Also called: AI share of voice, answer share of voice
Share of voice in AI answers is the proportion of relevant AI-engine answers in which a brand appears (or is recommended) relative to its competitors — a comparative measure of standing in the answer layer.
Share of voice measures how much of the answer space a brand occupies compared with its competitors for a defined set of buyer questions. Rather than an absolute presence rate alone, it frames the question competitively: when buyers ask, how often are you named versus the alternatives?
In the AI-answer context it must be measured the same disciplined way as any visibility metric — sampled across many runs, per engine, with intervals — because the comparison is only meaningful if each brand's rate is itself trustworthy. A comparative chart built on single-shot scores compounds the noise.
Share of voice is useful because it turns an abstract score into a standing your buyers experience: it is the difference between being one of several brands the engine mentions and being the one it recommends.
