Share of Answer
The proportion of a single AI answer's content devoted to describing a brand, relative to the content devoted to every other brand named in that same answer.
How it differs from share of voice
Share of voice aggregates mention counts across an entire tracked prompt set. Share of answer looks inside one response and measures depth of coverage — a brand mentioned once in a single throwaway clause and a brand given its own descriptive paragraph both count as one mention, but they have very different shares of that answer.
Why it matters
A brand can technically be included in an answer and still get a thin, one-line treatment while a competitor gets several sentences of explanation. Share of answer catches that difference, which raw inclusion or mention counts can't.
