Complete listing requirements, feed specifications, and optimization tips for Walmart Marketplace.
Walmart Marketplace is one of the fastest-growing e-commerce platforms in the United States, leveraging Walmart's massive retail footprint of over 4,700 stores and a monthly online audience exceeding 120 million unique visitors. Launched in 2009 and significantly expanded from 2016 onward, Walmart Marketplace allows approved third-party sellers to list their products alongside Walmart's own inventory on Walmart.com. Unlike Amazon, Walmart Marketplace operates on an invitation and approval basis, which means the seller base is more curated, resulting in less competition per listing and higher average conversion rates for qualified sellers.
Listing products on Walmart Marketplace requires compliance with Walmart's strict product content standards, known as the Listing Quality Score. Each product listing must include a rich, keyword-optimized title, detailed shelf and short descriptions, high-quality images, accurate product identifiers (UPC, GTIN, or ISBN), and precise category attributes. Walmart's search algorithm heavily factors in listing quality, price competitiveness, and fulfillment speed when determining organic search rankings. Sellers who maintain high Listing Quality Scores and competitive pricing benefit from significantly better visibility in Walmart's search results and category browse pages.
Walmart provides sellers with a comprehensive suite of tools through Seller Center, including bulk product uploads via spec files and API integrations, Walmart Fulfillment Services (WFS) for warehousing and shipping, Walmart Connect for sponsored advertising, and robust analytics through the Seller Center dashboard. The platform supports product data submission via category-specific spec files (Excel-based), direct API integration through the Walmart Marketplace API, and solution provider integrations. Connecting a PIM system to Walmart Marketplace enables sellers to maintain consistent, high-quality product data, automate listing updates, and ensure compliance with Walmart's continuously evolving content standards across their entire catalog.
Required and optional fields for product listings on this marketplace
The product name is the most important element for search visibility on Walmart. It must follow Walmart's title formula and should not contain promotional phrases, all caps, or special characters. Each word should be capitalized except for articles, prepositions, and conjunctions. Titles must accurately describe the product and should not include information about free shipping, pricing, or seller-specific details.
KitchenAid Professional 5-Quart Stand Mixer with Pouring Shield - Empire RedThe shelf description is the main product description that appears on the product detail page. Walmart encourages rich, well-formatted HTML descriptions with paragraphs, bullet points, and bold text to highlight key features. The description should provide comprehensive information about the product's features, benefits, materials, and use cases. Avoid including contact information, URLs, or references to other retailers.
<p>The KitchenAid Professional 5-Quart Stand Mixer is designed for serious home bakers who demand performance and durability...</p>The short description appears as key features near the top of the product detail page. Walmart requires this to be formatted as an HTML unordered list with 3 to 10 bullet points. Each bullet should highlight a unique product benefit or feature. Focus on the most compelling selling points that differentiate the product from competitors.
<ul><li>Professional-level 475-watt motor handles heavy mixing tasks with ease</li><li>5-quart polished stainless steel bowl with comfortable handle</li></ul>The main image must feature the product on a solid white background with no text overlays, watermarks, or borders. The product should fill at least 85% of the image frame. Additional images should showcase the product from multiple angles, in real-life usage scenarios, and with informational callouts. High-resolution images that meet the 2000x2000 pixel recommendation enable zoom functionality, which improves customer confidence and conversion rates.
Main image: product on white background. Additional: lifestyle, feature callouts, back/side views, size comparisonThe listing price must be competitive. Walmart actively enforces its Pricing Rules policy, which compares your price (including shipping) against the same product on other major retail sites. If Walmart detects a significantly lower price elsewhere, the listing may be unpublished or suppressed. Sellers should monitor pricing across channels and ensure their Walmart pricing is at or near the lowest advertised price to avoid compliance issues.
349.99The brand name must be consistent across all listings for the same brand. Walmart verifies brand information and may require brand authorization documentation for certain categories. For generic or unbranded products, sellers should use their own brand name or indicate 'Unbranded' as appropriate. Brand consistency helps build trust and improves search relevance.
KitchenAidA valid product identifier is required for every item listed on Walmart Marketplace. Walmart validates product identifiers against the GS1 database, so barcodes must be legitimately purchased from GS1 or an authorized distributor. Unlike Amazon, Walmart does not currently offer a general GTIN exemption program, making valid product identifiers essential for all listings. Duplicate or invalid GTINs will result in listing rejection.
883049299495Products must be assigned to the correct Walmart product type, which determines the required and optional attributes for the listing. Walmart's taxonomy is organized hierarchically, and sellers should select the most specific category available. Correct categorization ensures products appear in relevant search results and browse pages, and determines which attribute fields are required in the spec file.
Home > Kitchen & Dining > Kitchen Appliances > Stand MixersAccurate shipping weight is required for all listings and is used to calculate shipping costs for both seller-fulfilled and WFS orders. The weight should include the product and all packaging materials. Inaccurate weights can lead to unexpected shipping cost adjustments and may negatively impact seller performance metrics.
26.4Every product listing requires a valid Walmart Product Tax Code to ensure correct sales tax calculation. Walmart provides a Product Tax Code lookup tool in Seller Center. Using an incorrect tax code can result in overcharging or undercharging customers for sales tax, which may lead to compliance issues and customer complaints.
2038710 (Small Kitchen Appliances)Variant grouping allows related products (different colors, sizes, or counts) to be displayed together on a single product detail page. All variants must share the same Variant Group ID and have consistent primary attribute values. Each variant requires its own unique UPC, SKU, images, and pricing. Walmart supports multi-attribute variants (e.g., Size + Color combinations) for applicable product types.
Variant Group ID: KA-PRO-MIXER with variants: Empire Red (SKU-001), Silver (SKU-002), Onyx Black (SKU-003)Rich Media is Walmart's equivalent of Amazon A+ Content, available to brand owners. It allows sellers to create visually enhanced product descriptions with modules including hero images, feature highlights, comparison charts, and video content. Rich Media content can significantly improve conversion rates and reduce return rates by providing customers with more comprehensive product information and a more engaging shopping experience.

Walmart Marketplace supports product data submission through category-specific spec files (Excel format) and the Walmart Marketplace API (JSON). Spec files can be downloaded from Seller Center and contain all required and optional attributes for each product type. The spec files include built-in validation rules that flag errors before submission. For automated integrations, the Walmart Marketplace API provides RESTful endpoints for item setup, inventory management, pricing updates, and order processing. Walmart also supports integration through certified solution providers and channel management platforms.
Walmart's Product Type Taxonomy organizes all products on the marketplace into a hierarchical category structure. Each product type has its own set of required and optional attributes defined in the category-specific spec file. Sellers must select the most specific product type available to ensure their listings appear in the correct browse and search results. Walmart periodically updates its taxonomy to add new categories and refine attribute requirements. Some categories, such as supplements, alcohol, and certain health products, are restricted and require additional approval before sellers can list products.
Detailed requirements for product titles, descriptions, images, and pricing
Avoid these common issues that cause product listings to be rejected or suppressed
Price parity violation detected (product priced higher than on other retail sites)
Review your product pricing across all sales channels and ensure the total price (item + shipping) on Walmart is competitive with other major retailers. Use a repricing tool to automate price monitoring and adjustments. Consider offering free shipping by incorporating shipping costs into the item price to maintain a competitive total price.
Invalid or unverified product identifier (UPC/GTIN)
Verify that your product identifier is valid and registered in the GS1 database at gepir.gs1.org. Purchase genuine UPCs directly from GS1 (gs1.org). Do not use UPCs purchased from third-party resellers, as Walmart validates barcodes against the GS1 database and will reject unregistered or mismatched identifiers.
Product images do not meet quality standards (low resolution, non-white background, text overlays)
Re-shoot or edit images to meet Walmart's requirements: minimum 1000x1000 pixels (2000x2000 recommended), solid white background for main image, no text overlays or watermarks, and product filling at least 85% of the frame. Ensure images are in JPEG or PNG format and under 5 MB each.
Missing required category attributes in the product spec file
Download the latest category-specific spec file from Seller Center and review all required fields for your product type. Ensure every required attribute is populated with accurate, properly formatted data. Common missing attributes include product dimensions, material, color, pattern, and product tax code.
Product title contains promotional language, special characters, or exceeds character limits
Remove all promotional phrases (Free Shipping, Best Seller, Sale, #1), special characters, HTML tags, and all-caps words from the title. Ensure the title follows Walmart's formula: Brand + Defining Quality + Item Name + Pack Count + Size/Color. Keep the total length under 200 characters with the most important information in the first 50-75 characters.
Shelf description or key features are missing, empty, or improperly formatted
Add a comprehensive shelf description using HTML formatting (paragraphs, unordered lists, bold text) up to 4,000 characters. Add a short description with 3-10 bullet points in an HTML unordered list format. Both fields are required for publishing. Ensure descriptions provide genuine product information and do not contain placeholder text.
Duplicate listing detected (product already exists in Walmart's catalog under a different seller)
Search Walmart's catalog for your product using the UPC or product name. If an existing listing matches your product, use the 'Sell an Existing Item' option in Seller Center to add your offer to the existing product page rather than creating a duplicate listing. Duplicate listings will be automatically merged or removed by Walmart.
Product listed in a restricted or prohibited category without required approvals
Check Walmart's Prohibited Products Policy and the restricted categories list in Seller Center before listing. Some categories (e.g., supplements, over-the-counter medications, alcohol, certain electronics) require additional approval or compliance documentation. Submit the required paperwork through your Seller Center account and wait for approval before re-listing.
Best practices to improve your product listing performance and visibility
Walmart's Listing Quality Score directly impacts search ranking and visibility. Focus on the four pillars: Content Quality (detailed titles, descriptions, and attributes), Discoverability (relevant keywords and accurate categorization), Offer Quality (competitive pricing and fast shipping), and Ratings & Reviews. Monitor your Listing Quality Score dashboard in Seller Center and prioritize improvements on items scoring below 80%. A score above 90% typically correlates with significantly better organic placement in search results.
Products fulfilled through WFS receive the 'Fulfilled by Walmart' badge, qualify for Walmart+ free shipping benefits, and gain significant advantages in Buy Box competition and search ranking. WFS handles storage, picking, packing, shipping, and customer returns. The program offers competitive fulfillment fees based on product weight and dimensions. WFS items also qualify for Two-Day and Next-Day delivery, which are major conversion drivers on the platform.
Walmart's search algorithm evaluates keywords in the product title, key features, shelf description, and backend attributes. Place your most important keywords in the title (first 50 characters are critical), then reinforce them naturally throughout the key features and shelf description. Use Walmart's Search Insights tool to identify high-volume search terms in your category. Unlike Amazon, Walmart does not have a separate backend keyword field, so all keyword optimization must be done within visible product content.
When multiple sellers offer the same product, Walmart's Buy Box algorithm determines which seller's offer is displayed prominently. Key factors include total price (item + shipping), fulfillment speed (WFS and two-day delivery preferred), seller performance metrics (on-time delivery, order defect rate), and inventory availability. Ensure your pricing is competitive, offer fast and reliable shipping, and maintain excellent seller metrics to maximize your Buy Box win rate.
Rich Media allows sellers to create enhanced product descriptions with visual modules including hero banners, feature highlights with images, product comparison charts, and embedded videos. Products with Rich Media content typically see 20-30% higher conversion rates compared to listings with standard text-only descriptions. Apply Rich Media to your top-performing products first and gradually expand to your full catalog. Content can be created through Walmart's Rich Media tool in Seller Center or through approved content syndication providers.
Walmart Connect offers Sponsored Products, Sponsored Brands, and Display advertising to drive targeted traffic to your listings. Sponsored Products appear in search results and on product detail pages, providing high-intent visibility. Start with automatic campaigns to discover converting keywords, then create manual campaigns targeting your best performers. Walmart's advertising platform also offers Walmart DSP for off-site programmatic display advertising that retargets shoppers across the web.
Customer reviews are a critical ranking factor on Walmart. Use Walmart's Review Accelerator program to generate initial reviews for new products through incentivized sampling. Respond to negative reviews professionally and address the underlying issues. Monitor return reasons and customer questions to identify opportunities for listing improvements. Products with more reviews and higher ratings consistently rank better in search results and convert at higher rates.
Walmart runs several major promotional events throughout the year, including Rollbacks, Flash Deals, Walmart+ Week, Holiday Deals, and seasonal sales. Participating in these events can significantly boost visibility and sales volume. Set up promotional pricing through Seller Center well in advance of key shopping periods. Products with competitive promotional pricing and adequate inventory during these events often see lasting improvements in organic search ranking due to the sales velocity boost.
Step-by-step guide to getting your products live on this marketplace
Visit marketplace.walmart.com and submit your seller application with your US Business Tax ID, W-9 or W-8 form, US business address, EIN verification letter, and product catalog details.

Familiarize yourself with the Seller Center dashboard, Listing Quality tools, and performance metrics.
Download the category-specific spec file from Seller Center under Items & Inventory > Add Items > Add Items in Bulk. Review all required and optional attributes for your product type and map your product data to Walmart's field names and format requirements. Ensure every product has a valid GS1-registered UPC or GTIN, high-quality images meeting Walmart's specifications, a keyword-optimized title following the Brand + Defining Quality + Item Name formula, and complete shelf and short descriptions in HTML format.
Upload your completed spec file through Seller Center or use the Walmart Marketplace API for automated product data submission. After upload, check the feed status dashboard for any processing errors or warnings. Common issues include invalid UPCs, missing required attributes, image quality violations, and pricing policy flags. Address all errors and resubmit until your items achieve a 'Published' status.
