GEO glossary
Share of voice (in AI answers)
Share of voice in AI answers is the proportion of relevant AI-generated answers in which a brand is named or cited, relative to its competitors, across a defined set of prompts and engines. It is the headline metric of GEO.
It is calculated across a fixed prompt set and chosen engines, often weighted by how prominently the brand appears. Tracking it over time shows whether GEO work is landing.
