You spell "conversion" incorrectly in two different ways and your grammar is poor ("Why noone...").
If I were you I'd get the site redesigned, preferably by a professional web designer.
Maybe slim the main page down to your banner, a tag-line saying what the product is and a "Try It Now" button. I don't want to sign up for anything; why not let me demo it on your site in real-time?
And where's the initial Wow? There's a heatmap picture on the main page but nothing happens when I click it. Why not have the image work as a heatmap too?
Sorry to be so negative, but maybe you'll get better results if you fix some or all of those things?
Also, I did want to see how it actually worked, but I don't want to sign up and install stuff for that...so that's why I wanted a live demo.
I think you should drop the "completing with Google Analytics" angle too. Even if it's true that you're better, no-one will believe it. Why not show how you integrate with it instead? If people are using both and realise themselves that they only need your product, then that's good enough.
We really should put a little more effort into this project.
I agree about "noone", but I don't think the website can be called awful. It's certainly quite pretty.
