Agent Commerce
Agent Share of Voice
The percentage of relevant AI agent conversations in your category where your brand is mentioned or recommended, compared to competitors. If agents mention your brand in 22 out of 100 'best moisturizer' queries, your agent share of voice is 22%. Unlike traditional share of voice (measured by ad spend or media mentions), agent share of voice is earned through product quality, data structure, and brand authority — not bought through media budgets.
Why it matters
Mention rate tells you whether you appear. Share of voice tells you whether you appear instead of a competitor, which is the number that moves when you improve product data.
In practice
Record every brand named in each probe response, not just yours. The denominator is total brand mentions across the query set; your share is your count over that total.
