CrazyEgg: Getting a heatmap for your site for free

The idea behind CrazyEgg is simple – show the hotspots where users click on in a site. This information is not the same as popular pages; instead this is practical information about how and where people click on your site. More importantly, CrazyEgg’s approach lets you understand the difference between where you want your users to click and where they are actually clicking.

Here is a heatmap of my photoblog at www.dirkpaessler.com (click the image to zoom in):

Emprise Javascript Charts is a Javascript library that draws charts in web applications without any graphics processing on the server and without Shockwave (like e.g. Fusion Charts).
