The Background

Scaling a Competitive Consumer Product on Amazon

The product operates in a highly competitive Amazon category where multiple sellers compete on price, placement, and conversion efficiency. Paid media is the primary growth lever, but scaling spend without discipline quickly erodes margin.

At the start of October, the product was generating consistent sales but profitability was constrained. Advertising spend was necessary for visibility, yet efficiency metrics left limited room for aggressive scaling.

The objective of the engagement was to increase revenue and profit simultaneously—without relying on disproportionate ad spend increases.

The Challenge

Growth Without Margin Loss

Initial performance analysis highlighted several constraints:

  • !Revenue growth was tightly linked to ad spend increases.
  • !Efficiency metrics (ACOS and TACOS) limited safe scaling.
  • !Conversion stability needed to be maintained during increased traffic.
  • !Spend needed tighter control to avoid inefficient visibility.

The challenge was not generating demand, but scaling profitably under competitive pressure.

The Solution

Efficiency-First PPC Execution

A structured optimisation approach was implemented with a focus on control, intent, and conversion support.

Campaigns were restructured around intent-based segmentation, with ongoing search-term refinement, negative keyword expansion, and budget reallocation toward proven performers. Placement exposure was actively managed to avoid inefficient visibility, while listing-level adjustments were made to support conversion stability during scale.

We run Amazon accounts too. See our Amazon PPC service.

All optimisation decisions were guided by performance data from Amazon Ads and Seller Central reporting.

  • Net profit increased by 310.7%
  • Ad-attributed sales increased by 58.6%
  • TACOS reduced from 20.41% to 13.48%
  • ACOS improved while spend increased modestly

Year-over-Year Performance Expansion (Oct–Dec)

Beyond month-over-month scaling, the account demonstrated exceptional year-over-year growth when comparing the same October–December period against the previous year.

Year-over-Year Growth Highlights (Oct–Dec)

  • Revenue increased by approximately 401% year over year
  • Units sold increased by approximately 419% year over year

06 · What we did

Our Role

Performance Control at Scale

The engagement focused on PPC optimisation, spend efficiency management, and listing-level support during scale. Performance improvements were validated through Amazon Ads reporting and Seller Central business data.

Key Takeaway

On Amazon, sustainable scale comes from efficiency and control, not higher ad spend.

Data Verification

All metrics and outcomes were verified using the Amazon Ads Console and Amazon Seller Central Business Reports for the period from October 1 to December 31.

TACOS was calculated as Advertising Cost ÷ Total Sales using Seller Central revenue and ad cost data.

No projections or estimates were included.
