What it is definition

Visits pages submitted as ChatGPT ads to check policy compliance and ad relevance; not used for model training.

OAI-AdsBot is operated by OpenAI and classified here as live retrieval. These agents fetch a single URL because a user asked about it. Disallowing one means the assistant answers from an older copy or from someone else's summary instead of the live page. Several are documented as not bound by robots.txt, because the request is user-initiated rather than a crawl.

Disallowing oai-adsbot stops the fetch that happens when a user asks OpenAI's AI products about one of your URLs. The answer still gets written, from an older copy or from a third party's description of the page, and you no longer control what it says.

Allow it
User-agent: oai-adsbot

Absent any rule, the agent is already allowed, so this group only matters when your * group disallows something. Naming the agent replaces the * group for it entirely, so repeat here every disallow you still want to apply to it.

Common questions answered

Does blocking OAI-AdsBot remove me from OpenAI's AI products?

Partly. OAI-AdsBot fetches a page only when a user asks about it, so disallowing it does not delist you from OpenAI's AI products. It does mean the answer is composed without your live page, from a stale copy or a third-party summary.

How do I verify OAI-AdsBot requests are genuine?

OpenAI publishes the address ranges its crawlers fetch from as JSON files linked from its bot documentation, one file per agent. Compare the source address of the request against the file for that agent. There is no reverse DNS name to check, so the address list is the only signal.
