Amazon UK, Argos, Play.com and Tesco.com ranked as most popular UK online stores.
Hitwise has published its 12th quarterly edition of the IMRG Hitwise Hot Shops List, which ranks by popularity (by visits) the top 50 UK online retailers (selling goods and services within the IMRG Index Classification).
Amazon.co.uk, Argos, Play.com and Tesco take the top four places, while Amazon.com and Marks & Spencer make up the rest of the top six.
ASOS also performed well at number 13, having climbed the list during each of the past seven quarters, up from 46 in August 2007.
Other stores in the top 50 which may be of interest to the licensing business included Next (number ten), John Lewis (14), HMV (22), GAME (24), Asda (26), Littlewoods (28), Debenhams (30), Topshop (34), Sainbury's (36), Boots (41) and New Look (46).
"Not making headway online increasingly signals that a retailer may be in trouble - as that is where all of the growth is, and e-retail growth is at the expense of the High Street - so it is telling that still only half the Hot Shops List top ten are High Street brands, and just 30 of the 50 listed retailers have physical stores," commented IMRG's CEO, James Roper.
"These tough times will test brands' staying power and we can expect to see many more radical changes in the retail space this year."
