Share of Voice in AI

Share of voice in AI is the proportion of relevant AI answers that mention or cite your brand, measured across a defined set of prompts your buyers are likely to ask. If you run fifty buying-intent questions through ChatGPT, Perplexity and Google's AI Overviews and your brand appears in twelve of the answers, that's your AI share of voice for those prompts, and you can track it against competitors.

Why it matters to a founder: it turns the fuzzy question "are we visible in AI?" into a number you can move and benchmark. Rankings told you where you stood on a results page; AI share of voice tells you how often the machine recommends you when it matters. You measure it by building a prompt set tied to your category and funnel, running it on a cadence, and logging who gets cited. The gaps, prompts where competitors appear and you don't, become a concrete content and authority roadmap rather than a guess.
