Omnicom launches cross-platform frequency measurement via Acxiom-Snowflake clean room
Omnicom Media Group has updated its cross-platform clean room capabilities to enable advertisers to measure and compare ad frequency, reach, and performance across multiple CTV platforms and linear TV. Built on Acxiom's identity infrastructure within Snowflake, the solution integrates VideoAmp's ACR data and Acxiom's Creative ID to help brands prevent ad overexposure and accurately attribute business outcomes.
Key Takeaways
- Integrated Acxiom’s Creative ID to track specific ad spot delivery across previously siloed streaming environments
- Combined VideoAmp ACR and set-top-box data to enable closed-loop attribution for linear and CTV campaigns
- Addressed 'negative reach' risks, cited in an OMG study where 51% of consumers blamed brands for poor ad experiences
- Enabled the measurement of cross-platform sequential storytelling and the impact of frequency on business outcomes
Why It Matters
This development moves the industry beyond aggregated frequency averages, which often mask significant individual overexposure. By merging Acxiom's identity graph with VideoAmp’s viewership data inside a controlled clean room, Omnicom is effectively dismantling the 'black box' measurement of major streaming walled gardens. This allows for more precise dynamic creative optimization and real-time budget reallocation between linear and CTV. Strategists should monitor whether rival holding companies achieve similar data-sharing concessions from publishers to maintain competitive benchmarking capabilities.
Additional Context
The rollout follows Omnicom’s $13.5 billion acquisition of Interpublic Group (IPG) in November 2025, which consolidated the industry’s two largest identity resolution stacks. Per The Street (June 2026), Omnicom has fast-tracked the integration of IPG’s Acxiom assets into its Omni operating system to create a unified AI-powered marketing layer. This measurement expansion is a core component of that strategy, aimed at proving ROI across the combined 2.6 billion global consumer profiles now under Omnicom’s management. In tandem with the technical launch, Omnicom is aggressive on the partnership front. Per PR Newswire (June 2026), the company recently announced a collaboration with Netflix at the Cannes Lions festival, blending Acxiom’s audience intelligence with Netflix’s AI-powered ad tech. This suggests a broader push by agency holding companies to move from simple inventory buying to high-fidelity, creative-level orchestration. Meanwhile, VideoAmp continues to scale its own infrastructure; per MarTech360 (April 2026), the measurement firm recently launched a commingled identity solution that claims to increase clean room match rates by up to 60% compared to single-provider models.
