I've been looking up resources for a presentation at the upcoming ASAE Technology Conference (you will be there, right?), and I had the opportunity to take a second look at CrazyEgg. When it was in beta - and free - it just provided heat mapping for any website (or really, any graphic you provided it), to help you understand where your audience's eyes would go first.
In the interim, they've expanded it into a full visual web analytics tool to help organizations increase conversion rates specifically (like, say, membership and conference registration perhaps?). It's not going to take the place of Google Analytics, but it provides an immediate, simple, visual way to understand what's happening - or more precisely, not happening - on your call to action pages. Sweet!
