The shift to self-serve: redefining Onsite Display at Walmart

From Managed to Self-Serve: Why this matters

Onsite Display used to require layers of coordination between retailer, agency, and internal teams, often slowing down execution and limiting flexibility. Self-Serve changes that equation entirely.

With Walmart’s platform, advertisers can build, activate, and optimize campaigns independently, eliminating external dependencies and accelerating time to market. This is particularly impactful in a retail environment where timing is everything, whether you’re capitalizing on seasonal demand or reacting to competitor shifts.

It’s more than just speed. With Self-Serve, advertisers gain control and ownership over:

• Creative execution
• Budget allocation
• Campaign optimization
• Reporting and insights

This level of autonomy aligns with how modern marketing teams operate in a leaner, faster, and increasingly
data-driven fashion.

Meeting shoppers at the moment of intent

One of the most compelling aspects of Onsite Display is proximity to purchase, and Walmart’s platform leans heavily into this advantage.

The ability to reach customers while they are actively browsing, searching, and shopping creates a fundamentally different media opportunity. These are high-intent moments where influence translates directly into conversion.

By combining this real-time intent with robust targeting options, the platform enables advertisers to move beyond broad reach into precision activation.

Self-Serve for Onsite Display reaches the right audiences at the right time, a critical distinction in an increasingly saturated retail media environment.

AI as the optimization engine

Perhaps the most transformative element of the platform is its use of AI-powered, objective-based optimization.

Instead of manually adjusting bids and pacing, advertisers can align campaigns to specific goals, such as awareness or engagement, and allow the platform to optimize accordingly.

The system dynamically adjusts bids in real time based on campaign performance, helping to:

• Maximize impressions efficiently for awareness campaigns
• Drive traffic while controlling cost-per-click for engagement campaigns
• Maintain optimal pacing throughout the campaign lifecycle

This represents a shift toward “hands-on strategy, hands-off execution,” where marketers focus on inputs
and objectives, while the platform automates delivery and optimization.

Measurement that connects to business outcomes

In retail media, measurement is the ultimate differentiator. Walmart’s platform emphasizes closed-loop reporting that connects media exposure to actual sales outcomes.

Key capabilities include:

• Metrics spanning impressions, clicks, conversions, and ROAS, including the ability to view performance by shopping channel such as in-store, online or pickup
• Attribution windows of 14 or 30 days
• Insights into new-to-brand customers and cross-channel performance

This level of reporting goes beyond vanity metrics, enabling advertisers to tie media investment directly to business impact, whether online, in-store, or via delivery channels.
