How to measure AI share of voice: a step-by-step method
AI share of voice is the proportion of relevant AI answers in which your brand appears, compared with competitors. Measure it by running a fixed set of buyer prompts several times on each platform, recording which brands are mentioned, recommended and cited, and dividing your appearances by the total appearances of all tracked brands. Report mention, recommendation and citation share separately, with the sample size.
