AdTech has never had more data, yet it has rarely been harder for brands and agencies to answer a simple question: what actually drove the result?
Clicks, conversions, and platform-reported performance have long served as proxies for success, shaping how campaigns are evaluated, budgets are allocated, and results are communicated. But they were never designed to measure business impact directly. They offer a directional view of activity rather than a definitive answer.
Clicks indicate interest, conversions indicate action, and platform-reported metrics reflect performance within a given environment. Each of these signals plays a role, but none of them, on their own, can confirm whether marketing led to a business outcome.
That limitation isn’t new, but it’s becoming more visible as signals shift and measurement becomes more fragmented. Measurement systems are under increasing strain, shaped by signal fragmentation, privacy constraints, and data environments that make it harder to connect media exposure to outcomes. In fact, 75% of marketers say their current approaches are falling short.
Performance can appear strong in one platform and materially different in another, making it harder to reconcile results across partners. Connecting campaign performance to actual business outcomes remains difficult.
As identity, data collaboration, and measurement become more strategic to marketing performance, organizations are looking for infrastructure that can connect data across partners while preserving neutrality, flexibility, and interoperability.
Why performance doesn’t always reflect impact
Even when data is available, it doesn’t always tell a complete or accurate story.
A conversion after an ad exposure may suggest a relationship, but it doesn’t establish causation. Attribution models favor what’s easiest to measure, and platform-reported metrics often reflect biases toward their own ecosystems. Over time, this creates a version of performance that can appear accurate while overstating actual impact.
Measurement should move from signals to conversions, then to verified outcomes, and ultimately to incrementality. Each step brings measurement closer to understanding true business impact. In practice, most strategies stall in the middle, treating conversions as the endpoint even though they don’t show whether marketing drove the result.
This creates a gap between what’s measured and what matters. Incrementality is gaining focus because it isolates what changed due to marketing, separating true impact from what would have happened anyway. Industry guidance increasingly reflects this shift, recognizing incrementality as a reliable way to measure causal impact in a fragmented, privacy-first ecosystem.
As AI and agentic technologies become more involved in planning, optimization, and decision-making, the quality of the underlying identity and data foundation becomes increasingly important. Reliable outcomes require trusted identity and interoperable data.
The infrastructure shift: Why CAPI matters now
Measurement is evolving at both a conceptual and technical level.
As browser-based tracking becomes less reliable, the industry is shifting toward server-side approaches, including conversion APIs (CAPI). These approaches create a more direct, durable connection between advertiser data and platform systems, reducing reliance on signals limited by browsers and privacy controls.
Platforms are reinforcing this shift. Meta positions CAPI as a way to improve data quality, measurement accuracy, and optimization by enabling more complete event capture. Google similarly emphasizes server-side tagging to improve data control, resilience, and performance in modern measurement environments.
On their own, these approaches don’t solve the measurement challenge. Combined with identity, they create a stronger foundation for connecting marketing activity to real outcomes.
Stronger data collection infrastructure is most effective when paired with interoperable identity and privacy-first governance, giving marketers greater confidence in how data is connected, activated, and measured across environments.
Identity as the connective layer
Identity resolution is a key enabler of that foundation. By connecting identifiers across platforms, devices, and environments, it helps marketers tie exposure to consumers and, ultimately, to real-world outcomes. Without it, measurement stays siloed across platforms and channels. With it, marketers can see how activity across environments contributes to a single outcome.
Interoperable identity is becoming more than a marketing capability. It increasingly serves as a foundational layer that helps brands, agencies, publishers, platforms, and partners collaborate across a growing number of data and media environments.
Industry efforts around data clean rooms, interoperability, and privacy-safe collaboration all address the same challenge: how to connect data across environments without relying on outdated or fragile signals. Solutions that strengthen identity resolution within these environments improve match rates between partners, making collaboration more effective and measurement more complete.
As collaboration expands across clean rooms, platforms, and activation channels, marketers benefit from identity frameworks that support interoperability rather than limiting how data can move across the broader ecosystem.
What brands and agencies should expect next
For brands and agencies, the focus is shifting from what appears to perform within a platform and toward what drives results. That requires looking beyond platform-reported metrics, asking more of measurement partners, and incorporating incrementality into how success is defined.
It also requires investment in identity and measurement that enable outcome-based measurement. Without that foundation, even advanced reporting will struggle to provide a clear view of performance.
That foundation should include trusted consumer data, transparent governance practices, and identity capabilities that can adapt as technology, privacy expectations, and AI-driven workflows continue to change.
Many organizations are also evaluating how measurement, identity, and activation strategies can maintain long-term flexibility across agencies, platforms, publishers, commerce media networks, and emerging channels.
What this shift means for AdTech
Reporting within platforms or optimizing intermediary metrics is no longer enough. Success increasingly depends on demonstrating how marketing activity translates into business results across channels and environments.
As marketing systems become more automated, brands need visibility into the data and identity layers informing those decisions, along with confidence that those systems are operating on accurate, privacy-safe consumer information.
That shift requires interoperable identity, cross-platform measurement, and infrastructure that supports more complete and reliable data collection. It also requires validating whether marketing drove incremental business impact, rather than simply reporting observed conversions.
Independent identity and neutral data infrastructure can help support that effort by giving organizations the flexibility to work across partners, platforms, and channels while maintaining consistency in measurement and audience understanding.
This means building systems that connect exposure to outcomes, measure incremental impact, and link media investment and business results. Clicks and conversions remain useful, but their limitations are becoming more visible as reliability declines.
Trusted identity, privacy-safe data collaboration, and transparent measurement are becoming central to how marketers build durable strategies that can adapt as the ecosystem continues to change.
Measurement will be defined by the ability to connect marketing activity to verifiable outcomes, with incrementality at the center of understanding true impact.

Tom Rolph, VP EMEA at Tapad, part of Experian, says that ad-sponsored streaming services can be successful if they can deliver a higher quality viewer experience than other streaming services. Last week, Hulu, the streaming service acquired by Fox and now owned 60 per cent by Disney, announced it will be regularising its ad loads. The streaming service will be bringing ad breaks down to 90 seconds in an effort to deliver a better viewer experience. This is a positive move from Hulu and one which other ad-supported streaming services should follow in order to be successful in a competitive market. Previously ad breaks on Hulu could vary wildly, from 180 seconds to 240 seconds, due to existing deals with its three owners: Disney, Comcast and AT&T. Over in the UK, we haven’t suffered from quite as inconsistent an approach as in the US, but there is still viewer frustration with the ad experience on ITV Hub and All4, where the problem tends to be over exposure of the same ad. Therefore, this move to standardise ad break lengths for streaming platforms is one that should be embraced on both sides of the pond. An important shift in this space will be to limit the number of ads during each show, but have better ad targeting to minimise repetitive advertising and increase the ROI of ad spend. All of which can be accomplished by investing in identity resolution products that can support CTV devices. Last year Ofcom found that in the UK subscriptions to Netflix, Amazon and NOW TV have risen above those to traditional pay TV services. With Netflix and Amazon both ad-free and NOW TV only a limited ad funded model, it’s clear that there is a growing appetite for ad-free viewing models. A fact that is only further supported when you consider the role of the BBC and BBC iPlayer. But the picture isn’t entirely negative for ad-funded models. There is demand for great content on ad-funded services in the UK, with ITV Hub boasting over 1bn requests and 540m hours of TV watched. The ITV Hub mobile app has also been downloaded on over 27m devices across the country – with over 22m people now registered to ITV Hub database, including more than half of Britain’s 16-24 year olds. However, to continue to attract and retain younger viewers, the experience will have to improve. There are several areas where ad-supported streaming providers need to improve in order to remain top players in this space: Ad experienceAs explored above, both volume and repetition of ads can be a turn off for viewers, but with Brits already spending a total of £303.16m every month on TV streaming services, according to Finder.com, there is potential for free, ad-funded models to flourish as people hit a limit on what they are willing to spend. There are already signs of improvement with the ad experience, with ITV just signing a deal with Amobee to allow for addressable ads on ITV Hub, while Sky’s AdSmart technology remains best in class and has now crossed over the pond to be used by Comcast stablemate NBC. Server reliabilityA cursory search finds little evidence of ongoing reliability problems with Netflix, but much evidence of problems with ITV Hub and All4, which are both prone to crashing. To compete with bigger players with massive server farms, server capacity needs to be tackled. This is especially true when it comes to live events, where many people will recall ITV Hub’s famous fails during the World Cup. While even some of the larger players have had similar streaming issues (for example, Amazon’s move into live sports streaming when they had to pull UK streaming of the US Open Tennis due to user complaints), viewing experience should be prioritised as the space gets increasingly competitive. Getting the content rightAmazon and Netflix have huge content budgets, but UK broadcasters remain strong in this regard, Channel 4 has enjoyed viewing figures of 7.5m for the Great British Bake Off, while ITV pulled in 13.7m for I’m A Celebrity. By building on UK-specific content that speaks to UK audiences, ad-supported streaming services can continue to pull in more viewers. Mobile accessMore and more Brits are choosing to watch TV content on their smartphone or tablet, according to UKOM-approved comScore data. In fact, 6.5m adults visited the BBC iPlayer app to watch video on either a smartphone or tablet, edging out Netflix which attracted 5.8m Getting the experience right on mobile, with the option to download content so it can be viewed in areas of low or no signal, is key.If UK ad-supported TV stations can crack these key areas for their Connected TV offering then they will be set up to succeed and offer a true home-grown alternative to the US streaming giants.

Tapad’s, part of Experian, SVP of Identity shows us how marketers might communicate seamlessly through emerging channels like voice, the smart home, and, yes, podcasts.In his relatively new role as senior vice president of identity at Tapad, a part of Experian, Ajit Thupil keeps a close eye on the evolution of marketing as it becomes more intent on using data and identity technology to track ROI. Here he sits with Chris Wood at Tapad’s New York offices to discuss the future of identity. (To capture the inventive atmosphere at this location, the room they chatted in was named after Leonardo da Vinci.) For Thupil, it all comes back to the customer, whether it’s a brand client or a consumer. Brands want measurability and customers demand a seamless experience across the many devices they use in a day. While consumers are understandably reticent about giving up personally identifiable information (PII), current identity solutions use anonymous data profiles to connect the dots at the individual or household level. Given the frequency that users switch devices, along with their tendency to share bigger screens like TVs, there’s no dearth of challenges for this “head of problem solving” to solve.
