I missed this one last month when I was travelling, however it’s still worth mentioning for those who may have also overlooked it.

Interesting multivariate analytics tool from Google.

“The Website Optimizer allows you to test changes in the website content of your pages in order to determine what will be most effective in getting conversions. You choose what parts of a page you’d like to test — headline, image, promo text – and we’ll run an experiment on a portion of your site traffic to determine which content on your site users respond to best. When we’ve collected enough data, we’ll provide you with reliable reports and a suggested course of action in order to optimize your site for maximum business results.“

This tool works with Google Adwords and Google Analytics. By testing various combinations of page elements, such as headlines and text, against each other, you can determine which landing page results in the most conversions.

Software like this can be expensive and tedious to use, but this system is free, and appears relatively straightforward.
