Case Study: a UK-based home appliances brand cuts ACOS by 55% and scales sales with Quartile

UK-based Home Appliances Brand cuts ACOS by 55% with Quartile

A UK-based home appliances brand with a catalog of over 3,000 SKUs faced a significant scaling challenge on Amazon. Whenever it attempted to increase its advertising spend, its performance declined, causing its ACOS to rise above 30% and creating a hard ceiling on growth. The brand partnered with Quartile, which identified the core issue as a lack of a structured system for budget allocation and performance optimization.

Quartile rebuilt the account with a performance-driven architecture, organizing campaigns into segmented "books" and launching over 40 dedicated builds for high-priority products. They integrated Amazon Marketing Cloud audiences for more efficient targeting and employed a full-funnel strategy with DSP for remarketing. This solution from Quartile led to a 55% reduction in ACOS, a 17% increase in total sales, and a 33% growth in B2B sales, successfully breaking the tradeoff between growth and efficiency.
