Webpages and HTML emails may contain a small snippet of code called a web beacon. In their simplest form, web beacons allow a website to transfer or collect information through a graphic image request. Websites may use web beacons and cookies for many purposes, including site usage analytics, advertising auditing and reporting, and content and advertising personalization.
Yahoo’s Practices Regarding Web Beacons
Yahoo may collect information through web beacons about your web browsing activities such as the address of the page you are visiting, the address of the referrer page you previously visited, the time you are viewing the page, your browsing environment and your display settings. We may use the information we collect through web beacons:
- To understand traffic patterns and the number of visitors to the branded Yahoo network of websites, websites within the Yahoo Network Plus, and other non-Yahoo websites that we partner with.
- To understand how you use and interact with Yahoo products and services, including, but not limited to, the use of Yahoo Mail outside of a browser-based experience.
- To improve Yahoo products and services.
- To optimize your browsing experience.
- To provide anonymous individual and/or aggregate auditing, research, modeling and reporting for our advertisers and other partners. No personally identifiable information about you is shared with our advertisers and other partners as part of these services.
- To offer Yahoo Web Analytics.
- To provide you relevant advertising and content.
- To determine which email messages sent by Yahoo, or its agent, were opened and to note whether a message was acted upon.
