Search ad revenues continued to rise in 2013. The record-breaking revenues last year totaled $18.4 billion, accounting for 43 percent of all Internet ad revenue, compared to $16.9 billion and 46 percent in 2012, according to the Interactive Advertising Bureau (IAB).
Search accounted for more revenue than display and mobile combined in 2013, and that declines in the overall share is due "to growth in Mobile and Mobile Search, which is included in the Mobile category," according to the latest IAB Internet Advertising Revenue Report, which is conducted on behalf of the IAB by PricewaterhouseCoopers (PwC).
Just in Q4 2013, search revenues totaled $5 billion, 41 percent of all ad revenue, up from Q4 2012 when search revenue totaled $4.6 billion.
Overall, the IAB reported total U.S. digital advertising revenues of $42.8 billion for 2013 – up 17 percent from $36.6 billion in 2013. That figure is also noteworthy because, for the first time, more ad revenue was generated via Internet advertising than broadcast television. Also, after a record-breaking first half of 2013, In Q4 digital ad revenues surpassed $12 billion.
Display advertising accounted for $12.8 billion (30 percent) in 2013, up 7 percent from $12 billion in 2012.
Mobile advertising continues to grow rapidly, as mobile revenues hit $7.1 billion (17 percent) in 2013, a 110 percent increase from $3.4 billion in 2012.
