Twitter’s net share of U.S. digital advertising revenue reached 1 percent in 2013, a nice uptick from just 0.6 percent last year. eMarketer tips Twitter’s slice of this pie to continue to rise over the next two years, reaching 1.6 percent in 2014 and 2.2 percent twelve months later, more than double its current share.
This, of course, is decent growth, but Twitter’s stake pales in comparison to that of both Google (39.9 percent share now, 42.3 percent by 2015) and notably Facebook (7.4 percent now, 9.0 percent by 2015). Twitter, however, is ahead of LinkedIn (0.5 percent now, 0.8 percent by 2015).
Globally, Twitter has just a 0.50 percent share of digital ad revenues, compared to Facebook’s 5.64 percent and Google’s 31.91 percent.
