Case Study: Karparts Scales Walmart Advertising Efficiently with Quartile

How Karparts Scaled Walmart Connect Advertising Across an 800K+ SKU Catalog

Karparts, a high-volume automotive parts seller on Walmart, managed an 800K+ SKU catalog with fitment-specific products that required accurate advertising at extreme scale. As the assortment grew in large batches, the team needed a way to launch new SKUs quickly while avoiding inefficient spend and keeping performance under control. Quartile helped support Walmart Connect advertising across this complex catalog.

Quartile implemented a standardized, automated campaign structure to activate large SKU sets quickly, prioritize products with stronger performance signals, and address retail readiness issues before scaling spend. As a result, Karparts improved TACoS by 73% and increased ROAS by 175%, while maintaining stable advertising performance across its 800K+ SKU catalog.
