Query fan-out is what happens between your prompt and the AI's answer: the assistant silently expands one question into several background search queries, retrieves sources for each, then synthesizes the result.

Why it matters for marketers

You're not optimizing for one query, you're optimizing for the fan-out set. A prompt like "best Reddit marketing tool" may fan out into "Reddit marketing tools comparison", "Reddit automation ban risk", "Readyt reviews". Each fanned-out query has its own winning sources.

How to exploit it

Map the fan-outs for your money prompts (ask the assistant to show its searches, or use a tracking tool), then make sure you're present in the top sources for each sub-query, not just the head term.
