Comscore Releases Top U.K. Web Rankings for February 2008

Valentine’s Day Drives Traffic to Flowers, Gifts & Greetings Sites

New Firefox Browser Helps Mozilla Organisation Grow to More than 3 Million Visitors

LONDON, U.K., March 25, 2008 – Comscore, Inc. (NASDAQ: SCOR), a leader in measuring the digital world, today released its February rankings of the largest and fastest-growing Internet properties and site categories in the U.K. based on data from the Comscore World Metrix audience measurement service.

Online visitation figures traditionally dip slightly in February, since the shortness of the month means that there are fewer days on which visits can be recorded. Nonetheless, Valentine’s Day helped drive a strong increase in traffic to the Flowers/Gifts/and Greetings category, which grew 28 percent from January to nearly 7 million visitors in February. Auto manufacturer, career resources and e-cards categories also experienced gains.

Uptake of its new Firefox Internet browser drove visitors to the Mozilla Organisation, which experienced a 48-percent increase to 3.1 million visitors. Fish4Sites grew 24 percent to 3.3 million visitors, driven largely by a jump in visitors to careers resource property, Fish4jobs.
