The goal of these ads is to capture the user’s attention and encourage them to click through to the advertised product or service.

While pop-ups can also serve other purposes, such as displaying security alerts or site notifications, their most common and recognized use is to deliver advertisements. This association is widespread among users, many of whom have experienced pop-up ads during their online activities and may even use pop-up blockers to enhance their browsing experience. Hence, when thinking about pop-ups in web browsing, the primary connection is indeed to advertising windows.
