DEFINITION
AI share of voice
A brand’s share of observed mentions or citations within a defined set of AI-answer samples.
Reviewed August 28, 2026
The metric only has meaning when the query set, comparison group, platforms, time window, and treatment of multiple mentions are defined. Different definitions can produce different percentages from the same category.
A transparent calculation
One simple form divides a brand’s observed appearances by all competitor appearances in the same sample. Other forms calculate the share of prompts containing the brand. State which form is used and retain the underlying observations.
How to interpret change
A rising share can reflect stronger visibility, weaker competitors, a changed prompt set, or platform variation. Compare like-for-like samples and avoid treating short movements as proof of causation.
