How AI Search Works: Finding Brand Information

AI search tools find information in different ways. Google's AI search features retrieve pages from its Search index and may expand a question into related queries, while ChatGPT search can rewrite questions and use search providers to find relevant sources. This makes crawlability and indexation important for discovery through search, although the requirements depend on the product. Being indexed, retrieved or cited does not guarantee that your brand will be recommended.

Further questions and evidence

Does blocking GPTBot also block ChatGPT Search?

No. OpenAI documents separate controls for GPTBot, which crawls content that may be used for model training, and OAI-SearchBot, which is used for search. Blocking GPTBot alone does not block OAI-SearchBot.

This distinction applies to OpenAI. Allowing its search crawler does not guarantee that a page will appear or be recommended.
