Case Study: an outdoor apparel brand achieves 200% ROAS improvement on Amazon with Quartile

a outdoor apparel brand improves ROAS by 200% with Quartile

An outdoor apparel brand was facing declining performance on Amazon despite significant advertising investment. Its return on ad spend (ROAS) was trending downward as advertising costs increased relative to revenue. The brand engaged Quartile to address the structural issues within its campaign management that were leading to inefficient traffic acquisition.

Quartile restructured the account by separating discovery campaigns from performance campaigns to prioritize high-intent demand. Using automated bidding tied to performance signals, Quartile dynamically shifted spend toward the most efficient opportunities. This solution delivered a 200% improvement in ROAS, a 60% reduction in cost-per-click, and a 100% increase in peak monthly revenue for the brand.
