Pop-up advertising itself is an excellent, low-cost and also very successful marketing tool¹. It enables the vendor to link the customers’ interest to their site, as well as the customers to get the dynamic updates on the goods they want to buy. When the customer will receive a pop-up alert that the TV set he wishes to buy is available at the online store he/she saw earlier with a 15% price cut, one will certainly use this chance and buy it.
