IAB OK’s Trading on Viewability

For three years, we’ve been screaming that in digital advertising, there’s no such thing as “below the fold,” with its devalued impressions. We asserted that if an ad is seen by a visitor,it should be paid for. Now, IAB‘s new standard has directed that this should and will happen. Above and below the fold will no longer be the determinant. The new determinant will be viewability.

The IAB, after much sturm und drang ( 18 months of committee meetings and discussions at leadership summits)  released its standard for viewable display impressions last week. As expected, a viewable ad is one in which a minimum of 50 percent of pixels are in view for a minimum of 1 second. It doesn’t matter where that ad is placed on the site.

This shouldn’t be news to any of us; we have been following the issue of viewability and wondering when advertisers would start buying for it. Now that the Media Rating Council has lifted its November 2012 Viewable Impression Advisory for Display Advertising, the industry should start making transactions using viewable impression currency immediately.

IAB has a list of vendors certified by the MRC, and although their measurements can vary plus or minus five per cent, agencies with brand advertising campaigns will expect guarantees on viewable impressions. As for ZEDO, we’ve been working with comScore since it was AdXpose, and our high impact formats are all certified 99% viewable.

However, the bad news is all of this applies only to display advertising for now; video won’t be available for trading until June and video is the fastest growing segment of the online advertising business right now.

As IAB’s Sherrill Mane wrote,

Publishers who have been testing display viewability data know all too well that the investment in resources is substantial. You need to finance purchase of data from multiple measurement vendors, assign the right teams of people to develop test parameters, conduct enough comparisons so that you have an idea of how to forecast inventory and optimize yield. Even if all the steps are executed well, you are likely seeing variances across vendors. Some of the variances may be greater than what you’d need for confidence in the decisions you need to make.

Before you go nuts trying to decide which vendor you are going to use to measure viewability, you might want to take a look at IAB’s reconciliation study, which examines the different methodologies used by the vendors.

If you happen to like comScore, all currently used ZEDO high impact formats are certified by comScore.
