Advantages and limitations of Retail Media Networks

In this blog

Retail Media Networks (RMNs) are experiencing explosive growth, reshaping the digital advertising landscape. According to BCG, the retail media market is expected to reach $100 billion in the US alone by 2026, representing 25% of total digital ad spend. This momentum highlights the shift toward first-party data, closed-loop measurement, and a new era of retailer-brand collaboration.

Behind this surge is a clear value proposition: RMNs are proving to be an exceptional strategy for third-party brands because of their VIP access to retailers’ first-party customer data. This allows for more relevant and personalized advertising experiences (a win-win for retailers and brands alike).

Throughout the blog, we will dig deeper into the value, limitations of retail media networks , and how they can be optimized when paired with promotions

What is a Retail Media Network?

A retail media network is an advertising ecosystem that allows brands/vendors to purchase space on various online channels (e.g., website, mobile app) to reach their target audience. 

RMNs can either be:

  • Retailer-owned retail media networks
  • Third-party managed retail media networks 


To build a retailer-owned RMN, a company must invest heavily in budget, resources, and data . As a result , only big-box retailers are investing in this space like Target, Home Depot, Kroger, and Costco. 

Smaller, mid-market retailers are relying on third-party services to manage all discussions and purchasing decisions with vendors.

The value of retail media networks

Retail media networks have many benefits for both brands and retailers. Here are a few key highlights from both perspectives:

Brand advantages of retail media networks

    1. Make better-informed decisions on campaigns: Retail media networks provide brands with access to first-party shopper data, giving marketers deeper insight into purchasing behavior and customer segments. This allows brands to design smarter, more targeted, and more effective campaigns.
    2. Maximize return on ad spend (ROAS): By advertising directly to high-intent shoppers, brands can significantly improve ROAS. RMNs make it possible to reach customers who have a strong likelihood of converting — improving both awareness and sales performance.
    3. Diversification of venues: Retail media networks allow brands to increase product visibility wherever customers shop. The list of venues has grown for brands to reach their desired audiences, allowing them to invest in endcaps, promos, RMNs, etc. 

In a study conducted by Merkle as reported in eMarketer, retail media networks are rising in demand for multiple factors, with retailers’ first-party data access being first on the list.
