Measurement

What is the difference between an AI mention and an AI citation?

A mention names the brand. A citation visibly attributes part of the answer to a source.

The short answer

Really Good GEO records an AI mention when the visible answer names the brand. It records an AI citation when the interface visibly attributes information to a source URL or domain. A response can contain a mention without a visible citation, a citation without a brand mention, both, or neither.

This is a measurement taxonomy from Really Good GEO. Product interfaces differ, so record the observable result instead of assuming every product exposes sources in the same way.

Keep four result states separate

Visible answerRecordDo not infer
Brand named and brand page citedMention: yes. Citation: yes.That the result will persist in another run.
Brand named with no visible sourceMention: yes. Citation: no visible citation.Which source or retrieval process produced the mention.
Another page cited but brand not namedMention: no. Citation: record the visible source.That the cited page created brand awareness.
No brand and no visible sourceMention: no. Citation: none visible.That no retrieval occurred.

A citation is not the same as retrieval

Retrieval describes information being brought into the system's working context. A visible citation is an interface-level attribution the observer can record. If the product does not show a source, the test does not establish whether retrieval occurred or which material informed the answer.

Measurement rule: write “no visible citation” when that is what you observed. Do not rewrite an unknown retrieval state as “no retrieval.”

Record enough context to repeat the observation

  • Exact question and question type
  • Named AI product
  • Date and run number
  • Whether visible web search occurred
  • Whether the brand was mentioned
  • Every visible cited domain and URL
  • Competitors surfaced
  • Page version or controlled change

The free AI Citation Test Log keeps these fields together.

Report mentions and citations as separate measures

For a repeated question set, summarize mention observations and visible-citation observations separately. Keep brand-free, comparison, and known-brand questions separate as well. Publish the product, dates, run count, question set, exclusions, and limitations with any result.
