From the Inside Adwords blog -
A tool with a great potential for non-adwords users / webmasters too.
Over the coming weeks we'll be testing a new tool called the Website Optimizer that can help you find out which content will convert best on your site. Whether you define a conversion as a purchase or a newsletter sign-up, Website Optimizer allows you to experiment with different headlines, copy, and images on your site in order to find out which combination results in the most conversions. You can use this tool on your landing page or any page that represents a conversion.
