Impressions and pay-per-view (PPV) ads are closely related but serve different roles in digital advertising. An impression is counted each time an ad is displayed on a user's screen, regardless of whether it is watched or engaged with. In contrast, a PPV ad is only counted—and paid for—when a user actually views the ad for a minimum duration or interacts with it. While impressions reflect how many times an ad was shown, PPV focuses on meaningful engagement. This makes PPV a more performance-based model, ensuring advertisers pay only for active attention. Impressions are useful for measuring reach, while PPV ads are better for evaluating viewer interest and message retention. Together, they offer a fuller picture of an ad campaign's effectiveness.
