Share of voice
Your brand's mentions as a share of all brand mentions in the same set of answers. It shows whether competitors are gaining on you, which mention rate alone does not.
Also called SOV, AI share of voice · Sources checked 15 November 2026
Say ten AI answers to your buyer questions name 40 businesses between them, and you are named in 6. Your share of voice is 6 of 40, or 15%. Mention rate tells you how often you appear. Share of voice tells you how much of the conversation you hold against everyone else named.
It moves for reasons you did not cause. A model update can reshuffle every answer in a category at once. Judge it over several weeks, and look at which competitors gained before deciding what changed.
