"Is $0.21 per VDP view, or per link click? Those aren't the same thing."
A link click on Facebook or Instagram is not a loaded VDP. On mobile, a meaningful share of people bounce, close the browser before the page loads, or tap by accident.
Correct. It's per link click. Meta counts a link click the moment the tap leaves the app, and some of those never finish loading the page. Anywhere on this site that says "VDP click" means a link click to a VDP URL, and the $0.21 is per link click. We don't call them VDP views.
The number that settles this is landed sessions in the dealer's own Google Analytics, matched to the Meta campaign. GA4 landed-session data for August is being pulled now. This paragraph will show link clicks next to landed VDP sessions and the real cost per landed session.
For scale: dealers on DealerRefresh report paying listing sites $0.54 to $1.38 per VDP view. Even if half of these clicks never landed, the cost per landed VDP would be about $0.28.
