Popunder Ads: Drive Conversions Without Driving Users Away

A popunder automatically opens in a new tab behind the user’s active window. Since it never interrupts the browsing session, it’s considered a less intrusive ad format that doesn’t harm the user experience (UX). 

The challenge, however, is that the landing page advertisers want to display is often unrelated to the content on the publisher’s website. This inconsistency can turn users off, so it’s important to focus on usability of popunders  to generate a stable income.

Why Usability Matters in Popunder Advertising

The user only sees the ad’s landing page after they close the main browser tab. So, first impressions are everything.

A clean, appealing layout guarantees that your message lands instantly. If the page promotes the offer effectively, clicks and conversions will naturally follow. Otherwise, cluttered pages, poor mobile design, or loading delays will kill engagement before it even begins.

Impact of the Format on User Behavior

Popunders are a relatively casual ad format. Native ads, which are embedded in the content, are even more subtle. Still, popunders don’t break the user’s flow, since they appear quietly in the background. In comparison, push ads are far more distracting.

As pop ads are less intrusive, users are more willing to engage with them. However, their attention span is limited: they won’t spend time trying to figure things out. To earn with popunder, advertisers should present a crystal-clear offer and get straight to the point.

How Popunder Affects Website Trust

A clean and professional-looking popunder builds trust. In contrast, a landing page with aggressive widgets, typos, or sketchy wording immediately raises red flags.

To create a sense of legitimacy and security (which is vital for iGaming traffic), invest in high-quality visuals. Users will spend more time on a beautiful landing page, and their time is your most valuable asset on the path to effective popunder campaigns.

Balancing Revenue and Usability

A great user experience of popunders doesn’t have to conflict with profitability. Advertisers can get the best of both worlds, boosting lead generation and ROI and preserving the UX. Below, we discuss what you can do.

Set Ad Frequency and Choose Optimal Timing

If you use Kadam, you can set the popunder frequency right under your campaign’s name in your dashboard. The best practice is to stick to 1–2 impressions per user per day. 

You can also schedule when your ads are shown and adjust popunder timing. In some regions, conversion growth spikes in the evening or on weekends.

Know When Popunders Become Annoying

Keep a close eye on metrics like time on page, conversion to clicks, and bounce rate. If users are closing your landing page within 2–3 seconds, it might be time to rethink your design and strategic approach.

Minimize Negative Impact of Popunder Ads to Retain Users

To make sure that your pop traffic source doesn’t feel intrusive, focus on two key areas: 

• excellent design;
• content relevance.

First, ensure your Call-to-Action (CTA) button is prominently placed. A good landing builder may help you create clean, concise popunders. Affiliate networks are always more willing to feature code for a well-designed ad.

Second, think twice about offer selection. The more relevant it is, the greater the chance a user will engage with it. For example, on a file converter website, you could advertise proxies or anti-detect software. On a site with free movies, betting ads, gaming offers, or adult content offers perform well.

Best Usability Practices for Popunders

It’s not all about a clear offer and a neat layout. If your well-thought-out CTA doesn’t work, there’s no need to rush and change the pop ad. Success often comes from adapting the UI to the user’s device, location, and interests.

Campaign Setup for Different Devices

The majority of web traffic is mobile, so a responsive layout is essential. Pay attention to screen sizes. On a smartphone, keep the CTA front and center. It should appear instantly, without scrolling. Desktop popunders give you more freedom for bigger visuals and longer text above the fold.

Visuals and Ad Relevance

Our clients say that designing push creatives is often more challenging than setting up pop campaigns to achieve a high popunder conversion. 

The landing page simply needs to meet audience expectations. Key elements include a bold headline, concise copy, and a clear call-to-action.

Audience Segmentation and Targeting

To maximize the value of their offers, Kadam users choose our targeting options like mobile vendor, OS, browser, GEO, and language. Time-based segmentation also helps improve performance.

Popunder Profitability and Effectiveness of the Format

At Kadam, we have pop case studies that demonstrate high ROI and a steady stream of conversions from this format. As a publisher, you also benefit if your traffic converts well.

CPM and Popunder Conversion Rate

The average popunder CPM is $1. Tier 1 locations (the USA, Canada, and the UK) and Tier 2 countries $1,5. Tier 3 countries around $1.

Conversion rates (CR) can be impressive: up to 4% for nutra offers, 10% for finance and investing, and even higher if you use international traffic sources.

Ad Format Comparison by Profitability

Popunder competes with push and native ads, often winning on sheer volume. In verticals where website monetization depends more on the number of contacts than on deep user trust, this format delivers a better profit.

How to Measure Impact on Overall Monetization

Analyze not only direct clicks but also retention and repeat sessions. Monitor your eCPM over time, as it reflects the ad’s real effectiveness. To track these metrics, use Kadam’s built-in tracker, as well as analytics systems like Google Analytics.

FAQ

How do I know if my push and pop ads are irritating users?

Monitor key metrics like CR and CTR, Cost Per Lead, time on page, and bounce rate. If you see your CPL rising and lead volume dropping, your ads are becoming a nuisance.

How many times a day can I show a popunder without compromising usability?

We would say that 1–2 impressions per user per day is alright. Anything more than that is considered ineffective and drains the budget.

Can popunders be combined with other formats?

Yes. We highly recommend combining them with formats like push ads (including calendar push and in-page push), native ads, and banner ads, as they often complement each other.
