Updating its AdSense ad policies, Google has stopped permitting the use of such ads on pop-under pages. The update has been made with a belief that these ads do not provide a good user experience.
“Pop-under ads can be annoying as well, as they will “pop under” your window, so that you don’t see them until you minimize your browser. We do not believe these ads provide a good user experience, and therefore are not suitable for Google ads,” the company explains through its official blog post.
It stated that towards simplifying the policies, Google is no longer permitting the placement of Google ads on pages that are loaded as a pop-up or pop-under.
Additionally, it does not permit Google ads on any site that contains or triggers pop-unders, regardless of whether Google ads are shown in the pop-unders.
So, now to stay in Google’s good graces and continue displaying Ad Sense ads, it’s best to refrain from using pop-unders.
Now, it’s the responsibility of individual site owners to ensure their site is compliant with Google’s policies. And, if found to be in violation of Google’s ad policies, the company may ban the use of AdSense ads on a site with or without warning.
