Comscore MMX Ranks Top 50 U.S. Web Properties for April

Google Sites Capture #1 Property Ranking for the First Time

April 15 Deadline Prompts Surge of Traffic to Tax Sites

RESTON, VA, May 15, 2008 – Comscore, Inc. (NASDAQ: SCOR), a leader in measuring the digital world, today released its monthly analysis of U.S. consumer activity at the top online properties for April 2008 based on data from the Comscore MMX service. April saw Google Sites attain the number one spot in the Top 50 U.S. Properties ranking for the first time in its history with a total audience of more than 141 million visitors. Content categories showing gains in April included job search, career resources, and television sites.

“April was a very active month. Google took the top property position, thanks to continued search growth and rapid growth at YouTube,” commented Jack Flanagan, executive vice president of Comscore MMX. “The significant traffic growth at tax sites, which began in January, reached a crescendo by the tax filing deadline on April 15 as taxpayers sought information, forms, and online filing facilities. The return of the network television programs after the writers strike sent fans to a variety of sites to get information on their favorite shows, catch up on episodes they may have missed, get refreshed on plotlines, and to stream new episodes.”

Top 50 Properties

Google Sites captured the top position in the Top Properties ranking for the first time, reaching 141 million Americans in April. Yahoo! Sites ranked second with 140.6 million visitors, followed by Microsoft Sites with 121.2 million visitors. Superpages.com Network and CareerBuilder LLC both jumped eight spots in the ranking to positions 18 and 30, respectively.

Deadline Drives Traffic to Tax Sites

Americans racing to file their taxes by April 15 propelled gains at several tax-related sites. IRS.gov grew 35 percent to 23.4 million visitors, ranking as one of the top-gaining properties for the month. Intuit rose 11 percent to 13.3 million visitors, while TaxACT drew 5.2 million visitors and H&R Block attracted 4.2 million visitors.

Job Search and Career Sites Experience Gains Fueled by Graduates and the Economy

Job search and career resource sites both experienced gains in April, as impending college graduations and an uncertain economy had Americans taking steps to control their careers. The job search category grew 5 percent increase to 17.2 million visitors, led by gains at Indeed.com Job Search (up 10 percent to 4.7 million visitors), SimplyHired.com Sites (up 29 percent to 3 million visitors), and AOL Find a Job by CareerBuilder.com Job Search (up 22 percent to 1.4 million visitors). The career resources category saw a 3-percent increase during the month to 44 million visitors, led by CareerBuilder LLC with 23.9 million visitors.

Television Sites Gain as New Episodes Air

With the writers strike resolved, many television shows finally returned to the airwaves in April with new episodes, causing the TV category to increase 4 percent to 93.2 million visitors. Yahoo! TV led the category with 15.6 million visitors, a 38-percent increase versus the previous month, followed by AOL Television with 12.5 million visitors and MySpace TV with 12 million visitors.
