OAI-SearchBot

OAI-SearchBot is a bot operated by OpenAI that indexes pages so an AI answer engine can cite them. Crawls sites to surface as results in SearchGPT. It honours robots.txt, and a request claiming to be OAI-SearchBot can be checked against a published IP range file.

robots.txt

Allow or block OAI-SearchBot

Paste one of these into the robots.txt file at the root of your domain. Rules are per token, so a block on one crawler leaves every other bot untouched.

Block OAI-SearchBot
User-agent: OAI-SearchBot
Disallow: /

Blocks every path for this crawler only.

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

Explicit allow. Useful when a wildcard rule above it would otherwise catch this crawler.

Allow, except the pages you never want quoted
User-agent: OAI-SearchBot
Allow: /
Disallow: /account/
Disallow: /checkout/
Disallow: /search

Edit the Disallow paths to match your own account, checkout and search URLs.

What blocking actually costs you

Blocking OAI-SearchBot takes the site out of the index behind its answers, so it stops being cited there. If referral traffic from AI answers matters to you, block the training crawler instead and leave this one alone.

Is that really OAI-SearchBot?

A user-agent header is a string the client chooses. Scrapers copy OAI-SearchBot precisely because site owners allow it. OpenAI publishes a separate range file for the search crawler. Blocking it removes the site from ChatGPT search results, which is a different decision from blocking training.

Paste the IP address from your access log below. You will see whether it belongs to a hosting provider, a residential proxy pool or a Tor exit, plus the ASN that announces it, which is what tells you whether the claim holds up.
