validated Media Essentials ™ (vME™) Helps Media Sellers Increase Advertising Inventory Sell-Through and Revenue By Providing Granular Viewability and Engagement Measurement

Madrid, Spain, June 11, 2014 - Comscore, Inc. (NASDAQ: SCOR), a leader in measuring the digital world, today announced that Wolters Kluwer, a leading global information services and solutions company, has selected Comscore for inventory performance evaluation in Spain. Wolters Kluwer will leverage Comscore validated Media Essentials (vME) to measure viewability and ad engagement within its website, helping to identify and package in Spain its high-quality inventory. vME is a comprehensive measurement solution that evaluates ad inventory across a site or network of sites for strategic pricing and packaging and enables media sellers to:

• Understand which ad slots on their websites are performing the best in terms of viewability and engagement (i.e. non-transient mouse-over of the ad).
• Evaluate inventory performance according to different reporting hierarchies, such as by individual ad slots, aggregations of ad slots, entire site sections, and other customizations.
• Re-evaluate their site design, sales strategy and overall approach to advertising packaging and pricing in order to optimize yield and increase revenue.
• Create custom packages and sponsorships for clients that differentiate their offerings from competitors.

"We are entering into the Spanish online advertising market with a strong message to advertisers and planners. Through the use of vME, we will be able to more confidently demonstrate the viewable nature of ad impressions to our clients, highlighting the value of our inventory" said Pablo Villanueva, Wolters Kluwer Strategy Director. “The results are another means for advertising professionals to understand the true value of a media property and the way in which audiences engage with it. Viewability is the next key word to be incorporated to the daily advertising lexicon."
