Share of Voice (AI)
The proportion of AI-generated answers in your category that mention your brand, compared to all brands mentioned across the same query set.
Share of Voice (SOV) is a competitive metric borrowed from advertising and adapted for AI search. In traditional marketing, SOV measures how much of the total advertising noise in a category belongs to your brand. In AI search, it measures how much of the total AI citation volume in your category is yours.
Calculating AI Share of Voice
- Define a query set representing your category
- Run queries on target platforms
- For each answer, count all brand mentions (yours + competitors)
- Your SOV = your mentions ÷ total category mentions × 100
Why SOV Matters More Than Raw Citation Rate
A brand with a 40% citation rate looks strong in isolation — until you discover that every competitor has 60–70%. Share of voice contextualizes your citation rate within the competitive landscape.
Conversely, a brand with a 15% citation rate in a fragmented category where the leader has 18% is actually well-positioned.
Improving Share of Voice
- Target queries where competitors are cited but you are not (citation gap analysis)
- Build content that covers comparison and "vs" queries
- Increase brand mentions on sources AI platforms trust (review sites, press, directories)
Frequently Asked Questions
- How is AI share of voice different from traditional SOV?
- Traditional SOV measures ad spend or media impressions. AI SOV measures citation frequency in generated answers — a fundamentally different signal. A brand can dominate traditional SOV but have near-zero AI SOV if its content is not AI-optimized.
- Is higher SOV always better?
- Generally yes, but citation quality matters too. 25% SOV with positive framing is better than 40% SOV where the AI cites you as overpriced or low-rated. Audit the context of your citations, not just the count.
