By 2013, social network advertising revenues will reach $10 billion worldwide, up from $5.54 billion this year, according to eMarketer. Facebook is set to grab the lion’s share of those revenues, with Facebook’s ad sales expected to climb from $3.8 billion this year to $7 billion in 2013 (70 percent of the total).

Twitter’s ad sales are expected to rise from $139.5 million in 2011 to $399.5 million in 2013. LinkedIn will also see impressive ad revenue gains. eMarketer expects LinkedIn’s ad sales to grow from $140.8 million this year to $249.6 million in 2013.

The growth in social network ad spending will see social networking sites account for a larger share of all online advertising. Currently making up about 6.9 percent of worldwide online advertising (8.8 percent of U.S. online advertising), social networks will assume 9.4 percent of global online advertising in 2013 (11.7 percent in the U.S.).

eMarketer’s estimates are based on a “meta-analysis” of qualitative and quantitative factors, including revenue figures and other firms’ research findings.
