Before we attempt to answer the question of the title, it is first best to define the difference between a pop-up and a pop-under ad.

Pop-ups act just like they are called, the just pop up everywhere on the webpage being opened and used by a visitor. They are very intrusive, they could overwhelm the page for there are a lot of them coming out at that same time and they are just plain irritants.

The pop-under ads act as they are called, they pop up underneath the webpage. Basically, they appear when the page is about to be closed. So they do not intrude on the use of the page and they are less likely to intrude on the personal internet space of the user. Because they are less intrusive they are less likely to irritate. Also, usually only one pop-under appears in one page and therefore does not overwhelm.

So, how come, if the online advertisements are really irritating, the pop-under is working well compared to the pop-ups? The answer is right there in the definition, they are less intrusive, that’s why. They do not intrude on the time and space of the internet user. Because they are not intrusive they are less likely to irritate. And because they are less likely to irritate, the visitor’s curiosity would be stimulated, and there is more chances for the visitor to open the ad window and find out more about it.

The psychology of the internet user is the one being considered in this advertising method. It has been shown that an irritated user is more likely to abandon a page if they see banners and pop-ups. As pop-unders are also easier to close, the internet user is given a better option to close or open the window. It is this politeness and respect to the internet user which makes the pop-under advertising method the hottest method being used on the internet today.

As more and more webmasters are seeing the perfect solution to the problems caused by the pop-ups and the banners, they now have a better chance to get the information out and read by the traffic which they need to boost their sales.

Another thing that is important to mention. Many pop-up ads now ride on viruses, Trojans and malware so it has really caused a lot of problems for many computer users. It did not help that the top anti-virus software like Kaspersky headlines their software with words like ‘effective pop-up ad blocker.’ People have been complaining that unscrupulous marketers are using the viruses to keep the pop-up ads appearing. Worse, they are very difficult to close, not like the pop-unders.

In truth, the pop-under, pop-ups and pop-overs are really great marketing methods which will get that information out to the public. It is just that the use of the pop-ups have been abused that it has invaded many systems and webpages that caused many users to get paranoid when they see them opening in a page.

The pop-under ads are more respectful and are discreet, a total opposite of the pop-ups.
