US eCommerce Metrics by Device, Q1 2015 [CHART]
Smartphones have grown to represent almost 1 in 5 visits to US e-commerce retailers, per the latest quarterly report from Monetate. But those increases are causing them to drag down overall e-commerce metrics, as smartphones continue to have significantly lower conversion and add-to-cart rates than tablets and computers, indicating that they are still being used more for research than for purchases.
