Scoring Methodology
What Reverb measures and how the public report should be interpreted.
1
Reverb uses one search-grounded API surface for the MVP: Perplexity Sonar.
2
Each approved prompt is sampled multiple times, with the default run using K=5 samples per prompt.
3
Visibility is the rate of answer samples that mention the target brand, always shown with sample size.
4
Share of voice compares target and named competitor mention rates across the same samples.
5
Prominence separates primary recommendation, listed vendor, passing mention, and absent.
6
Citation domains come from search-grounded citation metadata and are aggregated into the source-gap map.
