The best thing about this tool, has got to be that it keeps track of all your data so you can see which variations are converting well or not as such - which helps in future experimentation! However I would like more ways to segment my users into different groups. This way i could further analyse where they're coming from so maybe tailor better content recommendations etc. They have some great tutorials online too if anyone wants them (as part of their 30 day free trial). Just give it go :) It took me 5-6 days but then again thats because we had quite an extensive list of features already built up before using thirve optimize to begin with :p And after doing everything mentioned above its probably less than 2hrs now since last time our website was live!
