Basics · also called CPV, cost per view
CPV (cost per view)
CPV (cost per view) is a video ad pricing model where the advertiser pays each time the video counts as viewed, according to the platform's definition of a view.
Cost per view is mostly used for video. Rather than paying for every time the video player loads the ad, the advertiser pays when it counts as a "view". The catch is that each platform defines a view differently. On YouTube, for example, a view for skippable in-stream ads has historically meant watching 30 seconds (or the whole ad if shorter) or interacting with it.
The metric version is CPV = total spend ÷ views. It is often compared with CPM for video and with completion rate: if you pay per completed view, the model is sometimes called CPCV (cost per completed view).
Because definitions vary, CPV numbers from different platforms are not directly comparable. A "view" in a social feed that autoplays silently for two seconds is very different from a full 30-second Pre-roll on a TV screen. Buyers therefore check the view definition, whether sound was on, and whether the view was measured and verified as human.
Think of it like this
CPV is like paying a street performer only if you stopped long enough to watch the trick, not just for walking past.
An example
A cosmetics brand in Japan spends ¥1,500,000 on a skippable video campaign and gets 300,000 paid views. CPV = ¥5 per view.

Pre-roll
Pre-roll is a video ad that plays before the content the viewer chose to watch begins.
Viewability
Viewability measures whether an ad actually had a chance to be seen on screen; the MRC standard is 50% of pixels in view for one second (display) or two seconds (video).
