How to Advertise on Walmart: Campaign Setup, Bids, and Your First 90 Days
Most guides to Walmart advertising read like platform documentation. This one doesn't. It's built from running active Walmart Connect campaigns for brands doing $500K to $5M+ on marketplace - the patterns that show up over and over, what actually moves the needle, and what kills accounts before they have a chance.
If you're an Amazon seller looking to expand, a brand that just got approved on Walmart Marketplace, or someone who's been running Walmart ads for a few months without traction, this guide covers the full picture: how the platform works, how to structure campaigns, how to approach keywords and bids, and what to expect week by week in your first 90 days.
Why Walmart Advertising Is Different From Amazon (And Why That Matters)
Before any campaign setup, you need to internalize one thing: Walmart Connect is not Amazon PPC with a blue logo. The auction mechanics, the shopper behavior, the algorithm, the data lag - none of it is the same. Brands that treat Walmart like a copy-paste of their Amazon account burn budget and conclude Walmart doesn't work. It works. The approach just has to match the platform.
Three differences that affect every decision you make:
1. The shopper searches differently
Walmart.com shoppers use shorter, more category-level queries. On Amazon, you might optimize for "wireless noise cancelling headphones under 50 dollars." On Walmart, the same shopper types "wireless headphones" or "bluetooth headphones cheap." The search intent is similar but the vocabulary is compressed. This completely changes your keyword list.
2. The data arrives slowly
Walmart has a 48-hour reporting lag on most campaign metrics. Amazon typically shows data within 24 hours. This means you cannot optimize on daily cycles the way you can on Amazon. Brands that check their Walmart dashboard every day and make rapid bid changes based on incomplete data will constantly be chasing noise. Optimization on Walmart is weekly, not daily.
3. Organic rank and paid rank are more intertwined
On Walmart, paid ads don't just generate sales - they directly feed organic rank. The algorithm interprets paid purchase velocity as a signal of product relevance. This means the ROI calculation for Walmart ads is different: you're not just buying clicks, you're buying organic position. A brand that runs disciplined ads for 90 days and builds top-5 organic placement for key terms will eventually be able to reduce ad spend significantly. That's the play.
Walmart Connect at a Glance: What the Platform Actually Offers
Walmart Connect is Walmart's advertising platform, accessible through Seller Center. Here's what's available:
Sponsored Products (Search)
This is the workhorse format and where the overwhelming majority of your budget should go. Sponsored Products show up in Walmart.com search results - at the top, in the middle, and at the bottom of the page. They're triggered by keywords you bid on, and you pay per click. For most brands in the $1,500–$10,000/month budget range, Sponsored Products are 90%+ of the strategy.
Sponsored Brands (Brand Amplifier)
Walmart's equivalent of Amazon Sponsored Brands. These are banner-style placements that appear at the top of search results and feature your brand logo, a headline, and multiple products. They require Brand Portal enrollment and are more relevant once you have multiple SKUs on the platform and some organic traction. Don't prioritize these in launch phase.
Display and DSP
On-site display ads appear across Walmart.com pages beyond search results. Walmart's DSP (Demand-Side Platform) extends reach off-site using Walmart's first-party shopper data. These formats are typically managed by Walmart's own ad team or a certified partner, require higher minimums, and are a separate conversation from your self-serve Sponsored Products campaigns. Most brands shouldn't touch DSP until they have a healthy Sponsored Products program running first.
Before You Run Your First Ad: The Readiness Checklist
Ads don't fix bad fundamentals. If you run Walmart Connect on a weak account, you'll spend money driving traffic to pages that don't convert, and your account health will decline alongside your budget.
Before spending a dollar on ads, confirm these are in order:
- Your listings have Walmart-native titles, bullets, and descriptions - not copied from Amazon
- You have at least 3–5 product images per listing, with a clean white-background hero image
- Your price is competitive - Walmart's algorithm suppresses listings with pricing above market
- You're enrolled in Walmart Fulfillment Services (WFS) or have a 2-day shipping badge - WFS items get Buy Box and placement advantages that non-WFS items don't
- You have at least a handful of reviews on each item you plan to advertise - even 5–10 reviews meaningfully improves conversion vs. zero
- Your account is in good standing with no suppressed listings or policy flags
On reviews: Walmart allows you to import Bazaarvoice reviews from your own website and syndicate reviews from other platforms through their review accelerator program. If you're launching cold, this is worth doing before you start spending on ads. Traffic to a zero-review listing converts poorly and wastes your budget.
Keyword Research for Walmart (Not Amazon)
This is where most Amazon sellers make their first mistake. They pull their top Amazon keywords, paste them into Walmart Connect, and wonder why performance is poor. The terms don't match. The search behavior is different. The data is wrong for the platform.
Walmart keyword research has to start with Walmart data.
Use Helium 10's Walmart module
Helium 10 has a Walmart-specific keyword research tool that pulls actual Walmart search volume - separate from its Amazon data. Start here. Type in your main product category and look at what Walmart shoppers are searching. You'll immediately see the vocabulary difference. The terms are shorter, less feature-specific, and often more brand-driven than what you'd target on Amazon.
Mine your manual broad campaign data
Once your manual broad campaign has been running for 3–4 weeks, pull the search term report. This is real Walmart search data from actual shoppers who clicked your ads. Unlike auto campaigns, you can see every term that triggered your ads and act on it. The terms that generated sales at reasonable spend efficiency move into your manual exact campaign. The terms that generated clicks but no sales get added as negatives. This feedback loop is the core of Walmart keyword optimization.
Look at your organic search term report
Seller Center shows organic search terms that drove impressions to your listing. This data isn't available for bid targeting, but it tells you how Walmart's algorithm already associates your product with searches. Terms where you're getting organic impressions but not converting are strong candidates for paid reinforcement.
A practical filter: If a keyword has strong Amazon volume but isn't showing up in your Walmart auto campaign data after 30 days, treat it as Walmart-unvalidated. It may still be worth testing in broad match, but don't put real budget behind Amazon terms that haven't shown Walmart signal.
Campaign Structure That Actually Works
The number one structural mistake on Walmart Connect is running a single auto campaign and calling it advertising. Auto campaigns are discovery tools. They find terms. They are not optimization vehicles - you can't control match types, you can't push budget toward exact-match winners, and you can't exclude waste at the same granularity you need to run a real account.
Here's the three-campaign structure we use for virtually every brand we launch on Walmart. One thing this structure deliberately excludes: auto campaigns. Walmart auto campaigns don't report the keywords they actually served - which means you can't harvest terms, can't migrate anything into manual, and can't learn from the spend. You're paying for data you never receive. Skip auto entirely and run three manual campaigns from day one.
Set at a modest budget (20–25% of total). Broad match covers keyword variations and finds terms you didn't think to target. Review the search term report every 7 days and harvest converting terms into your exact campaign. Unlike auto, you can see exactly what terms triggered your ads and act on the data.
Populate with the 10–20 highest-intent, proven terms from your keyword research and auto campaign harvest. Exact match only. This campaign gets the most budget (50–60%) because these are the terms where you know the intent and can bid precisely. Optimize bids here based on ROAS and conversion rate. This is where your efficiency comes from.
Phrase match captures searchers who include your keyword within a longer query. Budget is 20–25% of total. Add negatives aggressively from the search term report to prevent this campaign from bleeding into irrelevant territory. Think of it as your controlled reach campaign - tighter than broad, more flexible than exact.
One important note: keep separate campaigns for separate product categories. Mixing a kitchen product and a home goods product into the same campaign makes the search term data impossible to act on. One category per campaign, especially in the early months.
Bidding Strategy: Starting Points and How the Auction Works
Walmart's ad auction is a second-price auction, similar to Amazon's - you bid a maximum CPC, and you pay slightly above the second-highest bid. But there are structural differences that affect how you should approach initial bids.
Walmart's suggested bid is unreliable
Walmart Connect shows suggested bid ranges when you set up keywords. In our experience, these are often inflated in competitive categories and misleadingly low in others. Don't use them as your primary signal. Use your own category data and the starting ranges below, then adjust based on what you actually see.
Starting bid ranges by category type
| Category Type | Starting Exact Bid | Starting Broad Bid | Examples |
|---|---|---|---|
| Low competition | $0.50–$0.75 | $0.35–$0.50 | Niche home goods, specialty food |
| Moderate competition | $0.75–$1.25 | $0.50–$0.80 | Health supplements, baby products |
| Competitive | $1.25–$2.00 | $0.80–$1.25 | Electronics accessories, personal care |
| High intent branded | $1.50–$2.50 | $1.00–$1.50 | Brand name searches, top-of-category |
Start conservative and adjust up. It's easier to increase a bid that isn't getting impressions than to walk back a bid that's burning through budget with no return.
The 48-hour rule for bid changes
Because Walmart's reporting lags by 48 hours, never make back-to-back bid changes on the same keyword within a 48-hour window. You'll be optimizing against incomplete data and will create bid volatility that makes it hard to know what's actually working. Make a change, wait 72 hours minimum before evaluating, then adjust again if needed.
Budget Management: Why Underfunding Is the Biggest Mistake
The most common reason Walmart ads "don't work" is that the brand spent $500–$800/month, got minimal data, made no meaningful impression on organic rank, and concluded the platform doesn't convert. That's not a Walmart problem. That's an underfunding problem.
Walmart's algorithm needs purchase velocity to build rank. If you're running on a budget so thin that you're getting 30–40 clicks a week, the algorithm isn't registering your product as a meaningful player in that category. You need enough volume to generate signal.
Practical budget guidance:
- $1,500–$3,000/month - the floor for generating usable data. You can run, learn, and start building organic rank, but growth will be slow.
- $5,000–$10,000/month - the range where you can build real category momentum. Enough volume to optimize meaningfully and build organic rank at a pace that produces visible results within 90 days.
- $10,000+/month - scaling spend once ROAS is proven. At this level, organic rank gains compound and your cost to acquire organic position drops over time.
One more point on budget: don't cap daily budgets so tight that campaigns exhaust early in the day. Walmart shoppers shop in the afternoon and evening. If your daily budget is gone by noon, you're missing peak conversion hours. Set daily budgets with enough room to run through the day, or use Walmart's dayparting features to concentrate spend on high-conversion windows.
Your First 90 Days: What to Expect Week by Week
This is the part most guides skip. Here's the actual timeline of what a well-run Walmart Connect launch looks like:
All three manual campaigns are live. Broad is running at 20–25% of budget for discovery. Exact and phrase are running with your initial keyword list. ROAS will likely be 1x–2x at best. That's expected - you're buying data, not profit. Do not optimize aggressively yet. The data you need doesn't exist yet. Pull your search term report at the end of week 2 and week 4, note what terms are converting, and start building your harvest list for month 2.
One thing you can act on in this phase: negative keywords. If your manual broad campaign is triggering on clearly irrelevant terms (wrong category, wrong product type), add those as negatives immediately. Don't wait for the 30-day review to stop clear waste.
Now you have real data to work with. Move the proven search terms from your manual broad campaign into manual exact at aggressive bids. Build your negative keyword list from everything in broad that spent without converting. Start adjusting bids on your exact match keywords - raise bids on terms with strong ROAS, lower on terms bleeding spend.
By the end of this phase, ROAS should be trending up. If you started at 1.5x in month one, a healthy month two looks like 2x–3x, depending on category and product margins. Organic rank should also be showing signs of life - check your non-paid search term impressions to see if Walmart's algorithm is starting to associate your products with more terms.
This is where the strategy starts paying off. Your exact match campaigns are refined. You have a strong negative keyword list. Organic rank is improving on your target terms. ROAS should be in the 3x–4x+ range on your best keywords. The question now is scale: which campaigns and keywords are profitable enough to push more budget into?
By day 90, you should also be able to make a clear assessment of which products are working on Walmart and which aren't. Not every SKU will perform - some products just don't have demand on Walmart's shopper base. Concentrating budget on your proven performers and deprioritizing weak ones is a legitimate day-90 optimization.
One of our CPG clients went from $1K/month to $150K/month on Walmart in 8 months - with zero ad spend.
That result came from listing optimization, WFS enrollment, and working directly with a Walmart account manager - not from ads. Which is exactly why we tell every new Walmart client the same thing: ads accelerate a working account, they don't fix a broken one. Get the foundation right first, then use Walmart Connect to pour fuel on it.

A lot of brands measure Walmart ad performance the wrong way and either overclaim results or miss what's actually broken. Here's how to read the numbers correctly.
ROAS vs. TACoS
ROAS (Return on Ad Spend) measures the revenue your ads directly generated divided by what you spent. It's useful but incomplete, because it doesn't account for organic sales that are growing as a result of your paid activity. TACoS (Total Advertising Cost of Sale) divides your total ad spend by your total sales - paid and organic combined. As organic rank builds, TACoS should decrease even if ROAS stays flat, because your organic sales are growing without additional spend.
On Walmart, the TACoS trend over 90 days tells you whether the strategy is working at the account level. A declining TACoS alongside growing total sales is the signal you want.
Impression share matters more early
In launch phase, check impression share on your key terms. If impression share is under 20–30% on your exact match terms, your bids aren't competitive enough to get into the auction regularly. Low impression share means you're not spending enough to build the velocity Walmart's algorithm needs to see.
Don't obsess over ACoS in month one
Early Walmart ads will have high ACoS. That's structural - you're in a data collection phase with sub-optimal relevance scores and no conversion history. Brands that cut campaigns because month-one ACoS is 60–80% are making the same mistake every time. The right benchmark for month one is whether you're generating real search term data and whether organic impressions are ticking up. Efficiency comes in month two and three.
Common Mistakes - and What to Do Instead
- Copy-pasting Amazon campaigns. Build Walmart campaigns from Walmart keyword data. The vocabulary, intent, and search behavior are different enough that an Amazon keyword list will misallocate most of your budget.
- Running auto campaigns at all. Walmart auto campaigns don't report the keywords they served. You're spending into a black box with nothing to harvest. Start manual from day one - broad, exact, and phrase - and own your own data.
- Optimizing on daily data. The 48-hour reporting lag means daily bid changes are based on incomplete numbers. Weekly reviews, minimum 72 hours between bid changes on the same keyword.
- Underfunding and expecting Amazon-level volume. Walmart has less traffic than Amazon. That's also why CPCs are lower. Budget to the platform's reality - $1,500/month is a floor, not a comfortable starting point.
- Advertising without WFS. Non-WFS products compete at a structural disadvantage on Buy Box and placement. If you're not enrolled in Walmart Fulfillment Services, ads are working uphill.
- Chasing ROAS in month one. Launch phase is data and velocity. ROAS optimization is a month-two and month-three activity. Pulling campaigns because early ROAS is below target is the most common way to fail on Walmart.
Frequently Asked Questions
How do I start advertising on Walmart.com?
You need an active Walmart Marketplace seller account in good standing. Once approved, access Walmart Connect through your Seller Center dashboard. Start with Sponsored Products using manual campaigns. Budget at least $1,500/month to generate enough data for meaningful optimization.
How much does it cost to advertise on Walmart?
Walmart Connect uses a cost-per-click model. CPCs range from $0.40–$0.95 in low-competition categories to $1.50–$2.50 in competitive ones. The practical monthly minimum to generate usable data is $1,500–$3,000. Brands serious about Walmart growth should budget $5,000–$10,000/month. For a full breakdown, see our Walmart advertising cost guide.
What is the difference between Walmart Connect and Amazon PPC?
Both are keyword-triggered cost-per-click platforms, but they behave differently. Walmart has lower CPCs, less competition, and slower reporting (48-hour data lag vs. ~24 hours on Amazon). Walmart's algorithm weights organic rank and pricing more heavily, and Walmart shoppers use different search terms than Amazon shoppers. You cannot copy your Amazon campaigns directly.
How long does it take to see results from Walmart ads?
Expect a 60–90 day ramp before campaigns are fully optimized. The first 30 days are data collection. By day 60 you can start tightening match types and cutting waste. By day 90, if you have organic rank building underneath the paid activity, ROAS should be improving. Brands that pull the plug before 90 days almost always fail on Walmart.
Should I use automatic or manual campaigns on Walmart Connect?
Manual only. Skip auto campaigns entirely. Walmart auto campaigns don't report which keywords they actually served, which means you can't harvest terms or learn from the spend. Run manual broad for discovery, manual exact for your proven terms, and manual phrase for expansion. You get the same coverage as auto would give you - with full visibility into what's actually happening.
Can I use the same keywords on Walmart as Amazon?
No. Walmart shoppers search differently - shorter queries, more brand-driven, less feature-specific than Amazon. Use Helium 10's Walmart module to pull actual Walmart search volume, then validate with your own manual broad campaign data. Build a Walmart-native keyword list rather than importing your Amazon targets.
