Stop what you're doing and answer this question: where do you think your customers make their purchase decisions?
If you said "at the shelf," congratulations. You're living in 2005.
Today's purchase decisions happen everywhere BUT the shelf. They happen while doom-scrolling Instagram at 2 AM. They happen during the morning commute on a grocery app. They happen on a smart TV while binge-watching reality shows. And increasingly, they happen inside retail media networks: the walled gardens where retailers have turned themselves into publishers, data brokers, and kingmakers all at once.
Welcome to the $179.5 billion retail media revolution. A world where Walmart isn't just a retailer; it's a media company. Where Kroger knows more about your customers than you do. Where your advertising budget is being held hostage by the very partners you depend on for distribution.
Fun times, right?
The Uncomfortable Truth About Who Owns Your Customer
Here's the dirty secret every CPG brand knows but nobody wants to say out loud: retailers own your customers. They always have. But now they're monetizing that ownership in ways that would make a Silicon Valley venture capitalist weep with envy.
Retail media networks leverage first-party data collected by retailers. This data includes customer purchase histories, shopping habits, and demographic details, allowing brands to create highly targeted campaigns. Unlike third-party data, which is often anonymized, first-party data offers actionable insights.
Translation: they know everything. What your customers buy, when they buy it, what they buy it with, how much they'll pay, and what makes them switch brands. And they're selling that knowledge back to you, one impression at a time.
The numbers are staggering:
35% of CPG advertising budgets are allocated to retail media
That's expected to increase to 50% within the next year
Retail media's share of global advertising is projected to grow from 20.6% to 23.2%
US retail media off-site ad spend is expected to grow 42.1% in 2025
This isn't a trend. It's a takeover.
Why Retail Media Networks Are Eating Your Lunch (And Your Budget)
They Have the Data You Dream About
Remember when you had to run focus groups to understand your customers? Cute.
Retailers have real-time data on actual purchase behaviour. Not intentions. Not surveys. Not "likelihood to purchase." Actual money changing hands for actual products.
Walmart's Luminate platform lets merchandising teams spot flavour trends early and iterate quickly. They know a trend is happening before you've even scheduled the meeting to discuss whether it might be a trend.
They Control the Moment of Truth
One of the biggest advantages of retail media networks is the ability to reach consumers actively shopping within the retailer's environment. These are high-intent customers who are already browsing products similar to what your brand offers.
Imagine a customer searching for snacks on an e-commerce site. Your competitor's ad appears right there, right then, with a compelling offer. Game over.
They're Building Walls Around Your Gardens
Every major retailer now has its own media network:
Amazon (obviously)
Walmart Connect
Kroger Precision Marketing
Target's Roundel
CVS Media Exchange
Even Instacart and Gopuff
Each one is a separate platform with separate rules, separate metrics, and separate invoices. It's like having to advertise on seventeen different versions of Google, except each one also controls whether your product stays on the shelf.
The Three Types of Retail Media (And Why You're Probably Focusing on the Wrong One)
On-Site: The Obvious Play
Ads on the retailer's website or app. Sponsored products, banner ads, search results. This is where most brands start and stop.
But here's the thing: everyone's fighting for the same real estate. It's becoming a race to the bottom where the highest bidder wins, margins evaporate, and small brands get squeezed out.
Off-Site: The Hidden Opportunity
This is where things get interesting. Retailers are using their data to target your customers across the entire internet. Social media, streaming platforms, third-party websites.
US retail media off-site ad spend is growing at twice the rate of on-site spend. Why? Because retailers can offer something Google and Meta can't: closed-loop attribution from ad to purchase.
In-Store: The Forgotten Frontier
Digital screens, smart shelves, interactive kiosks. In-store retail media ad spending is expected to increase by 47% in 2025.
CVS's new in-store video screens are proving popular, with over half of shoppers saying they find the information useful. Stop & Shop's "Savings Station" kiosks let loyalty members scan their cards for personalized deals right in the store.
This is where digital meets physical, and most brands are completely missing it.
Why Most Brands Are Failing at Retail Media
Mistake #1: Treating It Like Traditional Advertising
Retail media isn't just another advertising channel. It's a pay-to-play tax on your right to compete. You're not buying awareness; you're buying access to your own customers.
The mindset shift required: Stop thinking "advertising investment" and start thinking "cost of doing business."
Mistake #2: Focusing Only on ROAS
Return on ad spend is important. But retail media's real value goes beyond direct attribution.
Consider:
Share of voice in the digital shelf
Category growth influence
Competitor conquest
New customer acquisition
Cross-category expansion
26.4% of CPG companies work with five or more RMNs. They're not doing it for fun. They're doing it because presence across platforms is becoming table stakes.
Mistake #3: Ignoring the Data Opportunity
Retail media networks offer more than ad placement; they offer insights. Customer behaviour, competitive intelligence, category trends, pricing sensitivity.
Smart brands are using retail media not just to advertise but to inform:
Product development
Pricing strategy
Promotion planning
Distribution decisions
The Playbook for Winning at Retail Media
Step 1: Accept the New Reality
Retail media is not optional. It's not going away. It's not a bubble. It's the new cost structure of CPG marketing.
Budget accordingly. That means:
Reallocating from traditional media
Building it into your P&L from day one
Planning for annual increases
Step 2: Develop Platform Expertise
Each retail media network is different. What works on Amazon doesn't work on Walmart. What works on Walmart doesn't work on Kroger.
You need:
Platform-specific strategies
Platform-specific creative
Platform-specific measurement
Platform-specific teams (or agency partners)
20% of CPG ad-buyers use 11 or more tech platforms. This isn't inefficiency; it's adaptation to complexity.
Step 3: Master the Data Exchange
Retail media is a two-way street. You're not just buying ads; you're trading data.
Advanced strategies include:
Clean room collaborations (like Mondelēz with Pinterest and Albertsons)
AI-powered optimization
Cross-platform attribution modeling
Predictive audience building
One example: Mondelēz drove a 16% increase in incremental sales for Triscuit by leveraging collaborative data solutions across platforms.
Step 4: Think Beyond the Transaction
The best retail media strategies connect to broader business objectives:
For Innovation: Use retail media to test new products with specific audiences before broader rollout.
For Premiumization: Target high-value customers with premium product lines through precision targeting.
For Market Share: Conquest competitor customers during key shopping moments.
For Loyalty: Retarget your own customers with complementary products and subscription offers.
The Uncomfortable Future of Retail Media
Here's where this is all heading, whether we like it or not:
Consolidation Is Coming
Smaller retailers can't compete with the big players' tech and data capabilities. Expect partnerships, acquisitions, and platform consolidation. The long tail of retail media networks faces harsh realities: most small and midsize retailers lack the digital footprint to generate meaningful revenues.
Measurement Will Get Harder
As privacy regulations tighten and third-party cookies die, retail media networks will become even more valuable. They have first-party data in a world starving for it. But that also means less transparency, less independent verification, and more "trust us" metrics.
The Lines Will Blur
Retail media is expanding beyond retail. Uber Eats has an ad platform. DoorDash has an ad platform. Banks are launching retail media networks. Airlines are getting into the game.
Soon, every company with customer data and transaction capability will be a "retail media network."
AI Will Change Everything
Smart+ Ads, GMV Max, automated bidding: AI is already reshaping retail media. But we're just getting started.
Expect:
Fully automated campaign management
Predictive budget allocation
Real-time creative optimization
AI-powered negotiation between brands and platforms
The Action Plan That Actually Works
For Large Brands
Invest in infrastructure. Build dedicated teams. Develop proprietary technology. Treat retail media as a core capability, not an outsourced function.
Your advantages:
Budget to test and learn
Resources for platform specialization
Negotiating power with retailers
For Small Brands
Be surgical. Pick your battles. Focus on one or two platforms where you can win, rather than spreading thin across many.
Your advantages:
Agility to test quickly
Ability to find niches
Lower overhead to maintain profitability
For Everyone
Remember this: retail media is a necessary evil, but it's also a genuine opportunity. It offers targeting precision that traditional media can't match. Attribution that connects advertising to sales. Insights that inform entire business strategies.
The brands that win won't be the ones that resist retail media or resent it. They'll be the ones that master it, leverage it, and turn it into competitive advantage.
The Bottom Line Nobody Wants to Admit
Retail media networks are a $179.5 billion protection racket, and your brand is paying for protection.
But here's the thing: it's also the most effective advertising many brands have ever done. Higher short-term ROAS than traditional media. Stronger long-term sales lift. Better targeting. Clearer attribution.
The game has changed. The retailers have become the house, and the house always wins. But that doesn't mean you can't win too. You just need to understand the new rules, play them better than your competitors, and never forget who really owns the customer relationship.
Spoiler alert: it's not you.
Welcome to the future of CPG marketing. It's expensive, complex, and controlled by your biggest partners who are also your biggest competitors for margin.
But it's also where your customers are. And in the end, that's the only thing that matters.
