These are notifications in text-graphic format that pop-up on the screen above other windows. They are sent to subscribers who have not banned them from being shown in browsers and mobile applications. They look like important messages, advertisements are inscribed natively, do not hide important information for the user.
This is an aggressive advertisement - a pop-up window below the active tabs. Unlike the first two formats, it does not give a person a choice - in any case, he gets acquainted with the contents of POP UNDER. If you learn to work with this format, you will get targeted traffic with minimal investment.
Banners are harmoniously integrated into the content, natively embedded in the visible area of the screen. The problem of "banner blindness" is bypassed. High loyalty, good click-through rate - up to 8 times higher than that of the usual format. Shows a very high result at a minimum cost.
