Why publishers are re-evaluating ad formats right now
Publishers are scanning the Monetag Traffic Spike Calendar for 2026 to lock in the best-performing ad formats before seasonal demand peaks. The calendar highlights 60+ high-monetization events, giving publishers a clear signal to test and scale the right revenue streams. Popunder and push ads are two of the most scalable formats, but they serve different monetization goals and site types. Choosing the wrong one can leave revenue on the table during peak windows.
Popunder ads: fast setup, immediate revenue
Popunder ads open a new browser tab behind the current window, so they don’t interrupt the user’s flow. This makes them ideal for sites where user experience is a priority and where immediate revenue is the goal. Publishers report minimal setup time and quick integration with popunder networks, which is why they are often the first format tested when traffic spikes are expected. Popunders are less suitable for time-sensitive promotions because the ad doesn’t demand instant attention, but they can deliver consistent fill and CPMs during high-traffic events.
Push ads: higher long-term value, but more upfront work
Push ads deliver notifications directly to a user’s desktop or mobile device, creating a direct communication channel. This format requires more upfront work—such as crafting opt-in flows and managing subscriber lists—but it can generate higher long-term revenue and better user relationships. Publishers who invest in push see stronger lifetime value from engaged subscribers, especially when retargeting is layered in. Networks like Push.House report delivering 14 billion impressions daily across 180+ countries with 525 million active subscribers, showing the scale available to publishers who build push funnels.
How to decide before demand peaks arrive
Use the Monetag calendar to identify your next high-monetization window, then run a small test split between popunder and push ads. If your site prioritizes immediate revenue and minimal setup, popunders are the safer choice. If you can invest in opt-in flows and subscriber nurturing, push ads can deliver stronger lifetime value. For time-sensitive campaigns, avoid popunders and lean into push or in-page push formats, which perform better for urgent offers. Structuring campaigns around the funnel—using high-volume formats at the awareness stage and retargeting for conversions—helps agencies use traffic more efficiently during peak events.
What to watch during the next spike window
Monitor fill rates and CPMs in real time as traffic surges. Popunder networks typically provide stable fill during spikes, while push campaigns may see volatility if opt-in rates dip. If your push funnel is new, consider running a hybrid test: use popunders for immediate monetization and push for retargeting later in the funnel. This balances short-term gains with long-term subscriber value. Networks like PropellerAds and Monetag recommend structuring campaigns around the funnel to maximize efficiency during time-sensitive events.
