Crazy Egg is a unique service that provides graphical and text analyses of visitor behavior on your site.
Yes, you can simply count page views, or IP addresses, but can you really use this information? You need to know where your visitors are clicking so that you can fine-tune your site's performance. For example, if you are running an ad campaign that isn't earning any money, it could be due to the placement of the ads. You can use Crazy Egg to experiment with this positioning until you find the right spot to improve the ad's performance.
