# ANA warns marketers against overreliance on retail media data Trade association aims to establish shared metrics for a growing but opaque advertising channel. - **Source:** [Marketing Dive](https://www.marketingdive.com) - **Published:** 2026-08-18 - **Topic:** [Marketing](https://brifing.si/c/marketing) - **Original article:** - **On Brifing:** https://brifing.si/s/49343435-b764-4731-b995-f49d06d77b1e ## Growth in retail media market Retail media networks are capturing an increasing share of marketing budgets with the rise of e-commerce. In 2022, US spending on this channel exceeded $40 billion. Despite this rapid growth, the lack of measurement standards poses a significant industry challenge. Brands struggle to compare data from different platforms, leading to inconsistent performance evaluations. ## ANA's concerns The Association of National Advertisers (ANA) has cautioned marketers against blind trust in retail media data. The trade body highlights how data quality issues, lack of transparency, and inconsistent measurement methodologies could lead to misleading results. Particularly concerning are ROI calculation discrepancies that might negatively impact decision-making processes. ## Collaboration with IAB ANA is working with the Interactive Advertising Bureau (IAB) to develop common language and measurement standards for the industry. This initiative aims to make retail media data more reliable and comparable. Both organizations plan to release a set of guidelines by the end of 2023, addressing key pain points in the rapidly growing sector. ## Data transparency challenges Retail media platforms currently lack sufficient transparency in their data collection and reporting methodologies. Some platforms only provide proprietary metrics, while others don't allow third-party verification tools. This inconsistency makes performance evaluation difficult for brands and can lead to budget allocation errors worth millions of dollars. ## Impact on marketing decisions ANA's warning carries particular weight for brands with substantial marketing budgets. As investments in retail media grow, data-driven decision making becomes more critical. Inaccurate data could result in inefficient allocation of marketing budgets, potentially wasting millions in advertising spend. ## Industry response Some major retail media platforms have responded positively to ANA's call, making transparency commitments. However, industry experts believe broader collaboration and pressure are needed for true standardization. Participation from key players like Amazon, Walmart, and Target will be crucial for meaningful change. ## Global implications The standardization efforts starting in the US are expected to influence the global marketing ecosystem. Trade associations in Europe and Asia are considering similar initiatives. The global retail media market is projected to exceed $100 billion by 2025, making these standards increasingly important worldwide. ## Recommendations for marketers ANA advises marketing professionals to question retail media data and implement cross-verification practices. Using multiple data sources, leveraging third-party verification tools, and demanding more transparency from platforms can lead to better-informed decisions. These practices become especially critical as retail media claims larger portions of marketing budgets. ## Sources covering this story - https://www.marketingdive.com/news/ana-cautions-marketers-against-overreliance-on-retail-media-data/828109/ — --- _Summary written by Brifing from the original reporting.
