Share of Voice
The key metric for your market share in AI-generated responses.
What is Share of Voice?
Share of Voice (SOV) measures your brand as a percentage of all brand mentions naturally detected in AI-generated responses. We count a mention whenever a brand from your catalogue appears in an answer, whether it is named directly in the answer text or one of the domains it goes by is referenced. Each brand counts at most once per answer.
An example: an AI model answers 100 prompts. Across all responses, brands are detected 500 times. If your brand accounts for 75 of those detections, your Share of Voice is 15%.
How is SOV calculated?
SOV = Your brand mentions / Total brand mentions × 100%
Important: All brands count
The denominator includes all brand mentions detected in the filtered AI answers, not just your defined competitors. Date range, model, and prompt filters therefore change the answer set being measured.
Reading the Share of Voice page
The Share of Voice page brings several perspectives into one place: Which topics, models, and time periods make your brand visible?
- KPI summary: shows your current SOV, the leading brand, and movement versus the comparison period.
- Trend: shows whether visibility is rising, falling, or shaped by individual peaks.
- Model comparison: shows whether you perform differently across ChatGPT, Gemini, Perplexity, and Copilot.
- Prompt and heatmap views: help you find topics where you are strong or currently missing.
Absolute vs. relative: the absolute view shows your share of mentions across every tracked brand, while the relative view renormalizes to 100% across only your tagged competitors. If your mentions stay stable but competitors grow strongly, your relative SOV can still decline.
