[Case Study] 637K Conversions: How a SEA iGaming Campaign Scaled with Low CPA
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.
Instead of pushing a single well-known product, the team worked with several lesser-known iGaming brands. This approach provided greater flexibility in testing and allowed them to maintain a steady flow of traffic without depending on a single offer.
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
The campaign started with relatively low bids to collect data and understand traffic behavior. Once patterns became clear, the team gradually increased bids only on segments that proved their value.
Instead of trying to optimize everything at once, they focused on what actually mattered: keeping CPA within KPI while improving post-install performance.
Traffic quality was refined through whitelist strategies and close collaboration with managers, while install costs were pushed down to around $0.25. At the same time, the team didn’t stop at installs…They continuously tracked user behavior, especially in relation to FTDs (first-time deposits).
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.
What This Case Actually Shows (& Why It Matters for World Cup Traffic)
What makes this campaign peculiar isn’t just the numbers (although 637K conversions definitely don’t hurt!). What really matters is how those results were achieved.
Interestingly enough, the logic behind this setup is very similar to what we expect to work during the World Cup traffic rush.
As already mentioned before, success during major events isn’t achieved only when you react faster than everyone else. It comes when you prepare early and build campaigns that can handle traffic waves without losing efficiency.
Another advantage of this approach is that it allows campaigns to scale more sustainably over time. As previously registered users continue converting into first-time deposits (FTDs), the effective cost per deposit gradually decreases – making it easier to increase baseline install rates later without hurting overall performance.
It also proves another important point: Tier-1 markets aren’t always the best opportunity. Southeast Asia delivered a strong mix of lower competition, cheaper traffic, and highly engaged users (while many advertisers were busy fighting over the same expensive auctions elsewhere).
Most importantly, this case shows how important the funnel itself was for scaling. Instead of sending users directly to the product, the team used a gamified pre-landing and a smooth PWA flow to warm users up before installation.
This helped reduce friction, improve install quality, and scale traffic more efficiently.
And finally, this case is a good reminder that simple funnels still work. Even with all the hype around new traffic sources and AI-driven setups, a clean flow, good timing, and solid optimization can still scale extremely well when executed properly.
