The launch of Google’s new social networking site, Google+, had set off of debate over its potential for survival in a field dominated by Facebook.

Google+ had got off the block quickly with a user base of 20 million unique visitors as of July 19, according to Comscore data.

The U.S has been leading the traffic with 5 million visitors, up 81 percent from the previous week and 723 percent from two weeks earlier, followed by India with a 2.8 million visitors, UK (867,000 visitors), Canada (859,000 visitors) and Germany (706,000 visitors) .

India has played a major role in driving Facebook’s web traffic as well. However, Facebook, which has a user base of 750 million active users, has seen a decline in the users in US and Canada by an approximate 6 million. Most of Facebook’s traffic is driven by the countries which adopted the networking site later on — Mexico, Brazil, India, Turkey, while it has seen saturation in the US and Canada. The US constituted more than 50 percent of the web traffic of Facebook in 2009 and 2010, when the site had seen rapid growth altogether.

The current growth of the Google+ reflects the interest of the early adopters and to continue with the current frenzy, it will also need to attract regular participation among users to cultivate such an effect.

Google+ has beaten other networking sites in terms of gathering a large user base in the initial period. This was easier to attain for Google as it already has a built-in visitor base of more than 1 billion to work with, though it still exists at an invite only level and Google has not started marketing the service on other properties yet.
