Look at this!
Basically is records visitors to your website as a video so you can play it back and actually see how they navigated around the site, what they clicked on, heat maps etc.
I installed it on one of my sites and it actually works! its very scary. You can see exactly how they moved around your site, what links they click, how long they stay on a particular site, their navigation paths, everything!
It is FREE at the moment to sign up and what you get is 100 recordings a week. You tell it how many visitors you are currently getting, how many page views a visit etc and it picks the optimum recording frequency. Obviously this doesn’t record everyone but it gives you a fair idea of what is going on.
Amazing for anyone trying to optimize their website performance to improve web usability, conversions and revenue.
