Online sales made with smartphones increased by 101% year-on-year in March, according to the IMRG Capgemini e-Retail Sales Index.
Purchases made on tablets were up just 6% compared to the same month in 2015. In the first three months of the year smartphone usage grew almost nine times that of tablets at 96%, compared to just 11% for tablets.
Total online sales in March were up 11% on February with the average basket size averaging £82.
Richard Tremellen, retail insight and data specialist at Capgemini, said there was “a sizeable shift in consumers’ confidence in online shopping”.
Tina Spooner, chief information officer at IMRG added: “Sales via smartphones continue to surge ahead. There is no doubt that larger screen sizes have enhanced the user experience on smartphones over recent years which is a key factor in the shift towards shopping on these devices. Not surprisingly, many retailers are placing a significant focus on their mobile strategy as consumers shift towards handheld devices when purchasing online.”
