AI Share of Voice
Your brand's percentage of total AI mentions in a defined category, calculated against the combined mentions of all competitors across ChatGPT, Perplexity, Claude, Gemini, and Google AI Overviews.
What is AI Share of Voice?
AI share of voice (SOV) is your brand's percentage of total AI mentions in a defined category, measured against every competitor combined. If across 100 AI responses to category prompts your brand appears 28 times and competitors collectively appear 72 times, your AI share of voice is 28%. Unlike citation share, which measures absolute citation rate, SOV measures competitive position.
Why SOV Beats Absolute Citation Numbers
A 25% citation share looks impressive — until you discover three competitors hold 60% combined. SOV reframes the metric in competitive terms, surfacing whether you are growing share at competitors' expense or simply riding a category-wide tide. SOV is the metric that maps cleanly to revenue impact in mature categories.
How to Calculate AI Share of Voice
Define your competitor set (typically the 5–10 brands AI most often cites in your category). Track citations for your brand and every competitor across the same prompt set, on the same platforms, over the same time window. Sum total mentions, then divide your mentions by the sum. Recalculate weekly for headline metrics; monthly for executive reporting.
Benchmarks and Targets
In a category with 5 incumbents, even share is 20%. A challenger reaching 15% SOV in 6 months is a strong outcome. Category leaders often hold 30–40% SOV. Anything above 50% indicates near-monopoly position in AI recommendations and typically translates to dominant pipeline share.

Frequently Asked Questions
How is AI share of voice different from traditional SOV?
Traditional SOV measures ad impressions, social mentions, or organic search visibility against competitors. AI SOV measures citations and recommendations inside AI-generated answers — a fundamentally different surface that requires separate measurement infrastructure.
What is a good AI share of voice?
It depends on competitor density. In a category with 5 active competitors, 20–25% SOV is solid; 35%+ indicates leadership. In categories with 10+ named competitors, even 15% SOV can be category-leading.
How often should AI share of voice be measured?
Weekly for headline competitive monitoring on top 20 prompts; monthly across the full prompt set for trend analysis. Quarterly measurement misses competitor moves and platform shifts.
