What Is AI Share of Voice?
AI share of voice is the percentage of brand mentions in a tracked set of AI answers that belong to one brand rather than its competitors. If engines name brands 1,000 times across your prompts and 342 of those mentions are yours, your AI share of voice is 34.2%.
To measure it against the competitors your own prompts surface, see SeenMeter’s AI share of voice tracking.
Share of voice is a relative measure, and that is the point. Your own mention rate can climb while your share falls — because a competitor is climbing faster. Absolute numbers tell you your lap time; share of voice tells you the race.
Measured honestly, it comes from the same stored answers as everything else: count every brand named across your prompt set, engines, and time window, then divide. The competitor list is not the one on your pitch deck — it emerges from the answers themselves, which is often the first surprise. Each percentage should open back to the answers that produced it.
