In the fast-moving realm of digital marketing, advertisers are always testing new approaches to reach users. But some ad formats carry on and deliver results year after year—Popunder visitors one of them.
Despite being less flashy than native ads or push notifications, pop under ads still generate strong ROI for a lot of verticals, especially in affiliate marketing, software downloads, gambling, adult, and sweepstakes offers.

🧠 What Is Popunder Traffic?
Popunder traffic identifies website visits generated through popunder ads—a kind of advertisement that opens inside a new browser window under the active one whenever a user clicks or interacts having a webpage.
Unlike pop-up ads that demand immediate attention, popunders remain hidden prior to the user closes or minimizes their current tab, at which point they get the new page that has been quietly loaded.
🔍 How Do Popunder Ads Work?
A user visits a publisher’s website.
A popunder script is triggered in the event the user clicks, scrolls, or interacts with all the page.
A new window or tab opens in the background while using advertiser’s squeeze page.
Once the consumer finishes browsing the initial site and closes it, they see the ad.
This subtle approach makes popunders less annoying than intrusive pop-ups, while still grabbing attention with the right moment.

Popunder ads are specifically popular with:
Affiliate marketers
