Case Study 1 — PPC Scale & Profitability

CLIENT

Established consumer brand in the health & wellness category

CHALLENGE

The client was running Amazon ads in-house with limited structure. Campaigns were generating sales but ACOS was high and the true cost of advertising — factored against fulfillment fees and returns — was eroding margins significantly. They had no visibility into actual profitability per unit.

WHAT WE DID

We conducted a full profitability analysis to establish accurate break-even targets, then restructured the ad account from the ground up — building tightly themed campaigns, implementing aggressive negative keyword harvesting, and shifting budget toward their highest-margin ASINs. We also used search term data from the ad campaigns to improve organic ranking through listing updates.

RESULT

Year-over-year sales increased by over 200% within the first year of management. ACOS dropped to a level that aligned with the client’s margin targets, and the client now has a clear, ongoing picture of their true Amazon profitability.

This engagement is part of the nearly $2.5M in Amazon PPC spend Graywall Marketing has managed across our client portfolio.

Case Study 2 — Inventory & Logistics Turnaround

CLIENT

Outdoor & garden brand with an established Amazon presence

CHALLENGE

Frequent stockouts were costing the brand sales and organic ranking. Poor demand forecasting meant they were either overstocked on slow movers or running dry on their bestsellers at peak moments. The client’s team was spending significant time managing logistics reactively rather than proactively.

WHAT WE DID

We implemented a demand planning and forecasting process tied to their sales velocity, seasonality patterns, and Amazon lead times. We also audited their FBA shipment strategy and LTL freight setup to reduce per-unit shipping costs and improve inventory flow into Amazon’s fulfillment network.

RESULT

The client went from multiple stockouts per quarter to zero stockouts over the following year. Revenue nearly doubled, and their internal team reclaimed significant bandwidth by handing off Amazon operations entirely to Graywall Marketing.

Case Study 3 — Full-Service Amazon Launch

CLIENT

Pharmaceutical company expanding a supplement line onto Amazon

CHALLENGE

The brand had strong credibility and an established customer base outside of Amazon, but no Amazon presence. They needed to launch correctly — with optimized listings, a compliant brand presence, and advertising that could build momentum without burning budget during the ramp-up period.

WHAT WE DID

We managed the end-to-end launch — handling Brand Registry enrollment, building their Amazon Storefront, writing and optimizing all product detail pages, enrolling eligible products in Vine for early review generation, and building a structured launch PPC strategy designed to build organic ranking while keeping ad spend efficient.

RESULT

The supplement line launched and grew steadily from day one. The Amazon channel now operates independently of the client’s internal team with regular performance updates and payments on schedule. The client described the result as running “like a well-oiled machine.”
