What is Query fan-out?
Query fan-out is when an AI system turns one user question into several related search queries, runs them in parallel and combines the results into one answer. It means a brand can be retrieved through sub-questions the user never typed, such as price, alternatives or reviews.
What it means for content
A single prompt like "best accounting software for freelancers" may expand into queries about pricing, invoicing features, tax rules and reviews. Pages that answer these narrower questions have more chances to be retrieved.
How to use it
Map the sub-questions around each buyer question and make sure you have a clear, early answer for each. Include them in your tracked prompts, because they shape which sources are cited.
