Fan-Out Query

A fan-out query is what happens under the hood of modern AI search. You ask one question. The engine — Google's AI Mode is the clearest example — decomposes it into a fan of related sub-questions, runs each as its own search, and stitches the results into a single synthesized answer.

The implication is a structural shift in how visibility works. Your brand no longer needs to rank for one keyword — it needs to be retrievable across the whole fan of sub-queries the engine generates. Broader coverage, more entry points, more chances to be cited.

This is why narrow keyword targeting is losing to entity authority and topical depth. Fan-out rewards brands that own the full conversation around a topic — the core of Generative Engine Optimization (GEO).
