Impressions (also called Ad impressions) is the amount of times that your banner has been displayed to a visitor on the website which one of your banners are placed on, whether it's clicked or not. Each time a banner is displayed an impression is counted.

An impression is an estimate of the number of people a particular advertisement is reaching, and may be counted in different ways depending upon the way the ad is situated on the page, as well as the number of times the web page where the ad appears is shown.
