Popup banner

A popup banner is a banner that appears suddenly in the foreground of the visual interface, usually in a clearly delimited window. Popup banners are called like this because they “pop up” on the page, interrupting the user with a promotional message. They are usually used for offering discounts and for promoting new products or services, but also for prompting users to click on the banner for more information on a service or product. Popups can also be used for opt-in forms.
