AI visibility tracking and Share of AI Voice
Citable summary
AI visibility tracking measures how often answer engines cite your brand on the prompts your buyers actually ask. The core metric is Share of AI Voice (SOAV): the percentage of tracked buyer prompts on which an assistant cites your brand versus a defined competitor set. Formula: SOAV = (prompts where your brand is cited) ÷ (total tracked prompts) × 100, measured per engine and rolled up.
The formula
SOAV = (prompts where your brand is cited)
÷ (total tracked prompts)
× 100
per assistant → tracked per answer engine
rolled up → weighted mean across enginesBenchmarks
- 30%+ — Category leader.
- 10–30% — Challenger; steady share to win.
- Under 10% — Structural gap: blocked crawlers, missing JSON-LD, or no answer-ready content.
How to measure SOAV in practice
- Define 20–50 buyer prompts that map to real purchase intent.
- Run each prompt against ChatGPT and Google Gemini on a schedule.
- Parse each response for brand mentions, domain citations, and competitor names.
- Compute SOAV per assistant, then a weighted rollup.
- Track the trend; pair every rising or falling week with the underlying prompt-win-rate delta.
