ClickTracks are fighting back. For those unfamilar with ClickTracks, it is a visual statistics analysis tool aimed at marketers. It features overlayed data, so you can quickly see which parts of your site are working, and which parts aren’t. ClickTracks are now offering a free version. I find this tool especially great for testing usability and the marketing effectiveness of new design layouts.
The free version is called Appetizer. Give it a whirl.
