Comscore MMX Ranks Top-Growing Properties and Site Categories for March 2010

Purchase Incentives Drive Traffic to Auto Manufacturer Sites

Healthcare Reform Boosts Interest at Political News Sites

RESTON, VA, April 19, 2010 – Comscore, Inc. (NASDAQ: SCOR), a leader in measuring the digital world, today released its monthly analysis of U.S. Web activity at the top-growing properties and site categories for March 2010 based on data from the Comscore MMX service. Automaker discounts and incentives compelled millions of Americans to visit auto manufacturer sites to seek information and investigate possible purchases. Political news and information sites also saw sizeable gains in traffic as Americans tuned into the debate over passage of the congressional healthcare bill.

“Auto manufacturers relied on incentives and promotions to boost sales before the end of the quarter, sending more Americans to research their purchases online prior to buying,” said Jack Flanagan, executive vice president of Comscore MMX. “As automakers compete in this challenging market, it is ever more important for consumers to research all of their options online before making these important purchase decisions. Americans also looked to stay abreast of the monumental healthcare bill negotiations in March by closely following political news and information online.”

Automakers Drive the Deals Home

Auto Manufacturers ranked as the top-gaining site category in March, growing 23 percent to more than 30 million visitors, as potential buyers researched vehicle options online.
