Retail Media Network (RMN)
A retail media network is an advertising platform owned and operated by a retailer (like Amazon or Walmart) that lets brands buy ads shown to shoppers on that retailer's website, app, or in-store. For CMOs, it's a direct channel to reach customers at the moment they're ready to buy—and the retailer owns the data.
Full Explanation
The Problem It Solves
Traditional digital advertising relies on third-party data brokers and platforms you don't control. You buy ads on Google or Facebook, but you're competing with millions of other brands for attention, and you don't know if those ads actually drive sales at a specific retailer. Retail media networks flip this: the retailer controls the ad platform, the customer data, and the sales outcome. You advertise directly where purchase intent is highest.
How It Works in Marketing
When a customer searches for "running shoes" on Amazon, a brand's sponsored product ad can appear at the top of results. That same brand can also bid for placement on the retailer's homepage, in email campaigns, or on competitor product pages. The retailer tracks whether that ad led to a purchase—because the sale happens on their platform.
Think of it like owning a billboard in a store where you can see exactly which customers stop to look and whether they buy.
Real-World Example
A CPG brand selling protein bars can run ads on Walmart's RMN to reach shoppers actively browsing the snack aisle (digitally). Walmart's data shows the brand exactly which demographics clicked, which bought, and which bought competitors instead. The brand pays per click or per sale, not just for impressions.
What This Means for Tool Selection
RMNs are becoming must-have channels in your media mix. Major retailers (Amazon, Walmart, Target, Instacart) all operate their own networks. You'll need:
- Dedicated management tools that integrate with multiple RMNs (not all platforms talk to each other)
- First-party data connectors to match your customer lists to shopper IDs
- Attribution clarity so you can measure RMN ROI separately from other channels
- Workflow automation to manage bids, budgets, and creative across networks without manual overhead
When evaluating AI marketing tools, ask: *Does this integrate with the RMNs where our customers actually shop?*
Why It Matters
Retail media networks are where advertising and commerce converge. Unlike traditional digital ads, RMN placements happen at the moment of purchase intent—when a shopper is already in buying mode. This drives measurable ROI.
- Direct sales attribution: You see exactly which ads led to purchases, eliminating the guesswork of traditional digital marketing
- First-party data advantage: Retailers own shopper behavior data you can't access elsewhere; brands that master RMNs gain competitive edge
- Margin improvement: RMN revenue is growing faster than traditional retail; brands that don't advertise on RMNs lose shelf space and visibility to competitors who do
- Budget efficiency: Cost-per-acquisition on RMNs is often lower than Google or social because intent is pre-qualified
For CMOs, RMNs represent a shift from brand awareness to performance marketing. Your budget allocation needs to reflect this. Retailers are increasingly using RMN revenue to offset margin pressure, which means brands without RMN presence face reduced promotional support and shelf visibility. This is no longer optional—it's table stakes for CPG, beauty, and health brands.

Attribution Modeling
Attribution modeling is the process of assigning credit to different marketing touchpoints that led to a customer conversion. Instead of giving all credit to the last click, it distributes value across the entire customer journey to show which channels and campaigns actually drove results.
Programmatic Advertising
The automated buying and selling of digital ad space using software and algorithms instead of manual negotiations. It lets you target the right person at the right time with minimal human intervention, making ad spending faster and more efficient.
First-Party Data
Information you collect directly from your own customers and website visitors—like email addresses, purchase history, and behavior on your site. It's the most reliable data you own, unlike third-party data bought from brokers or collected by other companies.
Customer Data Platform (CDP)
A CDP is a software system that collects customer data from all your marketing, sales, and service tools into one unified profile. Think of it as a single source of truth about who your customers are, what they've done, and what they're likely to do next—so you can personalize marketing at scale without manual work.
