A pixel tag (also called a web beacon or clear GIF) is a tiny graphic with a unique identifier, embedded invisibly on a webpage (or an online ad or email), and is used to count or track things like activity on a webpage or ad impressions or clicks, as well as to access cookies stored on users’ computers. We use pixel tags to measure the popularity of our various pages, features and services. We also may include web beacons in e-mail messages or newsletters to determine whether the message has been opened and for other analytics.
