Case Study: Scaling a Cosmetics SOI Voucher Campaign to $18K Profit in Two Months

Coming up with fresh angles for ad creatives in a niche that has been around for decades is the kind of challenge that can sell a spy tool subscription to even the most imaginative affiliates. Cosmetics vouchers is a good example of well-tread territory where lifting creatives wholesale can easily look like the only sensible option. What happens when you stop running scouted ads as-is and start iterating on your own? Apparently, a $18,000 profit in two months.

Phase 1: Early Failures in Germany

The team’s journey began in July 2024 with a popular SOI vouchers offer from a well-known cosmetics brand. Following the standard playbook, they launched campaigns in Germany with creatives pulled from spy tools.

Angles tested:

– “Get this makeup set for free”
– “Are you 36? Get a set of “brand name cosmetics””
– “Free samples from our latest collection”

Results (Germany, July 10–15, 2024):

Spend: $50
Revenue: $5–9
ROI: Deeply negative

The campaigns flopped. Low engagement and poor conversions made it clear: spy-tool creatives and generic “freebie” angles weren’t working.

Phase 2: Breakthrough in the Netherlands

The turning point came when the affiliate stumbled upon a fresh angle in the Meta Ads Library: cosmetics testers.

Instead of giving away free products, the campaign was reframed as the brand “looking for testers of new cosmetics.” This angle resonated, and a new landing page was built around it.

Results (Netherlands, Oct–Dec 2024):

ROI: 15–20% sustained for three months
Traffic volume: 50–100 leads/day

By emphasizing exclusivity and participation (rather than freebies), conversions improved significantly.

Phase 3: Optimization & Seasonal Tailwinds

In January 2025, the team lead stepped in to refine the campaign:

– Swapped small travel sets for large premium sets in creatives
– Highlighted the need to “fill out the questionnaire,” which boosted CR
– Improved messaging consistency across three landing pages

This pushed ROI up to 30% in the Netherlands.

At the same time, seasonality worked in their favor. In January and February, Facebook CPCs drop post-holidays, making traffic cheaper. With the same funnel, ROI jumped to 50–60%.

Phase 4: Scaling to Spain & Portugal

Feeling confident, the team expanded into Portugal and Spain on January 25, 2025. The results were explosive:

Spain (Feb–Mar 2025):

Spend: $32,000
Revenue: $46,000
Profit: $14,000

Portugal (Feb–Mar 2025):
Spend: $10,000
Revenue: $14,000
Profit: $4,000

Combined two-month results:

Total Spend: $43,065
Total Revenue: $61,277
Total Profit: $18,212

Lead caps were raised to 800 daily leads in Portugal and 1,000 daily in Spain, sustaining strong volume and profitability.

Lessons Learned

Originality beats spy tools — borrowed creatives had poor conversions. Custom-made creatives and unique landing pages drove success.

Angles matter — positioning the offer as a “tester opportunity” created trust and engagement.

Timing can boost ROI — January/February’s cheap CPCs gave campaigns a major edge.

Use engagement as feedback — positive comments = fresh angle. Negative comments = fatigue.

Iterate relentlessly — unprofitable testing in Germany eventually led to breakthrough success elsewhere.

Conclusion

What started as a failing campaign in Germany became a multi-geo success that generated $18,000 profit in just two months. Going from $5 revenue on a $50 spend to over 40% ROI in a five-figure campaign is only possible if you don’t abandon the idea and keep testing.

For affiliates looking to replicate this success, the lesson is clear: stop relying on spy tools, test your own unique angles, and take advantage of seasonal shifts in traffic. And register in ClickDealer of course.
