vCPM
vCPM is the acronym for Cost per Viewable Thousand Impressions.

Cost per Viewable Thousand Impressions
Represents the cost an advertiser pays for every 1,000 viewable ad impressions. Viewable impressions are those ad views that meet industry standards for viewability, ensuring that the ad is displayed in a way that is likely to be seen by the user.
In vCPM pricing, advertisers are charged based on the number of viewable impressions rather than all impressions, whether seen or not. This model is often used for branding and awareness campaigns where the primary goal is to maximize an ad’s visibility to a relevant audience. Advertisers typically set a target vCPM bid, and they are charged based on that bid whenever their ad achieves viewable impressions.
