Selling on large marketplaces requires more than great products. Visibility is the deciding factor between stagnant listings and consistent revenue. On platforms like Amazon and Walmart, advertising plays a central role in gaining that visibility.
Many sellers entering Walmart Marketplace assume the advertising system works exactly like Amazon PPC. That assumption leads to wasted budget and slow growth. While both platforms use pay-per-click models, the algorithms, competition levels, and campaign mechanics differ significantly.

This guide provides a detailed comparison between Walmart advertising and Amazon PPC. It explains how each platform structures ads, how bidding works, how the algorithms prioritize listings, and what strategies produce measurable results for sellers.
If you sell on both marketplaces – or plan to – understanding these differences allows you to allocate budget more effectively and scale profitably.
The Evolution of Marketplace Advertising
Marketplace advertising has evolved from a simple sponsored listing model into a performance-driven retail media system.
Amazon launched its internal advertising platform in 2012 and has since built one of the largest retail media networks in the world. Amazon ads now influence product discovery across search results, product pages, and external websites.
Walmart entered the retail media space later, formally building its ad ecosystem under Walmart Connect. Although newer, Walmart’s advertising network has grown quickly as more brands look for alternatives to the intense competition on Amazon.
For sellers, this means two very different advertising environments:
- Amazon: mature, highly competitive, data-dense
- Walmart: newer, less saturated, but rapidly evolving
Understanding these structural differences is essential before comparing specific campaign types.
Advertising Models: Amazon PPC vs Walmart Advertising
Both platforms operate primarily on a pay-per-click (PPC) model. Sellers pay when a shopper clicks an ad placement.
However, the ad ecosystems differ in complexity.
Amazon Advertising Structure
Amazon offers several ad types inside its marketplace:
Sponsored Products
- Keyword-targeted product ads
- Appear in search results and product pages
- Most commonly used campaign type
Sponsored Brands
- Banner-style ads featuring brand logo and multiple products
- Appear at top of search results
Sponsored Display
- Retargeting and audience-based advertising
- Appears both on and off Amazon
These formats create a multi-layered advertising system with several audience targeting methods.
Walmart Advertising Structure
Walmart focuses primarily on a simplified PPC system.
Key formats include:
Sponsored Products
- Keyword and automatic targeting
- Appear in search results and product pages
If you’re learning the platform for the first time, it helps to review how Sponsored Products campaigns work on Walmart Marketplace before building your first ad structure.
Sponsored Brands (Beta in many accounts)
- Banner placements for brands
- Less widely adopted compared to Amazon
Display Advertising via Walmart Connect
- Audience targeting and retargeting options
- Often used by larger brands rather than individual sellers
For most marketplace sellers, Walmart advertising means managing Sponsored Products campaigns.
Marketplace Search Algorithms and Ad Performance
Advertising effectiveness depends heavily on the search algorithm behind the marketplace.
Amazon’s Advertising and Ranking System
The ranking system on Amazon revolves around its internal search algorithm commonly known as A9 (now evolving toward A10-style ranking logic).
Ad performance and organic ranking influence each other. When an ad campaign generates conversions:
- organic rank improves
- product visibility increases
- advertising efficiency rises over time
Key ranking signals include:
- conversion rate
- click-through rate
- historical sales velocity
- review quality and volume
- listing relevance
Advertising essentially accelerates ranking signals.
Walmart’s Advertising and Ranking System
Walmart uses a search algorithm that emphasizes operational performance more heavily than Amazon.
Important ranking signals include price competitiveness, fulfillment speed, on-time shipping rate, inventory stability, and conversion rate. Sellers who want to improve visibility should also understand how Walmart’s search ranking system evaluates listings, not just focus on ad campaigns.
Advertising can increase traffic, but operational metrics influence visibility more strongly than ads alone.
A product with weak fulfillment metrics will struggle to scale even with aggressive ad spend.
Cost Per Click: Walmart vs Amazon
One of the most noticeable differences between the platforms is advertising cost.
Amazon CPC Environment
Because millions of sellers compete on Amazon, CPC bids have increased significantly across most categories.
Typical ranges:
- competitive niches: $1.50 – $4.00+
- mid-tier categories: $0.70 – $1.50
- low competition categories: $0.30 – $0.70
Highly competitive niches like supplements, electronics, or home goods often see CPCs well above $3.
The mature ecosystem drives costs upward.
Walmart CPC Environment
On Walmart, CPC remains significantly lower due to fewer advertisers.
Typical ranges:
- competitive categories: $0.60 – $1.20
- mid-tier categories: $0.30 – $0.70
- low competition niches: $0.15 – $0.40
This difference creates an opportunity for sellers who already understand PPC optimization.
Lower CPC allows faster testing and cheaper traffic acquisition.
Keyword Targeting Differences
Although both systems support keyword targeting, the behavior of search traffic differs.
Amazon Keyword Dynamics
Search behavior on Amazon tends to be highly specific and purchase-focused.
Examples:
- ergonomic office chair lumbar support
- wireless gaming mouse RGB
Long-tail keywords dominate the ecosystem. Amazon’s algorithm understands purchase intent deeply.
As a result, successful PPC campaigns rely on:
- detailed keyword research
- long-tail segmentation
- bid optimization by search term
Walmart Keyword Behavior
Search behavior on Walmart often resembles general retail browsing.
Queries tend to be broader:
- “office chair”
- “gaming mouse”
- “kitchen blender”
Broad keywords generate a large share of traffic.
Because of this pattern, Walmart campaigns often rely more heavily on:
- automatic targeting
- broader keyword coverage
- listing optimization to drive conversion
Competition Levels Across Platforms
Competition strongly affects advertising strategy.
Amazon Marketplace Competition
Amazon hosts millions of sellers and hundreds of millions of products.
In most established categories:
- dozens of sellers bid on the same keywords
- CPC prices escalate quickly
- ranking improvements require sustained advertising
Breaking into the top search results often requires both:
- aggressive PPC spending
- strong external traffic
Walmart Marketplace Competition
Walmart still has significantly fewer sellers.
Although the marketplace is growing, many niches remain under-advertised. Sellers researching product opportunities should also review which categories currently perform well on Walmart Marketplace before launching new listings.
Advantages include:
- lower bid pressure
- fewer sophisticated PPC competitors
- faster ranking improvements
However, the gap is shrinking as more sellers expand into Walmart.
Conversion Rate Differences
Traffic quality plays a major role in advertising ROI.
Amazon Conversion Behavior
Customers browsing Amazon usually arrive with a clear buying intention.
This produces:
- higher conversion rates
- strong PPC ROI potential
- more predictable scaling
Experienced sellers frequently see conversion rates between 10% and 20% depending on category.
Walmart Conversion Behavior
On Walmart, shoppers include both online buyers and traditional retail customers transitioning from physical stores.
Conversion rates tend to be slightly lower.
However, strong pricing and fulfillment performance can dramatically increase conversions.
Walmart shoppers are particularly sensitive to:
- price
- delivery speed
- trust signals
Campaign Management and Optimization
Advertising management differs significantly between the platforms.
Amazon PPC Optimization
Advanced Amazon PPC campaigns involve:
- campaign segmentation
- keyword harvesting
- negative keyword filtering
- bid automation
- placement adjustments
Many sellers run dozens or even hundreds of campaigns to control traffic precisely.
The complexity reflects Amazon’s mature advertising infrastructure.
Walmart Advertising Optimization
Campaign management on Walmart is simpler but still requires strategic structure.
Effective Walmart campaigns usually include:
- automatic discovery campaigns
- manual keyword campaigns
- product targeting campaigns
- bid adjustments based on conversion data
New sellers who are still learning campaign structure should start with a practical advertising framework designed for Walmart sellers.
Because competition is lower, optimization cycles move faster.
Attribution and Analytics
Data access determines how precisely sellers can optimize campaigns.
Amazon Advertising Data
Amazon offers extensive analytics including:
- search term reports
- placement performance
- conversion tracking
- attribution modeling
Advanced sellers often combine this data with external tools to manage large ad portfolios.
Walmart Advertising Data
Walmart provides fewer analytics tools but continues to expand reporting features.
Available insights include:
- keyword performance
- click-through rate
- conversion data
- attributed sales
While simpler, the reporting still supports effective optimization for most sellers.
Real Example: Launch Strategy on Both Platforms
Consider a mid-priced kitchen product launching on both marketplaces.
Amazon strategy
- Launch with automatic and manual campaigns
- Target 30 – 50 long-tail keywords
- Increase bids on converting search terms
- Build review velocity to improve organic ranking
Walmart strategy
- Launch with automatic campaigns for discovery
- Target 10 – 20 high-volume keywords
- Focus on competitive pricing and fast fulfillment
- Scale budget gradually as conversion data accumulates
The difference reflects how each marketplace processes traffic and competition.
Advantages of Walmart Advertising
Selling through Walmart offers several advantages for advertisers.
Lower advertising costs
CPC remains significantly lower in most categories.
Less competition
Many sellers still focus exclusively on Amazon.
Faster ranking gains
Products can climb search results more quickly when conversion signals are strong.
For experienced PPC sellers, Walmart often becomes a profitable secondary marketplace.
Advantages of Amazon PPC
Amazon still provides the most advanced marketplace advertising system.
Advantages include:
Massive customer base
Amazon receives billions of product searches each month.
Advanced ad formats
Sponsored Brands and Sponsored Display create more marketing options.
Sophisticated analytics
Detailed reports support complex optimization strategies.
For high-volume brands, Amazon remains the primary advertising platform.
When Sellers Should Focus on Walmart Advertising
Walmart advertising makes strategic sense when:
- Amazon CPC costs become unprofitable
- the product category has limited competition on Walmart
- fulfillment and pricing advantages exist
- the brand wants diversified traffic sources
Many successful sellers now treat Walmart as a second growth channel after Amazon.
Final Thoughts
Both marketplaces rely on PPC advertising, but their ecosystems differ dramatically.
Amazon offers a mature, highly competitive advertising system with advanced targeting and massive traffic.
Walmart provides a newer environment with lower CPC, less competition, and growing demand.
