AdWords advertisers are rejoicing over the release of a new tool released by Google yesterday named Google Website Optimizer. The tool allows you to test different landing pages against each other and reports back to you which pages and content is working best for your campaign.
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.
There is a demo here and this is a sample report:
