Share of voice in AI — definition & why it matters | BrandGEO Glossary   Share of voice in AI
====================

 The percentage of AI answers in your category that mention your brand versus competitors.

Share of voice (SoV) in AI measures how often your brand appears in AI-generated answers relative to competitors, across a set of category prompts. If buyers ask "best project management tool for agencies" a hundred ways and your brand appears in 12% of the answers while a competitor appears in 40%, that gap is your growth agenda.

Because AI answers are probabilistic and vary by engine, SoV is best tracked as a trend across repeated weekly runs, per engine and per prompt category (discovery, comparison, recommendation), rather than a single snapshot.
