Share of voice
The percentage of AI-generated responses mentioning your brand compared to the total mentions across all competitors for relevant queries.
Share of voice (SOV) in AI search measures your brand's presence in AI-generated responses relative to competitors. It answers the question: "When users ask AI about our category, how often are we mentioned compared to competitors?"
Calculating AI share of voice
AI SOV is typically calculated as:
SOV = (Your brand mentions / Total category mentions) x 100
For example, if you track 100 queries about "project management tools" and your brand is mentioned in 30 responses while competitors collectively appear in 70, your SOV is 30%.
SOV dimensions
AI share of voice can be analyzed across multiple dimensions:
- By platform: Your SOV on ChatGPT vs Perplexity vs Google AI Overviews
- By query type: SOV for informational vs commercial queries
- By topic: SOV for specific features or use cases
- By geography: SOV in different markets or languages
- Over time: Trending SOV to track optimization efforts
Why SOV matters
Share of voice in AI search is one of the most important GEO metrics because:
- It directly measures competitive positioning in AI responses
- It correlates with brand consideration and preference
- It helps quantify the impact of GEO optimization efforts
- It identifies specific areas where competitors are winning
Improving share of voice
To increase your AI SOV:
- Create more comprehensive content than competitors
- Earn more authoritative citations and mentions
- Target queries where your SOV is currently low
- Monitor competitor strategies and respond to their gains
