Walmart Connect shipped negative keywords for Sponsored Products on July 29, letting advertisers block their ads from showing against search terms that do not convert. It is a real feature, it works the way advertisers asked for, and I think the trade coverage calling it overdue is right. I do not think it does what the applause implies it does, which is close the gap between Walmart’s retail media business and Amazon’s.
What actually shipped
According to Walmart Connect’s own announcement, advertisers can now exclude search terms at the campaign and ad group level using two match types: negative exact-match, which blocks a search only when it word-for-word matches the excluded term, and negative phrase-match, which blocks any search containing that full phrase regardless of what surrounds it. It works on manual campaigns and on automatic campaigns running fixed bidding, and it is available directly in the Walmart Connect Ad Center and through partner platforms. Walmart Connect frames the benefit plainly: it offers “a higher level of control, allowing the blocking of low-performing or misaligned terms without unintentionally filtering out related high-value traffic.”
That is a legitimate improvement. Every performance marketer who has run Sponsored Products knows the frustration of bleeding budget on a search term that technically matches but never converts. Negative keywords are table stakes on Amazon and on Google Search, and Walmart advertisers have been asking for this specific control for years.
The strongest case for why this matters more than it sounds
Before I make my argument, I want to give the counter-case its due, because it is a good one. Retail media agencies have been vocal that keyword exclusion was not a nice-to-have feature gap but a genuine budget-efficiency blocker, one of the most-cited reasons advertisers held back incremental Walmart spend relative to Amazon. If a real dollar amount of wasted spend was sitting on the table because of one missing control, then shipping that control is not incremental, it is structural. Reasonable people in retail media are treating this as a meaningful unlock, not a footnote.
I take that seriously. But I think it proves a narrower point than the celebration suggests.
Why feature parity is not competitive parity
Amazon’s advantage over Walmart in retail media was never primarily about which targeting controls existed in the ad console. It is about search intent volume, a decade of DSP integration depth, and an off-Amazon ad network that reaches audiences Walmart’s ad business still cannot touch at the same scale. Negative keywords make Walmart’s existing ad spend more efficient. They do not create new demand, and they do not change how much intent-rich search traffic flows through walmart.com relative to amazon.com in the first place. A brand that shifts budget to Walmart because keyword waste is now controllable is optimizing a smaller pool more carefully. It is not choosing a bigger pool.
This is the pattern across retail media generally: feature-gap closures get covered as competitive moves when they are really operational catch-up. Walmart closing a “years-long feature gap,” in the trade press’s own words, is itself the tell. A years-long gap on a table-stakes control is not a sign of an ad platform that is closing in on the leader. It is a sign of how far behind the tooling had fallen while the underlying scale gap stayed exactly where it was.
What it means for the marketing leader
If you run retail media budgets, use negative keywords the day they are available to you. There is no reason to leave spend on non-converting terms while Walmart’s product team finishes rolling the feature out to more campaign types. But do not let a UI parity story change your channel-mix math. The decision of how much budget belongs on Walmart versus Amazon versus a growing retail media network should still be driven by where your actual audience’s purchase intent lives, not by which platform most recently shipped a control the others already had. Efficiency gains inside a channel and share-of-wallet gains between channels are different problems, and retail media coverage keeps treating the first as evidence of the second. Walmart’s own move into streaming ad inventory through its Vibe.co acquisition is the more consequential scale play to watch, and it says more about how Walmart intends to close the gap than a keyword-exclusion tool does. The same logic applies across the supply side, where ad decisioning is migrating toward the platforms that control inventory quality, not just the ones with the tidiest targeting console.
Walmart Connect deserves credit for listening to advertisers and building what they asked for. It does not deserve credit for narrowing a gap that was never about this feature to begin with.
