Frequently Asked Questions
Should I block AI crawlers in robots.txt?
Blocking AI crawlers prevents your content from appearing in AI search results. Unless you have specific reasons (copyright, bandwidth), it's generally better to allow AI crawlers to increase your AI visibility.
What is GPTBot?
GPTBot is OpenAI's web crawler used to train and improve ChatGPT. If blocked, your content won't be used in ChatGPT's training data or cited in its responses.
Does robots.txt affect all AI platforms?
