Legacy Measurement Sabotaging Retail Media Growth
The IAB blog argues that traditional Marketing Mix Modeling (MMM) is increasingly insufficient for measuring retail/commerce media. With retail media networks (RMNs) providing deterministic, SKU- and transaction-level data, closed-loop reporting and incrementality testing, MMM’s reliance on aggregated historical inputs and spend variation can under-credit retail media and misinform budget allocation. The post explains structural mismatches—always-on activation, CPC/CPA and auction dynamics, and fragmented commerce signals across channels—that cause MMM to undervalue retail media. IAB recommends repositioning MMM for long‑horizon planning while using closed‑loop, causal measurement (randomized experiments, geographic lift tests, platform-level reporting) as the primary basis for retail media investment decisions. The article references IAB’s 'Guidelines for Incremental Measurement in Commerce Media' and quotes industry practitioners urging adoption of best practices to accurately capture retail media’s incremental sales impact.
Walmart's AI assistant Sparky drives CX gains and sales growth
Walmart U.S. President and CEO David Guggina highlighted at the Goldman Sachs Global Consumer and Retail Conference how AI is reshaping Walmart's operations and customer experience. AI-driven efficiencies have led to faster delivery and cost savings, reinvested into competitive pricing and CX. The retailer's homegrown AI assistant Sparky, now central to its experience improvements, saw weekly engagement grow 60% quarter over quarter and visual search capabilities led to a 57% spike in conversion. Sparky also drives 40% higher average order values. Walmart also benefits from external AI agents like OpenAI's ChatGPT and Google's Gemini, which deep link to Walmart, resulting in high conversion rates. This contrasts with Amazon's blocking of such agents. Guggina hinted at integrating Sparky into other areas like Vizio TVs.
