Case Study: Premium Jewelry Brand meets peak-season profitability targets with Quartile

How a Premium Jewelry Brand Met Profitability Targets in Peak Season

Premium Jewelry Brand, a premium fine jewelry seller in a category dominated by low-priced fashion accessories, needed to protect margins during peak gifting season on Amazon. Facing intense competition, rising bid pressure, and higher gold costs, the brand had to meet a strict profitability target without losing visibility in the most important weeks of the year. Quartile was brought in to help manage Amazon advertising more efficiently under these high-stakes conditions.

Quartile restructured Sponsored Products campaigns, isolated strong competitor keywords using Market IQ, shifted spend to exact-match and single-keyword campaigns, and used Sponsored Brands Video to maintain visibility while communicating premium value. By consolidating campaigns into a single portfolio framework and reallocating budget toward the most efficient formats, Quartile helped the brand cut Total Advertising Cost of Sale by 37.5%, increase conversion rate by 200%, and successfully hit its peak-season profitability threshold.
