Pop-up advertising itself is an excellent, affordable and also very effective advertising instrument¹. It allows the vendor to link the customers’ interest to their site, and the buyers to get the dynamic updates on the goods they wish to purchase. When the person will receive a pop-up alert that the TV set he desires to buy is provided at the online store he/she saw previously with a 15% price cut, one will undoubtedly use this opportunity and purchase it.
