comScore Reports Second Consecutive Month of Sharp Gains in Unique Visitors for Clearspring

Category Leadership Gap Continues to Widen With Growing Popularity of Social Media


MCLEAN, VA--(Marketwire - December 3, 2008) - Clearspring Technologies, the leading widget and sharing network connecting publishers and advertisers to audiences on the social Web, experienced a greater than 30 percent increase in worldwide usage of its sharing service between September and October. This increase comes on the heels of a 59 percent increase from August to September after Clearspring acquired social bookmarking leader AddThis. The company attributes this most recent increase to a number of factors including organic growth and new partnerships.

According to comScore, Clearspring logged more than 332 million unique visitors worldwide in October, easily outdistancing its nearest competitor by over 150 million visitors. In addition, comScore revealed that the company further extended its lead in the U.S. market in October with over 120 million unique visitors, an increase of 19 percent from September.

"The comScore data points to a much larger trend in social media that is continuously gaining steam," said Hooman Radfar, chief executive officer and co-founder of Clearspring. "The value of sharing various types of content across the Web combined with the excitement displayed by Internet users to do so is clearly demonstrated by the frictionless growth of widget media."

As announced in September, Clearspring acquired AddThis, the No. 1 bookmarking and content sharing service on the Internet, helping the company to grow to a size comparable in reach to the fourth largest property on the Web. Clearspring has since delivered on promises to add to and improve the features of AddThis, recently announcing optimization of the sharing button and language support for 17 additional languages, among other improvements. The company anticipates that this will continue to fuel growth of its sharing services.

comScore is a leading source of data and metrics for both the digital world as well as mobile usage that is trusted by brands such as AOL, Microsoft, Yahoo!, Best Buy and more. Statistics quoted in this release are found in comScore's October 2008 Worldwide report.
