Defined by the IAB (Internet Advertising Bureau) and the MRC (Media Rating Council) viewabiltiy is a measure of whether an ad is, or reasonably can assumed to be, seen by a visitor. The baseline for viewability is 50% of the ad is on the screen for 1 second. PubWise employs various techniques like Lazy Loading, Viewable Refresh and more to ensure the value of inventory is retained by improving viewability.
