Brands are increasingly focused on offering personalized experiences while respecting consumer privacy. Addressability enables them to reach specific audiences with relevant messages, and personalization crafts unique content that aligns with each audience’s interests and needs. By combining these strategies, brands can create more relevant and effective marketing campaigns.
With new regulations and signal loss reshaping the landscape, alternative identifiers like the ID5 ID and The Trade Desk’s Unified I.D. 2.0 (UID2) are gaining importance. These tools give advertisers a more holistic view of consumers across channels, enhancing personalization and addressability even as traditional third-party cookies lose relevance.
To shed light on this topic, we interviewed experts from Audigent, Basis Technologies, CvE, ID5, MiQ and others. They shared insights on navigating privacy, utilizing new identifiers, and enhancing personalization with consent. Drawing from their perspectives, we’ve identified five considerations to help brands adapt and succeed in this evolving landscape.
1. Embrace a privacy-centric approach
With the increasing focus on consumer data protection, prioritizing privacy in your addressability efforts is essential. Implement strict data guidelines to protect personally identifiable information (PII) and maintain compliance with state-specific regulations.
To achieve this, empower consumers by providing clear and transparent choices about data sharing and honoring their preferences. Avoid targeting based on protected categories or sensitive information. By adopting a privacy-first mindset, you can build consumer trust while still delivering relevant advertising experiences.
“It’s important to champion consumer privacy and the free internet. We need to strike a balance between the two. This balance is essential for our jobs, the economy, news, politics, and all the valuable content and information we rely on.”
Drew Stein, Audigent
2. Personalize with consent
Consumers are more willing to share their information when they see clear benefits. In fact, over half of shoppers—and two-thirds of Gen X and Millennials—express a desire to receive holiday shopping deals directly from their preferred brands1. By offering value through loyalty programs, special offers, or interactive platforms, you can personalize experiences without compromising privacy.
To implement this strategy, encourage consumers to share their preferences and needs by being transparent and giving them control over their data. This approach builds trust, empowers your audience, and enhances personalization.
“Building personalization based on the data consumers have consented to share should lead to a positive experience that drives better engagement because it’s relevant to them.”
April Weeks, Basis Technologies
3. Personalize with contextual targeting
Contextual targeting involves delivering ads based on the content users are currently engaging with rather than user identifiers. By focusing on personalization through contextual targeting and dynamic content, you can align your strategies with your audience’s real needs and interests. This approach allows advertisers to reach consumers on websites with more visitors matching the demographics, behaviors, or interests they want to target.
“Personalization absolutely can thrive. We have various solutions, all utilizing IDs for targeting and personalization. Beyond that, we can also personalize using context, geo-contextual data, and creative strategies.”
Georgiana Haig, MiQ
4. Use alternative identifiers
As advertisers move beyond third-party cookies, exploring alternative identifiers offers reliable means to connect with consumers. Options like email addresses or device IDs provide direct connections, improving targeting accuracy.
Utilize identity graphs to link different signals and identifiers to establish strong ties to individual users or households. This approach maintains, and can even enhance, your ability to reach the right audience and measure campaign performance.
“It’s not just about maintaining addressability. It’s about massively improving addressability. When we run tests with some of our clients, they’re seeing 30, 40, 50, 60% incremental reach by using ID5 versus cookies.”
Mathieu Roche, ID5
5. Build partnerships
Navigating the complexities of addressability doesn’t have to be a solo effort. Partnerships between brands, publishers, and tech providers can lead to innovative solutions that benefit everyone.
Consider engaging in data partnerships to access new audience segments without maintaining extensive data. Collaborations focused on your tech stack can enhance your ability to deliver personalized content effectively and at scale.
“The rise of second-party data partnerships is going to be an interesting trend over the next couple of years. And if you need mass scale across the world, I think that’s a much more cost effective and scalable way to do it.”
Paul Frampton, CvE
Steering toward success
The future of addressability and personalization hinges on your ability to adapt to the changing privacy landscape while delivering meaningful, personalized experiences. By focusing on these five key considerations, you can navigate the complexities of modern advertising, build stronger relationships with consumers, and drive sustainable growth.

In our Ask the Expert Series, we interview leaders from our partner organizations who are helping lead their brands to new heights in AdTech. Today’s interview is with Ben Smith, VP of Product, Data Products at Infillion. Adapting to signal loss What does the Experian–Infillion integration mean for advertisers looking to reach audiences as signals fade? As cookies and mobile identifiers disappear, brands need a new way to find and reach their audiences. The Experian integration strengthens Infillion’s XGraph, a cookieless, interoperable identity graph that supports all major ID frameworks, unifying people and households across devices with privacy compliance, by providing a stronger identity foundation with household- and person-level data. This allows us to connect the dots deterministically and compliantly across devices and channels, including connected TV (CTV). The result is better match rates on your first-party data, more scalable reach in cookieless environments, and more effective frequency management across every screen. Connecting audiences across channels How does Experian’s Digital Graph strengthen Infillion’s ability to deliver addressable media across channels like CTV and mobile? Experian strengthens the household spine of XGraph, which means we can accurately connect CTV impressions to the people and devices in that home – then extend those connections to mobile and web. This lets us plan, activate, and measure campaigns at the right level: household for CTV, and person or device for mobile and web. The outcome is smarter reach, less waste from over-frequency, and campaigns that truly work together across channels. The value of earned attention Infillion has long championed “guaranteed attention” in advertising. How does that philosophy translate into measurable outcomes for brands? Our engagement formats, such as TrueX, are based on a simple principle: attention should be earned, not forced. Viewers choose to engage with the ad and complete an action, which means every impression represents real, voluntary attention rather than passive exposure. Because of that, we consistently see stronger completion rates, deeper engagement, and clearer downstream results – like lower acquisition costs, improved on-site behavior, and measurable brand lift. To take that a step further, we measure attention through UpLift, our real-time brand lift tool. UpLift helps quantify how exposure to a campaign influences awareness, consideration, or purchase intent, providing a more complete picture of how earned attention translates into business impact. Creative innovation and location insights Beyond identity resolution, what are some of Infillion’s capabilities, like advanced creative formats or location-based insights, that set you apart in the market? One key area is location intelligence, which combines privacy-safe geospatial insights with location-based targeting through our proprietary geofencing technology. This allows us to build custom, data-driven campaigns that connect media exposure to real-world outcomes – like store visits and dwell time – measured through Arrival, our in-house footfall attribution product. We also build custom audiences using a mix of zero-party survey data, first-party location-based segments, and bespoke audience builds aligned to each advertiser’s specific strategy. Then there’s creative innovation, which is a major differentiator for us. Our high-impact formats go beyond static display, such as interactive video units that let viewers explore products through hotspots or carousels, rich-media ads that feature polls, quizzes, dynamic distance, or gamified elements, and immersive experiences that encourage active participation rather than passive viewing. These creative formats not only capture attention but also generate deeper engagement and stronger performance for a variety of KPIs. Future ready media strategies How does Infillion’s ID-agnostic approach help brands future-proof their media strategies amid ongoing privacy and tech changes? We don’t put all our eggs in one basket. XGraph securely unifies multiple durable identifiers alongside our proprietary TrueX supply to strengthen CTV household reach. This agnostic design allows us to adapt as platforms, regulations, and browsers evolve – so you can preserve reach and measurement capabilities without getting locked into a single ID or losing coverage when the next signal deprecates. Raising the bar for media accountability Looking ahead, how is Infillion evolving its platform to meet the next wave of challenges in audience engagement and media accountability? From an engagement standpoint, we’re expanding our ability to support the full customer journey, offering ad experiences that move seamlessly from awareness to consideration to conversion. That includes smarter creative that adapts to context, intelligent targeting and retargeting informed by real data, and formats designed to drive measurable outcomes rather than just impressions. When it comes to accountability, we’re ensuring that measurement is both flexible and credible. In addition to our proprietary tools, we partner with leading third-party measurement providers to validate results and give advertisers confidence that their investment is truly performing. Within our DSP, we emphasize full transparency and log-level data access, ensuring advertisers can see exactly what’s happening on every impression. All of this builds toward the next era of agentic media buying – one enabled by our MCP suite and modular, component-based tools. This evolution brings greater accountability and next-generation audience engagement to an increasingly automated, intelligent media landscape. Our goal is to help brands connect more meaningfully with audiences while holding every impression – and every outcome – to a higher standard of transparency and effectiveness. Driving impact across the funnel What is a success story or use cases that demonstrate the impact of the Experian–Infillion integration? We recently partnered with a national veterans’ organization to raise awareness of its programs for injured or ill veterans and their families. Using the Experian integration, we combined persistent household- and person-level identifiers with cross-device activation to reach veteran and donor audiences more precisely across CTV, display, and rich media. The campaign achieved standout results – industry-leading engagement rates, a 99% video completion rate, and measurable lifts in both brand awareness (3.6 % increase) and donation consideration (13.7% lift). It’s a clear example of how stronger identity and smarter activation can drive meaningful outcomes across the full funnel. Contact us Identity resolution FAQs Why is identity resolution critical for CTV and cross-channel campaigns? Identity resolution ensures accurate connections between devices, households, and individuals. Experian's Offline Identity Resolution and Digital Graph strengthen these connections for improved targeting and consistent measurement across CTV, mobile, and web. What strategies help address the loss of cookies and mobile IDs? Solutions like Experian's Digital Graph enable brands to connect first-party data to household and person-level identifiers, ensuring scalable reach and compliant audience targeting legacy signals fade. How can engagement translate into measurable results? Focusing on earned attention (where audiences actively choose to engage) leads to stronger completion rates, improves on-site behavior, and drives measurable increases in brand awareness and consideration. What makes cross-channel targeting more effective? By linking CTV impressions to households and extending those connections to mobile and web, Experian's identity solutions ensure campaigns work together seamlessly, reducing over-frequency and improving overall reach.
