Widgets

A widget is any part of a user interface that can display information and interact with a user's actions. A widget can be configured to do almost any small information-centered task on a website.

One such type of widget is used for tracking visitors to a website. It gathers information on visitors such as their geographical location, what website they visited last, and any external links they may have clicked on to leave the website.
