Share of voice (AI)

Definition
Share of voice in AI search is the proportion of brand mentions a company captures within AI-generated answers for a defined prompt set, relative to named competitors. If five brands are mentioned across 100 prompts and yours appears 25 times, your share of voice is 25% — the AI analogue of SOV in traditional media monitoring.
Relative visibility, not absolute
AI Visibility Score asks how present you are. Share of voice asks how present you are versus the category. A brand can score 60/100 on visibility yet trail on SOV if every answer names three competitors more often. SOV is the metric for competitive GEO reviews and board slides.
How AI SOV differs from SEO share of voice
SEO SOV often proxies organic click share or rank distribution. AI SOV counts mentions in generated text — including cases with no click and no link to your site. Co-mention matters: being listed second every time is different from being listed first half the time. Good programs track mention rate, average position, and AI sentiment alongside raw SOV.
In Asian markets
Competitor sets differ by country — the brands Singapore buyers compare are not identical to Japan’s. SOV must be computed per market with locally relevant competitor lists; a global SOV number blends unrelated competitive dynamics.
Example
Across 50 “best [category] Singapore” prompts, Brand A is named 40 times, Brand B 30, Brand C 20. Brand A’s SOV is 40%. Brand C invests in localized PR and moves to 35% while A flatlines — visible in SOV before it shows in organic rank tools.
