Case Studies

Rio Roo Consulting has managed Amazon advertising and account operations for brands in nine countries since 2018, across consumer packaged goods, skincare, furniture, pet supplements, travel goods, and education. The five case studies below document specific engagements: the problem the brand faced, the strategy we built, and the measured outcome. Each links to a full write-up with detailed metrics.

From Chaos to Control

A premium consumer packaged goods brand was losing margin to barcode errors that triggered fulfillment fees on every unit, while subscription uptake stayed low despite strong repeat purchasing. We resolved the backend labeling and inventory problems, introduced trial sizes as an acquisition entry point, built a tiered subscription model with graduated discounts, and rebuilt advertising funnels around customer lifetime value. Subscriptions grew 380% over three years, off-season monthly sales rose 276%, peak season sales increased sixfold, and TACoS fell from 18% to 9%.

Repricing the Narrative

A premium travel brand was spending $18,000 to $22,000 monthly on advertising while relying on constant coupons and seasonal discounts to justify price points nearly double those of competitors. We eliminated the money-losing promotions after data showed minimal conversion impact, raised prices by $4 per unit, reinforced premium positioning through quality messaging and social proof from over 10,000 reviews, and added cross-platform campaigns using PixelMe and Amazon DSP. Net profit grew 53% year over year, with TACoS at 17 to 19% against a category benchmark of 20 to 25%.

The 89X Leap

A skincare brand had plateaued at low four-figure monthly revenue, held back by inefficient PPC structures in a category where clicks routinely cost $2.50 to $4.00. We worked in phases: restructuring campaigns and building A+ Content first, then integrating professional video into listings and advertising, then developing a subscription model and layering in Sponsored Display, DSP remarketing, and competitor placement targeting. Ad efficiency significantly outperformed category benchmarks. When a global agency later took over the brand’s marketing, the client retained Rio Roo with exclusive Amazon decision-making authority.

From Splintered Sales to a Solid Foundation

A reclaimed-wood furniture brand faced declining sales, a conversion rate below 1%, acquisition costs above $50, and a 9 to 12% return rate. We rebuilt the account around a multi-tiered campaign structure with extensive negative keywording and N-gram analysis, restructured variation families for discovery, and repositioned lower-priced items as entry pieces funneling buyers toward premium products. The sales decline reversed within one month. Profit increased 400%, ACoS reached 24% against a 30 to 35% category average, and higher-margin variation sales grew 13.5% year over year.

From Underdog to Alpha

A premium pet supplement brand was spending $8,500 monthly on advertising at a 91% average ACoS, occasionally reaching 134%, with flat sales and poor repeat purchase rates. Over 60 days we expanded Sponsored Brands Video based on proven performers, consolidated single-target ad sets to speed learning, separated branded from unbranded spend, added defensive campaigns, restructured variation trees, and introduced Subscribe and Save coupons priced at the equivalent of one to two ad clicks. Ad sales doubled from $13.8K to $28.2K, ACoS fell 42%, subscriber count doubled, and net profit rose 40%.
