( CNN ) -- Google 's infant social network experienced a recent growth spurt . Google+ has more than 90 million registered users , Google CEO Larry Page said during the company 's earnings presentation on Thursday . That more than doubles the 40 million that Google reported in October . `` We 're very excited about the growth we 've had , and we 've certainly seen a tremendous number of people added every day , '' Page said . `` That notion of identity is a deep part of what we 're doing . '' Google launched its social network last June . Since then , it has added toolbars and other buttons on its websites to aggressively promote the service . Google stirred up controversy last week when it began giving prominent placement to Google+ pages in results delivered by its search engine . On average , Google engineers have introduced a new feature related to Google+ every day since its launch , Page said . It took Facebook about four years to reach 90 million users , according to Facebook 's public statements . After starting as a students-only service , Facebook now has 800 million people checking their accounts at least once a month , about 10 times that of Google+ . Analysts say Google+ was built specifically to challenge Facebook 's growing dominance on the Web . Google and Facebook generally do not collaborate . Another rival social network , Twitter , complained that the recent changes to Google search favor Google+ and harm Twitter 's ranking on results pages . `` We provide a lot of third-party data in search , and we would love to have more , '' Page said in response to an analyst 's question . `` Generally , companies have been walling that data off . '' People who register for Google+ tend to be dedicated users of Google 's search engine , e-mail and documents services . More than 60 % of them use Google products every day , and 80 % visit a Google site at least once a week , Page said . Page , who posted his comments on his Google+ page , did not say how often or what percentage of users specifically visit its social networking service . `` Engagement on Plus is also growing tremendously , '' Page said . A Google spokesman declined to comment .
