Update Aug 28, 2007: links to examples fixed. Again.
If you just clicked over to look at Crazy Egg’s site, then clicked back, consider visiting there again when you’re finished reading this tutorial. If you’re as impressed with the way their site is put together as I am, you, or someone you know/work with, could probably benefit from Crazy Egg’s amazing click tracking visualization tools. Their prices sure make it easy to get started, so give it a consideration while you’re giving them traffic.
