CPV, or Cost Per View, is a pricing model used in video advertising that refers to the cost an advertiser is willing to pay for each view of their ad. A view is typically defined as a user watching an ad for a specific length of time, such as 30 seconds. The cost is determined by the advertiser and is usually calculated on a per-view basis.

Unlike other pricing models, such as cost-per mille (CPM), which charge for impressions regardless of whether the user sees the ad, CPV only charges for actual views of the ad. This means that advertisers are only paying for ads that are actually seen by users, which can help to improve the return on investment (ROI) of their ad spend.
