Defence-p push notification.

Pop-up advertising itself is a very good, cheap and really successful advertising method¹. It permits the seller to link the customers’ interest to their website, and the customers to receive the dynamic updates on the goods they wish to buy. When the person will receive a pop-up notification that the TV set he likes to buy is available at the online shop he/she saw previously with a 15% discount, one will undoubtedly use this chance and buy it.

However, due to its huge resources consumption, as well as some errors that may be crucial for some kinds of users, Defender is oftentimes turned off by the users, so its use is probably impossible.
