Very helpful for understanding when DFP considers an ad to have become viewable
by Adam Boritz, 2015-03-04

Really helpful. Good job.
by Giacomo Pallotti, 2015-02-27

Extremely helpful utility. Really highlights the importance of agencies and publishers working together. You can see very clearly how creative load time contributes to a decay in viewability.
