Building a Multi-Channel Strategy: Amazon, Walmart, eBay & Beyond

Introduction: Why Multi-Channel Is No Longer Optional  

The global eCommerce landscape has fundamentally changed. Relying on a single marketplace even one as powerful as Amazon – is no longer a sustainable long-term strategy for brands, manufacturers & sellers who want predictable growth, risk mitigation & brand control.

Policy changes, account suspensions, Buy Box volatility, rising advertising costs & increasing competition have made it clear: successful brands in 2025 & beyond are multi-channel by design.

At RootAMZ, we work with vendors & sellers who want more than survival – they want structured, scalable & profitable growth across Amazon, Walmart, eBay & emerging marketplaces. This guide explains how to build a winning multi-channel strategy, the common challenges sellers face & how RootAMZ acts as a complete solution partner at every stage.

What Is a True Multi-Channel eCommerce Strategy?  

A multi-channel strategy is not simply listing the same product on multiple platforms. A true strategy aligns:

• Marketplace-specific algorithms
• Platform compliance & policies
• Pricing parity & profitability
• Inventory & fulfilment models
• Advertising & brand visibility
• Centralized operations & reporting

Without this alignment, sellers experience margin erosion, operational chaos & performance suppression.

RootAMZ builds multi-channel ecosystems – not disconnected listings.

Core Challenges Sellers Face When Expanding Beyond One Marketplace  

Before discussing solutions, it’s critical to understand the most common problems vendors & sellers encounter when attempting multi-channel expansion.

1. Platform Policy Conflicts & Compliance Issues  

Each marketplace has its own policies:

• Amazon enforces strict performance metrics, category restrictions & brand registry rules
• Walmart emphasises pricing parity, on-time shipment & content quality
• eBay prioritises seller reputation, item specifics & fulfilment speed

Many sellers unknowingly violate policies by using identical content, incorrect categories or non-compliant pricing structures.

RootAMZ Solution: We deploy platform specific compliance frameworks, ensuring listings, categories & documentation align with each marketplace’s rules reducing risk of suppression or de listing.

2. Listing Optimisation That Doesn’t Translate Across Platforms  

What converts on Amazon does not automatically convert on Walmart or eBay.

• Amazon relies heavily on keywords, backend search terms & A+ Content
• Walmart rewards structured attributes, content scores & competitive pricing
• eBay emphasises item specifics, long-tail keywords & buyer trust signals

Copy-pasting listings results in poor visibility & low conversion rates.

RootAMZ Solution: Our catalogue specialists create marketplace-native listings:

• Amazon SEO + conversion-focused copy
• Walmart-optimized attributes & content scoring
• eBay item-specific-rich, trust-driven descriptions

Every listing is optimised for search, compliance & conversion – platform by platform.

Amazon: The Foundation of Most Multi-Channel Strategies  

For many sellers, Amazon remains the primary revenue driver & rightly so.

However, Amazon is also the highest risk platform when mismanaged.

Common Amazon Challenges  

• Account health violations
• Listing suppressions
• Buy Box loss
• Rising PPC costs
• Inventory performance index (IPI) issues
• Brand hijacking

RootAMZ Amazon Expertise:

With ex Amazon Account Health, Catalogue, Seller Support & Vendor Central specialists, RootAMZ provides:

• End-to-end Seller Central & Vendor Central management
• Account Health monitoring & appeal handling
• Buy Box strategy & pricing intelligence
• A+ Content, Brand Store & Brand Story design
• PPC strategy aligned with profitability, not just ACOS

Amazon becomes the control center, not a constant risk.

Walmart Marketplace: The Fastest-Growing Amazon Alternative  

Walmart Marketplace is no longer a “secondary channel.” It is a strategic growth engine – especially for brands that execute professionally.

Common Walmart Seller Issues  

• Listing quality score problems
• Pricing parity suppression
• Fulfilment & shipping performance penalties
• Difficulty scaling ads profitably

RootAMZ Walmart Strategy:

We treat Walmart as a distinct ecosystem, not an Amazon clone.

Our services include:

• Walmart seller onboarding & category approvals
• Attribute-level listing optimisation
• Walmart Fulfilment Services (WFS) strategy
• Pricing parity & Buy Box alignment
• Walmart Ads setup & optimization

RootAMZ helps sellers unlock Walmart’s algorithmic trust – leading to stronger visibility & Buy Box consistency.

eBay: High-Margin, Brand-Controlled Marketplace When Done Right  

eBay remains one of the most underestimated marketplaces for brands & manufacturers.

When executed properly, eBay offers:

• Lower advertising dependency
• Strong repeat customer potential
• Higher control over brand messaging

Common eBay Challenges  

• Poor item specifics
• Low visibility in search results
• Inconsistent brand presentation

RootAMZ eBay Optimisation:

Our team focuses on:

• Deep keyword research & item-specific mapping
• Storefront design & brand consistency
• Reputation management & performance metrics
• Scalable listing frameworks for large catalogs

eBay becomes a profit-focused channel, not an afterthought.

Inventory & Fulfilment: The Backbone of Multi-Channel Success

Inventory mismanagement is the fastest way to destroy a multi-channel strategy.

Common problems include:

• Overselling across platforms
• Stock outs on high-performing SKUs
• Excess FBA fees or long-term storage costs

RootAMZ Inventory Strategy:

We design inventory models that balance:

• Amazon FBA
• Walmart WFS
• Seller-Fulfilled & 3PL solutions

Our forecasting approach ensures:

• Platform-specific demand planning
• Reduced storage penalties
• Improved cash flow & sell-through

Pricing & Buy Box Strategy Across Marketplaces  

Pricing inconsistencies are one of the biggest risks in multi-channel selling.

• Amazon penalises higher off-Amazon prices
• Walmart suppresses listings for parity violations
• eBay buyers compare aggressively

RootAMZ Pricing Intelligence:

We implement:

• Centralised pricing rules
• Buy Box-aware automation
• Margin-protected discounting strategies

This ensures compliance without sacrificing profitability.

Advertising & Visibility Across Channels  

Each marketplace has its own advertising ecosystem:

• Amazon PPC (Sponsored Products, Brands, Display)
• Walmart Ads (Search, Browse, Brand Amplifier)
• eBay Promoted Listings

Running ads without a unified strategy leads to wasted spend.

RootAMZ Advertising Framework:

We align:

• Keyword strategy with organic rankings
• Ad budgets with inventory availability
• ROAS targets with real margins

Advertising becomes a growth lever, not a cost center.

Data, Reporting & Decision-Making  

Multi-channel selling generates fragmented data.

Most sellers struggle to answer basic questions:

• Which channel is most profitable?
• Where are we losing margin?
• Which SKUs deserve more investment?

RootAMZ Analytics Approach:

We provide unified reporting across:

• Sales
• Advertising
• Inventory
• Profitability

Decisions are made on data, not assumptions.
