Case Study: an Amazon-focused reseller company achieves 60% YoY sales growth with Quartile

How an Amazon Reseller Turned Buy Box Volatility into 60% YoY Growth

An Amazon-focused reseller of electronics was struggling with growth due to the operational constraints of Buy Box volatility and inventory shortages. Despite having efficient advertising with a strong ACOS, their sales growth was limited because their ads could not convert when their products were ineligible to win the Buy Box. They turned to Quartile for an automated advertising solution that could intelligently adapt to these marketplace conditions.

Quartile implemented a solution that restructured the reseller's campaigns to prioritize high-value products and dynamically align spending with real-time Buy Box eligibility and inventory levels. When items were eligible and in stock, the system increased exposure, and it pulled back during constraints to avoid wasted ad spend. This approach from Quartile led to a 60% growth in total sales YoY, an 86% increase in ad-attributed sales, and a 50% improvement in ACOS, proving that automation could drive scalable, profitable growth.
