Google's social service boasts 343 million active users.
Google+ has surpassed Twitter to become the world's second leading social network, with Facebook maintaining its market leader position.
GlobalWebIndex revealed the usage figures with a report showing a change in usage from localized social platforms to global social networks including Facebook, Google+ and Twitter.
Google+ now boasts 343 million active users, while Twitter has slightly under 300 million active users. However, the latter experienced the strongest growth with 40 percent across 31 markets, which accounts for around 90 percent of the world's internet users.
Twenty one percent of worldwide internet users utilize Twitter, while 51 percent use Facebook and Google+ boasts a 25 percent share. YouTube, which is owned by Google itself, is tied with Twitter with 21 percent.
GWI said Mark Zuckerberg's website has not been affected by "Facebook fatigue" and saturation in order to achieve around a 33 percent growth margin. Google+, meanwhile, grew by 27 percent.
Facebook announced during October of 2012 that it has surpassed one billion monthly active members. In December, Google+ reached 500 million registered users and 135 million active members.
Although this was before the announcement of Graph Search, Google co-founder and current CEO Larry Page recently said that Facebook is "doing a really bad job on their products," and stated that Google+ can coexist with Facebook.
Page's comments were preceded by Google+'s VP of product stressing that Facebook is a social network of the past and that it's "pissing users off" due to its intrusive advertisements.
