Case Study: Walmart sustains growth and visibility with Quartile

Walmart boosts ad-attributed sales 38% with Quartile

The customer, a multi-brand portfolio operating exclusively on Walmart, faced significant instability due to frequent inventory shortages and loss of Buy Box on high-performing products, especially during peak periods. This volatility disrupted campaign delivery and limited scale. With limited visibility into real-time stock data, managing both a seasonal party supplies brand and an evergreen educational toys brand was a major challenge. Quartile was engaged to implement a solution using Walmart Sponsored Search.

Quartile implemented a real-time, product-level optimization strategy. Instead of static campaigns, they used flexible budgets to dynamically reallocate spend toward in-stock, high-converting products. For the seasonal brand, assortments were refreshed ahead of key events, while the evergreen line's strategy focused on maintaining consistent visibility. This approach resulted in a 38% increase in ad-attributed sales for the educational line and a 94% increase in impressions. Quartile successfully maintained efficient ROAS and sustained performance throughout critical retail periods despite ongoing inventory constraints.
