Pop-up Ad
Also known as: pop-up, interstitial ad
A pop-up ad is an advertisement that appears on top of a web page, overlaying some or all of the underlying content. Pop-ups typically load in a separate layer or window, drawing the user's attention before or during their interaction with a site. The terms "pop-up" and "interstitial ad" are often used interchangeably, though "interstitial" can more broadly refer to any full-page ad unit that appears between content transitions, including in mobile app environments.
