CNBC started promoting their new website in the October – November timeframe and launched it on Dec 05, 2006 (according to archive.org). In the next 10 months traffic jumped 139%. 334,000 new readers have been added to their previous installed base of 200,000 readers.
So what does this mean?
CNBC is a news portal where content is expected to be king. Yet new design has given them access to more customers than what they originally had. If a design insensitive demographic has reacted this overwhelmingly to a free news portal imagine how they’d react to bad design coming from a commercial eCommerce site?
