Query fan-out
Definition
Query fan-out is when an AI search system breaks one question into several related sub-queries, runs them and combines the results into one answer.
Why it matters
It means a page can be used because it matches a sub-question, not only the visible one. Covering related questions thoroughly increases the chance of being drawn in.
Example
A question about the best laptop for students may fan out into battery life, price, weight and reviews.
