How to Advertise on Walmart Marketplace: A 2025 Guide

published on 26 April 2025

Walmart Marketplace has rapidly evolved into one of the premier platforms for online retail, offering sellers an expansive customer base and increased brand visibility. 

In 2025, Walmart Marketplace is projected to generate $9 billion in gross merchandise volume (GMV), reflecting its rapid growth and becoming a vital channel for e-commerce businesses to tap into Walmart's massive foot traffic both online and in-store. 

But with more sellers entering the arena, competition is fierce. 

To stand out, effective advertising strategies are essential. 

This guide explores how to navigate and optimize Walmart Marketplace advertising in 2025, from understanding ad formats to measuring ROI and refining your campaigns.

Different Types of Advertising Options on Walmart Marketplace

Executives evaluating Walmart Marketplace should understand the distinct ad products available, each with a different role in the conversion funnel and cost structure:

  1. Sponsored Products: Performance-based (PPC) ads that deliver high-intent traffic by appearing in search results and product pages. For every $1 invested, brands can achieve an average ROAS between $3โ€“$5, depending on category and seasonality.
  2. Sponsored Brands: Upper-to-mid funnel brand-building placements offering custom creative and cross-product visibility. Ideal for Customers looking to drive category share and brand recall.
  3. Display Ads via Walmart Connect: Deliver visual impressions across Walmart.com and partner properties. With Walmart's first-party data, brands can target based on 5,000+ shopper segments.
  4. Video Ads: These are showing a 60% higher engagement rate than static formats. Used effectively, they influence consideration and lift brand affinity at scale.
  5. In-store DSP (Demand Side Platform): Unites digital advertising with brick-and-mortar retail. Brands can target customers by store location, purchase behavior, or real-time in-store presence, boosting omnichannel conversions.
  6. Social + Influencer Integrations: Tapping Walmartโ€™s influencer network, livestreams, and social placements adds authentic voices to your digital marketing stackโ€”often at a lower CAC than traditional channels.

Setting Up Your Advertising Campaign

From a Customer perspective, campaign setup must align with quarterly revenue targets, marketing mix models, and ROI thresholds. Hereโ€™s how to structure a Walmart ad campaign for bottom-line impact:

  1. Platform Onboarding: Through Walmart Connect, ensure integration of seller and ad accounts. For enterprise brands, API or platform-based campaign management (e.g., via Pacvue, Skai) enables real-time visibility and scalability.
  2. Objective Mapping: Align campaigns to business KPIsโ€”e.g., incremental sales lift, customer acquisition cost (CAC), or ROAS. For example, a 20% increase in Sponsored Product spend may yield a 15% lift in sell-through if properly optimized.
  3. Ad Format Selection: Use Sponsored Products for short-term sales goals, and layer Sponsored Brands or Display Ads for category growth and retention.
  4. Strategic Budgeting: Allocate budgets by product margin, inventory turn rate, and promotional calendar. Walmartโ€™s auction dynamics favor consistent daily spending to stabilize CPCs and drive cost-efficiency.
  5. SKU Targeting: Prioritize SKUs with high conversion rates, healthy stock, and positive reviews. Advertised items with these traits tend to produce 20โ€“40% better ROAS.
  6. Asset Development: Invest in premium creative, especially for display and video. Brands with elevated visuals see 2x higher CTR and greater downstream sales.
  7. Launch & Iterate: Initial results should inform campaign rules and bid logic. Automated rules help protect margin thresholds and improve operational oversight.
  8. Listing Synchronization: Listings influence ad relevance. Enhanced content drives a measurable uplift in quality scores and CTR.

Targeting and Optimization Strategies

Optimizing for performance is where Walmart Marketplace advertising can deliver material gains in customer acquisition efficiency and media ROI:

  1. Keyword Strategy: Use high-conversion keywords aligned to Walmart's buyer behavior. Keyword refinement and negative keywording can improve ACOS by up to 25%.
  2. Campaign Segmentation: Separate branded, generic, and competitor keywords into different campaigns. This provides clearer attribution and better budget distribution.
  3. Smart Bidding: Monitor CPC, CTR, and conversion metrics daily. For example, increasing bids by 15% on top-converting SKUs during peak hours can yield 10โ€“20% higher revenue.
  4. Audience Targeting: Leverage Walmartโ€™s shopper data to segment by demographic, household, or past behavior. Precision targeting lowers CAC and increases new-to-brand penetration.
  5. Regional & Time-Based Targeting: Adjust bids by region or time-of-day. Walmart DSP enables smart scheduling to hit peak windows for in-market consumers.
  6. A/B Creative Testing: Brands conducting multivariate creative tests typically improve ad performance by 18โ€“25% over static campaigns.
  7. AI and Predictive Optimization: Walmartโ€™s tools offer machine-learning insights. These can automate underperformer pausing, bid increases, and budget reallocation.

Measuring Success and Analytics

Customers demand clear proof of performance. Walmartโ€™s ecosystem provides granular, real-time analytics to support strategic decision-making:

1. Performance KPIs:

  • ROAS: Return on Ad Spend is the ultimate measure of financial impact.
  • ACOS: Critical for ensuring campaign profitability.
  • TACoS: Offers insight into advertisingโ€™s influence on total business revenue.
  • Conversion Rate & Click-Through Rate: Reveal funnel efficiency.

2. Walmart Ad Center + Third-Party Tools: Use Walmart Ad Center for operational metrics, and layer in analytics platforms (like Pacvue or Perpetua) to benchmark, forecast, and optimize holistically.

3. Attribution Reporting: Multi-touch attribution gives visibility into where ads drive value along the path to purchase. For Customers, this supports budgeting across awareness vs. conversion-driving formats.

4. Revenue Lift Modeling: Run pre/post campaign tests to isolate incremental lift. Many Walmart advertisers see 15โ€“30% overall sales lift when implementing full-funnel strategies.

5. APIs and Dashboards: Use custom dashboards to consolidate campaign metrics with inventory, pricing, and customer data. This enables high-level trend spotting and executive reporting.

Best Practices for Advertising on Walmart Marketplace

To deliver shareholder value and scalable performance, consider these executive-level best practices:

  1. Inventory & Supply Chain Coordination: Ads without stock = wasted spend. Automate alerts for low inventory on advertised SKUs.
  2. Business Cycle Alignment: Campaigns should reflect quarterly sales goals, product launches, and peak retail moments.
  3. Optimize for Margin, Not Just Revenue: Avoid low-margin SKUs unless they support high-LTV acquisition or strategic goals.
  4. Invest in Data Infrastructure: API access, attribution modeling, and SKU-level insights are essential for optimizing complex ad programs.
  5. Cross-Channel Synergy: Align Walmart ads with Amazon, Meta, and DTC channels. Unified measurement maximizes total media efficiency.
  6. Leverage Automation with Guardrails: Use auto-bidding and AI, but set ROAS thresholds and caps to maintain profitability.
  7. WFS Advantage: Fulfilled by Walmart (WFS) SKUs typically earn better placements, conversion, and Buy Box winsโ€”improving every ad dollarโ€™s impact.
  8. Customer-Led Ad Strategy: Ensure that your campaign strategy supports best-in-class customer experience (e.g., speed, price, reliability). Happy customers drive repeat revenue.
  9. Executive Scorecarding: Track a high-level dashboard of KPIsโ€”ROAS, total media spend, attributed revenue, TACoS, and marginโ€”monthly or weekly.
