Why publishers are rethinking ad formats before the next spike

Publishers with seasonal traffic windows are already checking Monetag’s Interactive Traffic Spike Calendar 2026 to lock in the best ad format before demand peaks. The calendar lists 60+ high-monetization events, giving publishers a clear view of when CPMs and fill rates typically rise. Choosing the right format now—popunder or push—can mean the difference between a flat revenue curve and a sharp seasonal lift.

Popunder ads: fast revenue with minimal setup

Popunder ads open in a new tab behind the current page, so they don’t interrupt the user’s experience. Publishers can start monetizing traffic almost immediately because the format requires little configuration and no user consent beyond standard ad network terms. According to Monetag’s guide, popunders are recommended when you need immediate revenue with minimal upfront work, especially on sites where users arrive once and leave quickly.

Because popunders don’t rely on persistent user opt-ins, they can fill and monetize traffic from any source, including paid social and search campaigns. Publishers running seasonal promotions or flash traffic spikes often see quick payouts from popunder placements, making them a practical choice for short-term monetization windows.

Push ads: higher lifetime value, but you must earn consent

Push ads require publishers to request permission to send browser notifications, which means building a consent-based audience over time. The upfront effort pays off in higher long-term revenue and better user relationships, according to Monetag’s comparison. Once a user opts in, push notifications can re-engage visitors repeatedly, increasing page views and session depth beyond the initial visit.

For publishers with recurring audiences—such as blogs, newsletters, or membership sites—push ads can turn one-time visitors into repeat users, lifting overall monetization. The format is less suited to one-off traffic spikes because it depends on sustained opt-in rates, but it delivers stronger lifetime value when the audience is engaged.

Which format to prioritize before the next spike

Use the traffic spike calendar to decide which format to lock in. If your site relies on flash traffic or paid campaigns, prioritize popunder ads for immediate monetization. If your audience is returning visitors or you can invest in building consent lists, push ads can deliver higher lifetime revenue and better user relationships.

Many publishers hedge their bets by running both formats simultaneously. Popunders capture revenue from new visitors, while push ads nurture returning users for long-term growth. The key is to test placements and opt-in flows before the calendar’s high-monetization windows arrive, ensuring your stack is ready when CPMs and fill rates peak.

Quick setup checklist before the spike

  • Verify your ad network supports both popunder and push formats.
  • Test popunder placements on high-traffic pages to confirm they don’t hurt user experience.
  • Run a small push notification campaign to gauge opt-in rates and segment your audience.
  • Check Monetag’s calendar for the next seasonal surge and align your format choice with the expected traffic type.

By locking in your format choice now, you’ll avoid last-minute scrambling when the next traffic spike hits.

Bottom line

Popunder ads are the go-to for immediate revenue with minimal setup, while push ads build long-term value through consent-based engagement. Use Monetag’s traffic spike calendar to decide which format to prioritize before the next seasonal surge, and test both placements to maximize revenue when demand peaks.
