Website Optimizer Rocks!
Multivariate Analysis is essential to do online marketing well.
Your gut cannot predict the nuances of the internet and your users, but by experimenting with different combinations of graphics and copy you can find the most effective conversion tactic.
It’s not trivial to set this up normally, but Google have done it again with their tool – website optimizer. It just makes something that is quite challenging for people without a statistics PhD into something that anyone who can follow basic instructions can implement.
Basically Google take care of the complexities of implementation and the mathmatical statistics leaving you to focus on refining your campaign.
