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 in.geocities.com.).
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 count how many messages have been opened and acted upon
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.
