Case Study: Relievance Achieves 52% TACoS Improvement with Quartile

How Relievance Broke Into the Competitive Supplements Category on Amazon

Relievance, a US-based fiber supplement brand founded by Dr. Robert A. Ganz, MD, launched on Amazon in the highly competitive Vitamins & Supplements category with no keyword ranking, little review history, and no organic traction. It needed a way to build visibility and sales momentum without getting stuck in the early-stage inefficiency that often comes with launching on Amazon.

Quartile implemented a phased Amazon launch strategy using Sponsored Products and real-time campaign optimization to build algorithmic signals first, then tighten performance and stabilize economics. Within one month, Relievance improved TACoS by 52% and ACOS by 45%, while 71% of ad-attributed sales came from non-branded search; sales volume stayed stable, the product earned a 100+ badge, and ad sales increased 24% with ad spend reduced 33%.
