GPTBot is OpenAI's training crawler. It gathers publicly available web data used to train future GPT models. It is a training crawler, not a search or answer crawler, so it has no direct role in what ChatGPT shows users in real time.
Blocking GPTBot is a content-licensing decision: it keeps your material out of the training corpus. Many publishers block it to protect proprietary content while leaving OpenAI's search crawlers allowed, so they still appear in ChatGPT answers.
How to check and control it
To check, look in your robots.txt for a rule targeting this user-agent. To allow or block it:
User-agent: GPTBot
Disallow: / # blocks it — remove or set "Allow: /" to permit

FAQ
Does blocking GPTBot remove me from ChatGPT?
No. GPTBot only feeds model training. ChatGPT's live search and citations rely on OAI-SearchBot and ChatGPT-User, which are separate user-agents. Blocking GPTBot opts you out of training but leaves your ChatGPT search visibility intact if those other crawlers remain allowed.
Is blocking GPTBot good for SEO?
It has no effect on Google or Bing rankings, since GPTBot is unrelated to traditional search indexing. The choice is purely about whether you want your content used to train OpenAI's models. SEO AEO Specialist can audit which AI crawlers you allow and diagnose the trade-offs.
