AI Share of Voice

AI Share of Voice is how much of your category's AI attention you capture when buyers ask AI assistants for a recommendation. Where AI Visibility is your absolute standing, AI Share of Voice is the competitive, zero-sum view.

Quick answer: AI Share of Voice = your weighted AI mentions ÷ all weighted AI mentions in the category. As one brand gains share, the others lose it.

Why AI Share of Voice matters

An AI assistant rarely lists every vendor — it names a handful. That makes the category zero-sum: every recommendation that goes to a competitor is one that didn't go to you. AI Share of Voice tells you whether you're winning the conversation relative to the brands you compete with, not just whether your own visibility is rising.

How AI Share of Voice is calculated

CiteMatrix.ai runs real buyer-intent prompts across ChatGPT, Claude, Gemini and Perplexity, weights each mention by prominence, then divides your weighted mentions by the total for all companies in the category. A share of 20% means one in five weighted AI mentions in that category point to you.

Growing your AI Share of Voice

Because share is zero-sum, growing it means being named where competitors currently are — in the comparison content, category pages, reviews and documentation AI assistants synthesize. A CiteMatrix.ai audit shows exactly where competitors out-appear you.
