Amazon and Walmart Marketplace are often treated as the same kind of channel. They are not. The differences in search behaviour, listing signals and advertising shape the right order to expand and how much effort each channel takes.

Where the two marketplaces actually differ
Both are search-led US marketplaces, and both reward complete, accurate listings. The difference is in the signals that decide whether a product is shown and bought.
| Dimension | Amazon | Walmart Marketplace |
|---|---|---|
| Primary discovery | Keyword search with strong relevance and conversion signals | Search plus a strong emphasis on offer competitiveness and item quality |
| Content signals | Title, bullets, backend terms, A+ content, reviews | Listing quality score, rich attributes, clear specs |
| Price pressure | High; competitors, coupons and deals are visible | Very high; Walmart is known for demanding competitive pricing |
| Advertising | Amazon Ads (Sponsored Products/Brands/Display) | Walmart Connect (search and related placements) |
| Fulfilment | FBA or FBM | WFS or seller-fulfilled |
| Competition | Deep, mature and often expensive | Smaller, but growing fast |
Because Walmart is less saturated, the same catalogue can sometimes gain visibility more cheaply there — but only if the offer and listing quality are genuinely strong, since Walmart leans hard on both.
Which to prioritise first
If you already sell on Amazon, the practical question is whether Walmart is a lower-cost incremental channel for the same products. Before committing, ask:
- Is your pricing competitive enough for Walmart’s comparison behaviour?
- Can the product be fulfilled to Walmart’s service expectations?
- Are your listings accurate and complete, or will they need real rework?
- Do you have the operational capacity for a second marketplace’s inventory and returns?
If you are starting fresh, Amazon usually offers the larger and more mature demand first, while Walmart can be a faster, less crowded second channel — but the right order depends on your category, price and operations, not on a universal rule.
What each channel demands
- Amazon: rigorous listing optimisation, reviews, A+ content, and active advertising management to control ACOS against margin. See listing optimization and Amazon PPC management.
- Walmart: catalog completeness and attributes, listing quality, and Walmart Connect at a competitive price. See Walmart Marketplace services and Walmart PPC management.
Preparing for both
- Make pricing competitive for each channel’s comparison behaviour.
- Build complete, accurate listings with all attributes and specs — not Amazon copy pasted across.
- Define a margin-anchored advertising target before you spend.
- Plan inventory and returns for two channels, not one.
- Measure each channel’s true margin, not just revenue.
Frequently asked questions
Can I use the same listings on Amazon and Walmart?
You can reuse the product data, but not unchanged. Walmart rewards complete attributes and its own listing quality signals, and copy-pasted Amazon bullets usually leave those fields thin. Treat each channel’s listing as its own optimisation job that shares a source of truth for specs and imagery.
Is Walmart easier to sell on than Amazon?
It is often less crowded, which can mean cheaper visibility, but it is not easier — Walmart applies its own scrutiny to pricing and listing quality, and fulfillment expectations are real. “Less competition” is an opportunity, not a shortcut.
Which should an established brand expand to first?
Generally the channel where your existing catalogue, pricing and operations can compete most credibly. For many brands that is Amazon first for scale, then Walmart for lower-cost incremental growth. EcomGuru reviews this per brand in the free growth audit.
