A web bug is an object that is embedded in a web page or email and is usually invisible to the user but allows checking that a user has viewed the page or email. Common uses are email tracking and page tagging for Web analytics. Alternative names are web beacon, tracking bug, tag, or page tag. Common names for web bugs implemented through an embedded image include tracking pixel, pixel tag, 1×1 gif, and clear gif. When implemented using Javascript, they may be called Javascript tags.
