If you want to see improvement in your site, then multivariate testing is a must. Multivariate testing is very complex and not something that you should do on your own. Multivariate testing will take a page and change many of the different elements on the page and show the different variants to viewers randomly. We then gather data on how which variations encouraged viewers to accomplish the chosen goal more. You will need to have goals setup in google analytics first before we can do any testing, unless you would like to test for bounce rate or time on page.
