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.

Originally appeared in Adweek This holiday advertising season, identity is the real differentiator Marketers are betting big on AI to run their holiday advertising, using it to build predictive audiences, generate creative at scale, and optimize media buys in real time. The draw is clear: greater efficiency, delivered at scale. But here’s the problem: without a solid identity foundation, AI is just guessing. And in a year when consumers are cautious and competition is fierce, guesses won’t deliver the outcomes you need. Experian’s 2025 Holiday spending trends and insights report shows that success this season will depend on connecting the right data to the right audiences in real time. Download the report now Are shoppers really using AI to make holiday purchases? Not yet. Only 12% of consumers plan to use AI tools to shop this season, mostly for finding discounts. Instead, trusted influences (like retailer websites, product reviews, and recommendations) still guide buying decisions. For marketers, that’s a signal to focus on credibility and connection. AI can support your holiday advertising strategy, but trust still wins the sale. Consumer sentiment heading into the holidays is low, but that could mislead marketers Here\’s why How marketers are really using AI in holiday advertising Behind the scenes, AI is working overtime. Teams use it to segment audiences, test creative, and optimize media in real time. These capabilities are powerful, but only if they’re grounded in accurate, persistent data. Think about the typical holiday shopper. They may browse a product online, validate it in store, and finally purchase days later from a different device than they used while browsing. If AI isn’t anchored in identity, it struggles to connect those touchpoints. Instead of amplifying relevance, it amplifies noise. See our predictions for Black Friday 2025 Why identity is the GPS for AI-driven holiday advertising Identity is what turns AI from a blunt instrument into an accurate tool. By unifying fragmented signals across channels and devices, identity provides the consistent consumer view that AI needs to be effective. With that foundation, AI can do more than churn out models. Instead, it can: Identify the right audiences and filter out waste Personalize with context, not just scale Measure real outcomes, linking exposures to visits and purchases Identity doesn’t just improve efficiency; it creates accountability. And in a season where every holiday advertising campaign dollar is scrutinized, accountability is the difference between investment and waste. Why connected data will make or break Cyber Week How to turn complexity into clarity this holiday season This year\’s holiday advertising season is complicated. Marketers are confident, consumers are cautious, and AI is somewhere in the middle. The challenge isn’t just speed or volume, it’s accuracy. By pairing AI with identity, you can adapt to real behavior instead of assumptions. You can build campaigns that are consistent across connected TV, retail media, and social platforms. And you can prove results when it matters most. AI isn’t a holiday miracle. But when it’s powered by identity, it can give you clarity in a noisy season and proof of performance when budgets are under scrutiny. Explore Experian\’s holiday audiences to activate this season What’s the real takeaway for marketers this season? Don’t assume AI alone will save your holiday advertising strategy. It won’t. Consumers still trust human voices more than machines, and your AI models are only as strong as the data beneath them. Identity is the difference between guesswork and accuracy, between activity and impact. This holiday season, the winners won’t be the brands that simply spend more or automate faster. They’ll be the ones that put identity at the core of their AI strategy and meet consumers where they really are. Download Experian’s 2025 Holiday spending trends and insights report to see where consumers are spending and how identity can help your holiday advertising campaigns more effective. Download now FAQs Why isn’t AI enough on its own for holiday advertising? AI works best when it’s grounded in accurate data. Without identity, it can’t connect actions across devices or channels, which limits its effectiveness. How does identity improve AI-driven campaigns? Identity creates a single, persistent view of your audience. That means AI can personalize content, measure conversions, and cut waste with far greater accuracy. What does “identity” mean in marketing terms? It’s the data layer that connects people across their devices, browsers, and behaviors—so your campaigns reach real individuals. How can marketers prove ROI in holiday advertising? By tying exposure to verified outcomes—like store visits or purchases—using identity-linked data. That’s how Experian helps brands move from impressions to impact. Latest posts
