The Rise of Retail Media Networks for Ad Revenue
Retail has evolved beyond simply selling products on shelves. Today, major companies are transforming their websites and apps into powerful advertising engines. This shift represents the explosion of Retail Media Networks (RMNs). Brands like Kroger, Walmart, and Marriott are no longer just merchants; they are becoming media moguls, leveraging their customer data to build high-margin advertising businesses that rival traditional publishers.
Understanding the Retail Media Gold Rush
A Retail Media Network allows a retailer to sell advertising space on its own digital properties. When you search for “shampoo” on a store’s app and see a sponsored listing at the top, that is retail media in action.
However, this concept has expanded significantly. It now includes:
- On-site advertising: Banners and sponsored products on the retailer’s website.
- Off-site advertising: Retailers using their data to target shoppers on other websites or social media platforms.
- In-store digital media: Digital screens and smart carts inside physical locations.
The primary driver behind this trend is profit. Traditional retail operates on razor-thin margins, typically between 2% and 4%. Advertising revenue, by contrast, commands margins ranging from 70% to 90%. For a company like Amazon, their ad business generates billions in profit that subsidizes other lower-margin parts of the business. Now, everyone else wants a piece of that pie.
Why Data is the New Currency
The technical catalyst for this rise is the “death of the third-party cookie.” Apple has locked down privacy on iPhones, and Google is in the process of phasing out tracking cookies on Chrome. This makes it incredibly difficult for brands to target ads effectively using old methods.
Retailers solve this problem because they own First-Party Data. They do not need to guess what you might want to buy; they know exactly what you bought last Tuesday.
- Verified Purchase Data: Facebook knows you “like” coffee. Kroger knows you bought a specific brand of Folgers roast yesterday.
- Closed-Loop Attribution: Retailers can prove an ad worked. They can show a brand that a customer saw an ad on Monday and bought the product on Friday.
Spotlight: Kroger Precision Marketing
Kroger has become a standout example of how to execute this strategy correctly. The grocery giant utilizes its data science arm, 84.51°, to power Kroger Precision Marketing.
With nearly 60 million households shopping at Kroger, the company possesses massive amounts of data. They use this to help brands target specific types of shoppers, such as “price-sensitive parents” or “organic buyers.”
Kroger has successfully expanded beyond its own website. They allow brands to use Kroger’s data to buy ads on streaming TV services and audio platforms. If a brand wants to advertise a new healthy snack on a streaming service, they can use Kroger’s data to ensure the ad only reaches people who have purchased healthy snacks in the past six months.
Spotlight: The Marriott Media Network
While retail media started with grocery and big-box stores, it has moved into the hospitality sector. Marriott International launched the Marriott Media Network to capitalize on travel intent.
This network allows advertisers to reach travelers across Marriott’s digital channels, including their app and booking site. This is highly valuable for specific advertisers, such as:
- Airlines looking to sell flights to confirmed travelers.
- Local tour operators wanting to reach guests arriving in a specific city.
- Credit card companies targeting business travelers.
Marriott partnered with Yahoo to build the technology stack for this network. It represents a shift where “retail” media is really “commerce” media. Any company with a direct relationship with a consumer and a transaction history can build an ad network.
The Dominance of Walmart Connect
Walmart has aggressively chased Amazon’s lead with its platform, Walmart Connect. The results have been staggering. In recent fiscal reports, Walmart revealed that its global advertising business generated approximately $3.4 billion in annual revenue.
Walmart Connect creates unique opportunities that combine digital and physical worlds. For example, they sell ads on self-checkout screens and TV walls inside their thousands of stores. This allows a brand like Tide or Sony to reach customers right at the point of purchase, something traditional TV or social media ads cannot do.
Challenges in a Crowded Market
While the revenue potential is high, the market is becoming fragmented. Advertisers are now being asked to buy ads across dozens of different networks. A brand like Procter & Gamble cannot easily manage separate ad buys for Walmart, Target, Kroger, Dollar General, and 7-Eleven simultaneously.
This fragmentation is leading to a new phase of consolidation and partnership. We are beginning to see aggregators and software platforms that allow brands to buy ads across multiple retailers through a single interface. Despite these growing pains, the shift is permanent. Retailers have found a way to monetize their data, and they will not turn off that revenue stream.
Frequently Asked Questions
What is the difference between trade marketing and retail media? Trade marketing traditionally involves negotiating for physical shelf space or paper circular features. Retail media is the digital evolution of this, using programmatic technology to bid on digital ad slots and search rankings in real-time.
Why are margins so high for retail media? The retailer already owns the website and the audience. Setting up the ad tech requires an initial investment, but once it is running, the cost to serve a digital ad is incredibly low compared to the price advertisers pay.
Is this only for online shopping? No. Retailers are increasingly digitizing their physical stores. This includes smart screens on cooler doors, digital signage in aisles, and ads on checkout kiosks.
Do privacy laws hurt retail media networks? Actually, privacy laws help them. Regulations make it harder to track users across the open web (third-party data). Since retailers obtain consent directly from their shoppers (first-party data), they are in a safe and privileged position to serve ads.
