Ad Impressions

An ad impression is a metric used to measure the number of times an ad is displayed on a web page. It is typically used in online advertising as a way to track the effectiveness of a campaign. Ad impressions are counted each time an ad is displayed to a user, regardless of whether or not the user interacts with the ad.

Ad impressions can be used to calculate other advertising metrics, such as click-through rate and cost per impression. They are also used to determine the reach and frequency of an ad campaign, and to optimize ad placement and targeting.
