In the fast-moving whole world of digital marketing, advertisers are invariably testing new approaches to reach users. But some ad formats continue to deliver results year after year—Popunder traffic is one of them.

Despite being less flashy than native ads or push notifications, popunder ads still generate strong ROI for most verticals, particularly in affiliate marketing, software downloads, gambling, adult, and sweepstakes offers.

🧠 What Is Popunder Traffic?

Popunder traffic describes website visits generated through popunder ads—a kind of advertisement that opens in a new browser window within the active one each time a user clicks or interacts with a webpage.

Unlike pop-up ads that demand immediate attention, popunders remain hidden before user closes or minimizes their current tab, at which they get the new page that was 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 an individual finishes browsing the initial 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 at the right moment.

🎯 Who Uses Popunder Traffic?

Popunder ads are specifically popular with:

Affiliate marketers

Download and software installers

Adult traffic campaigns

Sweepstakes and giveaways

Casino and betting platforms

Crypto offers

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

CPV (Cost Per View): What you pay per opened popunder

CTR (Click-Through Rate): Percentage of users who click after seeing your page

💡 Best Practices for Popunder Campaigns

Use a Fast-Loading Landing Page: Speed matters—users may bounce when the page takes too much time.

Target by Device & GEO: Mobile and Tier 3 countries often provide best ROI.

Test Different Offers: Some verticals perform better than others; always A/B test.

Use Frequency Capping: Avoid annoying users by limiting how often they see your ad.

Optimize for Bounce Rate: Add compelling headlines or countdowns to lessen instant exits.

Popunder traffic may appear old-school, but it is far from outdated. For performance marketers, it remains a high-volume, cost-effective traffic source—perfect for testing offers, scaling campaigns, or reaching users inside a less competitive ad space.

As with any ad format, success depends on targeting, squeeze page quality, and gives relevance. Done right, popunder ads can quietly drive big results.
