also from AI answer engines that cite sources - a growing referral channel. Most publishers currently allow answer-bots while deciding on training bots.

Is blocking GPTBot the same as blocking ChatGPT browsing?

No - GPTBot trains models; ChatGPT-User and OAI-SearchBot fetch pages when users ask. Each has its own rules.

Which AI crawlers are checked?

The major ones - GPTBot, ClaudeBot, Google-Extended, CCBot, PerplexityBot and Bytespider - each tested against the site's robots.txt the way that crawler would read it.

What does an allow or block verdict mean?

Allowed means the crawler may fetch the site's pages for training or search; blocked means robots.txt tells it not to - the verdict reflects the rules as written, including crawl-delay nuances.
