The retailer said that Empire Direct.co.uk now has larger text, contrasting colours, alternative text tabs and a simple navigational toolbar to give it a wider audience appeal.
"The consumer electronics industry has emerged as the market most conscious of current lifestyles. Our revised site is designed to reflect this and make the online-shopping experience as rich and enjoyable as possible for customers," said Paul Sweeting, head of EmpireDirect's web development team.
Users can search the site by keyword, phrase or product, but EmpireDirect claims its system will be able to serve relevant results if words are mis-spelt.
The site has added a bulletin board and is trialling rotational 3D images to give customers a holistic view of its products. The company has also integrated its merchandising data support for more effective online product placement and promotion.
EmpireDirect.co.uk is the online division of Empire EC and has an annual turnover of more than £100m. It claims 50,000 users a day and says the average online customer spends £350 per transaction.
