Ad Serving

Yahoo! displays ads both on our network of owned and operated websites, such as the sites on the domain and sites like and others (see our Acquired Companies page for a list of other domains where Yahoo! may serve ads) and on non-Yahoo! websites. Yahoo!’s ad network includes the Yahoo! Network and Yahoo! Search Marketing. Yahoo! serves display ads, also known as graphical ads, which appear as images, animation or video. Yahoo! also serves text ads that appear as text links. Yahoo!’s Right Media Exchange and, in some markets, its APT technology platforms (“the Exchanges”) provide the means for advertisers, agencies, publishers and ad networks to manage their advertising business.

When you visit one of Yahoo!’s websites, or a non-Yahoo! website where Yahoo! may serve ads, ads that you see may be suggested by Yahoo! based on various factors such as the content of the page on which they appear, information you provide such as your gender, age or location, what your friends or contacts recommend to you, or based on your other interests. Yahoo! may use information you provide, including personally identifiable information, to tailor ads when you are on one of our websites or using one of our services. Yahoo! may also analyse your use of our products and services and your engagement with the ads we show you. You can control Yahoo!’s use of this information for ad selection and improving the effectiveness of the Exchanges by opting out.

NOTE: The Blue Lithium ad network has been integrated into the Yahoo! Network and the domain previously used by Blue Lithium ( is no longer used to serve ads as of July 1, 2010. While ads are no longer served through this domain, the domain will remain active in order to honor privacy choices made on the Blue Lithium platform. If you would like to update your Yahoo! Network choices, please visit our Opt-Out.
