IAB: desktop and mobile paid search bring in roughly half of 2015 digital ad revenue

Earlier today the IAB released its Q4 and full year 2015 digital ad revenue report for the US market. Online ad spending last year was worth nearly $60 billion ($59.6 billion), which represented more than 20 percent growth over 2014.

Below is the 2015 breakdown by ad category:

Desktop-based paid search brought in 34 percent of total ad revenue or roughly $20.3 billion. This was down from 38 percent a year ago. However real dollars grew by more than $1 billion over 2014.

Mobile ad revenue was approximately 35 percent of the 2015 total or $20.8 billion, a 66 percent increase from the 2014 total ($12.5 billion). Of the 2015 mobile total, 43 percent ($8.9 billion) was from paid search.

The combined value of paid search on the desktop and in mobile was roughly $29.2 billion in 2015. Accordingly, the total search market represented approximately 49 percent of total digital ad revenue in 2015. By comparison, the combined value of desktop and mobile display (defined broadly to include video and other formats) was $24.6 billion or 41 percent of total digital revenue.
