Usually, the first thing that comes to mind when you hear “web analytics” is streams of data and SEO. That's because everyone is concerned about getting traffic. But traffic is just the first step towards building a successful website. One of the most important aspects of any website is whether visitors actually do what you want them to do. Does your website design manage to guide users to the right information, so that they don't leave? Do they click on the action buttons? And more importantly, would your website perform better in its goals, if you made even minor structure and design changes. CrazyEgg is the simple heat map tool that gives you the answers to all these questions.
