Query Fan-Out
Query fan-out is a technique used by AI-powered search systems (including Google's AI Overviews and various AI assistants) where a single user question is broken down into multiple related sub-queries, each searched separately, with the results synthesized into one combined answer.

SEO Glossary

This matters for content strategy because a page doesn't need to answer an entire complex question in one place to be cited — it might get pulled in only for one specific sub-query within a larger fan-out, which means comprehensive, well-organized content that clearly answers several distinct sub-questions (each under its own heading) has more surface area to be selected for one or more of those fanned-out searches than a single, monolithic answer would. Understanding fan-out reinforces the same practical GEO advice that applies elsewhere: structure content with clear, distinct, answerable sections rather than one long undifferentiated block, since each well-defined section is effectively competing for its own separate retrieval opportunity within the fan-out process.
Example
A question like 'is SeoSorted better than Ahrefs for a small SaaS company' might fan out into separate sub-queries on pricing, feature comparison, and small-business fit — a comparison article with clearly separated sections for each has more chances to be selected across the fan-out than one undifferentiated block of text.
