OAI-SearchBot is OpenAI's search crawler. It fetches and indexes live web content so ChatGPT can surface and cite up-to-date sources when users ask questions. It is a search/answer crawler, not a training crawler, so it directly affects whether you appear in ChatGPT answers.
If you want to be cited in ChatGPT search, OAI-SearchBot must be allowed. Blocking it is one of the most common accidental reasons sites vanish from ChatGPT's cited sources.
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: OAI-SearchBot
Disallow: / # blocks it — remove or set "Allow: /" to permit

FAQ
What's the difference between OAI-SearchBot and GPTBot?
OAI-SearchBot powers ChatGPT's live search and citations, while GPTBot only collects data for model training. Blocking OAI-SearchBot removes you from ChatGPT answers; blocking GPTBot only opts you out of training. They are controlled by separate robots.txt rules.
Will blocking OAI-SearchBot hurt my visibility?
Yes, inside ChatGPT. If OAI-SearchBot cannot crawl your pages, ChatGPT search cannot index or cite them, so you lose that referral and answer-engine exposure. SEO AEO Specialist can diagnose whether you're accidentally blocking it and help you fix, not just monitor, the rule.
