Navigating Listing Rules on Amazon, Walmart, and eBay

A Multichannel Seller’s Guide to Staying Compliant and Competitive

Listing your products across Amazon, Walmart Marketplace, and eBay is one of the most powerful ways to scale your ecommerce business. But each platform has its own strict—and often evolving—rules that dictate what you can and can’t list, how your listings must be structured, and what content is allowed.

Failing to follow listing rules can result in suppressed products, suspended accounts, or even permanent bans.

This guide walks through the key listing requirements for each platform, what to avoid, and how to manage multichannel compliance efficiently.

Why Listing Rules Matter More Than Ever

With increased regulation, competitive pressures, and AI-driven enforcement, marketplaces are stricter than ever about:

  • Listing duplication
  • Image and content compliance
  • Pricing violations
  • Trademark/copyright infringement
  • Shipping and inventory accuracy

If you’re selling on multiple marketplaces, you must tailor listings per platform or risk penalties.

Amazon Listing Rules Overview

Amazon enforces very specific rules for all aspects of product listings, especially in gated or high-risk categories like jewelry, supplements, and electronics.

Key Requirements:

  • No promotional content in titles (e.g., “Best Seller,” “Free Shipping”)
  • Product titles must follow structure: Brand + Product Type + Key Attributes (size, color, quantity)
  • No HTML in bullet points or descriptions
  • Use only white background product images (1000×1000+)
  • Must match brand name and GTIN (UPC/ASIN) correctly

Violations to Avoid:

  • Using competitor brand names (can trigger IP complaints)
  • Listing generic products as branded
  • Listing in incorrect categories
  • Exceeding character limits (200 for title, 500 per bullet point)

Tools for Compliance:

  • Listing Quality Dashboard (Seller Central)
  • Brand Registry for authorized brand control
  • EcomBiz.AI’s Amazon listing templates ensure structure alignment and auto-flag errors

Walmart Marketplace Listing Rules Overview

Walmart has stricter content and performance guidelines than many sellers expect. It uses content scoring algorithms to auto-grade listings.

Key Requirements:

  • Titles limited to max 75 characters
  • No promotional phrases (e.g., “New!”, “Limited Edition”)
  • Requires primary and additional images (no logos or watermarks)
  • Attributes like color, size, material, brand are mandatory in many categories
  • Product IDs (GTINs) must be unique and valid (no duplicates allowed)

Common Triggers for Delisting:

  • Duplicate content from Amazon
  • Mismatched images or poor resolution
  • Incorrect categorization
  • Missing fulfillment lag time or inventory node

Pro Tip:

Walmart’s algorithm prioritizes listings with high-quality attributes and rich content—not just title optimization.

Use platforms like EcomBiz.AI to auto-populate and enrich Walmart-required fields.

eBay Listing Rules Overview

eBay gives more flexibility than Amazon or Walmart but still has clear guidelines to avoid listing takedowns.

Key Requirements:

  • Titles limited to 80 characters, use relevant keywords without stuffing
  • Up to 12 gallery images allowed; primary image must be of the actual product
  • HTML allowed in descriptions (limited usage recommended)
  • Include item specifics: brand, size, condition, style, etc.

Prohibited Practices:

  • Selling prohibited or counterfeit items
  • Using misleading terms like “like new” for used items
  • Listing in wrong categories or with vague item specifics
  • Repeated listing of out-of-stock products (can lower search visibility)

eBay-Specific Tips:

  • Use item condition notes accurately
  • eBay rewards sellers who offer free shipping and 30-day returns
  • Use structured data fields to boost discoverability

How to Manage Listing Rule Compliance Across Platforms

Staying compliant across Amazon, Walmart, and eBay requires platform-specific listing generation and automation.

Manual Method (Not Recommended):

  • Create separate listings in each seller portal
  • Maintain platform-specific spreadsheets for compliance
  • Constantly monitor changes to listing policies

Recommended Approach:

Use a centralized platform like EcomBiz.AI to:

✅ Build platform-compliant titles, descriptions, and metadata
✅ Auto-map attributes and required fields
✅ Detect and flag missing GTINs, banned phrases, or invalid categories
✅ Monitor listing health scores across all channels
✅ Ensure real-time syncing of changes to content or inventory

Navigating listing rules on Amazon, Walmart, and eBay doesn’t have to be a full-time job—but it does require a smart approach.
