What Are Popunder Ads? How They Work and Why They're Still Effective in 2025

#Ads tips

Popunder remains one of the most effective and high-performing ad formats in 2025 — and it’s not going anywhere. Despite being around for years (and often underestimated), it still drives reach, traffic, and conversions for advertisers across the globe. In this article, we’ll walk through why popunder ads still perform, how to use them right, and when they deliver the best ROI.

What Is a Popunder, Anyway?

If you haven’t used popunder ads before, here’s a quick overview.

A popunder ad opens in a new browser tab, behind the current window. The user doesn’t have to click for the ad to open — they’ll eventually see your landing page when they close or switch tabs.

For advertisers, this means guaranteed visibility. Your offer is shown no matter what — even if the user didn’t engage initially. And that’s exactly what makes the format so powerful.

Why Advertisers Still Choose Popunders

Let’s keep it simple — popunder traffic works. It solves the exact problems advertisers care about: launching fast, reaching large audiences, getting first conversions quickly, and validating whether an offer has real potential.

According to network data, popunder campaigns in verticals like adult, sweepstakes, VPNs, and utilities still show higher average CR than most other formats. 

Let’s break down the key benefits of the format:

1. Fast Launch

All you need is a landing page and a few basic settings — no creatives, no banners, no funnels, no long approval process. You can go live in under an hour.

2. Users Always See It

Users see your offer no matter what — no clicks required. You don’t need to wait for engagement; the format ensures the page is shown.

3. Adblock-Resistant

Popunder ads bypass most standard adblockers. Your campaigns reach even those users who don’t normally see ads — especially valuable in GEOs with high blocking rates.

4. Budget-Friendly and Test-Ready

Popunder campaigns are easy to test without overcommitting your budget. The format allows you to quickly evaluate performance, optimize early, and double down on what works — whether you're testing new GEOs or offers.

5. Easy to Scale

Once you’ve found a winning combo, popunder ads scale well — no drop in traffic quality. That’s especially useful when expanding into new GEOs or scaling up successful offers.

If you haven’t tested popunder yet — now’s the time. Start with a small budget, see how your audience reacts, and scale what works.

In What Cases Should You Use Popunder?

Wondering if popunder is the right format for your next campaign? Here’s a quick rule of thumb: if you want fast testing, broad reach, and quick results — without investing in complex creatives — popunder is a great option.

It performs especially well in the following scenarios:

  1. Need for Fast Reach

Launching a new campaign or entering a new GEO? Popunder helps you reach a wide audience fast — no other format delivers volume this quickly.

  1. Fast Decision-Making Offers

Popunder ads thrive in verticals where users make decisions on the spot. Think:

• Dating

• Adult

• Subscriptions & sweepstakes

• VPNs & utilities

• Mobile apps

• Gambling & casual games

In these verticals, speed matters. Users don’t have time to scroll through long funnels or compare offers. They either act — or bounce.

Popunder gives you that critical moment to grab their attention. If your headline and first screen are relevant, they stay — and convert.

We regularly see stable CRs and low CPAs for popunder campaigns in these niches.

  1. Quick Launch in a New GEO

Entering a new market? Popunder helps you gather first-party data fast — without needing a full creative setup. You’ll see how users behave and adapt accordingly.

  1. Supporting Campaigns 

Even if you're already running campaigns in other formats, popunder can help boost your reach — especially when you need quick volume, want to scale a winning offer, or test new GEOs alongside your main traffic sources.

How to Maximize Conversions with Popunder: 5 Field-Tested Tips

Popunder is simple on the surface — but just like any format, it comes with nuances. Below are proven techniques used by top advertisers to drive conversions, not just impressions.

1. Localize by GEO — In Targeting and Messaging

Adjust your bids per GEO — but also adapt the creative itself. Some countries respond better to urgency; others to personalization.

Even small tweaks like “Offer for users in India” or “Today only in Turkey” increase engagement by building trust.

2. Don’t Overdo Frequency

One impression per user per day is enough. This lets you avoid user fatigue while still getting quality exposure.

3. Optimize for Speed

If your landing page takes more than 2–3 seconds to load, the harsh truth is — users will close it. Test load times in your target GEOs, remove heavy assets, and compress where needed. A small delay can cost you lots of conversions.

4. Make the Funnel as Short as Possible

In popunder traffic, long funnels don’t work. The faster a user sees what’s expected and how to act — the better.

What works:
• Lead form on the first screen
• Only essential fields (email or phone)
• Clear CTA buttons
• No distractions like popups, sliders, or dropdown menus

Simplicity = higher CR.

5. Track Behavior, Not Just CR

Pay attention to bounce rate, time on page, scroll depth. If users leave in under 3 seconds, your trigger or hero section likely isn’t relevant.

Test variations, restructure, or change the visual hierarchy — small shifts can double performance.

Real Example: 150% ROI from Popunder Only

Let’s look at how this format works in a real campaign.

Offer: Dating
Traffic source: ClickAdilla
GEO: Germany (Tier-2)
Ad format: Popunder only
Test budget: $64
Net profit: $192.26
ROI: 160%

The advertiser used a Smartlink, which made it easy to test multiple offers within the same niche. The main advantage here is that you don’t have to guess which specific offer will convert — the algorithm automatically redirects traffic to the best-performing ones.

The setup was simple: a minimal landing page with a strong trigger on the first screen. The headline was localized for the GEO, and the copy was tailored to the local audience.

Results: CR above 9% and ROI over 150% within the first week.
No banners, no complex funnels — just popunder traffic and clear messaging.

Initially, the campaign was launched without targeting devices, languages, or specific time settings. After gathering some data, the advertiser:

  • split the traffic into separate campaigns for mobile and desktop
  • blacklisted underperforming sources

The result: traffic volume slightly dropped, but the CR increased by 27%. Which means more registrations and higher profit — with the same budget.

For Publishers: How Popunder Helps Monetize Your Traffic
