This article explains the differences you may see in your search results due to the Yahoo! and Microsoft Search Alliance.

Most of the things you see on the typical Yahoo! Search results page will not immediately change as a result of this alliance. What will change is that the basic search listings and ads will be provided by Microsoft instead of by Yahoo!.

Yahoo! will continue to enhance the search result listings as we do today. A few examples of this are:

1. Providing you with rich results that display the most relevant information from our rich content properties, as well as other great product, local, entertainment, reference, social and tech sites.
2. Showing specific results from vertical search products, like Yahoo! News.
3. Providing handy tools on the left-side of the page, such as SearchScan, site filters that help you refine and explore the search results more easily, and "Related Search" term suggestions to help you refine your search when the results aren't quite what you were looking for.
