Capgemini and IMRG, which made the findings through a new tracking initiative called the Quarterly Benchmarking Index, found that mobile sales accounted for 3.3% of all online sales during the first quarter of 2011, up from 0.4% for the same quarter last year.
The quarterly Index tracks customer acquisition, basket abandonment rate and order fulfilment across retailers including John Lewis, Marks & Spencer and Debenhams.
The findings showed that the percentage of visits to retailer’s websites via mobile devices had increased to 7% in the first quarter of 2011, up from 1.4%.
It also said that checkout abandonment rates dropped from average of 37% to 32%.
David J Smith, chief marketing and communications officer at IMRG, says: “Mobile has been discussed for a while now as an important channel for retailers to engage through, and with some retailers having up to 12% of their traffic coming through that channel, its popularity among consumers is clear.”
