Google and Yahoo sign search partnership

Yahoo has partnered with Google in an advertising pact. The three-year deal means Google will help power Yahoo's search engine and provide it with advertisements. Google will pay Yahoo a percentage of revenue from ads, and Yahoo will pay Google for requests for word or image search results. Yahoo, which is already partnered with the third of the top three search engines -- Microsoft's Bing -- said the new Google deal gives Yahoo "additional flexibility to choose among suppliers of search results and ads." Having three different search engines at its disposal "really improves search," Yahoo CEO Marissa Mayer said, providing the company "greater stability as well as choice and a better user experience." Yahoo has discretion to select which search queries to send to Google and will not have to send a minimum number.
