In official Google statements, it’s said that over 50 percent of search queries globally now come from mobile devices. But what’s the exact percentage? We aren’t sure, or if it varies significantly by country.
In a recent report from Hitwise (registration required), it’s argued that in the US mobile search is about 58 percent of overall search query volume. This is based on average of 11 key categories and associated queries analyzed by Hitwise in their “Mobile Search” Topics and Themes” report. Hitwise “examined hundreds of millions of online search queries” across PCs, smartphones and tablets between the dates of April 10 and May 7, 2016.
The following graph is the share of online searches initiated on a mobile device, by industry
When you look at the category that has the highest percentage of mobile search volume, you’ll see it’s “Food & Beverage,” with 72 percent. The lowest category for lowest volume on mobile devices was banking, at 39 percent. Banking got 61 percent on desktop searches.
The report also found that mobile queries are slightly longer than PC search queries. With Food & Beverages, the average PC query string was 13.8 characters, here the mobile queries were 15.5 characters. This is just over a two word difference. There isn’t much else the report provides when it comes to additional insight or detail by category on query length.
