The IMRG Online Retail Index tracks the ecommerce performance of more than 200 retailers across the UK. The figures have been published every month since April 2000 and track all online sales, defined as transactions that are completed fully, including payment, via interactive channels. Online sales have built steadily in the UK since the index was launched at the turn of the millennium, but the onset of the coronavirus pandemic in 2020 turbo-charged ecommerce, as an increasing number of consumers purchased goods through digital channels.
