What is AI share of voice?
AI share of voice is the percentage of AI-generated answers in your category that mention or recommend your brand versus competitors, measured across a fixed set of buyer prompts and engines. Unlike social share of voice, it must be actively sampled — AI answers only exist when a question is asked — and it shifts with model and source updates.
Traditional share of voice counts published mentions across news and social media. AI share of voice has no feed to listen to: the 'content' is generated on demand, per question, per engine. Measuring it means defining a stable prompt set (the questions your buyers actually ask), running those prompts on every engine you care about, and scoring who gets mentioned, who gets recommended, and in what order.
Two design decisions matter. First, hold the prompt set constant — if the questions change every week, the trend line means nothing. Second, separate mention from recommendation: being listed fourth in a roundup is very different from being the engine's explicit pick, and only the latter reliably moves deals.
Because engines update models and retrieval sources continuously, AI share of voice moves without you doing anything. That is exactly why it is worth tracking: a drop on high-intent prompts is an early warning that a competitor's content or a stale source is displacing you in front of live buyers.
