What is Query Fanout in AI Search?
Last updated: August 21, 2025
AI Search Dynamics

Query Fanout refers to the process where Large Language Models (LLMs) generate multiple related queries based on an initial user prompt to gather more comprehensive information. For example, if a user asks about 'the latest Google patent discussed by SEOs,' an LLM might perform additional web searches like 'latest Google patent discussed by SEOs patent 2025 SEO forum' or 'latest Google patent SEOs 2025 discussed.' Understanding these fanout patterns allows content creators to optimize for these expanded queries, increasing the chances of their content being retrieved and used by AI models.
