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 or domains as a percentage of all naturally detected brand and domain mentions in AI-generated responses. It is based on the domains that appear in the answers.
Simple example
An AI model answers 100 prompts. Across all responses, brands or domains are detected 500 times. If your domain appears 75 times, your Share of Voice is 15%.
How is SOV calculated?
SOV = Your brand or domain mentions / Total brand and domain mentions × 100%
Important: All brands count
The denominator includes all brand and domain 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.
Methodology change in pipeline v2
The new pipeline measures natural URL and brand mentions in real LLM answers. It no longer forces fixed top-10 JSON rankings. Trends remain comparable, but absolute mention counts can shift compared with historical v1 data.
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 view
Absolute shows raw mention counts. Relative shows market shares that add up to 100%. Example: if your mentions stay stable but competitors grow strongly, your relative SOV can still decline.
