LinkedIn adds two members every second; share button on more than 100,000 sites

linkedinLinkedIn recently blew away all expectations in its first quarterly report. Analysts originally predicted a loss for the company that proved them wrong with a revenue of $121 million — an increase of 120% compared to the $54.9 million for the second quarter of 2010.

Clearly, the company has been successful in carving its own niche in the social networking field.

“When we talk to our members, we hear the same thing, they want to keep their professional and personal lives separate,” said LinkedIn’s CFO, Steve Sordello.

LinkedIn’s CEO, Jeff Weiner also revealed at the company’s first earnings call, that the site is adding two new members every second. This is double what it was last November when the company reported it was adding one member per second.

The network is also up from 85 million members to 120 million members — 5 million of those were added in the past month. The company also revealed that over a third of users are active at least once a month.

LinkedIn can also boast they are the second largest social network behind Facebook (and with Twitter not far behind) with 33.9 million unique visitors in June. Traffic through the site has increased overall as it sees 7.1 billion views — an increase of 80% from the second quarter of 2010. Mobile page views alone have increased about 400% year-to-year.

The company also reported that their LinkedIn share buttons are now on over 100,000 sites. Together with innovations like LinkedIn Today, the site’s own social news entity, the company has shown that it is a force in driving traffic. 

Weiner suggested that the company will continue its focus on mobile and will add mobile-specific services in the coming year. LinkedIn will also work to update the features of homepage and company profiles.
