what is the difference between share of voice and rank-1 share?

Updated June 30, 2026 · Reviewed by Mack Grenfell · Asked 33 times

Share of voice is how often a brand appears relative to all mentions in the run. Rank-1 share is how often that brand is the very first one AI names. Both sit on the competitors leaderboard, and they answer different questions: who gets mentioned the most, versus who AI reaches for first.

The leaderboard columns

| Column | What it tells you | |--------|-------------------| | Visibility | Share of your tracked prompts where the brand shows up at all | | Change | How that share moved over the selected window (7/14/30/90 days) | | Status | Threat, rising, trailing, or stable, from movement against the field | | Wins / losses | Head-to-head record against you, prompt by prompt | | Share of voice | How often this brand appears, across all mentions | | Rank-1 share | How often this brand is named first |

How to read them together

A competitor can have high share of voice but low rank-1 share, meaning they get mentioned a lot but rarely lead the answer. Click any row to expand the head-to-head: their trend against yours, the exact prompts each of you wins, the gap on each one, and the citation sources behind their wins.
