# What is Mention Rate?
> Mention Rate is the percentage of AI responses that recommend a brand when asked about its category — the brand's AI share of voice.
Mention Rate is the percentage of AI responses that mention a brand, regardless of position. A 72% Mention Rate means the brand was mentioned in 72 out of every 100 relevant AI responses.
## Overview
In DecaGEO, a **mention** is counted only when AI recommends the brand as a solution to a category question. Simple name-drops, negative references, and comparison filler are excluded — so Mention Rate measures how often you're genuinely recommended, not how often your name appears.
## How Mention Rate is calculated
```text theme={null}
Mention Rate (%) = 100 × responses that recommend the brand
÷ all responses collected for the category
```
The count runs over all responses collected for the category in the same weekly window.
## Why Mention Rate matters
### It's your AI share of voice
When buyers ask AI about your category, this is the share of answers you're part of — benchmarked against every competitor on the chart.
### It separates frequency from position
Where the [DECA Score](/docs/metrics/deca-score) weights each recommendation by its position, Mention Rate ignores position entirely. Read together, they tell you whether a weak score comes from being absent or from ranking low when present — so you work on the right problem.
### Inclusion comes first
You can't rank high in answers you're not part of. Mention Rate shows whether AI includes you at all — the first thing to build when starting from low visibility.
