Google has said its AdSense policy will now allow 300 x 250 ads “above the fold” or visible on a mobile webpage before scrolling. And it noted that its own research indicated that a 300×250 ad unit placed just below the fold could generate an approximate 50 percent viewability rate. The change seems to be prompted by the release of ever-larger smartphones, allowing for space on the screen around the ad to carry content. There are, however concerns that the ads will detract from user experience. The restriction on this size was originally put in place precisely because of the non-user-friendly aspect of this type of ad. In addition, Google’s new rules also apply only to mobile-first ads, which means they won’t affect any other types of ads.
