CPV (Cost Per View) in video advertising refers to the pricing model in which advertisers pay for each view of their video ad by a user. This means that every time a user watches the ad for a certain duration, the advertiser is charged for that view. CPV is a popular method for measuring the success of video advertising campaigns, as it allows advertisers to track the number of views and engagement their ads receive. This model is often used in platforms such as YouTube, where advertisers can set a maximum budget and only pay when their ad is viewed. CPV is a cost-effective way for advertisers to reach their target audience and increase brand awareness through engaging video content.
