Query Fan-out
Also known as: クエリファンアウト / クエリ分解
A query-processing technique used by Google AI Mode that expands a single user query into multiple parallel sub-queries, then synthesizes the results into a comprehensive answer.
Overview
Query Fan-out decomposes complex queries — such as 'compare X and Y' — into several specialized sub-queries that run in parallel. Synthesizing those results produces a deeper answer than any single query could yield.
Content Strategy Implications
Comprehensively covering the topics corresponding to likely sub-queries increases the probability of being cited in AI Mode. See Google's official AI Optimization Guide analysis for strategic guidance.
