Query: An Empirical Study on Display Ad Impression Viewability Measurements   Display advertising normally charges advertisers for every single ad
impression. Specifically, if an ad in a webpage has been loaded in the browser,
an ad impression is counted. However, due to the position and size of the ad
slot, lots of ads are actually not viewed but still measured as impressions and
charged. These fraud ad impressions indeed undermine the efficacy of display
advertising. A perfect ad impression viewability measurement should match what
the user has really viewed with a short memory. In this paper, we conduct
extensive investigations on display ad impression viewability measurements on
dimensions of ad creative displayed pixel percentage and exposure time to find
which measurement provides the most accurate ad impression counting. The
empirical results show that the most accurate measurement counts one ad
impression if more than 75% of the ad creative pixels have been exposed for at
least 2 continuous seconds.
