LinkedIn Ad Revenues $18 Million a Quarter

LinkedIn has 90 million members. They are a little bit older, professional, and wealthy than average, which makes them an interesting demographic for at least some advertisers.

So far, LinkedIn has not been able to convert its audience into ad revenue at a high rate. In the three months ending September 30, 2010, LinkedIn generated just $18 million in advertising revenue.

Advertising might be the key, or most important, revenue source for some sites. But it is harder than you might think to create a big ad revenue stream even for popular social media sites.
