I have a few questions. Is heatmap - http://wordpress.org/extend/plugins/heatmap/ - still a good tool to track mouse movement on a wordpress blog site that uses adsense? Do adsense policies permit this? If heatmap isn't still used / valid with latest wordpress, then is there another tool that someone can suggest? I just want to get an idea of what the "hot spots" on my site are, where people click, etc. Thanks!
