Today at the SMX Advanced conference in Seattle, Google announced the Website Workout contest to help businesses pump up their websites. Any U.S. business can enter to have a webpage optimized for free by Google’s team of consultants to boost sales, sign-ups or leads. Interested businesses can enter the contest by visiting the Website Optimizer Workout site.

In the coming weeks, Google will select four of the businesses that enter. Using Google Website Optimizer, Google’s free website-testing tool, the consultants will then work with the winners to test which combination of text, images, graphics and other content drives the most business.

Website-owners need not enter the contest to use Website Optimizer, however: the tool is free and open to anyone who wants to fine-tune a website. Anyone can sign up for the product at Google Website Optimizer.
