Definition
Share of AI Voice is a metric that measures the proportion of AI-generated responses in which your brand is mentioned compared to competitors for a given set of category-relevant prompts. If ten prompts about "best CRM software" are run across AI platforms and your brand appears in six of them while your top competitor appears in nine, your share of AI voice is lower.
Why share of AI voice matters
Traditional "share of voice" in marketing measured media presence across advertising, press, and social media. Share of AI Voice extends this concept to the AI layer — where an increasing number of buying decisions begin.
A higher share of AI voice correlates directly with:
- Brand discovery — More mentions means more potential customers encounter your brand
- Perceived market leadership — Brands mentioned first or most frequently are perceived as category leaders
- Competitive intelligence — Tracking share over time reveals whether your AEO efforts are working or if competitors are gaining ground
How to measure share of AI voice
Calculating share of AI voice involves:
- Define your category prompts — Identify 20-50 prompts your target audience asks AI platforms (e.g., "best email marketing tools," "affordable project management software")
- Run prompts across platforms — Execute them on ChatGPT, Claude, Perplexity, Grok, and Gemini
- Count brand mentions — Tally how often your brand and each competitor appear
- Calculate the ratio — Your mentions divided by total competitive mentions equals your share
The formula: Share of AI Voice = (Your brand mentions / Total category mentions) x 100
Benchmarks
While benchmarks vary by industry, early data suggests:
- Category leaders typically hold 25-40% share of AI voice
- Emerging brands often start below 5%
- A 10% improvement in share of AI voice can take 3-6 months of focused AEO work
