According to recent reports, retail media and digital advertising are entering a stricter transparency phase as new industry standards focus on accountability, standardised measurement, and consumer protection. The updated guidelines impact how ad costs are disclosed, how performance is measured across channels, and how retailers report data to advertisers.
What the New Retail Digital Ad Transparency Guidelines Cover
The latest retail digital ad transparency guidelines apply to Retail Media Networks (RMNs) and commerce-driven advertising across online and in-store environments.
The objective is to replace opaque reporting with auditable, consistent, and comparable data across platforms.
Updated Retail Media Measurement Standards (V2)
Recently, IAB Europe updated its retail media standards following an extended public consultation involving retailers, brands, agencies, and ad-tech providers.
Key Enhancements in the Updated Standards
- A clearer and refined measurement funnel
- Standardised definitions for gross sales and net sales
- New metrics designed for quick commerce
- A formal definition of incrementality, including approved methodologies
- Expanded new-to-brand and new-to-category measurement windows
- A dedicated framework for measurement and insights platforms
The standards also reaffirm a 30-day lookback window as the default, while requiring flexibility for custom reporting needs.
Stricter Cost and Markup Transparency in Retail Media
Retailers are now expected to disclose clearer information on:
- Media costs and markups
- Funding sources for campaigns
- Differences between onsite, offsite, and in-store media pricing
Retail networks must also provide separate reporting for their own inventory versus third-party publishers, ensuring advertisers can clearly identify where spend is allocated.
Digital Advertising Price Transparency Rules
Earlier this year, new advertising transparency rules were introduced requiring:
- Clear disclosure of total ad costs, including all fees
- Elimination of misleading pricing representations
- Consistent price visibility before and after purchase
These rules aim to prevent “bait-and-switch” pricing practices across digital advertising environments.
Standardised Metrics Across In-Store and Online Media
One of the most significant changes is the push for metric standardisation across:
- Onsite retail media
- Offsite digital placements
- In-store digital displays
Retailers must now report metrics such as ad plays, gross impressions, and viewable impressions using common definitions, improving cross-channel comparability.
Auction Transparency and Media Buying Accountability
Proposed standards also encourage platforms to disclose:
- How auction winners are selected
- How pricing is determined
- What factors influence bid outcomes
This move reduces “black-box” buying and supports informed decision-making for brands.
Core Principles Behind the New Guidelines
The updated retail digital ad transparency guidelines are built on three core principles:
- Accountability: Shift from opaque reporting to granular, auditable data
- Privacy-First Design: Greater reliance on consent-based, first-party data
- Accuracy: Improved filtering of invalid traffic and clearer viewability reporting
Together, these principles aim to strengthen trust between retailers, brands, and consumers.
What This Means for Brands and Retailers
Brands advertising through retail media networks will need to:
- Re-evaluate reporting frameworks
- Demand clearer cost breakdowns
- Align internal measurement with standardised definitions
Retailers, meanwhile, must upgrade systems to support transparent reporting without compromising user privacy.
