As commerce media reshapes digital advertising, the line between first- and third-party onboarding is blurring. Whether you’re activating data for your own campaigns or helping partners reach new audiences, how that data is used matters more than ever. This article explores what happens when first-party data becomes third-party, how the new environment changes activation, and how Experian helps brands navigate it all with privacy-led identity, efficient modeling, and seamless ecosystem connections.In this article…
In the past, first-party onboarding focused on activating a brand’s own customer data, while third-party onboarding allowed advertisers to tap into external audiences. But the rise of commerce media networks (CMNs) — which now influence over 14% of all digital ad spend — has blurred those once-clear lines.
CMNs, retail media ecosystems, and brand partnerships are reshaping how data is shared, accessed, and activated. Today, the question isn’t just who owns the data but why it’s being used. Whether to strengthen customer relationships or create new revenue opportunities, intent now shapes how data must be governed, shared, and measured.
For brands with strong first-party data, this shift creates opportunities to deliver more personalized, privacy-safe campaigns to their own audiences and to extend that data’s value by enabling partners to reach new segments.
In this connected ecosystem, data onboarding enables brands to activate, scale, and monetize their data responsibly, turning first-party insights into privacy-led growth opportunities. Trusted onboarding partners like Experian can help marketers activate first-party audiences with accuracy while scaling and connecting those audiences across the ecosystem for compliant, revenue-generating collaboration.
What is data onboarding?
Data onboarding moves offline consumer data — like CRM records, loyalty details, or transaction histories — into digital environments for activation and measurement. It connects real-world insight with digital engagement across display, social, search, connected TV (CTV), and commerce media. Data onboarding is now a strategic pillar for marketers managing signal loss, disconnected data, and rising privacy expectations.
The approach you take and who owns the data determine what kind of onboarding it is:
- First-party onboarding: A brand activates its own customer data across digital platforms.
- Third-party onboarding: A brand enables others to use its data, often monetizing it — common in CMNs or commerce media ecosystems.
Experian helps marketers succeed in both models. With AI-driven identity resolution, persistent identifiers, and privacy-first infrastructure, we make onboarding accurate, compliant, and scalable, regardless of who owns the data.
Why do marketers need data onboarding?
Even the most data-rich brands often have a limited view and reach when it comes to their audiences. They’re confined to the data they collect directly and to the owned channels they use to engage those people. Customer files may reveal who’s already in the ecosystem, but not always where those people spend time, how they behave across channels, or why they make certain decisions.
Onboarding bridges that gap. It transforms offline data into digital activation power, allowing marketers to connect insight with action. Experian makes this possible at scale with trusted identity resolution, data ranked #1 in accuracy by Truthset, audience modeling expertise, and seamless data integration across platforms, helping marketers activate confidently and compliantly.
With Experian’s onboarding solutions, marketers can achieve:
- Unified customer identity across devices, channels, and touchpoints.
- Cross-channel personalization with consistent, relevant messaging wherever customers engage.
- Scaled, privacy-compliant reach beyond owned channels without sacrificing control or consent.
- Better insights and audience creation by blending first-party and Experian Marketing Data for a deeper understanding.
- Cross-channel activation with deep integrations into the advertising ecosystem.
Core steps in the onboarding process
While onboarding can vary across use cases, the core process remains consistent. Experian’s AI-enhanced identity infrastructure streamlines every stage of data migration and activation, making each step safer and faster:
- Data ingestion: Transfer the data into the onboarding environment using privacy-safe encryption and consented parameters to protect sensitive information responsibly from the start.
- Transformation: Cleanse, standardize, and format records to align with digital identifiers. This eliminates inconsistencies and makes every record easier to recognize and activate later.
- Identity resolution: Link offline identifiers (names, emails, addresses) to hashed digital equivalents like mobile advertising IDs (MAIDs), CTV IDs, and universal IDs via Experian’s Offline and Digital Graphs. Identity resolution connects customers to their digital presence without exposing personal information.
- Identity matching: Match hashed emails, MAIDs, and device-graph identifiers to activation partners for each audience across demand-side platforms (DSPs), social, and CTV platforms. This expands your audience reach while maintaining accuracy and privacy.
- Activation: Deliver privacy-safe audiences to DSPs, social, search, or CMN shelves from third-party data providers (not the CMN’s own data) — or directly to an advertiser’s seat for immediate activation. You’ll turn insights into action and be able to reach the right people with relevant, compliant messaging.
Behind this flow is Experian’s identity graph, which links 250 million U.S. individuals, 900 million hashed emails, and 4.2 billion digital identifiers refreshed weekly. It’s the foundation that keeps onboarding accurate as the signal landscape shifts.
First-party vs. third-party onboarding
Every digital marketing data point has a story, but whose story it tells depends on who’s using it. That distinction defines the difference between first-party and third-party onboarding. Both are essential to modern marketing, but they carry different expectations for control, consent, and accountability.
First-party onboarding: Activate your own data safely and strategically
First-party onboarding starts with the data a brand earns directly from its own customers through trusted relationships. This data belongs to the brand, as customers have given consent, and the brand has the responsibility (and opportunity) to use it well.
That data might include:
- CRM records
- Loyalty-program data
- Purchase or transaction histories
- Website or app interactions
- Email subscribers or reward members
How first-party onboarding works in practice
The onboarding process connects this offline data to digital identity so marketers can reach their existing customers across channels.
For example, a credit card company might take its CRM file of cardholders, hash the email addresses, and upload that file to a DSP via Experian’s Audience Engine. Experian’s identity graph resolves those emails to privacy-safe digital identifiers like MAIDs, CTV IDs, or universal IDs. The result is a ready-to-activate audience that can be reached on CTV, social, and display without exposing raw personally identifiable information (PII).
Why control matters in first-party onboarding
The advantage of first-party onboarding is control; the brand decides what to share and how to use it. It’s a powerful way to:
- Personalize messages for known customers
- Re-engage lapsed buyers or loyalty members
- Suppress existing customers from prospecting campaigns
- Measure performance with closed-loop attribution
Doing first-party onboarding responsibly
That control comes with responsibility. Even consented customer data that has been consented to can pose risks if handled carelessly or shared with unverified partners. Experian’s First-Party Onboarding sits on a privacy-first identity foundation, governed by decades of compliance leadership under laws like the Gramm-Leach-Bliley Act (GLBA) and Fair Credit Reporting Act (FCRA).
We connect data and identity responsibly, so marketers can activate with confidence while protecting consumers.
Why first-party onboarding matters
First-party onboarding is the cornerstone of responsible marketing. It allows brands to deepen relationships they already have, using data that customers have freely shared. And with Experian’s secure First-Party Onboarding, that data stays encrypted, compliant, and under the brand’s control from start to finish.
Third-party onboarding: Share and monetize data responsibly
Third-party onboarding begins when a brand allows someone else to use its data. It’s how data providers, publishers, and especially CMNs monetize their audiences — turning first-party customer insights into addressable, privacy-safe segments that advertisers can buy and activate across digital channels.
How third-party onboarding works in practice
Think of it as data collaboration at scale. Let’s say a retailer collects first-party shopper data like product purchases, loyalty card usage, and store visits. Then, they partner with Experian to make that audience available to outside advertisers, such as a consumer packaged goods (CPG) brand.
Through Experian Third-Party Onboarding, those audiences are resolved, privacy-protected, and distributed to integrated destinations such as The Trade Desk, Magnite, or NBCUniversal for activation.
- To the retailer, it’s their first-party data.
- To the CPG, it’s third-party data they can use for targeted campaigns.
- To Experian, it’s an opportunity to ensure the entire exchange is accurate and compliant.
Why scale matters in third-party onboarding
The benefit of third-party onboarding is scale. It enables data owners to monetize their insights, while giving advertisers access to richer audiences they couldn’t build on their own. It’s the engine behind CMNs, commerce media, and the growing data-sharing economy.
With a partner like Experian, that scale becomes even more powerful. Our advanced modeling and identity solutions help brands expand their audiences responsibly using lookalike and predictive modeling to identify high-value segments, increase reach, and maximize performance across every activation channel.
The responsibilities of data sharing in third-party onboarding
As data ecosystems grow, so does the opportunity to collaborate responsibly. Once data leaves its original owner’s ecosystem:
- Consent obligations become more complex.
- Control over downstream usage can blur.
- Regulatory oversight increases, especially around transparency and consumer rights.
With the right governance in place, these responsibilities can help strengthen partnerships, protect consumers, and create a foundation for sustainable growth.
Experian’s ethical enablement role in third-party onboarding
Experian’s enablement role is both technical and ethical. Our deep expertise enables us to partner with brands and support their monetization efforts, helping them derive new value from their data while maintaining the highest standards of privacy and compliance. Meanwhile, our infrastructure ensures third-party data onboarding happens securely and transparently:
- Identity resolution expands reach without overexposing identifiers.
- Data verification and governance ensure partners meet strict privacy standards.
- Revenue-share structures maintain fairness without hidden costs.
- Cross-channel integrations enable you to onboard your data once and activate it everywhere (programmatic, CTV, or social) through Experian’s 30+ direct and 200+ indirect destination partnerships.
Why third-party onboarding matters
Third-party onboarding is the foundation of modern data collaboration. When done through Experian, it becomes a trusted extension of your brand’s identity governed by the same privacy, consent, and accuracy standards that strengthen your first-party ecosystem. We help brands uncover new opportunities for growth, partnership, and responsible innovation.
When first-party onboarding turns into third-party onboarding
When data ownership shifts, privacy expectations change, and the rules of onboarding start to look a little different. This stage can feel complex, but with the right approach, the crossover becomes clear. It’s a natural evolution that helps brands connect data more effectively and collaborate confidently.
Here’s what that can look like in practice. A retailer uses its own first-party data to engage loyal shoppers through its website, app, or email program. The data is secure, consented, and fully under the retailer’s control. Then comes collaboration. The retailer decides to partner with a brand, like a CPG company, to reach those same shoppers across connected TV or the open web.
In that moment, the retailer’s first-party data becomes the CPG’s third-party data. Ownership doesn’t really change, but accountability does, along with new privacy and compliance considerations.
This “crossover moment,” when first-party onboarding turns into third-party activation, is a small shift with big potential that can lead to new reach, deepen collaboration, and strengthen customer connections across the marketing ecosystem when managed responsibly.
Why clarity matters in the crossover between first- and third-party onboarding
When data starts flowing beyond owned channels, questions naturally come up. Marketers want to know things like:
- Who “owns” the audience once it’s shared with a partner or DSP?
- Whose privacy notice applies — the retailer’s, the brand’s, or both?
- How do we keep match accuracy without overexposing PII?
- Who’s responsible for opt-outs and suppression compliance downstream?
These are the right questions to be asking, and they’re signs of a mature, data-driven strategy. Asking them is what helps brands strengthen governance, build trust, and get more value from collaboration. With the right framework in place, what could feel complicated becomes clear, opening the door to more confident growth across CMNs and other shared-data environments.
How Experian brings clarity and control to the first- and third-party onboarding crossover
As a neutral, privacy-first partner, we provide the infrastructure that keeps data secure, compliant, and meaningful wherever it flows. Our onboarding solutions help both sides of the partnership — retailers and advertisers — maintain trust through:

This is how Experian transforms complex data challenges into seamless, scalable collaborations that give marketers the confidence to expand responsibly into commerce media and commerce ecosystems.

- Enrich shopper data with Experian Marketing Attributes for deeper insights.
- Extend addressability off-site using privacy-safe identity resolution.

Data onboarding FAQs
Experian First-Party Onboarding helps brands take the customer data they already own, like CRM lists or loyalty files, and use it safely across digital channels for targeting, personalization, and measurement. Experian Third-Party Onboarding helps retailers, publishers, and data providers share or monetize their audiences responsibly with partners through secure, privacy-first activation.
Both are powered by Experian’s trusted identity foundation that keeps every connection accurate, compliant, and privacy-safe.
The difference between first- and third-party onboarding is who’s using the data. First-party means a brand is activating its own customer information, while third-party means that data is being shared or used by another advertiser or partner.
First-party onboarding becomes third-party onboarding most often in CMNs or commerce media. When a retailer monetizes its first-party shopper data for use by CPGs or advertisers, the use case shifts to third-party onboarding.
First-party onboarding helps brands reach and understand their existing customers, while third-party onboarding helps expand reach, enable partnerships, and monetize data responsibly.

Originally appeared in Streaming Media Magazine Navigating today’s fragmented, privacy-conscious media landscape is a bit like stepping into a dense jungle. The buy-side—marketers, agencies, and demand-side platforms (DSPs)—must find their way through signal loss, measurement challenges, and evolving consumer expectations. But this isn’t just a challenge; it’s a strategic opportunity. Let’s dive into how buy-side players can use Experian’s advanced data and identity solutions to be their guide through the jungle and emerge as winners. Marketers: Maintaining personalization and measurement across channels Marketers are navigating an increasingly fragmented media jungle, where the deprecation of signals like cookies, mobile ad IDs (MAIDs), and IP addresses makes finding and understanding audiences feel like guesswork. To chart a clear path, marketers need a reliable compass—and identity resolution provides exactly that. A strong identity provider, grounded in offline data like names, addresses, phone numbers, and emails, acts as a guide through the chaos. By connecting offline signals with digital identifiers in a privacy-first manner, marketers can uncover the relationships between households and devices, then enrich those profiles with valuable marketing data. With a complete view of your customers, you gain deeper insights and can seamlessly reach the right audience across channels—even as signals evolve. It’s a marketer’s North Star—constant, dependable, and always pointing you in the right direction. How Experian can help Imagine a financial services brand aiming to connect with high-net-worth individuals across today’s fragmented media world. They’ve excelled on social and search but now want to dive into connected TV (CTV) and other emerging channels. Enter Experian’s Digital Graph. By seamlessly connecting digital identifiers like MAIDs, CTV IDs and hashed emails (HEMs), our graph becomes the bridge that unifies their audience across every channel. Suddenly, the same audience that saw their ad on social during lunch is now watching a personalized spot on CTV that evening, all thanks to Experian. The result? A cohesive campaign that delivers hyper-relevant messages, stronger engagement, and measurable success. With Experian, fragmentation becomes connection, and personalization stays powerful across the entire media landscape. Agencies: Strategic partners in a fragmented world Agencies are the architects of the identity jungle, building bridges that guide brands through fragmentation and deliver campaign success. Thriving in this terrain requires data solutions that create actionable insights, enable personalization, and drive measurable outcomes. To meet marketers’ demands, many agencies have invested heavily—acquiring data companies or forging strategic partnerships to strengthen their foundations in data and identity solutions. These investments help them connect fragmented audience data and unlock new opportunities for their clients. But even with in-house capabilities, agencies often need more—more attributes, more integrations, and greater connectivity. In the jungle of identity, success isn’t just about building better data assets; it’s about ensuring those assets can be utilized across platforms. How Experian can help Picture a large independent agency ready to step up its game—expanding beyond its middle-market niche to attract enterprise-level clients. But to play in the big leagues, they need more than a solid strategy; they need data and identity solutions that deliver a competitive edge. Enter Experian. With our rich identity graph and deep customer insights, the agency can unlock new opportunities for its clients. Imagine offering enterprises the ability to connect fragmented audience data, create hyper-targeted campaigns, and measure success across every channel. The payoff? The agency doesn’t just win over new enterprise clients; it strengthens relationships with existing customers by proving it can navigate today’s fragmented media landscape with precision and measurable impact. With Experian, the agency becomes an indispensable strategic partner in the data-driven advertising world. DSPs: Navigating signal loss with a multi-ID strategy For DSPs, navigating the identity jungle means forging a path through the winding trails of cookieless strategies. With third-party cookies fading and no single identity solution—like Unified ID 2.0 (UID2)—able to cover all media engagement, DSPs must adapt to a multi-ID world. The challenge is twofold: finding flexible solutions to manage a multitude of identifiers while staying compliant with a growing number of state-level privacy laws. It’s not just a technical problem; it’s a call for strategic vision. And the way to thrive in this ever-changing terrain is to invest in identity solutions that connect digital and offline identifiers to a single customer profile. How Experian can help Imagine a DSP navigating a complex web of identifiers—UID2, HEMs, proprietary IDs—while juggling compliance with evolving privacy laws. Experian steps in as the ultimate connector. Our identity solutions, powered by stable offline data, are signal-agnostic and integrated across the advertising ecosystem. This ensures that DSPs can confidently manage multiple identity frameworks, keeping campaigns targeted, measurable, and compliant. With Experian, DSPs gain more than a stopgap solution; they get a future-proof identity strategy. The result? Better targeting, smoother omnichannel execution, and the strategic edge needed to thrive in a fragmented, multi-ID world. Turning identity challenges into a strategic advantage The identity jungle is a thriving ecosystem for those with the right guide. Experian helps marketers, agencies, and DSPs chart the course by unifying multiple identifiers into a single, complete customer profile. With the right tools (and a good map), buy-side stakeholders can learn more about their customer, reach audiences across channels, and deliver personalized marketing.

We spoke with industry leaders from Ampersand, Basis Technologies, Captify, Cuebiq, CvE, Fetch, Madhive, MiQ, and Samsung to gather insights on how innovations in data and identity are creating stronger consumer connections. Here are five key insights to consider. 1. Build on trust with first-party data Stricter privacy regulations and growing customer expectations mean businesses must rethink how they gather and use data. A robust first-party data strategy centers on gathering high-quality data, such as behavioral and transactional data. By using behavioral, lifestyle, and purchasing data, brands can craft personalized strategies that align with their goals. This approach balances effective targeting with building trust and complying with privacy rules. Integrating identity solutions like Unified I.D. 2.0 (UID2) and ID5 into existing data strategies improves interoperability across platforms while keeping user privacy intact. These tools help create more effective campaigns. "We've been preparing and leaning into educating our clients around the value of first-party data. These are very important and primary considerations in any of our campaigns."April Weeks, Basis Technologies 2. Align metrics with business goals To demonstrate clear value, campaigns need to tie their outcomes to broader goals. Relying only on click-through rates or CPMs won’t cut it. Metrics that measure meaningful results, like driving sales or increasing customer retention, provide greater transparency than surface level data, like clicks or impressions. A continuous feedback loop between targeting and measurement ensures campaigns can be refined to better align with business objectives. This feedback helps marketers understand who they are targeting and how those audiences are driving key business results. Shifting focus to metrics that resonate with stakeholders ensures that marketing efforts are evaluated based on their true contribution to the company's objectives. "The television industry has access to more data than ever before, and at Samsung Ads, our ACR technology helps us provide valuable insights about what content and ads are being viewed. This abundance of data enables us to support clients in aligning their campaigns with business objectives effectively."Justin Evans, Samsung Ads 3. Personalize experiences to boost engagement Personalization drives stronger customer relationships by delivering tailored experiences to individual customer needs. Using data-driven insights to fine-tune offers and messaging makes interactions more relevant, strengthening brand loyalty. Combining behavioral, lifestyle, and transactional data provides a comprehensive understanding of the customer journey and ensures each touchpoint feels personal. Testing and iterating on personalization strategies also helps identify which data and approaches yield the best results. Scaling these efforts means customers receive the right messaging at the right time, and businesses see better outcomes. "Every business should be building a data strategy that thinks about the different versions of data that exist and how they bring that together. They don't necessarily need to own all of it but have a clear rationale and strategy about where you're using which data sets."Paul Frampton, CvE 4. Utilize advanced measurement tools for smarter decisions Improving the effectiveness of campaigns starts with using sophisticated measurement tools to gain actionable insights. Using analytics like brand lift studies, foot traffic analysis, app download tracking, incrementality, and share of search allows marketers to understand the full impact of their efforts. With these resources, teams can pinpoint what’s working, make real-time adjustments, and refine their approach. This adaptability ensures budgets are used as effectively as possible. Learn how Swiss Sense measured marketing outcomes using Mosaic® "We are playing a leading role in democratizing new tools for local advertisers. By mimicking the marketing funnel mentality, we've introduced solutions ranging from measuring brand lift to tracking foot traffic and app downloads."Luc Dumont, Madhive 5. Adapt quickly to stay competitive The only constant in advertising is change. Adapting quickly to new technologies and consumer behaviors keeps businesses competitive. A culture of agility fosters innovation, making it easier to respond to industry shifts and discover new opportunities. Companies that anticipate change and invest in modern data solutions position themselves for long-term growth. Whether it’s adjusting to privacy updates, exploring emerging tech, or staying flexible, businesses must continuously invest in adapting their platforms and strategies. "Falling behind is not really an option. There's always a change in advertising and in data where there's a new horizon. The people who stay close to that and innovate will always follow it."Amelia Waddington, Captify Shaping the future Building meaningful consumer connections requires advertisers to combine robust data strategies with flexibility and innovation. By focusing on these five considerations, marketers can adapt to today’s challenges while preparing for what’s ahead. Connect with our experts Latest posts
