For a C-suite executive weighing a retail media network (RMN) allocation, the decisive question is not whether the retailer reports a favorable return on ad spend—it is whether the spend caused sales that would not otherwise have happened, and whether the investment scales with your organization's operational capacity. The answer requires a tiered evaluation: match your monthly budget to a realistic network footprint, measurement approach, and non-media investment, then insist on independent, third-party measurement rather than retailer-reported dashboards. This article lays out that framework, explains why retailer-provided ROAS falls short for board-level decisions, and identifies the strategic value—first-party data access, product development insight, long-term brand building—that justifies RMN investment beyond immediate sales.
The C-suite Imperative: Strategic Evaluation of Retail Media Networks
Retail media has moved from an experimental line item to a nine-figure allocation question for many consumer brands, and that shift changes what counts as an acceptable answer. As Ipsos MMA, a marketing analytics firm, puts it, when the marketing function is asked to justify a nine-figure retail media allocation, "the retailer showed us a favorable ROAS" is no longer a sufficient answer. The company describes a structural tension: retailers have built substantial new profit centers around retail media and hold the leverage to enforce spending commitments, while brands must defend the spend internally.
Independent, third-party measurement changes that dynamic, Ipsos MMA argues, because when both sides operate from a shared, validated source of truth, conversations shift from justifying spend to optimizing it. The industry has acknowledged the gap. An ANA report on retail media networks concludes that "Retail media networks have a measurement issue...and therefore better measurement of RMNs is clearly required." For executives, that means evaluation cannot be delegated to the retailer's own reporting—it is a governance responsibility.
C-suite Retail Media Network Investment Framework
The framework below classifies RMN investment strategies into three monthly budget tiers, drawing on operational patterns reported by Improvado from brands managing retail media at scale. These figures are an illustrative planning model, not quotes for any specific company. The analytical logic: as spend rises, the viable network count grows, the measurement requirement shifts from retailer dashboards to portfolio-level incrementality, and the non-media investment—people, data integration, attribution—becomes a material budget line of its own.
| Budget Tier | Strategic Focus | Measurement Approach | Required Non-Media Investment |
|---|---|---|---|
| Under $50K monthly | Concentrate on 1–2 networks maximum, optimizing for direct ROAS | Basic retailer-provided dashboards | Handled within the existing marketing team |
| $50K–$500K monthly | Diversify across 3–5 networks, optimizing for category share | Advanced retailer dashboards plus third-party tools for cross-network reporting; begin cross-channel attribution to avoid double-counting conversions | 0.5–1.0 FTE for retail media operations and 0.5 FTE for analytics; data integration platform to centralize reporting |
| Over $500K monthly | Run campaigns across 5–10 networks; shift from individual network optimization to portfolio-level allocation and incrementality measurement | Enterprise data integration, full attribution, and marketing mix modeling | Dedicated RMN team (3–5 FTEs) and a strategic agency partnership |
The middle tier illustrates how quickly the operational burden compounds. Improvado's reported allocation model for the $50K–$500K range splits spend across Amazon Ads, Walmart Connect, a category specialist such as Target Roundel for beauty or Kroger for grocery, and a 5–10% testing budget for emerging networks. Beyond ad spend, the same tier carries data integration tooling of $30K–$80K annually, creative production of $20K–$40K, one-time attribution modeling setup of $15K–$40K, and incremental headcount of 0.5–1.5 FTE—totaling roughly 25–35% of annual ad spend in non-media costs. At the top tier, Improvado warns, unified reporting and advanced attribution are prerequisites rather than luxuries: without them, a brand running five to ten networks "will drown in operational complexity."
Beyond ROAS: Understanding True Incrementality and ROI
The core measurement problem is incrementality: separating sales your advertising caused from sales that would have occurred anyway. Every major retail media network provides advertisers with campaign performance reporting, as Ipsos MMA notes, but those retailer-reported figures do not distinguish coincidental sales from caused ones. A shopper who saw your sponsored placement may have bought your product regardless; crediting that sale to the ad overstates effectiveness and, at portfolio scale, misdirects capital.
This is why the framework treats measurement as a tier-dependent investment rather than a fixed cost. At low spend, retailer dashboards are a tolerable proxy while you test and learn. At mid spend, cross-channel attribution becomes necessary to avoid double-counting conversions across networks. At high spend, only enterprise data integration, full attribution, and marketing mix modeling can answer the question the board is actually asking: what did this allocation cause? The ANA's own programming reflects how hard this is—its knowledge center includes sessions on why retail media ROAS is difficult to gauge and how brands like Intel approach measurement and resource allocation—evidence that even sophisticated advertisers treat this as an unsolved discipline.
Unlocking Long-Term Strategic Value from RMNs
A C-suite evaluation that stops at incremental sales will systematically undervalue retail media. Research from Northwestern University's Medill Spiegel Research Center describes a value-based strategy that replaces fragmented, channel-based budget allocation with a focus on the consumer experience, balancing short-term sales objectives with long-term brand building. In that model, the seamless transition from awareness to purchase helps brands achieve incremental growth while enhancing visibility and relevance, anticipating consumer needs, informing product development, and ultimately increasing customer lifetime value.
First-party data is the other long-term asset. A Boston Consulting Group analysis of retail media by Lauren Wiener, Leora Kelman, Brad Jakeman, and Mark Abraham quotes a Kroger Precision Marketing executive: "Customer behavior is the heartbeat of retail media. Our loyalty program is the key to understanding our customers and guarding their trust in us." For an advertiser, that means RMN partnerships can yield audience and category insight that feeds innovation well beyond the campaign—though BCG also cautions that networks and media players are still working through the implications of new state-level data privacy regulations, a risk factor that belongs in any board-level assessment of data-dependent strategic value.
Asking the Right Questions: A C-suite Checklist
Executives can pressure-test any RMN proposal with a short set of questions drawn from the framework above. First: does our network footprint match our budget tier, or are we spread across more networks than our analytics can support? Second: what share of reported sales is independently verified as incremental, and what methodology—holdout tests, attribution modeling, or marketing mix modeling—produced that figure? Third: have we budgeted the non-media costs, from integration tooling to dedicated headcount, that the tier requires? Fourth: what first-party insights flow back into product development and brand strategy, and are we capturing customer lifetime value rather than only transactional lift?
The questions matter because the leverage sits with the retailer. Ipsos MMA's framing is blunt: retailers have the leverage to enforce spending commitments, and only shared, validated measurement rebalances the negotiation. An executive who cannot articulate the incrementality methodology behind the number has not approved an investment; they have accepted a vendor's self-grading.
Making Informed RMN Investment Decisions
The decision for C-suite executives is to adopt a tiered approach to RMN investment, prioritizing independent measurement of incrementality over retailer-provided ROAS, and recognizing long-term strategic value—first-party data access, product development insight, and brand building—beyond short-term sales. The budget tiers are illustrative planning boundaries, not prescriptions, and this framework evaluates RMNs from the advertiser's side rather than guiding a retailer building one.
The measurable indicator to monitor is the adoption of third-party measurement solutions and the integration of RMN performance data into broader marketing mix models to assess true incremental ROI and strategic impact. When that integration exists, the board conversation changes character: the question stops being whether the retailer's dashboard looks good, and becomes what the portfolio caused—a question your organization, not the network, is equipped to answer.
