Grounding source, citation, mention · The 3 levels of AI visibility
In an AI answer, being a grounding source, being cited and being mentioned are three different events. The source is read by the model without the user seeing it, the citation is the link shown, and the mention is the brand name written in the answer text.

Why separate grounding source, citation and mention?
Because these three outcomes are produced at different steps. Dejan explains that most confusion in AI visibility measurement comes from blending them. A page can be read without being cited, and a brand can be named without any of its pages being cited.
What decides each level in an AI answer?
The grounding source depends on retrieval: sub-queries, relevance, filtering. The citation is a subset of sources the model chooses to show. The mention is a generation decision, mostly driven by what the model already believes about the topic, its primary bias.
How do you track these three levels in a GEO tool?
Check what the tool actually counts: URL citations, brand mentions or retrieved sources. A publisher mostly wants citations, a brand mostly wants mentions. Good tracking separates the two.
Frequently asked questions about Grounding source, citation and mention
Does a citation always lead to a mention?
No. A citation attributes a claim to a page, it does not guarantee your brand appears in the text the user reads.
Which of the three matters most?
It depends on the goal. For traffic, citations. For awareness and recommendation, mentions.
