Top Global Properties

Microsoft Sites topped the list as the most visited global property in June 2006 with approximately 500 million global visitors, followed by Yahoo! Sites (481 million visitors), and Google Sites (454 million visitors). Yahoo! Sites led all global properties with 116 billion page views during June, followed by Google (84 billion page views), and Microsoft Sites (75 billion page views).

“The ‘big three’ properties continue to aggregate the largest worldwide audiences, dominating the rankings,” said Bob Ivins, managing director for Comscore Europe. “MSN, Yahoo! and Google ranked as the top three respectively, each drawing more than 450 million visitors in June, approximately 200 million more than the next closest property. While the established Internet players grabbed the top spots in the worldwide rankings, several upstarts have quickly found their way into the top 15 properties. Wikipedia Sites ranked 8th on a worldwide basis in June with 128 million visitors, while MySpace ranked 15th with 66 million visitors worldwide.”
