Case Study: a leading women’s handbags brand boosts Q4 sales with Quartile

How a Handbags Brand Scaled Holiday Season Growth

Leading Women's Handbags Brand, a women’s accessories brand selling vegan leather handbags on Amazon, struggled to scale efficiently during the crowded holiday season because more than 5,000 ASINs were managed in broad Sponsored Products campaigns. That setup made it hard to prioritize top performers, protect long-tail coverage, and respond quickly as demand shifted in Q4.

Quartile restructured Sponsored Products by grouping products by bag type, moving top-selling ASINs into granular single-ASIN manual campaigns, and using automation to continuously optimize bids and budget allocation while keeping long-tail coverage in bulk campaigns. With Quartile, the brand grew total Q4 sales 94% year over year, increased ad-attributed sales 200%, improved ACOS by 31%, and later expanded the partnership with additional channels.
