What Advertisers Actually Need From Commerce Media Measurement | Behind the Numbers Special Edition Podcast

The panel opened with a stark observation: retail media budgets are growing faster than measurement tools. Both Matt Barresi and Jack Kniper noted each network delivers its own attribution window, KPI definitions, and reporting format, creating fragmented data that makes apples‑to‑apples comparison nearly impossible. Consequently, many advertisers still rely on platform‑reported metrics instead of rigorous incrementality tests. The speakers agreed the first step toward reliable insight is to move beyond surface numbers and invest in controlled experiments that prove true lift, especially when spend thresholds justify the cost.

Traditional ROAS, once the North Star for retail media, is losing relevance for many CPG brands. Matt explained that incremental return and lifetime value now drive budget decisions, capturing long‑term brand health and repeat purchase potential. Jack added that speed to insight is equally critical; while statistical rigor remains essential, the industry is adopting rule‑of‑thumb thresholds and rapid‑cycle experiments to accelerate decisions. This balance lets marketers act on early signals without waiting for lengthy data pipelines, keeping campaigns agile in a real‑time commerce environment.

Internal alignment and transparent vendor partnerships were the final theme. Both companies described dedicated analytics teams that create a single source of truth, common KPIs, and shared language across brand, media, and commerce groups. Matt emphasized that true partnership means sharing blinded performance data so agencies can benchmark against alternative investments, fostering joint problem‑solving instead of pure selling. The panel’s wish list converged on industry‑wide standardization of attribution windows and metric definitions—a step that could unlock more efficient spend allocation and boost credibility of commerce media measurement.
