Hey fellow affiliates!


Here’s something we know all too well — testing new campaign bundles is costly, time-consuming, and often full of false starts. But what if you could skip the heavy lifting and plug directly into a working combo that’s already been optimized and tested?


Our media buying team recently did just that — combining CPL survey offers and SOI sweepstakes from our internal Zeydoo suite with high-quality Popunder traffic from Galaksion — and we managed to pull in a clean profit of $665 in just 30 days. Not bad for a fairly “set-it-and-watch-it” campaign. Let’s break it all down.


The Winning Formula: CPL + SOI + Popunder​


We ran a bundle of three offers:


  • Sweep Survey (Android)
  • Captcha Survey
  • Samsung A53 Rewardis Sweepstakes

The idea was simple: leverage CPL (Cost Per Lead) and SOI (Single Opt-In) mechanics for faster conversions, matched with global Popunder traffic targeted exclusively on Android devices.


The beauty of this approach? The flow is light, the barrier to entry is low for users, and we had full control over traffic zones, creatives, and optimization.


Campaign Performance (10/02 – 10/03)​


  • Traffic Source: Galaksion
  • Ad Format: Popunder
  • Targeting: Mobile Android, OS version 8+
  • GEO: Worldwide
  • Spend: $1,618
  • Revenue: $2,284
  • Profit: $665
  • ROI: 41%

GEOs and Targeting Strategy​


We started with a wide WorldWide (WW) campaign, but closely monitored performance by GEO and zone. GEOs like Nigeria (NG) and South Africa (ZA) turned out to be our best performers for the Rewardis offer. Other high-ROI markets included Indonesia (ID) and Brazil (BR) — especially for surveys and sweepstakes targeting Android users.


Zones that delivered consistently poor ROI were promptly blacklisted. We didn’t just stop traffic entirely from those GEOs — we retained specific profitable sub-zones and re-optimized accordingly. This micro-optimization helped squeeze even more out of what appeared to be weak spots at first glance.


Landing Pages & Creatives​


Landing pages were built with conversion in mind:


  • Timers to instill urgency
  • Localized content with user location, date, and limited spots
  • Simple gender selectors and questions to kickstart interaction
  • Visual appeal through clear prize images (like the Samsung A53)

The idea was to hook the user visually, build trust with location relevance and structured flow, and minimize friction at each step.


One major advantage of the Rewardis flow is that it doesn’t just rely on a single contest. Once the user registers, they enter an ecosystem of ongoing offers and contests — which improves retention and overall engagement.

Optimization Notes​


  1. Start Low, Scale Smart: We began bidding at minimum rates to test waters, then scaled up CPM once we identified top-performing zones.
  2. Blacklist Management: Negative ROI zones were blacklisted immediately, with exception handling for profitable sub-segments.
  3. Creative Rotation: Multiple creatives were tested (up to 10 per campaign), and winners were isolated for scaling.
  4. Offer Adjustment: When the Samsung A53 campaign hit its limit, we smoothly transitioned to A55 creatives to stay current and relevant.

Key Takeaways​


  • CPL surveys + SOI sweeps are a perfect combo for Popunder traffic, especially on Android WW.
  • Reward-based flows keep engagement going beyond the first conversion. This boosts your overall return from the same user pool.
  • African and LATAM GEOs perform well, particularly for sweepstakes and survey flows.
  • Zone-level optimization is everything — even GEOs with lower performance averages can contain golden sub-zones.

Final Thoughts​


This case proved to us again how important it is to test efficient bundles, track performance closely, and not underestimate the power of Popunder traffic when aligned with the right offers.


Whether you're just starting out or looking to scale low-maintenance campaigns, this approach gives you a solid framework to work with. The ROI was steady, the effort minimal once setup was complete, and the learnings invaluable.
