## Definition & overview

AI citation rate is a defined measurement of how often a target source is linked in a sampled set of AI answers. Its meaning depends on the denominator, prompt set, engines and collection method; there is no universal formula.

## Analogy & mental model

It is the proportion of sampled reports that include your source in their footnotes.

Choose a documented denominator, deduplicate runs and separate links from brand mentions.

## Why it matters

A percentage is only informative when its denominator is clear. Citation rate can show patterns within a defined test sample, but different prompts or engines may give very different results. It should support diagnosis rather than suggest a universal score for a brand.

## Practical business example

A visibility report separates answers containing a link to the target domain from answers that merely mention the company, and states exactly which buyer questions were tested.

Illustrative scenario, not a client case study or promised result.

## How it works

1. Define the sampled answers, target domain and what counts as a citation.

2. Count qualifying linked references and the agreed total of sampled responses.

3. Report the fraction with dates, engine settings, repetitions and exclusions.

## Core components

- Defined denominator

- Linked-source rule

- Sampling documentation

A small or selectively chosen prompt set can produce an impressive but unrepresentative percentage.

## AI citation rate vs Share of Model

Citation rate specifically concerns linked references under a declared counting rule. Share of Model can include brand presence relative to other brands and needs its own definition.

## Frequently asked questions

What does AI citation rate mean?
AI citation rate is a defined measurement of how often a target source is linked in a sampled set of AI answers. Its meaning depends on the denominator, prompt set, engines and collection method; there is no universal formula.

How is it different from Share of Model?
Citation rate specifically concerns linked references under a declared counting rule. Share of Model can include brand presence relative to other brands and needs its own definition.

What is a sensible first step for a small business?
Choose a documented denominator, deduplicate runs and separate links from brand mentions. Define the sampled answers, target domain and what counts as a citation.

What limitations should I keep in mind?
A small or selectively chosen prompt set can produce an impressive but unrepresentative percentage.
