Query fan-out

Google's guide to its generative AI features defines query fan-out as a set of concurrent, related queries generated by the model to fetch more relevant results. A buyer who types "best ball valve manufacturer for a water treatment plant" may set off separate searches for pressure ratings, materials, approvals and suppliers in a region, and AI Mode or AI Overviews then draws on pages that answer any of those.

For a factory website this means a page can be cited for a question the buyer never typed. A product page that states sizes, pressure ratings, body materials and the industries served has more chances to match one of the fanned-out searches than a page that says "quality valves for all industries". Google is also clear that this is no reason to create a separate page for every sub-question; one full page per product serves both the buyer and the search.
