As AI-powered engines like ChatGPT, Claude, Perplexity, and Google Gemini handle more user search queries, getting your content cited by AI models requires proper crawler access.
Key AI Crawlers & What They Do:
- GPTBot (OpenAI): Used to expand OpenAI's AI training models. Blocking GPTBot prevents your site from training future GPT models.
- ChatGPT-User (OpenAI): Used when a user explicitly asks ChatGPT to browse a live website URL. Blocking this prevents live browsing citations.
- ClaudeBot (Anthropic): Powers Anthropic's Claude AI model training and web citations.
- PerplexityBot (Perplexity AI): Powers live answer engines in Perplexity. Blocking this excludes your site from Perplexity citations.
- Google-Extended (Google): Controls whether Google can use your content to train Gemini AI and Vertex AI models.

What is the difference between GPTBot and ChatGPT-User?
GPTBot is OpenAI's automatic web crawler used to fetch data for training future AI models. ChatGPT-User is triggered in real-time when a user explicitly asks ChatGPT to visit and analyze a live web URL.
Should I block AI crawlers in my robots.txt file?
If you want your website content to be discovered, cited, and recommended in AI Search Engines like ChatGPT, Perplexity, and Google AI Overviews, you should allow AI crawlers. Blocking them excludes your site from Generative Engine Optimization (GEO).
How do I unblock GPTBot and ClaudeBot?
Remove any "Disallow: /" directives for User-agent: GPTBot or User-agent: ClaudeBot in your website's robots.txt file, or explicitly declare "Allow: /" for them.
