Pop-up promotions itself is a good, cheap and very efficient advertising method1. It permits the seller to link the buyers’ attention to their website, and the buyers to receive the dynamic updates on the goods they intend to buy. When the consumer will get a pop-up notification that the TV set he wishes to buy is provided at the online shop he/she checked out earlier with a 15% discount, one will certainly use this opportunity and purchase it. Taking into consideration the exceptionally small cost for the popups and their targeting, such a promotion and marketing tool is a favourite thing amongst the marketing departments of big internet retail stores.
