As the digital ecosystem becomes more complex, managing multiple identifiers for consumers has emerged as a significant challenge. From cookies and IP addresses to mobile IDs and universal IDs, marketers and platforms face increasing difficulty in maintaining a unified view of their consumers. Without a coherent identity strategy, campaigns can suffer from poor targeting, limited personalization, and flawed attribution.
Experian understands these challenges and offers solutions to help our partners navigate the complexities of a multi-ID landscape. By utilizing both digital and offline data, we provide the tools to unify fragmented identifiers and maintain a persistent view of consumers. As a result, marketers and platforms get rich insights, accurate cross-device targeting, improved addressability, and measurable advertising.
The shifting identity landscape
For years, the industry has relied on cookies to identify consumers across devices and platforms. However, with ongoing signal loss, including the uncertainty around cookies, and the evolution of privacy regulations, the digital identity landscape has grown more complicated. As consumers hop from one device to another, they are now represented by multiple signals, each tied to a different aspect of their digital behavior.
While this shift brings complexity, it also opens the door for innovation. Marketers and ad platforms now have the opportunity to rethink their identity strategies and adopt more flexible approaches that are not reliant on a single identifier.
This is where Experian comes in.
Connecting the dots: A holistic view of the customer journey
Our identity solutions are designed to help manage today’s multi-ID ecosystem by connecting digital and offline identifiers to a single customer profile. This creates a unified view of the consumer, and when combined with our understanding of customer behavior (e.g. demo, interests, shopping patterns) marketers and platforms get both insights about their customers and the addressability to reach them across channels.

Four examples of what you can do with a strong identity foundation
- If an advertiser wants to make its first-party data more addressable, it can utilize our Digital Graph with universal IDs, hashed emails (HEMs), and connected TV (CTV) IDs to extend its reach.
- A publisher who wants to gain further insights into their audiences and create private marketplaces (PMPs) can achieve this goal with the use of our Digital Graph with hashed emails, universal IDs, mobile ad IDs (MAIDs), CTV IDs, and IPs. The publisher can use this in concert with Marketing Attributes to understand age, gender, household income, buying behavior, and more. The publisher can connect marketing attributes to the Digital Graph via our Living Unit ID (LUID) to understand more about consumers that fall into their segments.
- A demand-side platform (DSP) who wants to extend first-party and third-party audience reach across all digital devices on their platform will use the Digital Graph with all digital IDs to allow users of their platform to select cross-device extension against first-party and third-party audiences.
- A retail media network (RMN) can use our Offline and Digital Graphs to connect in-store and online purchases to a household profile—even when purchases are made by different people. The RMN can then reach that household across digital media platforms and accurately attribute the in-store purchase back to digital ad exposure.
Identity as a strategic asset: Today and in the future
In our paradoxical world where consumers are represented by multiple identifiers, yet marketers and platforms face signal loss, identity is more than a technical issue—it’s a strategic asset. The ability to unify identity data into a single profile provides marketers with the customer intelligence needed to drive growth and stay competitive. Here’s how we do it:
- Deep, persistent customer understanding: With roots in offline, deterministic data like names, addresses, and emails, we provide an accurate and persistent view of identity to our customers. This allows you to maintain a consistent and comprehensive understanding of your customers and their marketing attributes over time.
- Highly accurate and refreshed digital identities: Our signal-agnostic graph is not reliant on any one signal as it includes HEMs, cookies, MAIDs, IPs, Universal IDs, and CTV IDs. Our Digital Graph is updated weekly, ensuring the data is always fresh and addressable. This persistent linkage of individuals and households to their identifiers and devices means your campaigns are always targeting the right people.
- Connected offline and digital graphs for holistic insights: We connect offline and digital identities by following privacy-first best practices, such as preventing re-identification, to allow insights from the offline world to be used in the online world. This integrated approach, enriched with marketing data, gives you better insights, more addressable advertising, and the ability to engage customers across multiple devices while accurately measuring campaign impact.
Transform challenges into opportunities
The rise of the multi-ID landscape presents both challenges and opportunities for the advertising industry. We stand as the trusted partner to navigate this complexity, utilizing insights from the offline world to inform decisions in the online world, enabling personalized marketing and accurate attribution, and helping you achieve your current and future goals.

After another week under the sun at Cannes Lions 2025, one thing is abundantly clear: our industry is done talking about possibilities — it’s ready to act. From speaking engagements to packed suite meetings, and even stateside through our “Can’t Cannes” activations, the appetite for change was real — and we were right at the center of it. A front-row seat to innovation Experian made a powerful impact across the Croisette, partnering with Audiostack, Basis, Infillion, IQVIA, Magnite, NextRoll, Odeeo, OpenX, The Female Quotient, and the Unplugged Collective x The Digital Marketer, to contribute to some of the week’s most insightful conversations. Our thought leaders were everywhere—on stage, in studio interviews, at executive roundtables—offering a clear voice on retail media growth, pharma advertising disruption, AI innovation, and identity-driven personalization. Three themes that defined the week 1. AI gets real If 2024 was the year of AI buzz, then 2025 is the year AI found its footing. Conversations shifted from “what if” to “what now.” While the promise of AI was front and center, conversations with clients and partners highlighted that we’re still in the foundational phase. Real-world applications—from creative optimization to predictive segmentation—are gaining traction, but long-term value will depend on robust data architecture and trustworthy identity frameworks. MiQ and PMG debuted AI-integrated platforms that demonstrated how AI can automate creative, optimize budget allocation, and personalize media in real time. AI has moved from sidekick to strategist. \”Last year it was all about AI, but in a very general sense. This year, it’s about specific applications — a clear sign AI is evolving from a talking point into product.”Budi Tanzi, VP, Product 2. Outcomes > impressions Outcomes may have been a buzzword at Cannes, but as several industry leaders pointed out, simply saying “we drive outcomes” isn’t enough—it risks sounding like table stakes. In today’s performance-driven environment, what matters is how companies define and deliver those outcomes in unique ways. The most compelling conversations weren’t about generic promises, but about clear strategies: challenging assumptions, leaning into strengths, and making specific choices that tie data, media, and technology to measurable impact. \”By using consistent identity across planning, activation, and measurement, marketers can connect ad exposure to real-world outcomes—whether that’s an online conversion, an in-store visit, or a new customer relationship.\”Chris Feo, Chief Business Officer 3. Curation isn\’t just a tactic Curation is quickly becoming the industry’s preferred approach to cutting through complexity. As marketers contend with signal loss and inconsistent inventory quality, the shift from broad access to intentional activation is gaining momentum. At Experian, we see curation not just as packaging, but as strategic alignment—where identity, data, and inventory come together in purpose-built environments that reduce waste, enhance safety, and drive performance. \”Supply-side data activation and optimization, aka “curation,” is an alternative to the traditional approach to data activation. Unlike the traditional DMP-to-DSP activation flow, curation allows buyers to leverage supply-path data more directly. The upshot? Improved performance and pricing for media agencies and brand advertisers.\”Drew Stein, Managing Director, Audigent Bringing the Cannes experience stateside Not everyone can make it to the South of France—so we brought Cannes to them. Our “Can’t Cannes” events in the U.S. offered local clients a first-class experience filled with insights and networking, minus the jet lag. Final takeaways This year’s festival made one thing clear: real progress requires more than innovation; it requires integration. And that’s where Experian is focused—connecting identity to activation, and data to outcomes, in ways that are practical, scalable, and privacy-resilient. If I had to sum it up? AI is progressing from abstract to application Curation beats clutter Partnership is power And everyone’s aligned around performance We’re grateful to have been part of these conversations and even more excited about where they’ll lead next. Let’s continue the conversation If you\’re exploring how to connect identity to performance, or simplify the way you activate, measure, and grow, we’d love to talk. Latest posts

Originally appeared in AdExchanger Google’s decision not to deprecate cookies in the Chrome browser after all caused a stir across the industry. Companies invested heavily in developing solutions aligned with the Privacy Sandbox as a survival tactic for the post-cookie landscape. At first glance, Google’s about-face may appear to undercut those efforts. It’s easy, and perhaps even satisfying for some – but inaccurate – to say “all that effort was for nothing.” Given Chrome’s dominance among browsers, AdTech companies had no choice but to prepare for “what if” scenarios. The same goes for cookie deprecation. Google’s plan to end support for third-party cookies would have removed a mechanism that has been a cornerstone of addressability for the past 15 years. To be clear, those efforts have not been wasted. They spurred innovation across the AdTech landscape, driving progress in privacy-first targeting, alternative identifiers, supply-path data activation, and real-time data enrichment – all of which will pay dividends for years to come. Whether born directly from Privacy Sandbox participation or inspired by the broader trend toward privacy reform, industry-wide preparation for cookie loss and browser disruption has yielded tangible benefits. Pressure from Google, Apple, and evolving regulations served as a catalyst for modernization that could shape the next decade of advertising technology. An industry anchored in product innovation AdTech is a fundamentally product-driven industry defined by short innovation cycles and the imperative to build and test rapidly. This DNA enables companies to stay resilient, evolve and deliver innovation. Change is good. Disruption can be even better – but only for those who embrace it. Google’s evolving stance on cookies and Privacy Sandbox doesn’t negate what’s been learned. If anything, it underscores the need to keep innovating. The next wave of disruption is likely right around the corner. The payoff While some may argue that the time and effort spent preparing for cookie loss was wasted, those efforts have functioned as a forcing mechanism for several innovations in data activation. Supply-side data activation and optimization, aka “curation,” is an alternative to the traditional approach to data activation. Unlike the traditional data management platform (DMP) to demand-side platform (DSP) activation flow, curation allows buyers to utilize supply-path data more directly. The upshot? Improved performance and pricing for media agencies and brand advertisers. As curation continues to evolve, it’s poised to play a central role in how advertisers and publishers transact. Real-time data enrichment is another area that has benefited from this period of accelerated innovation. Many companies were compelled to improve their tech stacks to align with Sandbox protocols. These updates, particularly in real-time data enrichment capabilities, are now laying the groundwork for future data activation strategies across both the buy and sell-sides. Exiting out of tunnel vision Over the past five years, the AdTech industry has invested deeply in planning for a future without cookies. Still those investments have been well worth it. While cookies are not going away, the broader deprecation of signal continues. The work that was done to prepare will inevitably inform the next evolution of our industry. Contact us Latest posts
