This case study breaks down how we profitably ran SOI dating offers from AdsEmpire using native ads in Germany. Over a 16-day period (01/06/2022–21/06/2022), we spent $1,486 and earned $1,953.50 in profit, achieving a 31% ROI. We focused on mainstream SOI offers paying $4–$5 per lead and tracked everything ourselves rather than relying on Smartlinks. Native mobile traffic drove about 95% of volume and revenue. TrafficStars proved the most effective source with separate mobile and desktop campaigns, German language targeting, and proxy exclusions. We bought on CPM viewable, bidding $0.01 for mobile and $0.005 for desktop, guided by Recommended bids. Creatives featuring mature women (40+) and localized, curiosity-driven headlines performed best; simple CTAs boosted clicks. We capped frequency at 3/day, used {city} macros, refreshed creatives weekly, and prioritized registrations over CTR. Auto-rules whitelisted top sources and blacklisted underperformers. When traffic/conversions dipped in week three, we paused to preserve ROI.
