Yahoo! may allow certain partners to include web beacons within pages served by Yahoo!. Yahoo! may also share portions of our log file data, including IP address, with these partners for analytics purposes. Your IP address may be used to estimate general location and other technographics (such as connection speed, whether you have visited Yahoo! in a shared location, and the device used to visit Yahoo!). These partners aggregate information about our advertising and what you see on the Yahoo! network of websites and then provide auditing, research and reporting for us and our advertisers. Currently, Yahoo! allows web beacons from and shares log file data with the following partners:
None of the personal information you have provided to Yahoo! as part of your registration is shared with our advertisers or our partners as part of these programs.
Applications and Widgets
Yahoo! may implement an application or “widget” from a third party on some of our properties that allows interaction or content sharing by Yahoo! users. These widgets, such as a Facebook “Share” or “Like” button, are visible to you on the page you visit. The company providing the widget may offer controls for you to manage the widget’s appearance and functionality. Your interaction with a widget typically allows the third party to collect some information about you through the third party’s web browser cookies or its registration information. However, in some cases, the third party may recognise you through its widgets and its cookies even when you do not interact with the widget. The privacy policies of the partners below should help you to better understand their data collection practices and controls that they make available to you when you interact with their services:
Most advertisements you see on Yahoo! websites are served by Yahoo!. We describe our own ad serving practices here. However, we also allow other companies to serve advertisements within our webpages. Most commonly, these are third party ad servers, ad agencies, ad technology vendors and research firms.
These companies may include a file, called a web beacon, within pages served by us 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, those companies can view, edit or set their own cookies, just as if you had requested a web page from their website directly.
As described in greater detail here, Yahoo! may customise some ads to users that it believes fit certain interest categories.. For example, “males interested in sports” would be a kind of interest category used to decide to show one ad about sports instead of an ad about something else. Yahoo! does not provide any personal 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 meet the interest category used to select the ad.
The following ad networks offer information, and in some cases an opt-out, on their respective websites:
