Unfortunately, there are too many reasons why this site doesn't work for me. Starting the layout, the ads overload, the banner that's way too large for a site that should be accessed from a mobile device, etc.
My suggestion would be to look through our .mobi forum and check some of the demo sites by our NP members. You will pretty quickly see what they're doing different. It's starting with a more compact design, that's truly results driven and less convoluted with ads, etc.
Verdict: redesign needed.
