This has probably already been posted before but have you all tried crazyegg.com ? Wow...the heat maps are excellent! I can't believe some of the places people are clicking. Very good free product! Excellent!
Yes I tried crazyegg . It shows your most clickable links, you could raise CTR with this tool. Try, and you will not regret
Not only that, but it shows EXACTLY where on your page the person clicks - not just which links were clicked. For example, I had many clicks on an image that was not a link at all on my homepage. I've since changed that image to link to a page on my site.
