In traditional marketing, Share of Voice (SoV) measures how much of the conversation your brand owns compared to competitors. In the age of AI answers, the same idea applies — but the conversation is happening inside ChatGPT, Perplexity and Gemini.
AI Share of Voice is the proportion of answers — across the prompts that matter to your business — in which your brand shows up versus the competition.
Why it's the metric that matters
A single answer is a snapshot. Share of Voice is the trend. It tells you:
- Whether you're gaining or losing ground in AI answers over time.
- Which competitors are surging in your category.
- Where you're strong (and should defend) versus weak (and should invest).
How to measure it
- Define your prompt set. List the real questions buyers ask in your category — branded, commercial, comparison and problem-solving prompts.
- Run them on a schedule. Send each prompt to the AI engines you care about, consistently.
- Detect brand mentions. For every answer, record which brands are mentioned and cited — yours and competitors'.
- Compute the ratio. Your Share of Voice is your mentions divided by total brand mentions across the set.
Turning the number into action
SoV is only useful if it drives decisions:
- Defend your strengths. Where you lead, keep your content fresh and accurate so you stay the cited source.
- Attack your gaps. Where a competitor dominates, study what's being cited and publish something better.
- Catch surges early. A sudden competitor climb is an early warning — act before it compounds.
> What gets measured gets managed. Share of Voice turns the fuzzy question "how are we doing in AI?" into a number you can move.
AI Visibility Tracker computes Share of Voice automatically across your prompts and competitors, charts it over time, and alerts you when it shifts — so you always know where you stand.
