In the fast-moving whole world of digital marketing, advertisers are invariably testing new approaches to reach users. But some ad formats always deliver results year after year—Popunder visitors one of them.
Despite being less flashy than native ads or push notifications, popunder traffic still generate strong ROI for several verticals, particularly in affiliate marketing, software downloads, gambling, adult, and sweepstakes offers.
🧠 What Is Popunder Traffic?
Popunder traffic is the term for website visits generated through popunder ads—a kind of advertisement that opens in the new browser window under the active one when 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, after which they uncover the new page that was quietly loaded.
🔍 How Do Popunder Ads Work?
A user visits a publisher’s website.
A popunder script is triggered if the user clicks, scrolls, or interacts with all the page.
A new window or tab opens in the background while using advertiser’s landing page.
Once the person finishes browsing the original site and closes it, they start to see the ad.
This subtle approach makes popunders less annoying than intrusive pop-ups, while still grabbing attention in the right moment.
