The revamped shopping channel is designed to enable easier comparison of prices of products such as electrical and household appliances, fashion, books, music and children's toys.
The site will also offer visitors additional decision- making support via professional product reviews, user product reviews, an "ask the expert" section and a discussion forum.
Rob Barnes, head of shopping at moneysupermarket.com, said he hoped the website's existing figure of five million visitors a month, combined with a strong Google marketing campaign, will broaden its appeal.
Last month, Moneysupermarket.com rejected a private equity approach, despite losing half its value since floating on the stock market last year.
The website's loss in value coincided with the arrival of competitors such as Tesco's Tescocompare.com, and the prominence of rivals including Confused.com.
Last month, MSN selected Moneysupermarket.com to provide a range of information tools for its MSN Money site.
