The latest quarterly IMRG comScore Top 50 Retailer Ranking, based on June data from the comScore MMX Multi-platform, sees Amazon UK retain its top spot from June 2015, with Argos up one place in second, Apple down one place in third, Tesco holding on to fourth place, and Netflix up one in sixth.

The Ranking is published quarterly and measures digital audiences on desktop and mobile, based on comScore MMX Multi-platform data of those selling goods and services within the IMRG Capgemini Index Classification in June 2016, in the UK. The goods and services covered include everything from beer and wine to household goods and theatre tickets. However, eBay, marketplace and price comparison or aggregator websites are not included.

The study also breaks out rankings for smartphone and tablet traffic. Amazon UK once again tops the smartphone charts, with the next four places taken by, respectively, Tesco, Apple, Argos and EE. It’s a similar story in the tablet rankings, with Amazon UK in first, and the next four places occupied by Apple, Tesco, Argos and Netflix.

BA was the biggest climber in the smartphone rankings, rising 48 places on June 2015 to finish in 30th place. On tablets, the biggest climber was First Choice, which climbed a remarkable 159 places to finish in 23rd.

Amazon UK, Argos, Tesco and Apple took the top four places across all rankings – overall, smartphone and tablet – which has been the case for the past three quarters.
