As the consumer path to conversion becomes more complex than ever, brands are struggling to achieve combined channel reporting due to fragmented data across partners and publishers.
In the current media landscape, it’s important to have a unified view of performance across all channels to make more informed decisions about ad spend and maximise ROI. That’s where cross-media measurement comes in.
Cross-media measurement connects the dots across channels such as digital, social, TV, and more. This enables marketers to understand what’s working, where to optimise, and how to drive real outcomes. Once considered a sophisticated bonus in the world of attribution reporting, today it’s non-negotiable — and a key indicator of marketing measurement maturity.
What is cross-media measurement and why does it matter?
Cross-media measurement enables you to evaluate the performance of your marketing campaigns across channels — including TV (linear, streaming, CTV, and OTT), digital (programmatic and mobile), social, and audio.
Unlike traditional channel-by-channel reporting strategies that measure impact in silos, cross-media measurement enables connectivity across all those different data sources for a unified and standardised view of performance across your media plan. This provides the accurate insights needed to optimise media mix, enabling you to more effectively allocate budget and manage frequency across campaigns and channels.
As a result, it becomes possible to answer big-picture questions like:
- Where are your audiences actually showing up across the ecosystem – and where aren’t they?
- How is your media working together to influence outcomes like website visits and sales?
- Which channels are driving the most incremental reach?
- Which audiences are responding, interacting, and converting across publishers and channels?
Challenges of modern media measurement
Achieving true cross-media measurement has been one of the most persistent challenges in advertising. Until recently, brands and agencies have struggled to capture a robust and unified view of performance across channels. That’s largely due to the structural barriers built into today’s media landscape, including:
- Media fragmentation and signal loss
- Evolving privacy regulations
- Isolated data environments
- Inconsistent measurement standards across channels
Media fragmentation and signal loss
The proliferation of digital channels and streaming services has made consumer behaviour harder to understand. People move seamlessly between screens and online identities, distributing their activity across multiple email addresses, device IDs, and IP addresses. At the same time, many traditional signals like cookies are fading.
Without a way to recognise individuals or households across environments, you’re left with gaps in reach analysis, inaccurate impression tracking, and incomplete attribution that makes it difficult to understand which channels or touchpoints are driving results.
Privacy regulations
A growing list of state-level data privacy regulations adds to the complexity of compliance with existing frameworks like GDPR. As policies tighten, marketers face increasing limitations on how they collect, share, and activate data across channels. Even first-party data can be difficult to scale across ecosystems due to compliance concerns.
Data silos
Publisher data lives in different places across clouds and data warehouses, making it hard to connect in one place while maintaining the privacy requirements of each partner.
Connecting your own first-party data is barely any easier. Sharing data across siloed teams, brands, or business units can be just as difficult as navigating across partners. These disconnects make it nearly impossible to build a consistent, cross-channel view of performance.
Inconsistent metrics across channels
Each publisher, channel, and demand-side platform (DSP) reports performance differently. For example, one might define a video view as three seconds, while another defines it as 15 seconds. Engagement on one channel might mean likes and shares; on another, completed views or conversions.
This lack of standardisation makes it difficult to compare performance or benchmark success. And when data sets can’t be aligned — either because of incompatible schemas or restricted access — cross-channel measurement becomes a matter of inference rather than accuracy.
The role of clean rooms in cross-media measurement
As brands navigate biased publisher reporting and growing privacy regulations, clean rooms have emerged as a foundational tool for enabling neutral cross-media measurement through responsible data use.
These environments have controls that allow two or more parties — such as brands, media partners, and measurement providers — to collaborate with data without exposing consumers’ personally identifiable information. By facilitating responsible, controlled data collaboration, clean rooms help marketers connect siloed signals and gain a neutral, unified view of campaign performance.
Clean rooms are especially powerful when paired with an identity infrastructure that can resolve fragmented signals to a persistent identifier. Together, these capabilities help marketers bridge the gap between channels and build a clearer picture of how their campaigns are performing across today’s complex media landscape.
Benefits of cross-media measurement
When implemented effectively, cross-media measurement provides a strategic advantage by enabling you to align performance insights with business outcomes. A few benefits of cross-media measurement include:
- Holistic view of campaign performance
- Improved audience targeting and engagement
- Consistent and personalised customer journeys
- Accurate attribution and ROI analysis
Holistic view of campaign performance
Instead of analysing each channel in a vacuum, cross-media measurement provides a comprehensive understanding of how campaigns are performing across channels. It standardises reporting by uniting frequency metrics (such as views and impressions) into a single, cohesive framework. By resolving identities across channels (for example, determining when an ad is sent to both a mobile device and connected TV in the same household) you’re able to identify and account for duplicate exposures to measure true reach.
This high-level perspective provides a clear picture of how different tactics are working together or overlapping inefficiently, enabling smarter media planning for more efficient campaigns.
Improved audience targeting and engagement
Cross-media measurement helps you see where your audience is most active, how often they’re exposed to your campaigns, and which touchpoints are driving meaningful interactions. This clarity enables more precise targeting and sequencing across touchpoints, which reduces overexposure and ad fatigue while improving relevance. It also opens the door to smarter experimentation and segmentation strategies grounded in real behavioural insights.
Consistent and personalised customer journeys
Fragmented experiences can confuse or annoy customers. Cross-media measurement supports consistency by allowing you to design customer journeys that feel coherent and personalised.
Imagine a traveller who books a ride share to the airport after seeing a promo in their airline app, watches a destination-specific ad on their in-flight seatback screen, and then checks into their hotel room, where their TV welcomes them with a personalised offer.
With better visibility into the full journey, it becomes possible to orchestrate messaging in a way that aligns with user intent and funnel stage.
Accurate attribution and ROI analysis
Rather than relying on last-touch models or siloed channel reports, cross-media measurement allows you to tie conversions back to the full path of exposures. For example, if a customer sees a streaming TV ad, later clicks a display ad, and eventually converts after a branded search, a cross-screen measurement model can account for each of those touchpoints, not just the final click.
This granular view is critical to understanding the true value of upper-funnel tactics like connected TV, which often get undervalued in traditional attribution frameworks. With clearer insights into what’s working and what’s not, you can confidently allocate spend and measure true marketing impact.
Use cases for cross-media measurement
Whether you’re buying, selling, or analysing media, a unified measurement approach can drive better outcomes and stronger partnerships.
For advertisers
Advertisers that deploy a cross-media measurement model gain a clearer view of how their media investments are performing across channels and partners. With deduplicated reach, unified frequency data, and accurate attribution, they can:
- Optimise media mix and allocate budgets based on real performance
- Reduce waste from audience overexposure or channel overlap
- Understand how upper- and lower-funnel tactics work together to drive conversions
- Improve personalisation and sequencing across the customer journey
Cross-media measurement enables advertisers to move from reactive reporting to proactive strategy, grounded in trustworthy data.
For agencies
Agencies are tasked with delivering performance, proving value, and managing complex media portfolios. Access to holistic performance insights across channels enables them to streamline reporting workflows with standardised metrics, making it easier to showcase results to clients.
For publishers
Publishers and media owners need to show how their channels contribute to advertisers’ goals. In a competitive media environment, publishers that support cross-media measurement stand out as premium, performance-driven partners because they can demonstrate the unique, incremental value of their audiences within broader campaigns. This makes it easier for advertisers to compare performance across partners and confidently include them in future media plans.
For measurement providers
As advertisers seek more sophisticated, responsible measurement solutions, providers that offer cross-channel accuracy — and help align on consistent methodologies and success metrics — will become increasingly valuable partners in driving marketing performance.
What to look for in a cross-media measurement partner
Choosing the right partner is essential to unlocking the full value of cross-media measurement. While many providers promise unified reporting, few offer the technical depth, ecosystem reach, and security needed to support real-world campaigns across today’s fragmented landscape. Below are a few of the key considerations to keep in mind when looking for a cross-media measurement partner:
- Strong partnership network
- Connectivity capabilities
- Flexible, easy-to-access insights
- Strict neutrality
Strong partnership network
No single platform holds all the data required to deliver true cross-media insight. Look for a partner with a broad and trusted partnership network of integrations that enables secure and expansive data collaboration among media owners, publishers, clean rooms, and measurement providers. Strong connections to data partners increase your ability to measure effectively across the environments where your customers spend time and build a more complete view of performance.
Connectivity capabilities
Identity is the foundation of accurate measurement. A strong partner should offer robust identity resolution that supports multiple digital identifiers and offline data through clean room compatibility. Interoperability with existing systems – across identifiers, platforms, partners, and clouds – enables broader connectivity to premium publisher data. Together, these capabilities make it possible to measure true reach, engagement, and outcomes without relying on outdated tracking methods.
Flexible, easy-to-access insights
Rather than locking you into rigid reporting formats, cross-media measurement should enable you to access and apply insights in the ways that best support your goals. Depending on whether you want to prioritise campaign optimisation, long-term media planning, or advanced analytics, top measurement partners can provide the flexible reporting you need through persistent identity and API integrations with your preferred analytics or visualisation tools.
Strict neutrality
A trustworthy cross-media measurement partner will adhere to ethical standards for responsible data use. Ensure the platform you partner with enforces strong data governance standards and controls to ensure sensitive data is not exposed during performance measurement.
