Search giant Google's social networking site has attracted over 90 million users since its launch in June 2011.
"I'm pleased to announce that there are over 90 million Google+ users - well over double what I announced just a quarter ago on our earnings call," Larry Page, Google's chief executive, announced during the company's quarterly earnings call.
"Engagement on Google+ is also growing tremendously. I have some amazing data to share there for the first time: Google+ users are very engaged with our products - over 60% of them engage daily, and over 80% weekly," he added.
The company, however, did not reveal what percentage of the 90 million accounts were active, The Telegraph reports.
For the last six years Google has been consistently struggling to compete against social networking giant Facebook and create a successful social product that can compete effectively for people's time and personal data on the Internet.
Since its launch, over one million Google+ Pages have been created and in excess of 3.4 billion photographs shared on the site.
Facebook, however, has over six billion photos posted to its network every month and approximately 100 billion photos stored on its servers, making it the largest image-sharing platform in the world.
