How to Check if GPTBot Is Blocked on Your Site
Many websites inadvertently block AI crawlers like GPTBot without knowing it. This guide shows you how to verify AI crawler access using Glippy and how to fix any blocking issues in your robots.txt.
Why Check for GPTBot Blocking?
If GPTBot is blocked in your robots.txt, your content cannot appear in ChatGPT search results. Similarly, blocking ClaudeBot, Google-Extended, or PerplexityBot prevents your content from being cited by their respective AI systems. Many hosting platforms and CMS plugins add these blocks by default.

- Install the Glippy Chrome Extension
- Navigate to any page on your website
- Click Glippy to run a scan
- Check the Machine Readability category for bot blocking results
Glippy checks for all major AI crawlers including GPTBot, ClaudeBot, and Google-Extended, as well as PerplexityBot, Bytespider, CCBot, and others.
How to Fix GPTBot Blocking
If Glippy detects blocking, check your robots.txt file for entries like:
User-agent: GPTBotfollowed byDisallow: /User-agent: ClaudeBotfollowed byDisallow: /- Wildcard rules that inadvertently catch AI crawlers
