Walmart Connect is running third-party lift studies to prove ad performance and pitching the results directly to brands ahead of the holiday shopping surge, according to Digiday. The move bypasses traditional agency relationships and positions Walmart's retail media network as a data-validated alternative to Amazon, using external measurement to document return on ad spend that brands can cite in their own planning.
The lift studies measure incremental sales attributed to ads on Walmart's platform, comparing purchase behavior of exposed shoppers against control groups. Walmart Connect presents these results in direct brand conversations, offering validated proof that ad dollars drove margin-positive transactions. The retailer is positioning the studies as decision-grade evidence for brands allocating Q4 budgets across retail media networks, where attribution models vary widely and self-reported metrics carry less weight.
The mechanism works because third-party validation removes the conflict inherent in platform-reported numbers. When a retailer says its ads work, brands discount the claim. When an independent measurement firm documents lift, the brand can use that figure in internal business cases and compare it across platforms using a common standard. Walmart is effectively arming its sales team with external proof, turning the pitch from "buy our ads" to "here is what happened when comparable brands ran this spend with us." That shift changes the buyer's risk calculation and makes the decision defensible inside procurement reviews.
For a small physical-product brand, the steal is straightforward: commission your own proof before you ask for the bigger buy. If you are pitching a retailer on expanded shelf space, pay for a small test run and document the sell-through rate with timestamped inventory reports from their system. If you are pitching a corporate gifting buyer on a 5,000-unit order, offer to fulfill 500 units to three test departments first, then present the feedback scores and reorder requests in a one-page summary with the buyer's own internal ticket numbers cited. The cost is the margin on the test batch and the time to format the results. The return is a buyer who can forward your proposal with third-party proof attached, which moves it past the internal "maybe" into the budgeted "yes."
If you run growth for a mid-size brand with a real ad budget, the same principle scales: hire the measurement vendor before you commit the flight. Spend $8,000 on a 30-day lift study with a firm like Measured or Keen, run a modest test campaign on a retail media network or Meta, and present the documented ROAS to your CFO or board before you ask for the $200,000 annual allocation. The study becomes the business case. You are not asking for trust in the channel; you are showing incremental revenue per dollar spent, broken out by cohort, with error bars. That document wins budget battles and protects you when the channel underperforms later, because you bought decision-grade evidence at the start.
The broader pattern is that proof moves faster than persuasion in any market where buyers see dozens of similar pitches. Walmart Connect is not offering better ads; it is offering better evidence. The brands that win retail media budgets or retail shelf space or gifting contracts are the ones that make it easy for the buyer to say yes by handing them the number they will need to defend the decision internally. Commissioning external proof is not a marketing expense—it is the cost of removing friction from the buyer's workflow. That cost pays for itself in the first approved order.
Third-party proof turns a pitch into a business case; commission small-scale validation before you ask for the big commitment.

Your next customer won't visit your website. Their AI will.
AI assistants have quietly taken over the first step of buying — they answer from catalogs they can read and shortlist whoever can actually ship. Two questions now decide whether you exist to that buyer: can a machine read your catalog, and can you fulfill the order. Most brands fail one or both and never find out why the orders went elsewhere. The winners of this shift aren't the loudest. They're the most readable. Build for the machine that's about to do the shopping.
