These guys over at CrazyEgg have a very cool service that you can use to get some visuals on which links have been clicked and how many times and so forth. The nice thing is that it does it by individual link as well, even if you have multiple ones that point to the same resulting item. The most visually impactive feature is the heatmap that shows you where people focus their mouse clicks on. The resulting graphic is pretty impressive. You can use this information to determine how well a site design works or for determining how well a new look might work with a select group of users. I’m going to have to plug this in to see what it shows for my site. I’ll post some screenshots later when I have a chance to put it in place.
