Pop-up marketing itself is an excellent, low-cost and extremely productive marketing method¹. It makes it possible for the seller to link the customers’ interest to their site, as well as the buyers to receive the dynamic updates on the goods they intend to purchase. When the customer will receive a pop-up notification that the TV set he wishes to buy is offered at the online store he/she saw previously with a 15% price cut, one will undoubtedly use this chance and buy it. Taking into consideration the incredibly low price for the popups and their targeting, such an advertising method is a much-loved thing amongst the marketing departments of big online stores.
