Should I Block GPTBot?

By Andrej Ruckij · June 16, 2026

TL;DR: Block GPTBot if you don’t want your content used to train OpenAI’s models for free — training gives no citation or traffic back. Importantly, blocking GPTBot does not remove you from ChatGPT search; that’s governed by a separate bot (OAI-SearchBot) you can keep allowed.

The direct answer

For most sites, blocking GPTBot is reasonable: it’s a training crawler, so it takes your content to improve OpenAI’s models and returns nothing — no link, no referral traffic. The key thing to understand is that GPTBot is not the bot that makes you visible in ChatGPT. So you can block training while staying fully present in AI search:

  • Block GPTBot → opt out of training.
  • Allow OAI-SearchBot → stay citable in ChatGPT search.
  • Allow ChatGPT-User → don’t block real users who open your page via ChatGPT.

Why people ask this

The fear is “if I block OpenAI, I’ll vanish from ChatGPT.” That conflates two different bots. Blocking GPTBot only opts you out of training; your visibility in ChatGPT’s answers depends on the search crawler, which is separate. The genuine tradeoff is narrower than it sounds — and it only gets murky for vendors that don’t separate their training and search bots (OpenAI does separate them cleanly).

How to apply it

Add this to robots.txt:

User-agent: GPTBot
Disallow: /

User-agent: OAI-SearchBot
Allow: /
User-agent: ChatGPT-User
Allow: /

GPTBot respects robots.txt, so this is honored. Two caveats: (1) it stops future crawls only — content already in past training data stays; (2) robots.txt won’t stop non-compliant scrapers, which need a firewall (robots-txt-vs-waf-ai-bots).

Key takeaways

  • Blocking GPTBot opts you out of OpenAI training, which gives nothing back.
  • It does not affect ChatGPT search visibility — allow OAI-SearchBot for that.
  • Never block ChatGPT-User — those are real visitors.
