When AI recommends 5 brands in a category, only one of them is number one. Share of voice in AI search tells you where you rank — and who's taking your position.
Measure Your AI Share of VoiceAI Share of Voice (AI SOV) measures what percentage of AI-generated brand mentions in a given category belong to your brand, compared to competitors. If AI platforms mention your brand in 18 out of 100 relevant queries, and your top competitor appears in 34, your AI SOV is 18% vs. their 34%.
In traditional media, share of voice measured ad spend and impression share. In AI search, it measures something more valuable: which brand AI engines recommend when a buyer is actively researching a purchase decision.
Why AI SOV MattersBuild a list of 50-100 queries that buyers in your category ask AI. Include "best [category]", "recommend a [product]", "compare [your brand] vs [competitor]", and specific use-case questions.
Execute each query on ChatGPT, Perplexity, Claude, Gemini, and Google AI Overviews. Record whether your brand is mentioned, at what position, and with what sentiment.
For each query, record all brand mentions — yours and competitors'. This is how you calculate SOV: your mentions / total category mentions in AI answers.
Break it down: your ChatGPT SOV vs. Perplexity SOV vs. Gemini SOV. Differences reveal where to focus optimization — you may dominate one platform and be invisible on another.
SOV changes are the signal. A 5-point SOV drop in one week signals a competitor moved, a PR piece hit, or an algorithm shift. Catch it early and diagnose the cause.
AI share of voice is the percentage of brand mentions in AI-generated answers that belong to your brand versus competitors, across a defined set of relevant queries. It's the AI-era equivalent of traditional media share of voice — measuring competitive visibility in the channel where purchase decisions are increasingly forming.
Run a defined query set (50-100 category-relevant questions) across major AI platforms. Count total brand mentions across all responses. Divide your brand's mentions by the total for all brands in the category. That percentage is your AI SOV. AnswerMap does this automatically weekly.
In most competitive categories, 15-25% AI SOV for a category leader is strong. If you're the market leader in your space and your AI SOV is below 10%, you have a significant optimization opportunity. If a competitor has more than 2x your SOV, that's an urgent strategic gap.
