Share of Voice (SOV)
In one sentence
The percentage of brand mentions relative to total mentions of all peer brands across the same set of questions or within the same channel.
In AI search, you can track how often your brand and competitors are mentioned across a set of answers to evaluate your visibility gap against competitors.
Share of voice only measures mention volume; it must be evaluated alongside whether the descriptions are positive and accurate.
Example
Across answers to 30 questions, peer brands were mentioned 60 times in total, with your brand mentioned 9 times, representing a 15% share of voice.
