According to official Google statements, more than 50 percent of search queries globally now come from mobile devices. But we don’t know whether the number is 51 percent or 60 percent, or if it varies significantly by country.
A recent report from Hitwise argues that in the US mobile search is roughly 58 percent of overall search query volume. That’s based on an average of 11 key categories and associated queries analyzed by Hitwise in its “Mobile Search: Topics and Themes” report. The company “examined hundreds of millions of online search queries” across PCs, smartphones and tablets between April 10 and May 7, 2016.
