PopUnder traffic remains one of the most effective ad formats for iGaming campaigns, especially during major sporting events. However, achieving sustainable profitability often depends on continuous optimization rather than simply increasing traffic volumes.

In this case study, we analyzed a FIFA World Cup campaign targeting Brazil and demonstrated how several optimization techniques significantly improved overall performance.

Campaign Overview

  • Vertical: iGaming 
  • GEO: Brazil
  • Event: FIFA World Cup Campaign

Initial Performance

The campaign initially ran with standard PopUnder settings and generated stable results, but there was still room for improvement.

  • Spend: $6,000
  • Revenue: $7,500
  • ROI: 25%

Optimization Strategy

To enhance campaign efficiency, we implemented three key changes:

First, we applied strict source filtering and blacklisted domains with consistently low conversion rates. This allowed us to focus the budget on higher-quality traffic sources.

Second, we introduced pre-landers designed specifically for football fans. These pages helped warm up users before reaching the main offer, increasing engagement and improving conversion rates.

Finally, bid caps were optimized based on device type, enabling more precise budget allocation and better control over acquisition costs.

Results

After implementing these optimizations, campaign performance improved considerably.

  • Spend: $7,200
  • Revenue: $11,520
  • ROI: 60%

Overall revenue increased by 53.6%, while ROI grew from 25% to 60%.

Key Takeaway

This case clearly demonstrates that granular source-based bidding, combined with traffic quality control and audience-tailored pre-landers, can dramatically improve campaign profitability. Even with a higher acquisition volume, a data-driven optimization strategy can successfully offset costs and maximize returns.
