Cited, not just mentioned
Whether the brand's own pages appear among the sources assistants actually cite for this topic, rather than the brand only being name-dropped via other people's content.
The distinction matters because mentions that ride on third-party content are borrowed ground: the framing, accuracy, and survival of those mentions belong to someone else. Citations of your own pages are the durable form of AI visibility - they put your words in the answer, they compound as assistants keep returning to proven sources, and you control the page they land on.
When this is flagged
A brief flags this when the sources behind the measured answers rarely include the brand's pages - mentions (when they happen) ride on other people's content rather than the brand's own cited pages.
How to fix it
Study which of your pages should be earning citations for this topic and why they are losing to the pages that do. Usually the fix is on-page: state the answer plainly where the winning sources state theirs, back claims with verifiable specifics, and keep the page current. The brief's recommendations identify the highest-value citation gaps to close first.
