CASE STUDY · PAID ADS · USA
By Purple Circle, a performance marketing agency for D2C brands ·
The brief
The client sells bathroom products and projects to US homeowners, a high-consideration category where buyers compare many options before spending. They wanted predictable revenue from paid ads without a bloated budget. As a performance marketing agency, Purple Circle took a lean, ROAS-first approach.
What Purple Circle did
1. Brand-first positioning
Before launching ads, we applied a brand consultancy lens: who the buyer is, what makes the offer different, and which message earns trust in the US market. Clear positioning lifted click quality, which is what lowers cost per purchase.
2. Funnel-structured campaigns
We separated prospecting, mid-funnel and retargeting campaigns so every campaign had one job and one benchmark. That made winners and losers obvious within days.
3. Budget moved to winners
Budget shifted steadily toward high-ROAS campaigns and away from weak ones. The underperformer (3.00x) was kept small and the 5.64x campaign was capped while new creative was tested.
4. Small tests before scaling
New angles were validated at low spend first. One small test returned 15.86x on just $728, and was promoted only after it proved it could hold up with more budget.
Campaign results
| Campaign (by spend) | Spend | ROAS | Purchase value |
|---|---|---|---|
| Top scaler A | $20,890 | 10.72x | $224,021 |
| Top scaler B | $16,418 | 13.63x | $223,854 |
| Mid-funnel campaign | $9,317 | 6.73x | $62,727 |
| Low-return campaign | $3,241 | 5.64x | $18,281 |
| Underperformer | $1,754 | 3.00x | $5,257 |
| Small test | $728 | 15.86x | $11,548 |
ROAS by campaign (account average: 10.32x)
Small test 15.86x $728 spend
Top scaler B 13.63x $16,418 spend
Top scaler A 10.72x $20,890 spend
Mid-funnel 6.73x $9,317 spend
Low-return 5.64x $3,241 spend
Underperformer 3.0x $1,754 spend
Why it worked
- Concentration: The two top scalers took about 71% of total spend and delivered about 82% of purchase value.
- Fast pruning: Weak campaigns got small budgets, so they could not drag down the blended result.
- Test-then-scale: A high ROAS on small spend is a signal, not proof, so we scaled it in steps.
- Honest reporting: Spend, ROAS and purchase value were tracked together, never ROAS alone.

Conclusion
You do not need a huge budget to get strong returns from paid ads in the USA. You need clear positioning, structured campaigns, quick tests and the discipline to move money toward what works. This bathroom project shows that with about AUD 5K a month, a 5x average ROAS is realistic, and with the right scalers, the peak can go much higher. Results vary by offer, margin and market, so treat these numbers as a benchmark, not a promise.
Frequently asked questions
What is a good ROAS for a bathroom or home brand in the USA?
It depends on margin, but many brands target 3x to 5x as a healthy range. This project averaged 5x, with a peak of 10.32x.
What does a brand consultancy in the USA do for paid ads?
It defines positioning, audience and messaging before spend begins, so ads attract buyers who already understand the offer. That improves conversion and ROAS.
How do I choose the best social media agency in the USA?
Look for revenue-based reporting, proof at your budget level, clear campaign structure and transparency on spend. Ask for case studies with spend, ROAS and purchase value shown together.
