Web Beacons
Web pages may contain electronic images (called a "single-pixel GIF" or "web beacon") that allow a web site to count users who have visited that page or to access certain cookies. Yahoo! uses web beacons in the following ways:

Within the Yahoo! Network

  • Yahoo! uses web beacons within the Yahoo! network of web sites in order to count users and to recognize registered users by accessing Yahoo! cookies.
  • Being able to access Yahoo! cookies allows us to personalize your experience when you visit Yahoo! web sites that are not on the yahoo.com domain (like Yahoo! GeoCities that has pages on www.geocities.com.).
Outside the Yahoo! Network
  • Yahoo! uses web beacons to conduct research on behalf of certain partners on their web sites and also for auditing purposes.
  • Information recorded through these web beacons is used to report aggregate information about Yahoo! users to our partners. This aggregate information may include demographic and usage information. No personally identifiable information about you is shared with partners from this research.
  • When conducting research Yahoo!'s practice is to require our partners to disclose the presence of these web beacons on their pages in their privacy policies and state what choices are available to users regarding the collection and use of this information. You may choose to opt-out of Yahoo! collecting and using this information for this research. Please click here to opt-out.

    Note: This opt-out applies to a specific browser rather than a specific user. Therefore you will have to opt-out separately from each computer or browser that you use.

HTML Mail
  • Yahoo!'s practice is to include web beacons in HTML-formatted email messages (messages that include graphics) that Yahoo! itself sends in order to determine which email messages were opened and to note whether a message was acted upon.
Yahoo! Points
  • Occasionally, Yahoo! Delivers messages may award you Yahoo! Points upon opening the message. Yahoo! Delivers messages include a web beacon that displays a message informing you of this award or inviting you to join Yahoo! Points if you are not a member.
  • Yahoo! Points may be awarded when you act on a banner or message offering points for visiting an advertiser's web site. The advertiser places web beacons on their page to allow Yahoo! to award you points for your visit if you are a Yahoo! Points member.

In general, any electronic image viewed as part of a web page, including an ad banner, can act as a web beacon. Advertising networks that serve ads onto Yahoo! may use web beacons in their advertisements.
