Walmart Sponsored Search Ads: A Guide for Amazon Sellers Expanding to Walmart

If you already sell on Amazon, Walmart is usually the next marketplace on your list. It has a massive shopper base, fewer sellers in most categories, and a search results page that is now just as ad-driven as Amazon’s. Walmart places sponsored results at the very top of search and mixes more of them into the product grid than it did a few years ago. Products that are not advertised are easier to miss.

That is why Walmart sponsored search ads matter so much for new Walmart sellers. Ads are often the fastest way to get early clicks, sales, and reviews while your items build organic ranking. The good news for Amazon sellers is that you already understand the basics of retail search advertising. The challenge is that Walmart is not a copy of Amazon. Its eligibility rules, placements, campaign settings, and reporting have important differences, and sellers who paste their Amazon campaigns into Walmart often waste budget in the first few months.

This guide explains how Walmart sponsored search ads work, how they compare with Amazon Sponsored Products and Sponsored Brands, how to set up your first campaign, what it costs, and how to build a structure that grows profitably.

What Are Walmart Sponsored Search Ads?

Walmart sponsored search ads are Walmart’s self-serve, keyword- and relevance-based advertising for products sold on Walmart.com. They are part of Walmart Connect, Walmart’s retail media business, and marketplace sellers access them through the Advertising section of Seller Center.

The model will feel familiar if you run Amazon PPC:

• You choose products to promote and set a budget.
• You bid on clicks, either letting Walmart choose the keywords (automatic targeting) or choosing them yourself (manual targeting).
• Walmart runs an auction each time a shopper searches or views a page. Relevance and your bid together decide which ads appear and where.
• You pay per click, not per impression.

The biggest difference is how closely Walmart ties ad eligibility to the health of the item itself. On Walmart, an ad will not serve if the product is out of stock or another seller holds the Buy Box. Relevance also depends heavily on the quality of your item content. So advertising on Walmart is as much about getting your listings, pricing, and inventory right as it is about bids and keywords.

Walmart Sponsored Search Ad Formats

Walmart sponsored search ads come in three formats. Each one has a different job and different eligibility rules.

Sponsored Products

Sponsored Products promote individual items. They look like regular product listings with a small “Sponsored” label and appear in search results, on item pages, and in other shopping areas of the site.

• Best for: driving sales of specific items, launching new products, and defending your own listings
• Who can use it: any marketplace seller with eligible items. Brand registration is not required.
• Amazon equivalent: Amazon Sponsored Products

For most Amazon sellers moving to Walmart, Sponsored Products should carry the majority of the budget at the start.

Sponsored Brands

Sponsored Brands show your brand logo, a custom headline, and a small group of your products at the top of relevant search results. They build brand awareness and send shoppers to multiple items at once.

• Best for: brand visibility, branded search defense, and promoting a product range
• Who can use it: brand owners who are registered in the Walmart Brand Portal and hold a registered trademark with the USPTO. Walmart also limits the format to brand owners based in certain countries, including the United States, China, Hong Kong, the United Kingdom, and India.
• Amazon equivalent: Amazon Sponsored Brands (product collection)

Sponsored Videos

Sponsored Videos place a short product video directly in search results. Video stands out in a crowded results page and helps explain products that need demonstration.

• Best for: products with a visual or “how it works” story, and categories where shoppers compare several similar items
• Who can use it: the same brand owners who qualify for Sponsored Brands
• Amazon equivalent: Amazon Sponsored Brands video

If you already have Amazon video creative, you can often adapt it for Walmart. Check Walmart’s current creative specifications and remove anything that mentions Amazon, Prime, or Amazon-specific badges.

Where Walmart Sponsored Search Ads Appear

Walmart sponsored search ads can appear in several places on Walmart.com and the Walmart app. Knowing the placements helps you read your reports and set bid multipliers.

• Search in-grid: your product appears inside the main search results grid, including the top rows. This is usually the highest-intent placement.
• Search carousel: a row of sponsored products shown within or below the search results.
• Item page (Buy Box area): an ad shown on a competitor’s or related product page, near the add-to-cart area.
• Item page carousels: rows of sponsored products further down product pages, such as “similar items” sections.
• Browse, homepage, and stock-up pages: additional placements where Walmart shows relevant sponsored items to shoppers who are browsing rather than searching.
• Top of search (brand placements): Sponsored Brands and Sponsored Videos appear in prominent positions at the top of relevant search results.

Placement access depends on the campaign type. Automatic campaigns can reach both search and item page placements. Manual campaigns are focused on search results, which makes them better for controlled keyword bidding.

Walmart Sponsored Search Ads vs Amazon Sponsored Ads: Key Differences

This is the section most Amazon sellers need. Many of your skills carry over, but several key mechanics are different.

What Transfers Directly From Amazon

• Keyword research habits: Your best converting Amazon search terms are a strong starting list, as long as you confirm them with Walmart data.
• The auto-to-manual workflow: Run automatic campaigns to discover terms, then move winners into manual campaigns with tighter control.
• Match type logic: Broad finds new terms, phrase balances reach and control, and exact gives you precise bidding on proven terms.
• Negative keywords: Blocking irrelevant and unprofitable terms works the same way and matters just as much.
• Break-even thinking: Calculating the most you can spend per sale still sets your bid and ROAS targets.

What Works Differently on Walmart

• Item health controls ad delivery: Losing the Buy Box or running out of stock switches ads off. On Amazon, sellers often watch ads and inventory separately. On Walmart, they are one system.
• Relevance is stricter: Walmart wants sponsored results to match the search closely. An item that has no organic relevance for a keyword will struggle to win that keyword with ads alone, no matter how high the bid.
• Shoppers behave differently: Walmart shoppers are often more price-focused and value fast, free shipping. Price and delivery promise affect click-through and conversion as much as ad copy does.
• Reporting looks different: Attribution windows, report names, and data delays are not the same as Amazon’s. Do not compare Walmart ROAS and Amazon ROAS side by side without adjusting for this.
• Volume is lower: Many keywords get less traffic on Walmart, so campaigns need more time to gather statistically useful data.

If you are still deciding how much to invest in Walmart compared with Amazon, our guide on selling on Walmart vs Amazon explains the wider differences in fees, competition, and growth potential.

Eligibility: What Your Items Need Before Ads Will Serve

Before you spend a dollar on Walmart sponsored search ads, make sure your items can actually serve. Many new Walmart sellers launch campaigns and see few impressions because the items were never eligible.

Sponsored Products Requirements

• Published on Walmart.com: the item must be live, not unpublished or under review.
• In stock: if inventory hits zero, the ad stops.
• Winning the Buy Box: if another seller offers the same item at a better price or with a faster delivery promise and wins the Buy Box, your ad will not serve.
• Category relevance: the item should belong to the same category and product type that shoppers see for that search.
• Organic relevance for in-grid placements: Walmart has used an organic relevance threshold for search in-grid ads, where an item needs to rank within roughly the top 128 organic results for the search term. In practice, if your listing barely mentions a keyword, ads alone will not place it there.

Sponsored Brands and Sponsored Videos Requirements

• Registered brand owner in the Walmart Brand Portal
• Registered trademark with the USPTO
• Eligible business location based on Walmart’s current list of supported countries
• Eligible items that meet the same Sponsored Products rules above

Item Readiness Checklist

Use this checklist before launch:

1. Listing quality: Check the Listing Quality dashboard in Seller Center. Improve titles, descriptions, key features, attributes, and images until your top products score well. Walmart titles follow different rules than Amazon titles, so rewrite them instead of copying them.
2. Complete attributes: Walmart relies heavily on structured attributes for search and filters. Missing attributes reduce relevance.
3. Competitive price: Compare your Walmart price with your own Amazon price and with competing Walmart sellers. Walmart can flag or reduce the visibility of items priced well above other marketplaces.
4. Reliable inventory: Keep enough stock to avoid ads switching off during a promising run.
5. Fast shipping: Walmart Fulfillment Services (WFS) or reliable two-day shipping can improve conversion and make your offer more competitive.
6. Reviews: Products with a few reviews convert better than products with none. Plan for reviews from your first sales.

Listing quality on Walmart works much as it does on Amazon, where strong titles, images, and content improve both ranking and ad conversion. Our Amazon SEO and listing optimization guide covers the content principles that also apply when you adapt listings for Walmart.

How to Set Up Your First Walmart Sponsored Search Campaign

The exact screens change over time, but the setup flow for a Sponsored Products campaign usually follows these steps.

Step 1: Open Advertising in Seller Center

Log in to Walmart Seller Center and go to the Advertising section. Select Sponsored Search to open the Walmart Connect advertising console. The first time, you will accept the advertising terms and add a billing method.

Step 2: Create a New Campaign

Choose to create a Sponsored Products campaign. Then select a targeting type:

• Automatic targeting: Walmart matches your items to relevant searches and pages. This is the best starting point because it collects data quickly with very little setup.
• Manual targeting: You choose keywords, match types, and bids. Use this once you know which terms convert.

Step 3: Set Name, Dates, and Budget

Use a clear naming convention, such as “SP | Auto | Product Name” or “SP | Manual | Exact | Product Name.” Set a start date, an optional end date, a daily budget, and a total budget. Walmart sets minimum daily and total budgets in the console, and these minimums have changed over the years, so confirm the current figures when you build the campaign.

Step 4: Choose Placements and Bid Multipliers

For manual campaigns, choose which search placements to include. Search in-grid is always included, and the search carousel can be added for extra reach. Both campaign types offer bid multipliers, such as raising bids for certain placements or devices. Start with no multipliers or small ones, and adjust after you see placement data.

Step 5: Build Ad Groups and Add Items

Create an ad group and add the items you want to promote. Group items that are closely related, such as the same product in different sizes or colors. Avoid mixing unrelated products in one ad group, because one bid or keyword list will not suit all of them.

Step 6: Add Keywords and Bids (Manual Campaigns)

For manual campaigns, add keywords and choose a match type for each. Use Walmart’s keyword suggestions together with your proven Amazon search terms. Set a bid for each keyword based on your break-even numbers, not just the suggested bid.

Step 7: Review and Launch

Check that every item is published, in stock, and winning the Buy Box. Then launch the campaign and leave it alone for at least a week or two before making large changes. Walmart data can take time to settle, and early changes make it harder to see what is working.

How Much Do Walmart Sponsored Search Ads Cost?

There is no fixed price for Walmart sponsored search ads. You set your own budget and bids, and you pay only when shoppers click.

What Drives Your Cost Per Click

• Competition for the keyword: more advertisers bidding on the same term pushes CPCs up.
• Relevance: highly relevant items can win placements more efficiently.
• Placement: top-of-search and high-intent placements usually cost more.
• Category and season: competitive categories and peak periods, such as back-to-school and the holiday season, raise costs.

In many categories, Walmart CPCs are lower than Amazon’s because fewer sellers advertise. However, keyword volume is also lower, so a lower CPC does not automatically mean better results.

Budget Planning for a First Campaign

Plan your budget around a test period rather than a single month. A sensible approach for Amazon sellers is:

1. Pick three to five products that already sell well on Amazon, have strong reviews, and have healthy margins.
2. Fund an automatic campaign for the first three to four weeks so it gathers enough clicks to make decisions.
3. Add manual campaigns for proven keywords once you have Walmart data.
4. Scale gradually by increasing budgets on campaigns that meet your ROAS target.

Calculate Your Break-Even ROAS

Walmart reports return on ad spend (ROAS), which is ad-attributed sales divided by ad spend. Before you set bids, calculate the lowest ROAS you can accept without losing money.

Illustrative example:

• Selling price on Walmart: $30.00
• Product cost, Walmart referral fee, fulfillment, and other costs: $21.00
• Profit before advertising: $9.00
• Break-even ACoS: $9.00 ÷ $30.00 = 30%
• Break-even ROAS: $30.00 ÷ $9.00 = 3.33

In this example, any campaign with ROAS above 3.33 is profitable on a per-sale basis, and any campaign below it is losing money on ad-driven sales. You may accept a lower ROAS during launch to build sales history and reviews, but set that as a deliberate, time-limited decision.

Walmart’s referral fees, fulfillment costs, and prices often differ from Amazon’s, so calculate break-even numbers separately for each marketplace. If ACoS and ROAS conversions are new to you, our complete guide to Amazon ACoS explains the formulas and benchmarks in more detail.

Campaign Structure: Adapting Your Amazon PPC Playbook

A clean structure makes Walmart sponsored search ads easier to manage and optimize. The goal is not to copy your Amazon account. The goal is to apply the same principles to Walmart data.

Start With Automatic Campaigns

Create one automatic campaign per product or per closely related product group. Automatic campaigns help you:

• Discover which searches Walmart matches your items to
• Reach item page placements that manual campaigns cannot
• Collect click and conversion data quickly

Run them for at least three to four weeks before concluding.

Build Manual Campaigns From Proven Terms

Once you have data, move your best terms into manual campaigns:

• Exact match campaign: your proven, highest-converting keywords, with your strongest bids
• Phrase match campaign: important keyword themes where you want controlled reach
• Broad match campaign: discovery of new terms at lower bids

Keep the automatic campaign running at a lower bid as an ongoing discovery tool.

Use Your Amazon Keyword Data Carefully

Your Amazon search term data is valuable, but treat it as a hypothesis, not a final list:

• Start with your top converters: Add your best-performing Amazon keywords to a manual campaign and see how they perform on Walmart.
• Remove Amazon-specific language: Terms that include Amazon, Prime, or Amazon brand names do not belong in Walmart campaigns.
• Expect different search behavior: Walmart shoppers may use more generic, price-led, or everyday terms than Amazon shoppers.
• Validate before scaling: A keyword that converts on Amazon may not convert on Walmart if price, reviews, or competition differ.

Our expert guide to Amazon PPC keyword research explains how to build and prioritize keyword lists, and the same process works for Walmart once you swap in Walmart data.

Add Negative Keywords From Week One

Negative keywords keep your budget from going to searches that don’t convert. Add them from the start:

• Competitor brand names you do not want to target
• Irrelevant product types, sizes, or uses
• Terms that have spent well above your break-even cost without a sale
• Exact keywords from your manual campaigns, added as negatives in auto or broad campaigns to avoid competing with yourself

The logic is the same as on Amazon. Our guide on finding negative keywords shows you how to spot wasteful terms in your reports.

Use Bid Multipliers After You Have Data

Placement and device multipliers can push budget toward what converts. For example, if search in-grid converts much better than item page placements, raise the multiplier for in-grid. Make these changes only after you have enough data from each placement.

Add Sponsored Brands and Videos Once Sponsored Products Work

When your Sponsored Products campaigns are profitable, and your brand is registered, add Sponsored Brands to protect branded searches and promote your range. Then test Sponsored Videos for products that benefit from demonstration. These formats work best when the products they feature already convert well.

Metrics and Reporting to Track

Walmart sponsored search ads give you plenty of data, but a few metrics drive most decisions.

Reporting Tips for Amazon Sellers

• Check the attribution window: Walmart attributes sales over a longer window than Amazon uses for seller Sponsored Products. Compare like with like before judging which marketplace performs better.
• Allow for data delays: Recent days can look weaker before late conversions are counted. Make decisions on settled data.
• Review keyword and item reports weekly: Look for keywords to raise, lower, pause, or add as negatives, and items that are spending without converting.
• Watch total Walmart sales, not just ad sales: Advertising should help your items earn organic ranking over time. If total sales rise while ROAS stays healthy, the program is working.
• Track Buy Box and stock alongside ads: Sudden drops in impressions are often caused by lost Buy Box or low inventory, not by the campaign itself.

Common Mistakes Amazon Sellers Make on Walmart

These are the most common reasons Amazon sellers struggle with Walmart sponsored search ads.

1: Copying Amazon Campaigns Exactly

Pasting your full Amazon structure and keyword lists into Walmart creates too many campaigns with too little data. Start with fewer campaigns and build from Walmart results.

2: Advertising Items That Are Not Ready

Running ads on items with weak content, missing attributes, or few images wastes money. Fix listing quality first, then advertise.

3: Ignoring the Buy Box and Inventory

If another seller wins the Buy Box or your stock runs out, your ads stop. Many sellers think their campaign failed when the real problem was price or inventory.

4: Using Amazon ACoS Targets on Walmart

Your Walmart margins, fees, and prices are not the same as on Amazon. Use Walmart-specific break-even numbers to set targets.

5: Making Changes Too Quickly

Walmart keywords often have lower volume. Cutting bids or pausing keywords after a few days can kill campaigns that would have performed with more data. Give campaigns time before making major decisions.

6: Skipping Negative Keywords

Without negatives, automatic and broad campaigns can spend heavily on irrelevant searches. Review search and keyword data weekly and block waste early.

7: Pricing Higher on Walmart Than Elsewhere

Walmart shoppers compare prices closely, and Walmart pays attention to how your price compares with other marketplaces. A higher price on Walmart can hurt Buy Box eligibility, conversion, and ad results at the same time.

When to Get Help Managing Walmart Ads

Many Amazon sellers can run Walmart sponsored search ads in-house, especially with a small catalog. Consider outside help when:

• Your team is already stretched managing Amazon
• You have a large catalog and need a clear plan for which items to advertise first
• Your campaigns are spending but not reaching break-even ROAS
• Your items keep losing the Buy Box or going out of stock
• You want Walmart and Amazon advertising, pricing, and inventory managed together

A strong partner looks beyond ad metrics. They should improve item quality, pricing, inventory, and fulfillment alongside your campaigns, because on Walmart those factors decide whether ads can serve at all. Our Walmart account management services cover advertising, catalog, and operations together, and our Amazon PPC agency team applies the same performance discipline to your Amazon campaigns.

Conclusion

Walmart sponsored search ads give Amazon sellers a fast way to gain visibility, sales, and reviews on a fast-growing marketplace. The basics will feel familiar, with pay-per-click bidding, automatic and manual campaigns, match types, and negative keywords. But Walmart has its own rules. Ads only serve when items are published, in stock, and winning the Buy Box, relevance is stricter, and reporting works differently from Amazon.

The best approach is to start focused. Prepare three to five strong products, launch automatic campaigns, calculate Walmart-specific break-even ROAS, and build manual campaigns from real Walmart data. Then add Sponsored Brands and Sponsored Videos once your core campaigns are profitable.

If you’re looking for a partner to manage your Walmart and Amazon advertising under one strategy, AMZDUDES, as a full-service Amazon agency, can help.

Frequently Asked Questions

What are Walmart sponsored search ads?
Walmart sponsored search ads are pay-per-click ads that promote your products, brand, or video in Walmart.com search results and on item pages. They are managed through Walmart Connect in Seller Center. The three formats are Sponsored Products, Sponsored Brands, and Sponsored Videos. You set your own budget and bids, and you only pay when a shopper clicks on your ad.

Do I need brand registration to run Walmart sponsored search ads?
Not for Sponsored Products. Any marketplace seller with eligible items can run them. Sponsored Brands and Sponsored Videos are different. They require you to be the brand owner, registered in the Walmart Brand Portal, with a registered USPTO trademark and a business based in one of Walmart’s supported countries.

Why are my Walmart ads not getting impressions?
The most common causes are that the item is out of stock, not published, or not winning the Buy Box. Low relevance is another cause, especially when the listing does not strongly match the keyword. Bids that are too low or tight budgets can also limit delivery. Check item health first, then review keywords, bids, and listing content.

Are Walmart ads cheaper than Amazon ads?
In many categories, Walmart CPCs are lower because fewer sellers advertise. However, Walmart also has less search volume for many keywords, so you may get fewer clicks overall. Costs vary by category, season, and competition. Judge Walmart ads by profitability against your own break-even ROAS rather than CPC alone.

Can I use my Amazon keywords on Walmart?
Yes, as a starting point. Your best-converting Amazon search terms are useful for building your first manual campaigns. Remove anything Amazon-specific, then test the terms on Walmart. Walmart shoppers search differently in some categories, so let Walmart’s own performance data decide which keywords you keep and scale.

How long does it take to see results from Walmart sponsored search ads?
Most campaigns need three to four weeks to gather enough data for confident decisions, and sometimes longer for low-volume keywords. Early results can appear within days, but optimization and steady profitability usually take one to three months. Item quality, pricing, reviews, and inventory all affect how fast results build.

Can AMZDUDES manage Walmart sponsored search ads for Amazon sellers?
Yes. AMZDUDES manages Walmart sponsored search ads alongside Amazon advertising for brands expanding to Walmart. We prepare items for advertising, build campaigns from real Walmart data, set targets around your break-even ROAS, and align pricing and inventory across both marketplaces so your ads keep serving and stay profitable.
