Affiliate Case Study: 113% ROI with NineCasino in Brazil

Case Study Overview

In early 2023, an affiliate team set out to identify a high-converting online casino offer for Brazil. They picked three live casino programs and ran identical Facebook campaigns over nine days. Their goal was simple: discover which offer would deliver the best return on ad spend in a notoriously competitive market.

Market Research & GEO Insights

Brazil’s 214 million population and passion for soccer make it a prime gambling destination. The team knew that visuals featuring national colors (yellow and green), local football stars, and Pix payment logos would resonate. Portuguese-language support and local VIP managers were non-negotiable when choosing any casino partner.

Split-Testing Three Offers

Using Facebook’s iOS-only targeting (ages 23–50, 75% men, 25% women), the team launched three campaigns: NineCasino, Brand 2, and Brand 3. They applied the same budget, creatives showcasing live gameplay reactions, and cloaking via Keitaro filters. After one day, performance looked like this:

• NineCasino: 1,194 clicks → 145 sales (CR 12.14%)
• Brand 2: 1,157 clicks → 75 sales (CR 6.48%)
• Brand 3: 1,105 clicks → 68 sales (CR 6.10%)

NineCasino’s conversion rate was nearly double its rivals, making it the clear winner for full-scale investment.

Optimizing the Winning Campaign

With NineCasino selected, the team refined ad creative by adding banners of popular banks and Pix icons. They duplicated top-performing ad sets, scaled budgets, and tightened look-alike audiences around depositors. Automatic account registration and mobile-friendly landing pages further boosted performance.

Results & Key Metrics

Over 24 days, the optimized campaign achieved:

• Total Spend: €48,900
• Total Revenue: €104,370
• Net Profit: €55,470
• ROI: 113%

NineCasino’s native Portuguese support, Pix payment integration, and solar-bright flag-colored design were key to strong user engagement and repeat play.

Conclusion

This experiment highlights the power of rapid split tests and localized creative in emerging markets. By running parallel campaigns and doubling down on the leader, the affiliate team turned a €48.9K budget into a €55.4K profit in under a month.
