Facebook Ad Revenues to Surpass $4.2 Billion in 2011

eMarketer predicts that Facebook will garner $4.27 billion in 2011. With a worldwide estimate of $3.8 billion from advertising at year’s end, Facebook will surpass Yahoo’s (NASDAQ:YHOO) total sales from 2010.

Although global ad revenues generate much of the company’s earnings, Facebook Credits may bring in as much as $470 million this year. With plans to diversify its revenue stream, Facebook will downshift its emphasis on advertising from 95% of total revenue in 2009 to 89% this year. As a result, Facebook Credits may comprise up to 11% of the company’s 2011 total revenue.

“Facebook is expected to earn $2.01 billion in US ad revenues in 2011 … The company’s share of the $12.33 billion US display ad market will reach 16.3% in 2011. eMarketer’s estimates for US display ad revenue at Google (NASDAQ:GOOG), Microsoft (NASDAQ:MSFT), AOL (NYSE:AOL) and Yahoo (NASDAQ:YHOO) were not affected by this forecast,” says eMarketer.
