Users may feel ambushed and distracted by pop-ups, which almost always consist of advertisements unrelated to the Web content the user is currently viewing. Pop-ups are commonly generated using JavaScript.įor many users, pop-up behavior is quite irritating. For browsers that support tabbed browsing, the pop-up may open in a secondary tab instead of a whole new window. To get the maximum amount of attention, a pop-up may also feature bright colors, animation and motion. This is achieved by making the pop-up open in a small secondary window, which becomes the active window. They are therefore meant to be as eye-catching as possible.

Pop-ups are frequently used by websites to advertise products or features.

Including a pop-up blocker in browser software helps it to work more effectively, because the browser knows when a website is attempting to open a new pop-up window and just ignores that request.Ī pop-up blocker is also known as a pop-up killer. This is why pop-up blockers were developed and have become a part of most Web browsers. Pop-ups are usually used by advertisers as a way to deliver ads, but they distract Web users from their experience and most consider them a nuisance.
