Definition
Share of answer measures how much of an AI response is devoted to a brand, source, or concept.
Expanded definition
Share of answer looks beyond whether a brand appeared. It considers prominence, depth, and whether the mention carried useful substance compared with competitors or alternatives. As a metric, share of answer should be read as a diagnostic signal rather than a standalone KPI. The next step is to connect the number to a specific answer pattern, source issue, buyer risk, or content decision.
Why it matters
A passing mention and a detailed recommendation are not equal. Share of answer helps teams separate presence from meaningful presence.
Example
An answer names five vendors, but spends three sentences explaining one competitor and only lists the brand once.
Common mistake
Treating every mention as equal regardless of prominence or usefulness.
Diagnostic question
Does the brand receive enough explanation for a buyer to understand why it belongs in the answer?
