The challenge

Monthly revenue had plateaued at roughly $150K. The account needed a coordinated improvement in how shoppers found the products and how the listings converted that traffic. Increasing advertising spend alone would not address both problems.

Our approach

  • Reviewed listing quality, campaign structure, and competitive positioning to identify priorities.
  • Reworked listing copy and search terms, alongside A+ content and the brand storefront.
  • Restructured campaigns across Sponsored Products, Sponsored Brands, and Sponsored Display.
  • Reviewed creative and campaign performance together to guide ongoing optimization.

What changed

Over six months, reported monthly revenue increased from approximately $150K to $281K, a rounded increase of 87%. ACoS fell from 32% to 16%, while TACoS fell from 22% to 13%. The reported conversion-rate improvement was 51% relative to the starting rate, not a 51-percentage-point increase.

What this engagement shows

Listing quality and advertising efficiency improved together. The reported results show higher revenue alongside a lower advertising cost ratio; they do not establish net profit.

Recreated chart from agency-reported results. Not a Seller Central screenshot. Only starting and ending values are shown; no monthly trend is implied. Sales are indexed because absolute amounts are not supplied; a 142% increase takes the index from 100 to 242. Source reports are not included in this preview. Individual results vary.

The challenge

The brand wanted to scale advertising, but an ACoS of 41% made the cost of that growth a concern. The engagement focused on campaign structure, search-term coverage, and spend allocation.

Our approach

  • Separated branded, generic, and competitor targeting to make performance easier to evaluate.
  • Used search-term reports to expand keyword coverage and refine negative keywords.
  • Expanded the campaign mix with Sponsored Brands and Sponsored Display.
  • Combined bid management with regular human review to keep decisions tied to account performance.

What changed

Across the four-month engagement, reported ad-attributed sales increased by 142%, while ACoS declined from 41% to 19%. These are separate measures: the sales figure describes growth in ad-attributed revenue, while ACoS describes ad spend as a share of that revenue.

What this engagement shows

More efficient advertising can create room to scale. ACoS alone is not a measure of profitability, so the result should be considered alongside product margins and total account performance.
