Smartphones are the most widely used devices in online shopping traffic.

Computers are no longer the most used device in online shopping traffic: they have been overtaken by mobile phones in the first quarter of this year.

Although it is a marginal difference, the data released by Demandware (a company recently acquired by shows that smartphones accounted for 45.1% of web-shopping traffic, edging out computers at 45% between January and March.

This data refers to the US market but serve as a reference for the rest of the world. The difference may be marginal right now, but it shows that these figures will probably continue to grow in the coming months, and it is even expected that by the end of 2017 smartphones will account for 60% of all web-shopping traffic. If we focus on checkout completion figures, however, smartphones are still ranking behind, 11% lower than computers.

This study complements another study conducted by ComScore, which revealed that online sales through mobile devices have tripled between the second quarter of 2013 and the end of 2015.
