Best practices

Recommendations from official docs

GPTBot controls training, not ChatGPT search

OpenAI documents GPTBot for generative AI training data. Blocking GPTBot does not block OAI-SearchBot, which powers ChatGPT search citations.

Allow for maximum AI training inclusion

Publishers who want content considered for future OpenAI models should allow GPTBot on public pages. Review licensing and content policies before allowing.

Block to opt out of training

Disallow: / under User-agent: GPTBot opts your site out of future training crawls. Existing model knowledge is not removed — this affects future collection only.

Verify with official IP ranges

Validate real GPTBot traffic against openai.com/gptbot.json IP ranges at your firewall — do not rely on User-agent alone for security decisions.

How to fix

Step-by-step action plan

  1. 1 Read your robots.txt and locate the User-agent: GPTBot block (or add one).
  2. 2 To allow: use Allow: / or omit a Disallow for public paths.
  3. 3 To block training: add User-agent: GPTBot followed by Disallow: /.
  4. 4 Keep OAI-SearchBot allowed separately if you want ChatGPT search visibility.
  5. 5 Allow ~24 hours after robots.txt changes for OpenAI systems to refresh.
