Definition:
A pop-under is a type of digital advertisement that appears in a separate browser window, located behind the page the user is viewing. Unlike pop-ups, which open above the current window and can interrupt the user’s experience, pop-unders remain hidden until the user closes or minimizes the main browser window. This approach makes them less intrusive, as they do not distract the user from their current activity. However, due to their hidden nature, pop-unders can be perceived negatively, as some users associate them with invasive practices or malicious software.
