# Metrics overview

> Every number Koalr reports, in one table, with its unit and what to do with it.

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

| Metric                                                    | Unit  | One-line definition                                                             | Read it as                                                   |

| [Prompt Visibility Rate](/metrics/prompt-visibility-rate) | %     | The share of AI answers across your tracked prompts that mention your brand     | The headline. How often you show up at all                   |

| [Site GEO Score](/metrics/geo-and-axo-scores)             | index | How well your pages are written for AI to extract and cite                      | Fix the site, not the answers                                |
| [AXO score](/metrics/geo-and-axo-scores)                  | index | Whether AI crawlers can reach and understand your site                          | Foundational; fix first                                      |

## 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](/set-up/branded-prompts).
