As many British retailers celebrate a successful Christmas of trading, it appears well-optimised websites have really benefited over the festive season.

Figures from Retail Decisions for the Interactive Media Retail Group (IMRG) show Christmas Day sales online were up nearly a third to £132 million.

Boxing Day sales on the web saw shoppers spend nearly £281million.

Chris Russell, director of e-DigitalResearch thinks Christmas 2010 will be even better for online stores.

He pointed out the importance of website optimisation saying people increasingly ‘use the internet to their advantage, identifying and searching out a bargain’.
