Brand Health Score is a summary of your brand’s performance, shown out of 100. It combines four components: Competitive Ranking, Mention Rate, Sentiment, and Citation Score. Use the components to understand the result. Visibility Momentum is a separate diagnostic. It compares current Answer Visibility with an earlier comparable baseline. It is not one of the four components and does not change Brand Health Score. See Answer Visibility and Visibility Momentum.

​
Metric availability

Each component is either Available or No data.
  • Available means that eligible evidence produced a measured result. A measured result can be zero.
  • No data means that a completed calculation did not have the evidence that the component needs. No data has no number and no green, amber, or red status.
No data is different from an update or an error. An update is not complete. An error means that the calculation failed. Brand Health Score uses the components that are available. The dashboard shows how many of the four components are available. If no component is available, Brand Health Score also shows No data.

​
How to read it

  • A higher available score means that your brand performs more strongly across the available components.
  • A measured zero is a valid result. It is not the same as No data.
  • Open the four components to find the evidence for the score.
  • If a component shows No data, read its reason before you take action.

​
Coverage

Some prompts in a scan do not complete. A prompt can fail for many reasons, including a temporary problem with an AI engine. Mentioned checks how much of a scan completed before it shows a Brand Health Score.
  • At 80% task completion or higher, Mentioned shows the score with no warning.
  • Below 80%, down to 50%, Mentioned shows the score with a warning. The warning states that the result is based on a partial sample.
  • Below 50%, Mentioned does not show a score. It shows an explicit message instead. It does not show a score of 0.
A failed prompt counts against coverage. It does not drop out of the calculation unnoticed. This stops a run of failed prompts from making your score look better than it is.

​
Comparisons

Mentioned compares Brand Health Scores only when both results use the same available components. If the set of available components changes, the current score stays visible but the comparison shows No data. The current dashboard does not yet have a comparable prior Brand Health Score to compare against. It shows No data for this comparison. It does not use Answer Visibility as a substitute. This rule prevents a change in measurement availability from appearing as a change in brand performance. If Mentioned changes how a component is calculated, that is a scoring methodology change. Scores from before and after the change are not compared to each other, and the Answer Visibility chart marks the point where the change happened. Mentioned announces a scoring methodology change before it takes effect. Mentioned also does not compare two results when their coverage is very different, for example a fully completed scan against a partial one. A change in how much of a scan completed is not a change in brand performance.

​
How the evidence is produced

An AI model reads each measured answer and records the mentions, sentiment, rank, and other brands. All four components start from that analysis. See How Mentioned Analyses AI Answers for the method, and for how Mentioned checks it against independent human labels.

Why it matters for AEO

AEO includes more than one brand mention. Brand Health Score helps you review your competitive position, presence, tone, direction, and citations together.
The current Brand Health Score uses the Measured Sample from your latest completed scan. A date filter changes the Answer Visibility history, but it does not change this current snapshot. The score reflects the prompts, AI engines, and competitors in that sample. It does not measure the whole internet. It is also not a measure of sales or website quality.
