Why Walmart Marketplace in 2026
Amazon gets the most attention, but Walmart Marketplace has caught up fast:
- 120 million+ monthly unique visitors to Walmart.com
- Lower seller competition: fewer sellers than Amazon means better organic visibility for new entrants
- Walmart's omnichannel edge: In-Store, Pickup, and Delivery options available for eligible listings
- Walmart+ membership growth: 35M+ Walmart+ members prioritise Walmart when shopping online
The biggest opportunity: categories that are saturated on Amazon (home, garden, tools, pet) are far less competitive on Walmart. Brands that move early have a structural advantage.
Eligibility Requirements
Unlike Amazon, Walmart Marketplace has an application process. You need:
- A US business address and US bank account
- A US Tax ID (EIN)
- A product catalog with GTINs (UPCs, EANs)
- Proven ecommerce history (your own site, Amazon, or other channels)
- A fulfilment method ready to go (Walmart Fulfilment Services or self-fulfilled)
Applications are reviewed manually. Typical approval: 2–4 weeks. Rejections are common if your catalog is thin or you have no prior ecommerce track record.
Fulfilment Options
Walmart Fulfilment Services (WFS)
The equivalent of Amazon FBA. You ship inventory to Walmart's fulfilment centres; they pick, pack, and ship to customers.
Benefits:
- 2-day delivery badge on your listings
- Higher Buy Box win rate
- Eligible for Walmart+ free shipping (major conversion driver)
Best for: established sellers with predictable inventory volumes.
Seller-Fulfilled (DSV)
You fulfil directly from your own warehouse or 3PL. You control shipping costs and timelines.
Requirements:
- Must offer at least standard 5-day delivery
- Late shipment rate must stay below 3%
- Cancel-before-ship rate below 2%
Best for: brands with oversized items that don't fit WFS specifications, or those testing Walmart before committing to fulfilment investment.
Listing Optimisation on Walmart
Walmart's search algorithm (Polaris) ranks products differently from Amazon's A9. Key ranking signals:
Title
Walmart titles follow a specific format:
[Brand] + [Product Name] + [Key Feature] + [Size/Count/Variant]
Max length: 75 characters. Unlike Amazon, Walmart penalises keyword stuffing in titles.
Product Description
Walmart gives you 4,000 characters. Use full sentences — Polaris rewards natural language. Include your top 5–8 buyer questions answered in the description body.
Product Attributes
Walmart's category taxonomy is attribute-heavy. Every category has mandatory and recommended attributes. Listings missing mandatory attributes are suppressed.
Common mandatory attributes:
- Brand
- Manufacturer Part Number
- Product Type
- Material (for soft goods)
- Assembled Product Dimensions
Product Images
- Minimum: 1 main image on white background
- Recommended: 6–8 images including lifestyle shots, feature callouts, and size/scale reference
- Main image requirements: white background, product fills 85%+ of frame, no watermarks
Walmart's Buy Box Algorithm
Unlike Amazon, Walmart's Buy Box is heavily price-dependent. The lowest-priced offer with acceptable seller metrics wins most of the time.
Metrics that affect Buy Box eligibility:
- On-Time Delivery Rate (target: >95%)
- Order Defect Rate (target: <2%)
- Valid Tracking Rate (target: >99%)
Price matching: Walmart's automated pricing policy monitors competitor prices. If your item is significantly cheaper elsewhere (including your own website), Walmart may suppress your listing or remove the Buy Box until you match prices. This is Walmart's most common seller complaint — price your products consistently across channels.
Walmart Advertising
Walmart Connect offers Sponsored Products similar to Amazon PPC. Key differences:
- Cost-per-click is lower than Amazon for most categories (less advertiser competition)
- Keyword targeting: Exact, phrase, and broad match — similar to Amazon
- Auto campaigns: Walmart auto campaigns are useful for initial keyword discovery
Start with auto campaigns for 2–3 weeks, then harvest converting search terms into manual exact/phrase campaigns.

Common Mistakes New Walmart Sellers Make
Copying Amazon listings directly Amazon and Walmart have different title formats, attribute requirements, and content policies. Direct copy-paste creates suppressed listings and poor search visibility.
Ignoring attribute completeness Walmart suppresses listings with missing mandatory attributes silently. Run a weekly suppression report to catch these.
Pricing higher than Amazon Walmart's price parity policy means pricing above your Amazon price risks suppression. Maintain price parity or price Walmart slightly lower to win the Buy Box.
No 2-day shipping Without a 2-day delivery badge, conversion rates drop significantly compared to WFS-enrolled competitors. The badge is Walmart's equivalent of Amazon Prime.
