Retail Media Networks Shift from Performance to Brand Building

Executive Signal Summary

Retail media networks (RMNs), initially focused on conversion at point of purchase, are now positioning themselves as full-funnel brand-building channels. Retailers like Kroger, Walmart, and Instacart have formed partnerships to expand offsite capabilities, including streaming and social placements. However, media buyers and experts express skepticism about RMNs' effectiveness for brand building, citing inventory optimized for conversion, limited measurement, high costs of validation, and locked data behind spend thresholds. The article notes that for most RMNs, aside from Amazon, ad products are conversion-focused, making brand work difficult to prove. There are also internal budget disputes between trade/shopper and brand teams. Despite capabilities, experts argue RMNs are not yet functioning as true brand-building channels.
