Share of Voice (AI)

Share of voice in AI search is your brand's mention rate relative to direct competitors in the same prompt set across AI assistants.

Calculated as: (your mention rate) ÷ (your mention rate + competitor mention rates) × 100. Useful for relative measurement when absolute mention rates fluctuate with prompt-universe changes or model updates.

The metric is most reliable when computed against a defined competitor set (3–5 named brands) over a static prompt universe (100+ prompts) sampled weekly.

For B2B SaaS in 2026, top-decile share of voice runs 35–50% in well-defined niches and 10–25% in fragmented categories.
