Case Study: Category-Leading Apparel Brand Drives NTB Growth with Quartile

How a Category-Leading Apparel Brand Proved Streaming TV Drives NTB Growth

Quartile worked with a Category-Leading Apparel Brand, a well-established seller of everyday essentials like underwear and base-layer basics on Amazon. The brand wanted to reach younger shoppers aged 18–44 and prove that upper-funnel media, especially Streaming TV, was driving more than impressions—it needed visibility into new-to-brand growth, consideration, and downstream commerce impact.

Quartile implemented a full-funnel Amazon strategy using DSP, Streaming TV, and Sponsored Products, Sponsored Brands, and Sponsored Display, with Amazon Marketing Cloud used to measure path-to-conversion behavior. The program delivered an 81% lift in wishlist actions from Streaming TV exposure, a 43% increase in add-to-cart rate when DSP worked alongside Sponsored Ads, a 34% increase in multiple purchases, and more than 35,000 incremental branded searches, while also increasing repeat purchase rate by 11% and purchase rate by 8%.
