Impression

In online advertising and marketing, an impression refers to the number of times an advertisement is displayed or shown to a user. Each time an ad appears on a webpage, social media feed, or any other digital platform where it could potentially be seen by a user, it counts as one impression. Ad impressions are a key metric for advertisers because they track how many people see their ads. However, an impression does not necessarily mean that the ad was clicked or interacted with by the user, it just means someone saw the ad.
