Share of Voice
Your share of all AI Mentions across the brands you track.
Share of Voice is your share of every AI mention across the brands you track: you plus your competitor set. It is the classic industry metric, applied to AI answers rather than media impressions or search results.
How it is calculated
Share of Voice = your AI Mentions divided by the total mentions of you and every competitor you track, as a percentage.
You and each competitor are measured the same way, on the same answers. The answers are your current board: the latest answer for each tracked prompt on each AI platform, the same answers your AI Mentions and Brand Coverage are counted on, so a Daily Check that refreshes part of the board moves every brand's count together. An answer counts once for a brand when it cites the brand's site or names the brand, however many of its pages it cites. So a Share of Voice of 30% means that, across the answers to your tracked prompts, 30% of all brand mentions in your competitive set went to you.
The change shown next to your share compares against your previous Full Check; when there is no earlier Full Check to compare with, the change carries a "Trend only" label.
Where you see it
- Overview: one of the four headline tiles, with the top competitor's share beside yours, and a Share of Voice card in the competitive context section.
- Competitors: the Ranking tab shows your share and each competitor's share, and the market position chart sizes each brand by its share.
Share of Voice is part of the competitive analysis, so it needs a plan that includes the Competitors page (every plan that runs checks). On Free the tile shows a lock.
When it is not shown as a lead
When no competitor mentions were captured, or the total number of mentions across the set is small, the card says there is not enough data to read the share as a lead. If you track no competitors yet, the tile asks you to add some.
How it differs from Brand Coverage
Brand Coverage is the share of AI answers that mention you. It measures you alone and does not depend on who else you track. Share of Voice compares your mentions with your competitors' mentions, so it depends on the competitor set.
You can have high Brand Coverage and low Share of Voice (you appear in most answers, but competitors appear in them more often), or the reverse.
Because Share of Voice is a ratio, your AI Mentions can rise while your share stays flat: if every brand gains mentions at the same rate, your share does not change.
Competitor set matters
Share of Voice depends entirely on the competitors you track. Adding a competitor that AI mentions often lowers your share; removing one raises it. Keep the list to brands you actually compete with. See Competitors for how the set is built and managed.
