Is ChatGPT Blocked From Crawling My Website?

ChatGPT relies on two user-agents—OAI-SearchBot (for live search citations) and GPTBot (for model grounding)—to read your site. If your CDN, WAF, or robots.txt returns HTTP 403 or Disallow to these bots while allowing Googlebot, your pages will be omitted from ChatGPT Search answers.

Why This Matters for Search & AI Visibility

Over 30% of commercial software and B2B discovery queries now occur inside AI answer engines. Many security firewalls block non-Google bot signatures by default without the site owner realizing it.

How to Fix It Permanently

Ensure your edge firewall (Cloudflare, AWS WAF, Fastly) allows verified OpenAI IP ranges and that your robots.txt explicitly permits OAI-SearchBot and GPTBot on public marketing and documentation paths.
