What Is Popunder Traffic? A Guide to One of the Oldest & Still-Effective Ad Formats
In the fast-moving arena of digital marketing, advertisers will almost always be testing new methods to reach users. But some ad formats continue to deliver results year after year—Popunder readers are one of them.
Despite being less flashy than native ads or push notifications, popunder ad still generate strong ROI for several verticals, specially 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 in the new browser window beneath the active one when a user clicks or interacts which has a webpage.
Unlike pop-up ads that demand immediate attention, popunders remain hidden until the user closes or minimizes their current tab, at which point they uncover 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 the page.
A new window or tab opens in the background using the advertiser’s landing page.
Once the consumer finishes browsing the original site and closes it, they begin to see the ad.
This subtle approach makes popunders less annoying than intrusive pop-ups, while still grabbing attention at the right moment.
