For most of 2024 and early 2025, Walmart Connect was the ad platform DTC brands and third-party sellers treated as an afterthought — a place to dump a small budget after maxing out Amazon Sponsored Products. That calculus has shifted. Walmart Connect crossed $4.4 billion in U.S. ad revenue in 2025, according to eMarketer’s Q1 2026 retail media report, and the platform is now offering targeting capabilities, sponsored display placements, and offsite reach that Amazon advertisers haven’t seen before. More importantly, the cost-per-click economics are still materially cheaper than Amazon’s — a window that won’t stay open forever.
This guide is for Shopify brands selling on Walmart Marketplace, Amazon sellers looking to diversify, and agency operators managing multi-channel retail media budgets. We’ll walk through how to build a Walmart Connect strategy that actually drives incremental revenue — not just incremental spend.
What Makes Walmart Connect Structurally Different From Amazon Ads in 2026?
Before building a campaign structure, you need to understand what you’re working with. Walmart Connect runs on a fundamentally different data model than Amazon. Where Amazon’s ad targeting is built on its own closed purchase graph, Walmart leverages first-party data from 245 million weekly Walmart shoppers — including in-store purchase data from physical Walmart and Sam’s Club locations. That in-store signal is the platform’s most underutilized differentiator.
- Walmart DSP: Programmatic offsite display powered by Walmart’s first-party shopper data, available via managed service or through The Trade Desk’s self-serve Walmart data segment integration
- Sponsored Products: Search-based CPC ads on Walmart.com — the closest analog to Amazon Sponsored Products
- Sponsored Brands: Header banner placements on search results pages, rolled out broadly to self-serve advertisers in late 2025
- Display Ads (onsite): Category and homepage display placements, sold on CPM basis — primarily available to large suppliers but increasingly accessible to marketplace sellers via Connect’s self-serve dashboard
- In-Store Experiences: Digital screens and self-checkout placements — still largely managed-service and $50K+ minimum, but worth flagging for omnichannel brands
The key operational difference: Walmart Connect’s self-serve interface, while improved dramatically after the 2024 platform overhaul, is still less mature than Amazon’s console. Budget pacing, dayparting controls, and negative keyword management all exist — but require more manual oversight than Amazon’s automated bidding infrastructure.
How Do You Structure Your Walmart Connect Campaign Hierarchy?
Campaign architecture on Walmart Connect follows a familiar sponsored-search logic, but the keyword dynamics are different. Walmart’s search algorithm (internally called the Listing Quality Score system) weights in-stock rate and item content score heavily — which means your ad spend is partially wasted if your listings aren’t optimized first.
Step 1: Audit your listing quality before you spend a dollar. Walmart’s Item Content Score should be above 85/100 before you activate Sponsored Products. This means complete product titles, five or more high-resolution images, populated attributes, and a minimum of 10 customer reviews. Use Walmart’s Listing Quality Dashboard in Seller Center to identify gaps. Brands running Helium 10’s Walmart module can pull competitive content scoring data to benchmark against category leaders.
Step 2: Build your keyword foundation with Walmart-specific search data. Don’t port your Amazon keyword list directly. Walmart shoppers search differently — more brand-agnostic, more value-oriented. Pull search term reports from your first two weeks of auto-campaign spend and layer in Walmart’s own Keyword Analytics tool, which shows search volume data at the category level. Tools like Perpetua and Pacvue both support Walmart Connect campaign management and can surface Walmart-native keyword opportunities their models have indexed.
Step 3: Run auto campaigns first, manual second. Unlike Amazon where seasoned sellers often start with manual exact-match campaigns, Walmart’s auto campaigns are genuinely useful for discovery. Walmart’s algorithm surfaces your ads across semantic matches that manual bidding misses. Run auto campaigns for 3-4 weeks, harvest converting search terms, then build manual broad and exact campaigns on top of that data.
Step 4: Structure campaigns by margin tier, not by product category. Your highest-margin SKUs should carry the most aggressive bids. Walmart’s auction dynamics in 2026 still reward early movers — CPCs in categories like home goods, sporting goods, and pet supplies are running 40-60% below Amazon equivalents, according to data shared by Pacvue at their Spring 2026 partner summit.
“We moved 18% of our Amazon PPC budget to Walmart Connect in Q4 2025 and saw a blended ROAS that was 2.3x higher than what we were getting on Amazon in the same categories. The CPCs are still inefficient in Walmart’s favor — but that gap is closing every quarter.” — Jamie Kessler, Head of Marketplace Strategy at Grove Collaborative
What Bidding Strategies Actually Work on Walmart Connect Right Now?
Walmart Connect offers three bidding modes for Sponsored Products: Manual CPC, Automatic Bidding (Walmart optimizes for conversions), and Enhanced Bidding (a hybrid where Walmart adjusts manual bids within a range you set). In Q1 2026, Enhanced Bidding has emerged as the default recommendation from most agency operators running significant Walmart Connect spend.
The reason: Walmart’s conversion data feedback loop is faster than most sellers realize. The platform processes purchase signals from both online and in-store transactions, which means its automated bid adjustments have richer signal than pure e-commerce platforms. Ryan Manus, VP of Retail Media at Tinuiti, noted at the 2026 Shoptalk conference that Enhanced Bidding on Walmart has outperformed manual bidding for 70% of their managed accounts when given a 30-day optimization window.
“The mistake most Amazon-native advertisers make is treating Walmart Connect like a slower, cheaper version of Amazon Ads. It’s not. The auction dynamics are different, the shopper intent signals are different, and the optimization levers are different. You have to learn the platform on its own terms.” — Ryan Manus, VP of Retail Media, Tinuiti
Bid adjustment recommendations by category (Q1 2026 benchmarks):
- Grocery/Consumables: Start at $0.45-$0.75 CPC for broad match; Walmart’s grocery shoppers are high-frequency repeat buyers — invest in share-of-voice early
- Home & Garden: $0.60-$1.10 CPC; highly seasonal, front-load Q1 and Q3 budgets
- Electronics/Accessories: $0.90-$1.80 CPC; more competitive, closer to Amazon parity — focus on exact-match long-tail terms
- Apparel: $0.35-$0.65 CPC; lower competition but also lower conversion rates; use Sponsored Brands to build brand awareness alongside Sponsored Products
- Sporting Goods/Outdoor: $0.55-$0.95 CPC; underserved by large brands, strong opportunity for marketplace sellers
How Do You Use Walmart DSP Without a $50K Managed-Service Budget?
The Walmart DSP has historically been gatekept behind managed-service minimums that put it out of reach for most marketplace sellers. That changed in late 2025 when Walmart expanded its integration with The Trade Desk to allow self-serve activation of Walmart audience segments through TTD’s platform — no Walmart managed-service contract required.
For Shopify brands and mid-market DTC operators already running The Trade Desk, this is a significant unlock. You can now layer Walmart’s in-store purchase segments onto your existing TTD campaigns, targeting shoppers who have purchased in your category at Walmart or Sam’s Club in the last 90 days. This works particularly well for retargeting campaigns targeting high-intent buyers who viewed your Walmart.com listing but didn’t convert.
Step 5: Set up Walmart audience segments in The Trade Desk. Navigate to TTD’s Data Marketplace, search for Walmart Connect segments (listed under Walmart Connect Data), and filter by category affinity or purchase recency. CPMs for Walmart audience segments run $3.50-$6.00 — premium over generic third-party data but justified by the first-party purchase signal quality.
Step 6: Close the loop with Walmart’s attribution reporting. Walmart Connect’s attribution window is a 14-day click, 1-day view default — shorter than Amazon’s 14-day click window but configurable. Make sure your reporting is pulling both attributed sales and new-to-brand metrics before evaluating campaign performance. New-to-brand buyer rate is often the more strategically important number for marketplace sellers trying to build Walmart-native customer bases.
What Are the Most Common Mistakes Walmart Connect Advertisers Make?
- Launching ads before achieving item content score parity. Paid traffic sent to a weak listing is money burned — Walmart’s algorithm will discount your Quality Score and your organic rank simultaneously.
- Using Amazon ACOS targets directly on Walmart. Walmart’s category margins, return rates, and referral fee structures differ enough that your Amazon ACOS benchmarks will mislead you. Build Walmart-specific ROAS targets from scratch using Walmart’s fee calculator in Seller Center.
- Ignoring the review velocity requirement. Walmart’s algorithm significantly boosts listings with 50+ reviews. Budget for a review generation strategy — Walmart’s own Request a Review tool (launched 2025) is the compliant path — before scaling ad spend.
- Neglecting out-of-stock events. Walmart penalizes listings that go out of stock while running active ad campaigns, and the organic rank recovery time is longer than Amazon’s. Connect your inventory management system (Linnworks, Skubana, or Feedonomics) to auto-pause campaigns when inventory falls below a threshold.
- Treating Walmart Connect as a set-and-forget platform. The auction is still thin enough in most categories that manual monitoring catches bid inefficiencies that automated rules miss. Weekly campaign audits are non-negotiable in 2026.
How Do You Measure Incrementality on Walmart Connect Across Online and In-Store?
This is where Walmart Connect genuinely outpaces Amazon: the ability to measure how digital ad spend drives in-store sales. Walmart’s Closed-Loop Attribution reports — available in the Connect dashboard for brands enrolled in the Attribution Beta program — show online-attributed revenue alongside in-store purchase lift for shoppers exposed to your ads.
For omnichannel brands with physical retail distribution, this is operationally valuable data. Jamie Kessler at Grove Collaborative noted they identified a 12% in-store sales lift in markets where their Walmart Connect display campaigns were running at higher impression share — data that would be invisible on any pure e-commerce ad platform.
“The in-store attribution data changed how our leadership team thinks about Walmart Connect. It stopped being a Marketplace line item and became a brand investment with measurable omnichannel ROI. That’s a different budget conversation.” — Jamie Kessler, Grove Collaborative
To access Closed-Loop Attribution, you need to be enrolled as a Walmart Connect advertiser with a minimum of 60 days of campaign history and active Sponsored Products or Display spend. Apply through your Walmart account manager or via the Connect portal under Measurement Settings.
The bottom line for 2026: Walmart Connect is in the window between “early mover advantage” and “commoditized auction.” The brands building category share-of-voice now — while CPCs remain below Amazon parity and competition is still thin in most categories — are the ones who will be defending dominant positions in 2027 when the platform’s scale and advertiser base inevitably catch up to its ambitions. Build the infrastructure now. The cost of waiting is compounding.
