SplitTesting in WordPress

[Melanie]

Hi all,

A friend of mine, who owns a casino bonus site, is wondering how to improve his website for higher conversion rate. Well I suggested him split testing. With split testing I think he can benefit from the statistical data to decide or change his landing pages, and of course to be more profitable to him.

He is using WordPress and I recommended him Google Website Optimizer. BTW he wants to do A/B testing for his homepage. I also checked coinflipper which is also free, but not sure about this one...

Does anyone has other recommendations for him? Or is the Google Website Optimizer one of the best alternatives for the testing?
