What OAI-SearchBot does

OAI-SearchBot reads pages so ChatGPT can show them in its search features. In OpenAI’s words, it “is used to surface websites in search results in ChatGPT’s search features.”

If you want ChatGPT to be able to cite and link to your site when people ask questions, this is the bot that has to be let in. OpenAI itself recommends allowing it.

Should you allow it?

Allow it. For almost any business that wants to be found through ChatGPT, blocking OAI-SearchBot works against you.

What blocking it changes: Your pages drop out of ChatGPT’s search results over the following day or so. ChatGPT can still mention you from what it already knows, but it can’t link to your current pages.

Allow or block OAI-SearchBot in robots.txt

You control it through robots.txt. OpenAI notes it can take about 24 hours after you change robots.txt for its systems to adjust.

To allow it

User-agent: OAI-SearchBot
Allow: /

To block it

User-agent: OAI-SearchBot
Disallow: /

robots.txt lets every bot in by default, so you only need the allow lines if another rule in your file would otherwise block it. Our robots.txt guide explains how rules for different bots combine.
