Comscore Canada Welcomes Starcom MediaVest Group As Preferred Strategic Partner for Digital Campaign Ratings

SMG Canada to Leverage Comscore vCE™ as the Preferred Tool for Digital Campaign Ratings and In-Flight Campaign Evaluation

TORONTO, CANADA, November 12, 2013 – Comscore, Inc. (NASDAQ: SCOR), a leader in measuring the digital world, today announced SMG Canada will leverage the ad and audience delivery modules of validated Campaign Essentials® (vCE™) to validate the performance of their campaigns. Specifically, SMG will use the tool to measure audience delivery, viewability, brand safety, in-geo delivery and non-human traffic in order to maximize the return of its clients’ digital investments. Using vCE’s real-time reporting and in-flight optimization capabilities, SMG will be better able to improve campaign outcomes and enhance future campaign planning for its clients. As part of this strategic relationship, the two companies have also agreed to work together to develop new ways to integrate the information into daily workflow, as well as compare the output to offline media.

“We’ve selected Comscore as a preferred strategic partner because vCE provides more robust measurement and significant flexibility in terms of usage,” said Jeff Thibodeau, SVP, Digital Media at Starcom MediaVest Group. “The Comscore team has also demonstrated sound leadership in the market, providing support, market education and guidance as the industry evolves toward audience-based buying and selling.”

“SMG believes in the utmost quality, transparency and accountability for our clients, and validating ad delivery through Comscore vCE provides a strong step forward for us,” said Bruce Neve, CEO, Starcom MediaVest Group Canada. “With access to TV-comparable effectiveness measures, like the vGRP, vCE brings a renewed confidence in display advertising and gives us greater control over our campaign planning. As a result, we’re more informed on the effectiveness of every dollar invested and better equipped for future campaign planning on behalf of our clients.”

Brent Lowe-Bernie president of Comscore Canada added, “This preferred partnership with a leading Canadian digital agency is an important validation of the considerable effort we’ve given to making vCE the best-in-class product for digital campaign evaluation and optimization. Measuring digital performance is much more than producing digital ratings. The digital ecosystem and complexities of today’s marketplace demand more sophisticated approaches, data, and insights. We are happy to deliver these all-in-one solutions to our clients.”

About validated Campaign Essentials
validated Campaign Essentials (vCE) is an integrated solution for complete campaign delivery validation and in-flight optimization. Unlike existing single-point solutions, vCE provides an unduplicated accounting of impressions delivered across a variety of dimensions, such as ads delivered in-view, in the right geography, in a brand safe environment, and absent of non-human traffic. It also evaluates the degree to which validated impressions reached the campaign target audience. vCE reports on reach and frequency, comprehensive demographics and behavioral segments. This measurement eliminates all impressions that never had a chance to make an impact, providing a more realistic and accurate picture of campaign delivery.
