![Social Network Ad Revenues to Hit $10 Billion in 2013 [STUDY]](https://helios-i.mashable.com/imagery/archives/05DGYxaDzFUiiXCHTT2ZlLi/hero-image.fill.size_1248x702.v1647020300.jpg)
The bulk of those revenues are going toward Facebook with Twitter in second place. LinkedIn, meanwhile, will snag 3% of global social network ad revenues, with $140.8 million. The researcher notes that although LinkedIn's ad revenues have tripled in two years, its growth is slowing. Clark Fredricksen, a rep for eMarketer, says that LinkedIn ought not be too concerned. "LinkedIn's made it pretty clear that the horse they're riding is their recruiting business," says Fredricksen. "But they make a handy chunk from advertising for sure."
The growth of social network advertising, meanwhile, is clearly coming at the expense of other forms of advertising. This year, 8.8% of U.S. ad dollars and 6.9% of global ad spending is going toward social networking sites. By 2013, those figures will jump to 11.7% and 9.4%, respectively, according to eMarketer.
Those numbers are a slight revision of eMarketer's January estimate of $5.9 billion in U.S. revenues in 2011. Fredricksen says the reason for the change is "better information" about Facebook's ad business. That said, Fredricksen says the adjustment is very small and eMarketer still expects growth around 104% for Facebook's ad business this year.
