Web beacons (also known as “clear GIFs” or “tracking pixels”) are tiny electronic image files that can be embedded within a web page or included in an e-mail message, and are usually invisible to the human eye. When used in our web pages, web beacons may tell us such things as: how many people are visiting our Websites, whether they are one-time or repeat visitors, which pages they viewed and for how long, how well certain online advertising campaigns are converting, and other similar usage data.
