Although this tool is certainly interesting, you much have an Analytics and AdWords account, as well as add a significant amount of "tracking" code to your site. It also seems evident that only sites with a great deal of traffic will have useful results. If you fit this category however, this could be a VERY useful tool. Watch the demo and bow before Google - a company that provides excellent, FREE software!

Great find SC! I'll have to check it out

Adwords would work MC okay right (having specific landing pages) and analytics tracking (basic and ecommerce) is fully integrated right? So I'd think that this would not be too hard for MC to make an option. The issue I see though is that, despite the result it gives you you still don't have control over 100% of yoru page to make any needed adjustments it suggests.

thanks SC.... really a great find. Hope it gives some good data
