e-course: Ad Viewability

Viewability aims to track only ad impressions that are actually seen by a real human rather than served impressions. For example, if an ad is served at the bottom of a web page but a user never scrolls down to see it, the ad is not counted as a viewable impression. Improve your ad viewability score to increase your ad fill rate and CPMs.
