Key takeaways
- A mention and a citation are separate observations under AVJ’s methodology. [1]
- The Citation Index design defines mention rate separately from citation share and presence rate. [1]
- As of Oct. 29, 2026, Google cautions against seeking inauthentic mentions across the web. [2]
Definition: Under AVJ’s methodology, a brand mention records a brand or organization named in the text of an AI answer, regardless of whether that name accompanies a link. [1]
Not to be confused with: A citation, which records a linked source URL.
How is the term used here?
AVJ’s methodology establishes the distinction for its research design rather than tracing a historical origin for the word mention. [1]
A brand can be named without a link to its own website, while a page can be cited without its brand appearing in the answer text. [1] The Index methodology therefore keeps citation metrics and mention metrics separate rather than merging them into one score. [1]
What does Google say about web mentions?
As of Oct. 29, 2026, Google says its generative AI features can surface discussion of products and services from sources including blogs, videos, and forums. [2]
Its guidance cautions against inauthentic mentions and says its generative AI features depend on both quality-focused ranking systems and systems that block spam. [2] That guidance concerns Google Search; it does not establish a measured relationship between web mentions and brand naming across all AI systems. [2]
How does AVJ plan to measure mentions?
The Citation Index methodology defines mention rate as valid answers naming a brand at least once divided by all valid answers in the relevant sample. [1]
Its design combines brand-name and alias dictionary matching with LLM-assisted extraction. [1] It specifies human checking of at least 5% of answers, with a minimum of 50 answers, and reporting precision and recall from that check. [1]
| Observation | Methodological treatment |
|---|---|
| A brand is named in answer text. | Record a mention. [1] |
| A linked source URL appears. | Record a citation. [1] |
| Both appear. | Keep the mention and citation measurements separate. [1] |
These are planned procedures in methodology v0, not evidence that extraction has already been evaluated or that Index results exist. [1]
