The tactic is designed to lock spend before Amazon and Target claim budgets, and it signals a shift from placement selling to proof-driven media buys. The retailer is offering brands incremental sales measurement through controlled test-and-control studies that isolate the effect of Walmart's on-site and off-site ads. Brands receive data showing how much additional revenue came from display, search, or video placements compared to a holdout group. Walmart Connect pitches this directly to brand marketers, bypassing agencies in many cases, and frames the study as a pre-commitment tool: brands can validate performance before scaling spend during peak season. The mechanism works because physical product brands need proof at the point of conversion. Retail media sits closer to the transaction than social or search, and lift studies quantify the incrementality that justifies shifting dollars from Facebook or Google. Walmart Connect can show a brand that its sponsored product ad drove **$4.12** in sales for every dollar spent, or that display drove a **22 percent** lift in category purchases, using basket-level data that e-commerce platforms cannot match. That proof becomes the wedge to secure Q4 commitments in August and September, before competitors lock inventory. Target is deploying a parallel play with exclusive bundles and discount-driven promotions, per Modern Retail. The retailer is packaging private-label and national-brand products into curated sets available only at Target, then promoting them through its Roundel ad platform. The exclusivity creates a reason to buy at Target instead of Walmart or Amazon, and the bundling increases basket size while giving brands a differentiated shelf presence they cannot replicate elsewhere. The steal for a small physical-product brand is to run your own micro lift study and use the result to negotiate better co-op terms or retail media placement. Pick one retailer where you have clean sales data. Run a one-month test with a single ad format, search or display, and hold back a matched control group of similar products or regions. Measure the sales difference. If your sponsored product ad on Amazon or Walmart drove a **15 percent** lift in units sold, document it in a one-page PDF with the date range, SKU, and result. Then take that proof to your buyer or retail media rep and say: we know this works, we want to scale it, and we need you to match our last cost-per-click or give us Q4 rate protection. The data makes the ask credible. You can run this for under **$2,000** in ad spend if you control the test yourself. Use Amazon's or Walmart's self-serve ad console, segment by ZIP or category, and export the sales report at the end of the month. Compare it to your baseline. The result does not need to be perfect; it needs to be real and repeatable. Retail media reps respond to brands that measure, because most brands still buy on hope. The broader pattern is that retail media is maturing from a placement game to a performance game, and the brands that can prove incrementality will capture the inventory and the margin. Walmart Connect is betting that measurement wins the spend war, and smaller brands can use the same logic to win their own budget fights before the holiday freeze. ## The takeaway Run a controlled lift test on one retailer, document the sales increase, and use that proof to lock better rates before Q4. --- ## Publisher **Hako Shikin LLC** — Virginia Beach, Virginia.
