Query Fan-Out

Query fan-out is a technique used by AI engines where a complex query is automatically broken down into several sub-queries to find more precise and complete answers.

How it works

When a user asks "What is the best GEO agency in Belgium for a B2B company?", the AI can break this query down into: "GEO agencies Belgium", "GEO for B2B", "GEO agency reviews", etc. Each sub-query is processed independently via RAG, and the results are synthesized.

Impact on GEO

Query fan-out means that a single user query can interrogate many pages. Your content strategy must cover every possible angle: sector pages (GEO B2B), geographic pages (GEO Agency Belgium), and specific thematic pages. It's the content architecture that determines your coverage against query fan-out.
