Yahoo! may allow certain partners to include web beacons within pages on the Yahoo! network of websites. Yahoo! may also share portions of our log file data, including IP address, with these partners for analytics purposes. In the event your IP address is shared, this information may be used to estimate general location and other technographics (such as connection speed, whether you have visited Yahoo! in a shared location, and type of the device used to visit Yahoo!). These partners aggregate information about our advertising and what you see on Yahoo! and then provide auditing, research and reporting for us and our advertisers.

Ad Networks and other Third Parties
Most advertisements you see on Yahoo! websites are served by Yahoo!. However, we also allow certain companies to serve advertisements and collect information within our webpages. Most commonly, these are third party ad servers, ad agencies, technology vendors, providers of sponsored content and research firms.
These companies may include a file, called a web beacon, within Yahoo! websites to provide auditing, research and reporting for advertisers. Because your web browser must request these advertisements and web beacons from the third party’s servers, these companies can view, edit or set their own cookies, just as if you had requested a webpage from their website directly. These companies may also use these cookies and web beacons to collect information on Yahoo! to deliver you customised ads on both Yahoo! and non-Yahoo! websites.
As described in greater detail in our Privacy Center, Yahoo may customise some ads to users that we believe fit an interest category – for example, male interested in sports. Yahoo! does not provide any personally identifying information to an advertiser when you interact with or view a customised ad. However, when you view or interact with an ad, the possibility exists that the advertiser will make the assumption that you qualified for interest category used to select the ad.
* Nielsen will share information about which ads you see with Facebook in an obscured form. If you are a logged-in Facebook user, Facebook will add your age and gender to your ad view details. Facebook will aggregate the combined information and share it with Nielsen for ad effectiveness reporting. To learn more about Nielsen privacy practices and opt-out of this sharing click HERE.
