The PropellerAds team shared a new case study showing how a Southeast Asia iGaming campaign scaled to 637K conversions and 720K installs while maintaining low CPA and meeting strict KPI targets.

According to the case, the campaign focused on a simple but scalable approach: prioritize volume first, then optimize performance around efficiency. During Q1 2026, the setup generated 1.89B impressions, 637K conversions, and $222K in revenue.

The SetUp

Vertical - iGaming

Formats - Popunder, IPP (In-Page Push), Interactive Ads

Buying model - CPA with KPI on cost per deposit

Period - 1 January 2026 – 31 March 2026

Target region - Southeast Asia

Instead of relying on one large offer, the team rotated multiple lesser-known iGaming brands simultaneously to keep traffic stable, reduce creative fatigue, and improve testing flexibility.

The Strategy

The campaign strategy was built around a straightforward approach: scale traffic volume first, then optimize performance based on real data and user behavior.

One of the key elements was multi-brand rotation. Instead of concentrating traffic on a single “winning” offer, the team simultaneously rotated several iGaming brands.

The funnel structure itself also played a major role in scaling. Rather than directing users straight to the product, traffic first passed through a gamified pre-landing page before moving into a PWA (Progressive Web App) flow.

The overall user journey remained intentionally simple: web focused traffic. Users moved from the prelander to the PWA install flow and then directly into the product itself without unnecessary steps that could reduce conversion rates at scale.

Optimization

On the optimization side, the campaign launched with lower bids to collect traffic data and better understand user behavior. Once high-performing segments became clear, bids were gradually increased only on traffic sources that consistently delivered value within KPI targets.

The team also focused heavily on whitelist optimization, traffic quality refinement, and post-install performance, particularly FTD activity. As a result, install costs were reduced to around $0.25 CPI while maintaining stable scalability across the campaign.

Results

As a result, the campaign achieved full KPI compliance with:

720K installs

637K conversions

$222K revenue

$0.25 CPI

The case study also highlighted several key takeaways for large-scale event traffic, including early campaign preparation, long-term FTD optimization, SEA traffic potential, and the continued effectiveness of simple funnels combined with strong optimization.
