Give campaigns distinct jobs
Campaigns expanded from 39 to 145 with separate targeting roles, so budget could be allocated deliberately rather than averaged across the account.

Explore the results The Starting Point
An Established Business With an Underbuilt Growth Engine.
The brand operated 38 active SKUs on Amazon US, serving consumers and Amazon Business buyers through Seller Central. At handover, annual Amazon sales were approximately $12M, but advertising was limited to 39 campaigns and $2,982 in monthly spend. Shoppers often searched by active ingredient rather than brand.
The Work
One Plan. Connected Execution.
Replace dated content
The team produced 123 catalog and creative assets: 41 copy rewrites, 43 product-page images and 39 A+ modules. Production was tracked through to publication.
Measure against a usable baseline
Seller Central sales history supplied a 453-day baseline. Reporting compared revenue and units per day; pre-engagement session data was not available.

The Takeaway
Build the Structure Before Scaling the Budget.
Campaign roles, current product content and a reconciled baseline made the account easier to steer. The result is measured in revenue per day and units per day, alongside Advertising Efficiency, rather than spend alone.
Measurement Notes
The source describes a nine-month engagement beginning in November 2025 but does not specify the exact reporting end date. Daily revenue and unit changes are measured against a 453-day pre-engagement baseline. No pre-engagement session data was available, so no before-and-after conversion uplift is claimed. ROAS, ACoS, TACoS and new-to-brand sales are reported snapshot metrics; ad-attributed sales are not the same as incremental sales.
