What is a popunder page?
A popunder is a pop up that loads in the background underneath a web page. This is a highly effective form of internet advertising because contrary to a pop up, a popunder fully loads in the background and is seen when the visitor has finished viewing the original web page. Popunders have been given a lot of press lately due to their effectiveness. You most likely have seen this type of advertising on high traffic websties in your journeys on the internet.
