# What is an AI citation?

> An AI citation is the event of a generative engine (ChatGPT, Claude, Perplexity, Gemini) referencing a web page inside an answer. Citations take four practical forms — inline link, footnote, named-without-link, and paraphrased-without-attribution — each with different measurability and brand-attribution properties.

## Four citation forms

- **Inline link.** Highest measurability; click events trace back.
- **Footnote / superscript.** High; numbered references resolve to source list.
- **Named without link.** Medium; brand mention measurable, no click attribution.
- **Paraphrased without attribution.** Low; detectable only by manual content matching.

## Measurement principle

Track citation rate per query, not absolute citation count. The denominator matters: getting cited on 8 of 10 high-intent queries is worth more than 80 citations on long-tail queries no one asks.
