What is Query fan-out?

Decomposition of one query into several subqueries

Query fan-out is the process by which an engine expands a complex question into smaller searches. Sources retrieved for those subqueries are later combined into an answer.

What Query fan-out means in GEO

In a RAG pipeline, publishing is not enough. A page must be discoverable, enter the candidate set and survive reranking.

Why it matters

Cover attributes, comparisons, constraints and use cases that may become independent subqueries.

What to check in practice

Identify the stage where the source disappears: access, initial retrieval, reranking, generator context or citation selection.

How it connects to other concepts

Query fan-out belongs to retrieval and rag. It is best analyzed alongside related terms because AI visibility depends on several stages and signals rather than one isolated optimization.

Common mistake

Blaming final copy when the document never reached the model that writes the answer.
