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
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.
