Definition of ad impressions in advertising

 Ad impressions refer to the number of times an advertisement is displayed on a webpage, app, or other digital platform. Each time an ad is shown to a user, it counts as one impression, regardless of whether the user interacts with the ad.


Ad impressions are a fundamental metric in digital advertising, used to measure the reach and visibility of an ad campaign. They provide insight into how often an ad is being viewed and help advertisers assess the potential exposure of their ads.
