Full definition
Answer share operationalizes “how much of the AI answer space do we occupy?” for a defined prompt set and model mix. Teams may weight mentions by position (first named vs buried) or split share into recommendation share versus citation share.
It is closely related to share of voice and share of model; naming conventions vary by team. What matters is a written definition, stable sampling, and confidence that non-determinism is handled with repeats.
Use answer share as a core GEO KPI alongside traffic and conversion proxies. See Citation Rate, Share of Model, and AI Visibility.
