Which term refers to the count of ads served to a user?

The term that refers to the count of ads served to a user is "ad impressions." An ad impression occurs each time an ad is fetched and displayed to a user, regardless of whether the user interacts with it. This metric is crucial in digital advertising as it helps advertisers understand how many times their ads are shown and provides insights into the visibility and reach of their campaigns. Ad impressions are a fundamental measure of advertising performance, giving a clear picture of how often users are exposed to an ad.

While ad clicks, ad engagements, and ad views are relevant metrics in the advertising assessment process, they focus on different aspects of user interaction with ads. Ad clicks measure the number of times users actually click on an ad, reflecting interest or action taken. Ad engagements encompass various user interactions, such as clicks, shares, and likes, indicating a deeper level of user involvement. Ad views, while similar to impressions, can sometimes refer to the actual viewing duration of a video ad. However, the standard and most widely recognized term for the total count of ads served is ad impressions.
