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.
