Commerce Media ‘Firmly in the Growth Phase’, Finds SMG’s New Maturity Index

Why It Matters

The Index gives retailers and advertisers a common yardstick to prioritize capabilities, accelerating sustainable growth in a market where spend is rapidly expanding.

Key Takeaways

• 58% of networks classified as mid-market, 28% mature.
• 'What' dimension strongest predictor of overall maturity.
• 40% mid-market match mature on advertiser value ('How').
• AI, in-store automation drive next competitive edge.
• Index guides investment priorities, not a one-size scorecard.

Pulse Analysis

Commerce media has moved beyond early experimentation to become a core revenue driver for retailers, attracting billions in ad spend and prompting brands to allocate larger budgets to on‑site placements. Yet the rapid expansion has left the industry without a unified way to assess network sophistication. SMG’s CMN Maturity Index fills that gap by offering a granular, three‑dimensional framework that measures proposition strength, advertiser value delivery, and organizational integration. By quantifying these factors, the Index enables firms to compare themselves against global best practices and identify where to invest for maximum impact.

The Index’s early findings highlight that a robust ‘What’—the breadth of media channels, data assets and inventory—correlates most tightly with overall maturity. Meanwhile, the ‘How’ dimension, which captures service quality, transparency and strategic partnership, is already being mastered by a sizable slice of mid‑market networks, suggesting that execution excellence can offset gaps in other areas. Emerging capabilities such as AI‑driven insight activation, off‑site orchestration, and in‑store automation are flagged as the next sources of competitive advantage, indicating that future leaders will blend data‑rich propositions with sophisticated, automated delivery mechanisms.

For retailers, the practical value of the Index lies in its roadmap function. Companies can benchmark their current standing, pinpoint specific capability shortfalls, and allocate capital to the most strategic upgrades rather than spreading resources thinly across all functions. Advertisers benefit from clearer, more trustworthy media propositions, while the broader ecosystem gains a shared language that can accelerate consolidation and innovation. As commerce media continues to mature, firms that leverage the Index to build integrated, data‑driven networks are poised to capture sustainable growth and outpace peers.
