# GEO Metrics

> Every GEO number PokPok shows, with the IAB definition, PokPok's formula, its range and where it is available: visibility (mention rate), citation rate, share of voice, momentum and position.

Each metric below carries the IAB's definition (Measuring Visibility in the AI Era, August 2026), PokPok's exact formula, and where it is live. **Read each number with its definition**: two tools can report different figures for the same brand because they count differently.

01 // Presence

## Does the brand appear?

| Metric | IAB definition | PokPok formula | Live |
| - | - | - | - |
| **Visibility** (Mention Rate) | "responses containing a brand mention divided by total responses" | answers naming the brand ÷ all answers, per engine and overall | AI Visibility Truth, report |
| **Citation rate** | "responses containing a brand citation divided by total responses"; a citation is "a linked reference (containing a hyperlink) or a named reference" | answers citing a page of the brand's website ÷ all answers. Named references without a link are not yet counted | AI Visibility Truth: shown today as the brand's share of all citations; the IAB form is not yet available |
| **Share of voice** | "brand mentions as a proportion of all brand mentions within a defined competitive category" | the brand's named answers ÷ named answers of the brand and its tracked competitors. The category is the competitor list the client sets | AI Visibility Truth |
| **Visibility momentum** | "percentage change in Mention Rate or Share of Voice between defined measurement periods" | this period against the equal period before it | AI Visibility Truth |

> [!NOTE]
>
> The IAB: "A brand can have a high Mention Rate and a low Citation Rate; the gap between the two is itself a meaningful signal." Toyota on ChatGPT, 10 days: named in 98.7% of answers, a page of toyota.com cited in 2.7%.

02 // Prominence

## Where, and how prominently?

| Metric | IAB definition | PokPok formula | Live |
| - | - | - | - |
| **Position** | "where the brand appears in the formatted AI response as a user sees it … its rank when multiple brands are listed" | the brand's place among all brands the answer names, in reading order, counted on the whole answer; averaged over answers naming the brand. Win rate = answers where the brand comes first ÷ all answers | Not yet available |

03 // Portrayal

## In what context, with what accuracy?

| Metric | IAB definition | PokPok | Live |
| - | - | - | - |
| **Factual accuracy** | claims about the brand checked against a brand-supplied source of truth | the brand's own page is the source of truth PokPok already holds | Not yet available |
| **Every answer, word for word** | — | the report shows each answer as the engine gave it, the brands it names and how it describes yours | Report |

04 // Reading the numbers

## Three rules the IAB sets, and PokPok follows

PER ENGINE

### Never one combined score

"Providers must report results per platform separately." Every PokPok figure is shown per engine; the overall figure sits beside them, never instead of them.

TRENDS

### A line, not a point

"Single-response measurement is not measurement." The report is one day's answers, labelled as such. AI Visibility Truth asks every day and shows the line.

DISCLOSED

### Every rule on the page

How questions are chosen, how answers are collected, how a mention is counted: all on the [AI Visibility Truth methodology page](https://docs.pokpok.ai/analyse/ai-visibility-tracker-methodology.md), item by item against the IAB's disclosure list.

SCOPE

### What is not measured

Pages the engine read are available for ChatGPT only. Engine model versions are not reported by the apps. No panel, no platform-supplied data.
