Walmart Rolls Negative Keyword TARGETING.

This was the most awaited feature on Walmart, something that Amazon Advertisers have been using years now. Walmart Connect is rolling out Negative Keywords for every Sponsored Products campaign from July 29, 2026. In plain terms: you'll finally be able to tell Walmart "don't show my ad for this search term."

Say you sell premium products. Right now, your ad might show up when someone searches for "cheap" or "free" — clicks you're paying for that are never going to turn into a sale. Soon, you'll be able to block those searches completely.

What Happens on Day One?

According to Walmart Connect's own documentation, negative keywords apply to both 1P and 3P Marketplace Sponsored Products campaigns, with no approval process required to activate them — you can turn them on and start excluding terms immediately. Industry trackers following the rollout expect measurable ACOS compression within the first two weeks on any campaign that has a real search-term history to work from, since that's exactly the kind of waste this feature is built to catch.

So, What Should You Actually Do?

If you've ever cleaned up an Amazon campaign, you already know this playbook. Here's how to use your first week well:

1. Pull your search report right away. Grab the last 30 days of search-term data. This tells you exactly which searches have been triggering your ads.

2. Find the obvious waste first. Look for terms with zero sales and high spend. Block those first — they're your easiest wins.

3. Block your competitors' names. Don't pay for clicks when someone searches a rival brand's name.

4. Watch for "close but not quite" searches. Some terms convert fine for other brands but just drain your budget. Block those too.

5. Make it a weekly habit. Don't just clean up once and forget about it. Check again at day 7 and day 14 — new problem terms will keep showing up.

6. Know the limits before you dive in. Walmart caps keywords at 80 characters, allows up to 1,000 keyword combinations per ad group, and automatically merges similar keyword spellings into one. Worth knowing before you build a big list.

Bottom Line

This is a genuinely useful update — maybe one of Walmart Connect's best in a while. But here's the real takeaway: the brands that treat this as an ongoing habit, not a one-time cleanup, are the ones who'll actually see their ad costs drop. So — are you going to be checking your search terms weekly, or just once and forgetting about it?
