Most marketplace sellers learn Amazon SEO first, then assume Walmart works the same way. It does not. Both platforms want to show shoppers the most relevant, trustworthy and purchasable product, but they weigh signals differently and give sellers different levers to pull. This guide breaks down Walmart SEO vs. Amazon SEO so you can optimize each listing for the platform it actually lives on.
Amazon SEO leans heavily on sales performance (conversion, sales velocity, and advertising support) layered on top of keyword relevance. Walmart SEO puts more emphasis on listing quality, complete structured data, in-stock reliability, shipping speed, and competitive pricing. Neither platform publishes its full ranking formula, so treat any claim of a “secret algorithm” with caution and rely on official guidance and your own testing.
On Google, a searcher is usually researching. On a marketplace, the searcher is usually ready to buy. That shift in search intent changes everything: the algorithm is optimizing for purchases, so it favors listings that convert, ship fast and stay in stock.
“On a marketplace, SEO is not just about being found. It is about being found and bought.”
Amazon’s search system is commonly called A9 or A10 by the seller community. Amazon does not publish a ranking formula under those names, so use them as shorthand rather than as documented facts. What sellers consistently observe, and what Amazon’s own seller guidance supports, is that ranking blends two things: relevance (do your text and attributes match the query?) and performance (do shoppers click, buy and stay satisfied?).
Walmart Marketplace also blends relevance and performance, but sellers get a more explicit view of listing health. Walmart provides a Listing Quality score in Seller Center that evaluates areas such as content and discoverability, offer competitiveness, ratings and reviews, and post-purchase quality. Walmart periodically updates the details, so confirm the current criteria on Walmart Marketplace and in your Seller Center dashboard.
| Factor | Amazon | Walmart |
|---|---|---|
| Main emphasis | Relevance plus sales performance | Relevance plus listing quality and offer strength |
| Keyword fields | Title, bullets, description, backend search terms | Title, key features, description, structured attributes (varies by category) |
| Visibility into quality | Limited direct scoring; rely on metrics and Brand Analytics | Listing Quality dashboard in Seller Center |
| Pricing pressure | Strong; affects Buy Box | Strong; price competitiveness is closely monitored |
| Fulfillment program | FBA | WFS |
| Advertising | Amazon Ads (Sponsored Products, Brands, Display) | Walmart Connect (Sponsored Search and more) |
| Competition level | Typically more crowded | Often less saturated, varies by category |
Always verify current requirements in Seller Central or Walmart Seller Center, as both platforms update policies regularly.
| Platform | Pros | Cons |
|---|---|---|
| Amazon | Huge shopper base, mature tools, deep ad ecosystem | Crowded categories, rising ad costs, strict policies |
| Walmart | Growing marketplace, clear quality dashboard, opportunity in less saturated niches | Approval process, stricter performance expectations, smaller tool ecosystem |
Brands that sell on several marketplaces gain the most from systemizing this work. Common applications include:
HighDreamsLLC is a Colorado-based AI and digital growth agency. We manage e-commerce across Amazon, Walmart, Etsy and eBay, and build the AI chatbots, voice agents, workflow automation, websites and apps that support those channels. That means your listings, your operations and your customer experience are handled by one team.
Often there is less advertising pressure on Walmart Marketplace, but it is not automatically easier. Walmart puts heavy weight on listing quality, in-stock rates, shipping performance and price competitiveness, so sellers with weak operations struggle on both platforms.
You can reuse your research and core copy, but you should not copy and paste. Walmart uses its own Item Spec, attribute requirements and content rules, and its shoppers search differently. Adapt titles, bullets and attributes to Walmart’s requirements.
Walmart relies on structured attributes and visible content more than a single hidden keyword field. Check the current Item Spec for your category in Seller Center to see which keyword-related attributes are supported.
Yes. Ratings and reviews are part of Walmart’s Listing Quality framework and influence shopper trust and conversion, just as they do on Amazon.
Many brands do, because it diversifies sales channels. The key is to have inventory and operations that can meet both platforms’ performance standards, and a process to keep listings and pricing consistent.
Amazon rewards listings that sell; Walmart rewards listings that are complete, competitive and reliably fulfilled. The best sellers treat them as two related but distinct systems: one research process, two tailored executions. Start with your top products, rebuild each listing to the platform’s rules, and measure what moves.
