Pop up ads are advertisments that show up in a new browser window. There's no one standard size for popup ads. Popup ads also vary widely in the amount of browser commands that show in the window. Pop-up ads are just one form of internet advertising used by advertisers to get web users' attention.
Pop-up and pop-under ads annoy many users because they clutter up the desktop and take time to close. However, they are much more effective than banner ads. Whereas a banner ad might get two to five clicks per 1,000 impressions, a pop-up ad might average 30 clicks. Therefore, advertisers are willing to pay more for pop-up and pop-under ads. Typically, a pop-up ad will pay the Web site four to 10 times more than a banner ad. That is why you see so many pop-up ads on the Web today.
