In one sentence GPTBot is OpenAI's web crawler, controllable through robots.txt, and documented as being used to gather training data.

It's documented as collecting data used to improve models. OAI-SearchBot is separate and serves search and citation, while ChatGPT-User handles fetches triggered directly by a user's request. The distinction matters commercially: you can allow search retrieval while disallowing training crawls, because they're controlled independently in robots.txt. ## Why it matters for AI search Blocking GPTBot is one of the most common unintentional AI visibility failures we find. It's often added years ago as a blanket AI-crawler rule, or by a security tool nobody associated with marketing. Whether to allow it is a genuine business decision rather than a technical default — but it should be a decision, not an inheritance. ## See it in action Three OpenAI agents, three different jobs. Here's what each one is for. ### OpenAI user agents robots.txt control $ ron crawl --agents all GPTBot — training datawaiting OAI-SearchBot — search & citationwaiting ChatGPT-User — user-triggered fetchwaiting Current site configwaiting #### Allowing search while disallowing training is a valid position. Many publishers take exactly this route: opt out of training, stay eligible for citation. Most brands selling a product benefit from allowing all three. ## How to get it right ### Configuring OpenAI crawlers - Check robots.txt for all three agents rather than assuming one rule covers them - Check your WAF and bot-management tool separately — they block by default more often than robots.txt does - Decide training and search access independently; they're different commercial questions - Verify with an actual fetch as the user agent, not just by reading the file - Re-check after deploys; security rule changes reintroduce blocks silently ## Common questions Should we allow GPTBot? It's a business decision. Allowing it is a precondition for being cited when ChatGPT searches. Blocking protects content from being used for training without compensation. Most brands selling a product or service benefit from being findable. Publishers monetising content directly have a stronger case for restricting. Does blocking GPTBot remove us from ChatGPT? Not entirely. GPTBot governs training crawls; OAI-SearchBot governs search retrieval. Blocking only GPTBot leaves you eligible for citation when ChatGPT searches. Blocking both removes you from the retrieval pathway completely. How do I check if we're blocking it? Read your robots.txt for a GPTBot user-agent block, then fetch a page with the GPTBot user-agent string and check the status code and response size. A 403, a challenge page, or a suspiciously small response all indicate a block. ## Related concepts These come up alongside GPTBot constantly.
