The site also offers more video and an easier way for advertisers to customize their messages.
CNET.com has been known for years as a resource for technology product reviews from CNET editors. The relaunched version adds a blog network with reviews and user opinion aggregated from across the Internet.
Behaviorially targeted advertising is part of the new design. Based on what users are searching for, manufacturers will be able to connect with them by offering relevant information within the comparison shopping process.
In addition to its traditional focus on tech products, CNET is adding appliance and kitchen gadget reviews, covering such products as built-in ovens, dishwashers, microwaves, refrigerators, small appliances, stoves and ranges, and washers and dryers. The company said the increasing sophistication of these products, often with computer displays, makes this a natural addition.
A new CNET Archive feature will offer information on used tech gadgets, such as digital cameras and high-definition TVs, while CNET Downloads will provide access to more than 1 million archived products, including software and games.
CNET Networks, a division of CBS Interactive, was acquired by CBS for $1.8 billion in June.
