A new report released by comScore revealed that Facebook.com grabbed the number one ranking among Social Networking sites in India- based on traffic, for the first time in July with 20.9 million visitors.

The report said that more than 33 million Internet users age 15 and older in India visited social networking sites in July, representing 84% of the total Internet audience.

India now ranked as the seventh largest market worldwide for social networking, after the US, China, Germany, Russian Federation, Brazil and the UK.

The total Indian social networking audience grew 43% in the past year, more than tripling the rate of growth of the total Internet audience in India.

ComScore said that Orkut grabbed second position with 19.9 million visitors (up 16% vs. year ago), followed by BharatStudent.com with 4.4 million visitors (up 3%), among Social Networking sites in India.

According to the report, Twitter.com registered the highest rate of growth among the top five social networking sites, increasing 239% to 3.3 million visitors.

Yahoo! owned two of the top ten social networking sites: Yahoo! Pulse (3.5 million visitors) and Yahoo! Buzz (1.8 million visitors).

comScore executive vice president for the Asia-Pacific region Will Hodgman said that the social networking phenomenon continues to gain steam worldwide, and India represents one of the fastest growing markets at the moment.

"Though Facebook has tripled its audience in the past year to pace the growth for the category, several other social networking sites have posted their own sizeable gains," Hodgman said.
