[Case Study] 637K Conversions: How a SEA iGaming Campaign Scaled with Low CPA

[PropellerAds]

What does it take to scale a Southeast Asia campaign without blowing up CPA? This case breaks down how a simple funnel and smart optimization led to 637K conversions and $222K in revenue.

The first quarter (Q1) of 2026 turned into a strong scaling window for a Southeast Asia iGaming campaign that focused on one simple idea: volume first, efficiency second.

Instead of chasing quick wins, the team built a system that could absorb large volumes of traffic while staying within strict CPA limits (and it paid off).

Over the quarter, the campaign reached considerable heights:

Setup​

The setup was intentionally kept simple so that there was no over-engineering nor unnecessary complexity.

Strategy​

The strategy followed a very practical logic: build volume fast, then shape performance around it.

Multi-brand rotation:
Rather than betting on one “perfect” offer, the team rotated multiple brands at the same time. This made testing faster, reduced risk, and helped keep traffic stable even when individual creatives or funnels started to fatigue.

Pre-landing + PWA (Progressive Web App) flow:
At the same time, the funnel itself did most of the heavy lifting. Instead of sending users directly to the product, the traffic first went through a gamified pre-landing. This strategy allowed users to warm up and made the transition to installation feel like a natural next step.

Web-focused traffic:
From there on, users first moved from prelander to PWA install and then into the product itself. This user journey included no unnecessary steps, but a smooth path designed to convert at scale.

Optimization​

Instead of trying to optimize everything at once, they focused on what actually mattered: keeping CPA within KPI while improving post-install performance.

Results​

The campaign achieved full KPI compliance and strong scalability:

By the end of the period, the campaign wasn’t just profitable but was stable and scalable. Most importantly, it fully met the advertiser’s KPI and proved strong enough to be scaled further into new regions.

Volume first, efficiency second only works if you have the budget to burn. Most small affiliates do not. This case is for teams with deep pockets and a patient advertiser.

Then get better at this so you can compete. Their budget was for Q1, 3 months. That was only $2k a day. That is not a huge budget, it is for an average affiliate with a stable and predictable business model. Super affiliates might spend $20k a day and much more.

Very reasonable and very well presented. It can be done with a smaller budget also. Try a $1k a day. Try $500 a day.
