Do third party ad-servers serve advertising on Yahoo!? Can they use cookies?

Yahoo! does allow third party ad-servers to display advertising on our web sites. However, only a very small percentage of advertisements displayed on Yahoo! are served by third party ad-servers. Although Yahoo! does not share any personally identifiable information with third party ad-servers, they may use their own cookies to independently collect some information from you.

If you want to opt-out of receiving cookies from these networks you may be able to do so by visiting their web sites. Opting out of third-party ad-servers is your choice. It will not affect your ability to take advantage of any Yahoo! offering and may only affect the content of the ads you see that are served by that network. Please see Yahoo!'s Privacy Policy and related reference link about Network Advertisers and Third Party Ad-servers to learn more.
