AI share of voice
AI share of voice measures how often a brand or domain is cited in assistant responses — ChatGPT, Perplexity, Gemini, AI Overviews — across a defined basket of target queries.
In practice
The measurement is becoming systematic: posing the same questions to the same assistants on a regular schedule, logging citations and links, and tracking the trend over time. Since clicks are invisible inside these interfaces, this share of voice becomes the modern equivalent of a rank position. We track it monthly across the strategic queries of each brand in the group.
