What is Query Fan-Out?
Query fan-out is how AI search systems research a question. Instead of running your query once, the system generates many related sub-queries, searches them all in parallel, and builds its answer from the combined results. Google describes AI Mode working this way.
Why it changes content strategy
If one question becomes twenty sub-queries, your page competes in twenty retrievals, not one. Sites that cover a topic's full question space (the comparisons, the pricing questions, the how-tos, the edge cases) get more chances to be pulled into the final answer than a single optimized page ever could.
- Cover related questions as separate, clearly-scoped pages or sections
- Answer each question directly in the first paragraph
- Use headings that match how people actually phrase sub-questions
