Mobile phones will drive most of the expansion in paid search ad spending, contributing an estimated 69% of the $19 billion in growth by 2022, according to Forrester research on search marketing trends by Robert Williams, first published on Mobile Marketer.
U.S. mobile search users are forecast to grow to $242.8 million in 2022 from $204.4 million last year, or about 3.5% a year, says the report.
