Citation rate

The percentage of AI answers that actually mention your brand across a tracked set of prompts.

Definition

Citation rate refers to the share of answers generated by AI engines, across a tracked set of prompts, in which a given brand is explicitly mentioned, cited or clearly identifiable.

Key takeaways

  • It is one of the core GEO KPIs, best read prompt by prompt and engine by engine.
  • A low citation rate on category prompts is often more concerning than a low citation rate on brand prompts.
  • Citation rate must be compared with that of key competitors to be interpreted correctly.
  • It should be read over time: a gradual decline can signal a loss of visibility before it becomes visible elsewhere.

Explanation

Citation rate is calculated by regularly querying a set of prompts representative of a brand’s market, then observing on how many answers the brand actually appears, cited by name or clearly recognizable.

This figure alone is not enough: it must be put in perspective with the framing of the citation (positive, neutral, negative), the relative position against competitors cited on the same prompts, and its evolution over time.

A citation rate that is stable over time but lagging behind direct competitors often points to a presence problem on proof content or third-party sources, rather than a technical issue.
