Pop-up marketing itself is a good, affordable and really productive advertising tool¹. It makes it possible for the seller to attach the buyers’ attention to their website, and the buyers to get the dynamic updates on the goods they want to buy. When the consumer will receive a pop-up alert that the TV set he likes to buy is available at the online store he/she checked out earlier with a 15% price cut, one will definitely use this possibility and purchase it. Taking into consideration the extremely low cost for the popups and their targeting, such a promotion and marketing tool is a favorite thing amidst the marketing teams of huge internet retail stores.
