Help Center Manage Your Account Ad Tag

How can I measure ad viewability?

Viewability provides a more accurate measurement of ad visibility. A viewable impression is different from a served impression or a delivered impression. A served impression is recorded when an ad is requested, returned and displayed anywhere on the page. It might be at the bottom of the page and is not yet visible to the viewer. On the other hand, a viewable impression is recorded when the ad is visible to the viewer. The Interactive Advertising Bureau (IAB) defines an ad impression is considered a viewable impression happens when 50% of the ad’s pixels are visible in the browser window for a continuous 1 second. To increase the viewability metric for your ads, you can use on-demand/in-view ad loading method.

Setup

To enable viewability tracking, append &viewable=1 to the end of the ad request.
Ad Placeholder:
<div id="ViewableAdPlacement"></div>

Ad Request:
<script type="text/javascript" 
  src="//g.adspeed.net/ad.php?do=js&zids=12345&wd=-1&ht=-1&cb=12345&viewable=1">
</script>

Ad Display:
<script type="text/javascript">
  AdSpeed_div('ViewableAdPlacement',12345);
</script>

Viewability Report

To view the number of delivered impressions, viewable impressions and viewability ratio, follow the menu "Reports / Events / Daily" and click on tab "Viewability".
