Established Maternity & Motherhood Apparel Brand · Anonymous Client Case Study
Scaling Amazon PPC without sacrificing efficiency.
How an established maternity and motherhood apparel brand nearly doubled total sales while improving advertising yield.
The client and the challenge
The brand had meaningful awareness and a proven product assortment, but its advertising program was not producing enough scalable, efficient growth. AMZ PHD assumed PPC management in September 2025.
- Scale was constrained. The existing program generated revenue but lacked the yield needed to support aggressive growth.
- Efficiency had to hold. Increasing spend alone was not enough; incremental dollars needed to produce stronger returns.
- The full catalog needed support. A varied apparel assortment required disciplined prioritization across products, search terms, seasonality, and inventory availability.
- Success had to show up in total sales. The goal was profitable brand growth, not an isolated improvement in advertising metrics.
The management approach
The program centered on building a repeatable system for efficient scale. The account was managed continuously at the campaign, targeting, and product level, with budget moving toward opportunities demonstrating the strongest combination of conversion, relevance, and growth potential.
- Account structure and control. Campaigns were organized to provide clearer visibility into product and targeting performance, enabling more precise bid and budget decisions.
- Search-term development. Converting customer searches were identified, promoted into controlled targeting, and protected with negatives where appropriate.
- Product-level prioritization. Investment was aligned with products capable of supporting traffic, conversion, and in-stock demand rather than spread evenly across the catalog.
- Active bid and budget management. Spend was scaled where returns justified it and reduced where traffic failed to convert efficiently.
- Whole-business measurement. ACOS and ROAS were evaluated alongside total sales, units, sessions, and TACOS to prevent optimization toward a single metric at the expense of growth.
Twelve-month results
| Metric | Prior 12 months | First 12 managed | Change | What it shows |
|---|---|---|---|---|
| PPC spend | $105,330 | $261,879 | +149% | Investment scaled materially |
| PPC-attributed sales | $388,876 | $1,079,727 | +178% | Sales outpaced spend growth |
| PPC ROAS | 3.69x | 4.12x | +12% | More ad sales per dollar |
| ACOS | 27.1% | 24.3% | −10% | Efficiency improved at scale |
| Total Amazon sales | $913,512 | $1,757,085 | +92% | Growth reached the full business |
| Units ordered | 30,248 | 51,013 | +69% | Substantial demand expansion |
| Sessions | 434,304 | 648,296 | +49% | Broader qualified traffic base |
TACOS increased from 11.5% to 14.9% as the brand deliberately invested at a much larger scale. That investment produced 92% total-sales growth and 69% unit growth, while PPC-level ACOS still improved. This was the documented tradeoff during an intentional market-expansion phase.
The strongest proof point: August year over year
By August 2026—the twelfth month under management—the program had reached a substantially larger operating level while delivering its strongest efficiency evidence.
| Metric | August 2025 | Managed August 2026 | Change |
|---|---|---|---|
| PPC-attributed sales | $31,263 | $112,619 | +260% |
| Total Amazon sales | $71,382 | $183,579 | +157% |
| PPC spend | $8,882 | $26,332 | +196% |
| ACOS | 28.4% | 23.4% | −5.0 points |
| PPC ROAS | 3.52x | 4.28x | +22% |
| Units ordered | 2,256 | 5,384 | +139% |
| Sessions | 31,939 | 69,301 | +117% |
Why this result matters
- Many PPC programs can improve efficiency by cutting spend, or grow attributed sales by accepting weaker returns. This case did both difficult things at once: it scaled investment dramatically and improved the revenue yield of each advertising dollar.
- PPC sales grew faster than spend, ACOS declined, ROAS rose, and total Amazon sales nearly doubled.
The takeaway
Disciplined Amazon PPC management can be a growth engine—not merely a cost center—when campaign decisions are tied to product economics, conversion behavior, and total-business outcomes.
