Proof that mobile retail is the next big thing, M&S have announced that their mobile site saw over 1m unique visitors per day in December. Whilst high street retail sales were decimated in the last month of 2010, it looks like those brands with mobile sites were doing very nicely thank you. Sienne Veit, M&S’s head of mobile said: ‘We’re delighted, as this is confirmation that our customers are ready to shop in this way’. Whilst they haven’t released any sales figures the indication is that shoppers are ready to buy through their mobile. Increasingly the mobile site is the one that customers choose to visit at home, using their smartphones in preference to their PCs.
