A difference I found between Google and Yahoo! is what the page offers once you've started your search. Once I've entered my search in Yahoo, I can access the options for my search such as images and recent news. Google offers this same feature, but I enjoy the layout much better on Yahoo!. There is a lot less clutter on the page and I find it easier to navigate. The most helpful and my favorite feature of them all is the moving search bar. As you scroll down the page on Yahoo!, the search bar follows you at the top of the page, allowing you to search from any point.
