According to Forrester research on search marketing trends, as presented by Mobile Marketer, 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.
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.
Forrester estimates that mobile's influence on offline retail sales is growing about 6.3% a year and will reach $1.4 trillion by 2021, or about 36% of total retail sales. Mobile will continue to have a growing effect on retail sales in the U.S. in the years to come, says the report.
Mobile paid search ecosystem is catching up to desktop in terms of pricing, says the report, where it has traditionally lagged. In Q3 2017, Google reported that average cost per click grew sequentially for the first time since Q1 2016, indicating that that mobile ads are becoming a positive contributor to search spending.
Forrester points out that Google's average cost per click had declined as its search ad mix shifted to more lower-priced mobile ads. While PC and mobile ad prices had historically risen over time, PC's increase wasn't enough to outweigh the shift to mobile, says the report.
In the mobile market, as smartphone users increasingly search for products directly on the Amazon app, Google faces major competition from Amazon. A comScore survey, says the report, found that 35% of users ages 18 to 34 said the Amazon app was an essential one that they could not go without, compared to only 11% who said the same for the Google search app, pointing to the central role in search and advertising that Amazon has taken among the younger millennial and Gen Z generations.
As mobile's role in search continues to grow, marketers must have a mobile-first SEO strategy in place that address the smaller screens on phones, concludes the report. In 2018, this is likely to become less of an option and more of a must-have, concludes the report.
