Named in 5% of used cars answers, typically in position 1.0. Motors follows at 5%, Carwow at 3%.
Every brand AI names, ranked.
Visibility is the share of answers naming the brand; citation share is its slice of all brand-owned pages cited; read→cited is how often its pages convert a read into a citation.

The referees of used cars.
The independent sources AI models cite when answering used cars questions — the places a brand needs to be seen, reviewed and ranked.
Carwow converts reads into citations. Your brand doesn't.
When Claude or ChatGPT opens a brand's own pages while answering, does the page make the cited-sources list? Carwow converts 56% of reads; Your brand just 29%. That gap is a content problem, not a visibility problem.
