Retail Media Networks (RMNs) turned first-party customer data into a premium advertising asset as third-party cookies faded. Loyalty programs are the primary source of that data, giving retailers identity, purchase history, and the contextual signals advertisers pay for. RMNs often deliver operating margins far above core retail, so improving data quality is a direct revenue lever.
The Data Foundation of Retail Media
Loyalty records provide deterministic identity and granular purchase behavior. Advertisers value that certainty because it improves targeting, attribution, and measurement. With clear identity, retailers can monetize placements at higher CPMs and demonstrate performance to brand partners. But the value of loyalty data depends on how complete and representative it is of the full shopper universe.
Bridging Key Loyalty Gaps for RMN Success
Unseen Customers and Incomplete Profiles
Retailers typically see that roughly 55% of revenue comes from non-loyalty customers. Within loyalty cohorts, a scan gap means 30 to 50 percent of members cannot be tied to in-store or digital behaviors in practice. These blind spots create audience leakage, weaken targeting, and reduce measurable reach for advertisers.
Missing Wallet Share Insights
Even identified loyalty members often lack reliable wallet share metrics. Without a sense of how much of a shopper’s category spend occurs with the retailer, RMNs cannot prioritize high-value audiences or optimize bids for incremental sales. That erodes ad ROI and depresses the CPMs brands are willing to pay.
Driving Higher Performance Through Data Precision
Closing identity and behavioral gaps raises ad relevance and measurable lift, which translates into higher CPMs and longer advertiser relationships. Mobile-derived identity graphs and privacy-compliant deterministic linking can extend profiles beyond loyalty signups and fill scan gaps. Combining transaction records with broader mobile and zero-party inputs produces a holistic view of shopper value and behavior.
For RMNs, data quality is the competitive differentiator. Retailers that move from partial loyalty snapshots to a unified, retailer-centric customer graph will capture more revenue, command premium pricing, and deliver superior advertiser ROI.
