Why good retailers make bad ad tech decisions
This article from The Drum, written by commerce media columnist Kiri Masters, explores the organizational and financial challenges that hinder retailers from adopting new adtech, despite the availability of advanced technology. It describes the gap between technology capabilities and an organization's ability to approve and implement it, using the example of a retail media leader who manually adjusts an inadequate ad server to compensate for poor forecasting. The article outlines four eras of retail media: in-house builds, economic pendulum swings, cloud/composable architectures, and AI-era data requirements. It contrasts different RMN strategies, such as Costco's hand-built stack and Ace Hardware's use of CitrusAd, highlighting that tech choices often reflect historical timing rather than current needs. It discusses the 'budget clock' and 'career clock' that constrain decisions, and concludes with expert insights on proposition-led strategies versus technology-led ones, noting the trend of advertiser consolidation on major DSPs.
- Citing a retail media leader, the article states that a mid-sized US network uses an ad server built for legacy publishers, which fails to forecast retailer traffic patterns, leading to underdelivery.
- The article says that the retail media leader manually adjusts the platform's forecasts every week or two to avoid missing seven-figure ad revenue.
- GrowthLoop launched an end-to-end commerce media network solution in August (likely 2026) to help retailers set up or upgrade networks.

Retail media consolidation and incrementality scrutiny predicted
At the Advertising Club of New York's Commerce Media Exchange, Jason Colon of Horizon Commerce argued that the retail media landscape is facing a period of consolidation due to fragmentation and increased scrutiny from advertisers. He stated that the 'golden era of attribution' is over and that advertisers now demand proof of incrementality. Colon believes that not every retailer needs its own media network, and that many smaller networks lack differentiation. He predicts a 'forced consolidation' in the sector and emphasizes that commerce media should be integrated into holistic media strategies rather than being siloed. He also suggests that the distinction between retail media and general media will eventually disappear as data-driven commerce capabilities become standard practice.
