In the fast-moving arena of digital marketing, advertisers are invariably testing new methods to reach users. But some ad formats carry on and deliver results year after year—Popunder visitors are one of them.
Despite being less flashy than native ads or push notifications, popunder traffic still generate strong ROI for many 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 type of advertisement that opens in the new browser window under the active one when a user clicks or interacts which has a webpage.
Unlike pop-up ads that demand immediate attention, popunders remain hidden before the user closes or minimizes their current tab, after which they get the new page that's 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 using the page.
A new window or tab opens in the background while using advertiser’s web page.
Once the user finishes browsing the first 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.
🎯 Who Uses Popunder Traffic?
Popunder ads are specifically popular with:
Affiliate marketers
Download and software installers

These verticals utilize the high volume and low cost per visitor that popunder traffic provides.
