Total Mentions is the raw count: how many times your brand surfaced across every tracked prompt in the latest analysis. Where Share of Voice is a percentage (the share of answers that mention you), Total Mentions is the underlying volume.
The two read together. A rising Share of Voice on flat mentions can simply mean competitors faded; rising mentions and share is genuine momentum. And volume gives the other metrics their weight. A 90% Top-Ranked % means far more across hundreds of mentions than across a handful.
Treat it as the denominator-with-context: the absolute footprint your brand has in AI answers, which makes every rate-based metric meaningful rather than a small-sample artifact.
