How a Multi-Brand Household Goods Portfolio Increased ROAS 136% on Walmart

This multi-brand household goods portfolio operates across pest control, rodent control, and cleaning products. The catalog spans multiple brands and product lines, distributed across Walmart and other retail channels.

As a first-party (1P) account, performance is closely tied to inventory availability, with limited visibility into stock levels and sales signals—making scalable growth more complex.

The Challenge

Growth was constrained by factors outside of campaign control.

Frequent inventory limitations disrupted performance across key products. When items went out of stock, campaigns were paused or restricted, reducing visibility and breaking performance momentum.

This created a pattern:

• Inventory dropped → campaigns paused  

• Visibility declined → sales dropped  

• Performance became inconsistent  

At the same time, the 1P setup limited access to inventory and sales data, making it difficult to proactively scale or optimize based on real-time conditions.

The account was stable—but unable to scale reliably.

Why Quartile

In a 1P environment, control is limited—but structure can create leverage.

Quartile identified that manual campaign management was not sufficient in a system where inventory dictated performance. The account needed a way to scale automatically when products were available—without requiring constant intervention.

Walmart’s Promote system provided that opportunity.

By enabling automated campaign creation and standardized bidding, Promote allowed the account to expand coverage dynamically, ensuring that available inventory could immediately capture demand.

The strategy shifted from reactive management to scalable automation.

The Solution

Quartile migrated the account to Walmart’s new Promote-driven campaign structure.

Promote was used as the foundation for campaign expansion, automatically launching campaigns for eligible products and ensuring consistent coverage across the catalog.

This eliminated inconsistencies from legacy setups and standardized bidding across campaigns, improving efficiency and control.

As inventory became available, campaigns could scale immediately—without delays from manual setup or adjustments. This ensured that demand was consistently captured whenever products were in stock.

At the same time, Sponsored Search and Sponsored Brands campaigns were aligned within this structure, reinforcing visibility and supporting performance across the funnel.

The result was a system that could scale with inventory—rather than being limited by it.

Results & Impact

The transformation delivered both scale and efficiency:

• ROAS improved by 136%, significantly increasing return on spend  

• CPC decreased by 47%, improving traffic efficiency  

• Impressions increased by over 200%, expanding visibility across the catalog  

• Ad-attributed sales scaled dramatically, increasing more than 10x year over year  

These gains were achieved while increasing spend and expanding reach—demonstrating that automation and structure enabled scalable, efficient growth.

The account moved from constrained performance to a system capable of capturing demand at scale whenever inventory allowed.

Ongoing Value & Future State

With a scalable, automated structure in place, the account is now positioned for continued expansion.

Quartile continues to refine campaign coverage, optimize bidding, and align performance with inventory availability. The Promote framework provides a durable foundation that supports both efficiency and growth in a constrained 1P environment.
