What Is Retail Media and How Can Cross-Border Sellers Use It?

Updated

Retail media is advertising that runs inside a retailer's own digital and physical channels — its website, app, in-store screens, and onsite search results. The defining feature is closed-loop measurement: because the retailer also processes the transaction, it can connect ad exposure to actual purchase data rather than relying on clicks or surveys. For cross-border sellers, this matters because it lets you reach US shoppers at the moment they are already shopping, and judge campaigns by sales rather than impressions. Walmart Connect, described on its site as the international retail media business of Walmart — "美国第一大零售商" (the largest US retailer) — is one example of a network built for this purpose.

How Retail Media Works

The model has three parts:

  • The retailer's owned surface. Ads appear on the retailer's site, app, or in-store. The audience is people already in a shopping mindset, not a general social feed.
  • First-party shopper data. The retailer knows what each shopper has bought and browsed, so targeting and reporting are tied to real purchase behavior.
  • Closed-loop reporting. Ad exposure is linked to the resulting sale, so you can measure sales lift instead of guessing from click-through rates.

That last point is the core difference from most other channels. A social ad can tell you someone clicked; a retail media ad can tell you someone bought.

Retail Media vs. Search and Social Ads

Dimension Retail Media Traditional Search Ads Social Ads
Where the ad runs Retailer's site, app, in-store Search engine results Social feeds
Audience intent High — actively shopping High — actively searching Mixed — browsing and discovery
Measurement Closed-loop, tied to purchases Clicks and conversions you track yourself Clicks, engagement, some conversions
Data source Retailer's first-party purchase data Search query and your own data Platform interest and behavior data
Best fit Driving sales on a specific retailer Capturing existing demand Building awareness and demand

The practical choice: use retail media when you want to convert shoppers who are already on a retailer's platform and need proof that the spend produced sales. Use search and social when you need to create demand or reach people before they start shopping.

How Chinese Sellers Can Use Walmart Connect

Walmart Connect positions itself as an omnichannel retail media business that helps Chinese companies reach US consumers and build global brands. For a cross-border seller, the entry point is typically your existing or planned presence on Walmart's marketplace — retail media amplifies a product listing rather than replacing it.

A workable starting sequence:

  1. Confirm you can sell on the retailer's platform. Retail media usually requires an active product catalog on that retailer. Without listings, there is nothing to advertise.
  2. Pick one retailer network to start. Spreading budget across several networks before you understand one makes results hard to read. Walmart Connect is a reasonable first choice for sellers targeting US shoppers, given Walmart's stated scale.
  3. Set a single goal. Decide whether you are optimizing for sales on a specific product, category visibility, or new-customer acquisition. Different goals change which ad formats and metrics matter.
  4. Launch a small, measurable campaign. Keep the budget and product set narrow so you can attribute results cleanly.
  5. Measure sales lift, not just clicks. The reason to use retail media is the closed-loop data — use it. Compare sales during the campaign against a baseline period.

Common Stumbling Points

  • No listing, no campaign. Retail media depends on the retailer's catalog. Set up your products first.
  • Judging by clicks. The advantage of retail media is purchase-level reporting; optimizing only for click-through wastes that advantage.
  • Too many products at once. A narrow test tells you which products respond to advertising. A broad one tells you little.
  • Assuming it is free or open to anyone. The source material describes the business and its purpose but does not state pricing, minimum spend, or eligibility terms. Check current requirements directly with Walmart Connect before budgeting.

Where to Start

If you already sell or plan to sell on Walmart's marketplace and want to reach US shoppers with measurable, purchase-linked advertising, Walmart Connect is the natural first network to evaluate. Start with one product, one goal, and a baseline you can compare against — then scale what the closed-loop data says is working.
