Overall, US spending on advertising served to desktops and laptops will decline 2.4% in 2014 to $32.39 billion, down from $33.18 billion in 2013.
Google will have a notable influence on the overall shift from desktop to mobile search spending. In 2013, 76.4% of the company’s search ad revenues came from desktop. However, that share will fall to 66.3% in 2014 due to a $770 million decrease in desktop search ad revenues year over year, eMarketer estimates. At the same time, the company’s mobile search revenues will increase $1.76 billion, totaling approximately one-third of Google’s total search revenues.
