While detailing its earnings for the second quarter of 2012, LinkedIn reported that it currently has more than 175 million users active on its professional network. Earning more than $228 million in revenue between April and June was a good sign for the company, which has been increasingly innovating for users and marketers in recent months.

According to a release from the company, the highlights from the second quarter include the rollout of an iPad app, targeted status updates, the development of Talent Pipeline for recruiters on the network and a homepage redesign (which Brafton reported places an emphasis on relevant – over recent – content).

Many still view the site’s primary use as a job-finding and career advancement tool. However, social media marketing with LinkedIn continues to increase, with more than 2 million companies using the site’s Pages to appeal to new audiences.

Other additions made this year that have positioned LinkedIn as an ideal place for marketers to share content include LinkedIn Answers. The forum and discussion tool helps a company establish itself as an authority among prospects by creating a space to their questions and concerns directly.

Frequent innovation from LinkedIn and strong performance indicators are especially important as B2B social media marketing becomes more popular and useful for businesses. Interest in the LinkedIn has spiked in 2012, and it’s no surprise, as Brafton reported early this year that developing a presence on the platform was among the top priorities for marketers.
