What is Query fan-out?
Query fan-out is when an answer engine expands one user question into several sub-queries, retrieves sources for each, and synthesizes them into a single answer. It means your page can be cited for a sub-question you didn't obviously target — so covering a topic thoroughly widens your citation surface.
