All scores are 0 to 100 and higher is better. Percentages and “out of 100” are the same number written two ways.

Rates and averages behave differently when a brand is absent

A tracked competitor with no mentions in a run scores zero on Prompt Visibility Rate and Share of Voice: absence is a real zero for a rate over all answers. Sentiment and First Mention Rate are averages over mentions, so with nothing to average they stay blank rather than showing a fabricated “terrible” score.

What was retired

Koalr used to show a blended “Overall” or “AI Visibility Score” composite. It was retired in favour of one clear headline, Prompt Visibility Rate. The free check on koalr.ai still uses the older name for its mention-rate result; inside the app there is no composite anywhere.

Branded prompts are excluded

Every rolled-up metric excludes prompts that name your brand. See Branded prompts.
