Marketplace Channel Guides: Amazon, Walmart, eBay, and Etsy

Every marketplace has its own rules for registration, listing structure, image specs, variations, brand approval, and compliance. Getting any of these wrong means delayed launches, rejected listings, or suppressed products.

The guides here cover the US channels where fashion and lifestyle brands have the most to gain: Amazon, Walmart, eBay, and Etsy. Each guide goes step by step through setup, listing requirements, common rejection reasons, and how to fix them, so your team spends less time troubleshooting and more time selling.

FAQ

What are the image requirements for selling fashion on Amazon, Walmart, and eBay?

Each channel has distinct image standards. Amazon requires a pure white background for main images, minimum 1000px on the longest side, and no watermarks or text overlays. Walmart has similar standards but enforces them through automated review. eBay allows more flexibility but has specific requirements for variations and swatch images. The channel guides here cover every image requirement in detail, including common mistakes that trigger suppression.

How do I get brand approval on Amazon, Walmart, or Etsy?

Brand approval processes differ by channel. Amazon Brand Registry requires a registered trademark and gives access to A+ content, brand stores, and enhanced protection. Walmart's brand approval is tied to the seller application process and product identifier requirements. Etsy does not have a formal brand approval program but has specific policies around handmade, vintage, and licensed goods. The guides here walk through each process with the exact steps and documents required.

What causes marketplace listing rejections and how do I fix them?

The most common causes are non-compliant images, missing or invalid GTINs, incomplete required attributes, prohibited product claims, and category mismatches. Each marketplace has different rejection codes and resolution paths. The channel guides here cover the specific rejection types for Amazon, Walmart, and eBay, with step-by-step fixes for each.

How do I set up product variations correctly on Amazon, Walmart, and eBay?

Variations let you group related products like different sizes or colors under a single listing. Each channel handles variation structure differently. Amazon uses parent-child relationships with variation themes. Walmart uses variant groups. eBay uses multi-variation listings. Setting these up incorrectly fragments your catalog and hurts search visibility. The guides here cover correct variation setup for each channel from scratch.

Should a fashion brand sell on Walmart Marketplace in 2026?

Yes, for most fashion and D2C brands it is worth serious consideration. Walmart Marketplace now attracts over 400 million monthly visits, has no monthly subscription fee, and is significantly less competitive than Amazon across most apparel categories. The application process is selective, which keeps the quality bar high and gives approved sellers stronger organic visibility than they would get launching on Amazon today.
