Optimizely user review

This is a great tool if you want to do A/B testing of landing pages. The latest version allows you just to put in urls of your pages which can serve as 'A' and then Optimizely will make a second version whcih you can amend according to what you are attempting to test. My team uses this tool on an increasingly regular basis. In fact we built our latest site based on the results we got from it. Great tool!
