I just wanted to share the results gained from using Google new Website Optimizer Tool. I set up an experiment on www.voodoochilli.net
the experiment consisted of a change of graphic, simply increasing the brightness of the register button slightly to make it a more prominent feature to see if more people would register on the site.
The results were quite remarkable, at 108% over the original graphic.
Voodoochilli isn’t about making money, but I can imagine that this tool could be very effective in optimising content for that purpose.

Please note I have blurred some of the results as I don’t want competing sites to have complete access to this data.
Nice job. One thing to keep in mind is best testing practice is to let the experiment run at least 2 weeks before declaring a winner but it’s hard to imagine Combo1 not winning.
Yes I thought about that too, I would have let it run for longer but the results were so strong I thought I might as well go live with it. By the way, the combination1 was only a subtle change, so it just goes to show that small changes can make a big difference.
Oh, thanks for this Info. I will try it.
