Digital advertising keeps evolving, but not all ad formats disappear with time. One surprising survivor is the pop-under ad network. Despite being overshadowed by modern formats, pop-under ads still attract high-paying advertisers in industries like iGaming, dating, and travel.
Why? Because, unlike intrusive pop-ups or banner ads that often frustrate users, pop-under ads strike the perfect balance between visibility, user experience, and conversion potential. In this article, we’ll explore why leading brands continue to invest big in this “silent salesperson” of online advertising.
What Are Pop-Under Ads?
A pop-under ad is an ad format that opens in a separate browser tab or window behind the active one. Unlike pop-ups, which appear immediately and interrupt users, pop-unders remain hidden until the main browsing session is over.
This makes them a non-intrusive advertising format. Instead of disrupting attention, they wait until the user is free, ensuring that the message still gets noticed. That’s why advertisers often refer to pop-unders as the “silent salesperson.”
How Pop-Under Ads Work?
Before we explore why advertisers still invest heavily in pop-under ad networks, it’s important to understand how these ads actually work. Unlike flashy or intrusive formats, pop-unders follow a simpler, more user-friendly approach.
- Appear Behind the Main Window: Unlike pop-ups that block your screen, pop-under ads quietly open in a separate tab or window behind the main page.
- Non-Intrusive Advertising: Because they stay in the background, they don’t interrupt browsing, making them less irritating for users.
- Seen After Browsing: Users usually notice them only when they close or minimize their main browser window—so the ad appears at a natural pause.
- Great for Retargeting: Pop-unders act like reminders. Even after someone leaves a website, the ad is waiting for them, helping brands stay top of mind.
- Mobile Limitations: On small screens, pop-unders can sometimes be harder to view or interact with, since they open in a new tab or window.
In short, pop-under ads work by balancing visibility and user experience. They don’t interrupt people at the moment, but they still deliver strong exposure—one of the main reasons high-paying advertisers continue to use them.
Why Pop-Under Ads Attract High-Paying Advertisers
1. High Visibility Without Annoyance
User experience is critical in digital advertising. While pop-up ads can feel aggressive and increase bounce rates, pop-unders allow users to complete their browsing before showing up.
A HubSpot survey (2022) revealed that 73% of consumers dislike ads that interrupt browsing. Pop-under ads solve this issue, making them more attractive to advertisers who don’t want their brand associated with annoyance.
2. Better Conversion Rates Than Traditional Formats
When users notice a pop-under, they are often more relaxed and open to engagement. This leads to higher conversion rates compared to intrusive formats.
An iGaming brand compared banners with pop-unders in two markets. The pop-under campaigns delivered a 28% higher conversion rate and a 40% lower cost per acquisition (CPA).
For advertisers measuring digital advertising ROI, these results make pop-unders a profitable choice.
3. Resistant to Ad-Blocking Tools
Ad-blocking is a major challenge in online advertising. According to Backlinko (2023), more than 900 million people use ad-blockers, and over 32% of U.S. users block ads regularly.
Pop-under ads bypass this problem more effectively than display banners because they open in a new window. Leading pop-under ad networks also provide anti-ad-block features, ensuring that advertisers’ campaigns actually reach their audience.
4. Advanced Targeting and Customization
Modern ad networks allow advertisers to customize pop-unders with precision targeting, including:
- Device targeting (desktop, mobile, tablet)
- Geographic targeting (global campaigns or city-level targeting)
- Behavioral targeting (user interests, browsing habits, purchase intent)
This makes pop-under ads highly adaptable, ensuring advertisers can focus their budgets on audiences most likely to convert.
5. Strong Results in High-Paying Verticals
Not every industry invests the same way in ad formats. But there are a few sectors that consistently spend big on pop-under advertising and that’s because of its strong performance.
iGaming and Sports Betting:
These niches are super competitive and often restricted by tough advertising rules. That’s where pop-unders come in. They allow brands to discreetly promote offers like welcome bonuses, tournaments, and betting apps without breaking the flow for users. In fact, an iGaming campaign in New Zealand spent just $143.20 and earned $553.50—delivering a massive 286% ROI. That’s why betting companies keep investing in this format.
Online Dating Platforms:
Here in online dating platforms, privacy is everything. Pop-under ads work perfectly because they give users a private, non-intrusive way to discover new dating services. The result? More sign-ups and engagement—without the risk of embarrassing the user in front of others. A U.S. dating campaign with Clickadu proved this point by generating 281 conversions in just eight days, with a solid 77.6% ROI.
Travel and Tourism:
This industry thrives on timing whether it’s last-minute deals, seasonal discounts, or flight packages when users are actively planning trips. Pop-under ads slot in perfectly because they catch travelers right when they’re searching. For instance, a travel agency campaign used pop-unders to promote holiday packages and ended up with a 35% increase in bookings compared to the previous year.
Advertisers in these industries pay premium CPMs because pop-under networks deliver qualified leads that other formats can’t.
6. Scalable Traffic With Global Reach
Pop-under ad networks typically control vast global inventory, giving advertisers scale across markets. This is a major advantage for brands expanding internationally.
For Example: A U.S.-based dating app launched campaigns in Southeast Asia with pop-under ads. Within 60 days, sign-ups tripled thanks to geo-targeting and localized creatives.
For high-paying advertisers, scalability is just as important as conversion efficiency.
Pop-Ups vs. Pop-Unders: The Key Difference
To understand why advertisers prefer pop-under ads, let’s compare them directly with pop-ups:
| Feature | Pop-Ups | Pop-Unders | |
| 1 | Placement | Overlays on top of the current page | Opens behind the active window |
| 2 | User Experience | Interruptive, frustrating | Non-intrusive, discovered later |
| 3 | Engagement | Quick but often dismissed | Higher attention when noticed |
| 4 | Conversion Potential | Low–Medium | Medium–High |
This difference explains why pop-up ads are losing popularity, while pop-under ad networks continue to attract premium advertisers.
Why Pop-Under Ads Deliver High ROI? (Real-World Case Studies)
Pop-under ad networks are not just theory; they consistently deliver measurable results across high-paying industries such as iGaming, dating, gambling, and travel. Below are some verified examples that highlight how advertisers are achieving strong returns with this format.
1. iGaming Brand – Sports Betting Campaign:
A European sports betting platform tested multiple ad formats, including display, social, and pop-under ads. Despite generating fewer impressions than social ads, pop-unders produced the lowest cost per lead (CPL) and the highest ROI. This demonstrated how pop-under traffic can outperform even the most popular digital channels when conversions matter.
2. Dating Service – Mobile User Acquisition:
A U.S.-based dating app used pop-under ad campaigns with geo-targeting and age filters to reach the right audience. Over three months, user sign-ups increased by 22%, proving that discreet exposure through pop-unders is highly effective for driving engagement in competitive verticals like online dating.
3. Non-Mainstream Dating (Germany – HilltopAds):
A dating brand in Germany decided to test pop-under ads on HilltopAds. They put in $2,400, and the results were impressive—the campaign pulled in $6,792.84 in revenue, which means a 183% ROI. That’s nearly tripling their money just by choosing the right ad format.
4. Gambling (Japan – RichAds):
In Japan, a gambling advertiser ran a five-month campaign through RichAds. The effort brought in 1,196 new registrations and generated a massive $107,640 in revenue, with a 74.5% ROI. For an industry as competitive as gambling, that’s a clear sign of how powerful pop-under ad networks can be when targeted correctly.
These case studies confirm that pop-under ad networks remain one of the most profitable advertising formats. From dating apps to iGaming and travel platforms, brands across competitive niches are generating tangible ROI, higher conversions, and consistent growth by using this often underestimated format.
Why High-Paying Advertisers Stick With Pop-Under Ad Networks
In today’s ad ecosystem, high-paying advertisers prioritize results over trends. Pop-unders consistently deliver:
- Respect for User Experience → no disruptive interruptions.
- Higher Conversion Rates → users engage at the right time.
- Resistance to Ad Blocking → advertisers get real visibility.
- Scalability → global reach with targeted traffic.
For advertisers, this combination means stronger ROI, making pop-under ad networks a strategic investment, not an outdated relic.
Are Pop-Under Ads Good for SEO?
Directly, no pop-under ads don’t improve your SEO rankings. Search engines like Google don’t give any “boost” just because you use a certain ad format. SEO is mainly about content quality, site speed, backlinks, and user experience.
Indirectly, however, pop-unders can support SEO goals. Here’s how:
- Because they are non-intrusive, they don’t increase bounce rates the way pop-ups sometimes do. Lower bounce rates = healthier SEO signals.
- They help bring in targeted traffic from outside sources. More traffic and engagement can strengthen brand authority, which often correlates with better rankings over time.
- Pop-unders are ad-block resistant, so your campaigns are less likely to miss audiences, ensuring steady traffic to your landing pages.
In short, Pop-unders won’t directly boost your Google rankings, but they can protect user experience and bring in qualified visitors—which indirectly benefits SEO performance.

Still, many ad networks now optimize pop-unders for mobile with responsive formats to improve engagement.
5. Are Pop-Under Ads Blocked By Ad Blockers?
Pop-under ads are harder for ad blockers to detect compared to traditional pop-ups. Since they open in a separate window, they often bypass filters.

That’s why pop-under ad networks still attract high-paying advertisers in industries that demand performance. In a world of banner blindness and ad-blockers, the quiet effectiveness of pop-unders makes them more valuable than ever.
