Why publishers should decide now before seasonal demand peaks

Publishers preparing for seasonal traffic surges in late 2026 need to choose ad formats that balance immediate revenue with user experience. Popunder ads and push ads monetize different user behaviors, and the choice affects both short-term earnings and long-term audience retention. The Monetag traffic spike calendar highlights 60+ high-monetization events in 2026, signaling windows where ad performance and user tolerance for interruptions shift. Publishers who test and optimize formats now can capture higher revenue during peak periods without alienating their audience.

Popunder ads: fast setup, immediate revenue, but higher user friction

Popunder ads open in a new browser tab behind the current page, generating revenue when users eventually close the tab. They require minimal technical setup and can deliver immediate earnings, making them attractive for publishers with low-traffic sites or urgent monetization needs. However, popunders interrupt the user experience by opening hidden tabs, which can increase bounce rates and damage site reputation if overused. According to Monetag’s internal analysis, popunders are less suitable for time-sensitive promotions because the ad does not demand instant attention, reducing conversion rates for urgent offers.

Publishers should limit popunder frequency and pair them with high-CPM verticals such as iGaming, where users are already primed for engagement. The iGaming traffic comparison from Business of Apps underscores that certain ad formats perform better in specific verticals, and popunders align with gaming audiences that tolerate interruptions for rewards.

Push ads: higher long-term revenue with upfront relationship building

Push ads deliver notifications directly to users’ devices, creating a direct communication channel that can drive repeat visits and higher lifetime value. They require more upfront work—such as crafting compelling opt-in messaging and segmenting audiences—but can generate higher long-term revenue and better user relationships. Push ads are ideal for publishers with engaged audiences who value timely updates, such as news sites or deal aggregators. The recommendation from Monetag’s internal guidance is to prioritize push ads for sites where user retention and repeat traffic are critical to monetization.

Push ads also allow for precise targeting and retargeting, which improves conversion rates for offers that benefit from urgency, such as flash sales or limited-time promotions. Networks like Push.House, which started as a push specialist before expanding into popunders, deliver 14 billion impressions daily across 180+ countries, indicating strong demand for push traffic among advertisers.

How to test and decide which format to prioritize

Publishers should run A/B tests on a subset of traffic to compare popunder and push ad performance before committing to one format. Start with a small percentage of visitors to measure impact on bounce rates, session duration, and revenue per thousand impressions (RPM). Use the Monetag traffic spike calendar to align tests with upcoming seasonal peaks, such as holiday shopping windows or major sporting events, when user tolerance for interruptions may be higher.

For sites with low-traffic or new audiences, popunders can provide a quick revenue boost while building audience size. For established sites with loyal users, push ads are more sustainable and can improve long-term monetization. Consider vertical alignment: dating offers, for example, convert better with video ads that build emotion, while push and popunder ads excel in verticals where urgency or rewards drive action.

When to switch formats during peak demand

During high-traffic events, publishers can temporarily increase popunder frequency to capture immediate revenue, then shift to push ads for post-event engagement and retargeting. This hybrid approach balances short-term gains with long-term audience health. Monitor network performance metrics such as click-through rates and conversion rates to adjust strategies in real time. The key is to avoid overloading users with interruptions, which can lead to ad fatigue and lower overall earnings.

By aligning format choices with seasonal demand and audience behavior, publishers can maximize revenue without sacrificing user experience. The Monetag traffic spike calendar provides the planning signal, while push and popunder ads offer the tactical flexibility to adapt to changing conditions.

Use the calendar to identify your next high-monetization window, then test formats now to ensure your stack is ready when demand peaks arrive.

Quick decision guide for publishers

  • Choose popunders if: You need immediate revenue, have low-traffic sites, or target verticals like iGaming where users tolerate interruptions.
  • Choose push ads if: You prioritize long-term revenue, have engaged audiences, or run time-sensitive offers that benefit from direct communication.
  • Test both if: You have sufficient traffic to segment audiences and measure impact on user experience and revenue.

Align your choice with the Monetag traffic spike calendar to ensure your monetization strategy is optimized for the next seasonal peak.
