Google Website Optimizer is a landing page testing tool that allows advertisers to split-test various page designs, layouts and content by splitting the traffic being channeled to the page versions from AdWords and then compiling reports to show which design feature is most effective at converting traffic into sales.
The Website Optimiser tool is now being promoted within Google Analytics. Users reviewing the Content overview reports for a site will now see a tiny image and link on the bottom-right inviting them to try the landing page split tester to improve their content effectiveness.
The poorly named product is not an actual SEO tool, but rather a PPC tool.
