Share of voice
Your share of all the brand mentions, once everyone is counted.
Share of voice is your share of all the brand mentions in these chats.
Visibility asks how often you appear. This asks how much of the conversation is yours when everyone named is counted.
share of voice = your mentions ÷ every brand mention across the chatsWhy it is the harder number
Visibility can be high while share of voice is low, and that combination is common enough to be worth naming: you are in the chat, but so are eleven other people. You have presence without preference.

In the table above the top two are close on both columns: each is named in most chats and each takes a comparable share of the mentions. A brand named in 70% of chats that took 8% of mentions would be a different situation entirely — always present, never the point.
It depends on your competitor list
This is the metric most sensitive to setup. The denominator is every mention of a tracked brand, so:
- A rival you have not added does not dilute your share.
- Adding a large, frequently-named competitor will lower your share of voice without anything changing in the world.
Keep the list stable to keep the trend readable
Like the prompt set for visibility, the competitor set is the baseline here. Add a competitor and expect a step in the line. Add one deliberately, when you have decided they belong in the field you measure yourself against.
Recomma proposes competitors it has actually seen the models naming next to you, which is a better starting list than the one your team would write from memory — the models routinely name rivals you do not think of as rivals.
How to read a change
A rise in share of voice with flat visibility means the same chats are naming fewer other brands, or naming you more prominently among them. That is usually a positioning win rather than a distribution one.
A fall with flat visibility means the field got more crowded. Check the Brands page for a brand that has climbed.
