Google Analytics gives you navigation link by link, but seeing a heatmap on your page leaves no doubt about how your visitors read your page and where they go. There's also a summary list of clicks on each link. Test different landing pages, ad placement, design layout changes, which content gets the most attention. Tracks Adsense ads--now you'll know not only which ad was clicked, but which position is most popular in an ad block.
They have a free membership which allows four sessions to be tracked, and of course, paid ones (with an annual discount, but you have to ask).
