Connected TV political advertising in 2024

Published: May 7, 2024 by Experian Marketing Services

The impact of connected TV on 2024 political ads

Political advertising has advanced significantly in recent decades. Historically, campaigns had limited options for where they could advertise, and those channels had limited inventory. Political campaigns primarily relied on radio, print, and linear TV to reach voters, using mass marketing strategies to appeal broadly to unspecified audiences. These mediums had limited targeting capabilities and provided few data insights. However, this has all changed thanks to the rise of technology and changing media consumption habits.

With the advent of the internet and the emergence of various digital channels, political campaigns now have more inventory and options for getting their message out there, including connected TV (CTV) —a subset of advanced TV that has become a predominant channel for digital ad spend. CTV is the fastest-growing medium for political ads, with the upcoming 2024 election expected to see $1.5 billion in CTV marketing ad spend (nearly half of all political digital advertising dollars!). CTV’s share of political ad spending is set to jump from 2.7% in 2020 to 12.8% this year. The Harris campaign is leading the charge, allocating $200 million for digital ads, much of which will go to streaming platforms.

CTV advertising promises to be an effective method for political campaigns trying to reach voters with personalized content in 2024. Let’s look at CTV political ads a little closer and overview the implications for your political campaign.

The growth of CTV in political advertising

CTV has become central to political ad strategies in helping campaigns gain exposure through targeted, personalized ad experiences to specific audience segments based on demographics, behaviors, and interests. With CTV advertising, political campaigns have become more adaptable to changing viewer preferences and can ensure their messages resonate with diverse audiences across digital platforms. This strategy represents a critical opportunity for political campaigns to tap into the growing viewership of streaming and adjust their marketing plans to meet voters where they spend their time.

Although traditional broadcast TV remains at the forefront of political advertising, recent increases in CTV political ad spending in 2024 reflect shifting media consumption preferences toward streaming services. Today, the average American adult spends almost 2 hours per day on CTV devices. It’s worth noting that CTV has the most significant audience share with Millennials, which makes CTV an especially worthy investment for targeting the younger generations whose voting habits aren’t as established yet.

2024 political ad spending

Compared to the previous U.S. presidential election year in 2020, campaigns and interest groups are expected to increase their political ad spending promoting causes and candidates by almost a third in 2024, totaling approximately $12.32 billion, according to Reuters. This is said to encompass all advertising for federal, state, and local politics, including lobbying and election activities.

While traditional media still dominates political ad spending, digital platforms are growing, with 45% of digital ad spending projected to be allocated to CTV for its refined targeting capabilities and increased inventory in this election cycle. For reference, only 19% of digital political ad spend went to CTV in 2020.

While the presidential election tends to garner the most attention among voters, it’s essential to note that political ad spending goes well beyond the big race; over 500 seats are up for election in 2024. Down-ballot races and issues in state and local elections will significantly impact where ad dollars are allocated.

Experian’s relevant ballot initiative audiences

If you’re looking to reach voters based on their attitudes and behaviors around crucial ballot measures, Experian offers over 240 politically relevant audiences that can help. Our consumer behavior and interest audiences can fine-tune your targeting for local and national ballot initiatives if, for example, you were targeting military families who favor initiatives supporting veterans or households with children interested in supporting school funding. This precise targeting ensures your political ads reach the most receptive audiences and maximizes the impact of your ad spend.

Third-party cookie deprecation and CTV

The phase-out of third-party cookies has created a challenge for political campaigns relying on digital advertising strategies. In the past, political advertisers have used cookies to track a user’s web activity to understand their browsing behaviors across sites and create detailed profiles for targeting purposes. However, due to recent changes in online privacy regulations, third-party cookies are going away.

Political advertisers have recognized the need for innovation and are exploring new avenues for effectively reaching target audiences without third-party cookies. CTV has arisen as a promising solution, as it doesn’t rely on these cookies to paint a picture of audiences and offers an alternative for precise, privacy-compliant targeting and ad spend optimization. CTV publishers tend to know quite a bit about audiences, including their viewing habits, location, preferred CTV devices, and more —and utilizing this information can give your campaign deeper, more accurate data without invading user privacy.

Benefits of CTV over traditional TV advertising for political campaigns

CTV political ads are a great way to familiarize a candidate’s core audiences with their message and engage them with the campaign. Here are some specific ways a political campaign can benefit from CTV in its advertising strategies.

Broadened access to data

Traditional broadcast and cable TV are a means of one-way communication. This means viewers consume broadcasted content without direct interaction or a feedback loop for tracking engagement and behavior data.

CTV solves the limitations of traditional TV by offering access to more data than linear TV using technology and internet connectivity to gather real-time insights. CTV data on audience interactions, preferences, demographics, behaviors, location, income, and more enable precise targeting and tailored messaging for more impactful campaigns. Furthermore, digital infrastructure enables CTV devices to track clicks, ad impressions, and conversions, which marketers can use to understand interests, viewing habits, and audience demographics more effectively. To sum it up, CTV broadens the scope of data available for political campaigns to refine their targeting.

Targeted, personalized ad experiences

With traditional TV advertising, marketers have historically had to rely on mass marketing strategies, broadcasting ads to a general audience and hoping to reach the right demographic segments. This imprecise approach limits a marketer’s control over who sees their ads and wastes time and money.

In contrast, CTV platforms can collect abundant data on viewer behavior, preferences, and demographics, helping advertisers precisely target audiences and reach groups most likely to benefit from the ads. With CTV, advertisers can segment audiences based on gender, age, interests, location, and past viewing behavior. This level of granularity enables them to customize their messages to resonate with specific people and increase the relevance and effectiveness of their political ad campaigns. By delivering ads to the right groups of people at the right time, CTV helps advertisers maximize campaign impact and drive better results.

It’s worth noting that streaming viewership is beginning to change. Although younger generations have engaged the most with CTV, there is research to show that older generations are starting to help fuel its continued growth. Gen X and Baby Boomers have begun to embrace streaming and seek out ad-supported services to ad-free alternatives. These gradual shifts in behavior highlight the importance of understanding streaming generations to reach target audiences effectively.

Real-time ad campaign optimization

While traditional TV relies on fixed ad placements, CTV offers programmatic buying, which refers to buying and selling ad placements on CTV through automated technology. Programmatic CTV advertising is highly data-driven, which gives advertisers flexibility in their messaging strategies, helps them refine their targeting, and deliver relevant ads to the right people at the right time. With real-time analytics, campaigns can monitor ad performance, adapt to changing circumstances, and make data-driven decisions to maximize advertising impact and budget efficiency leading up to the election.

Challenges and considerations for advertisers

Despite how widely beneficial CTV advertising can be for political campaigns, marketers also need to be aware of its limitations.

Navigating ad fraud

Ad fraud is a major problem for unsuspecting advertisers. CTV ad fraud involves fake CTV devices or bots mimicking viewership and cheating marketers into paying for unviewed or non-existent ad placements. According to DoubleVerify’s Global Insights, CTV bot fraud increased nearly 70% in 2022 compared to the previous year, with CTV fraud instances tripling since 2020. In 2023, digital ad fraud cost the marketing industry $84 billion. These ad fraud schemes are rising due to the high CPM of CTV ads, leading to a bigger payout for fraudsters who steal ad dollars.

One of the primary challenges is the need for better technological safeguards to detect and mitigate illegitimate traffic, such as bot activity. Political advertisers often rely on third-party ad fraud and verification technologies to avoid falling victim, but these solutions cannot guarantee complete protection. This usually leaves advertisers unaware of fraudulent activities until they’ve already incurred financial losses.

As political campaigns increasingly embrace CTV political ads, they become bigger targets for fraud and must make protection and measurement central to validating their campaign efficacy in conjunction with robust fraud detection measures. These efforts can help protect the integrity of political ad campaigns, mitigate fraud, and ensure messaging reaches genuine voters.

Ensuring ad effectiveness

Measurement and attribution of CTV political ads can be challenging. CTV offers better insights into audience preferences and behavior than linear TV, but despite the existing measurement tools, CTV is fragmented, involves many platforms, and lacks standardized metrics and attribution models tailored to political campaign goals. These problems make it hard to compare campaign performance, track CTV users across their viewing experience, and ensure ads appear in the right environments.

To fully understand your ad effectiveness, you should ensure accurate tracking mechanisms of audience behaviors with individual ads to assess the impact of CTV campaigns on voter engagement and turnout. This will help you better understand how to achieve campaign objectives, where to focus your efforts, and how to appeal to viewers in future campaigns.

It may also be helpful to understand some of the metrics advertisers currently employ for CTV measurement, including completion rate and return on ad spend (ROAS). Because CTV ads often can’t be skipped, this advertising strategy has a high completion rate, sometimes nearing 90%. ROAS is more focused on what you get in return for your ads, allowing you to track profits per dollar spent on ads. Political marketers can also use metrics like campaign impressions, total reach, view-through rate, and cost per completed view to understand how their ads are performing.

Ethical considerations related to transparency and misinformation

Political advertisers are responsible for upholding transparency and accuracy in their messaging to build trust with voters. Given how polarized the current political climate is, misinformation could make or break a political campaign. Whether intentional or unintentional, spreading misinformation through CTV can undermine the democratic process and erode public confidence in political institutions. Political marketers must do their best to prioritize ethical conduct, adhere to regulatory guidelines, and ensure their ads convey truthful information to voters.

Looking ahead: CTV in the 2024 elections

The current election cycle promises record-breaking political ad spending in 2024 and will underscore CTV’s role in shaping the future of political communication and engagement. With shifting viewer preferences and the ongoing evolution of digital media consumption habits, political campaigns need to look at CTV as a critical platform for voter engagement so they can allocate resources and shift their strategy to harness its full potential.

Using the targeted capabilities and expansive reach CTV advertising offers, political entities can optimize ad creative for the streaming environment, implement data-driven targeting strategies, and effectively connect with voters across diverse demographics and geographic regions.

Why context is key to making AI successful in marketing

Personalization without context misses the moment Marketers have spent years perfecting personalization — but personalization alone often misses the mark. We’ve all seen it. You shop for a weekend getaway, then get served travel ads weeks later when you’re already home. The data was right. The timing wasn’t. Personalization based only on identity and behavior knows who you are but not when or why you’re ready to act. At Experian, we believe AI should make marketing feel more human. That means understanding people in context, recognizing their environment, mindset, and the moment, to create relevance that feels timely, not intrusive. The context gap: Why identity and behavior aren’t enough Identity and behavioral data can reveal the kind of consumer someone is and the kind of products they may want to buy. But they don’t explain what’s happening right now. The missing layer is context: the dynamic, real-time signal that shows why this moment matters. Context bridges the gap between knowing something about a consumer and understanding their intent. In an era of fragmented signals and stricter privacy rules, context is one of the most reliable ways to stay relevant without over-reliance on personal identifiers. It helps marketers adapt to shifting needs while keeping privacy intact. How Experian interprets context in real-time By context, we mean all the subtle, in-the-moment signals, like time of day, location, or what someone’s watching, that shape what people care about in real-time. At Experian, our technology interprets these in real-time: Temporal signals Time-based patterns such as daypart (morning vs. evening), recency (how fresh a signal is), seasonality (holidays, life events), and micro-moments (split-second intent-driven actions). Environmental signals The media or content environment; what type of program, article, or channel someone is engaging with when they see your ad. Situational intent Signals like browsing behavior or purchase patterns that hint at a person’s stage in the buying journey, from early research to final decision. By layering these signals over verified identity and behavioral data, Experian’s AI-powered technology helps marketers predict not just who will act, but when they’re ready to act. Experian’s approach: Turning context into relevance Consumer behavior changes by the minute, and marketers need to adapt just as quickly. Our technology interprets live bidstream data, device activity, content, and timing to optimize in the moment, ensuring your campaigns deliver meaningful relevance, not just broader reach. Our process combines: Input Clean, accurate identity and audience data anchored in our privacy-first framework. Enrichment Our models fuse household, device, and publisher context to reveal moment-based intent. Activation We're investing in agentic workflows that help marketers plan and execute performance campaigns at scale, activated via our real-time technology that dynamically adjusts deals and surfaces contextually aligned opportunities. Governance Every signal and recommendation follows Experian’s principles of transparency, consent, and ethical oversight. We call this AI-powered simplicity tools that help marketers work more efficiently, with intelligence that feels intuitive and human-centered. How context changes the game for marketers AI without real-time context can only react based on what it already knows. AI-powered by in-the-moment contextual data points enables marketers to anticipate, not just react. A travel brand can shift creative from “dreaming” to “booking” mode when AI detects signals of active planning. A retailer can align promotions with trending content or regional weather shifts in real time. A CPG brand can trigger different product messages based on the context of recipes or household occasions. Adjustments based on contextual signals compound into meaningful gains — higher engagement, better efficiency, and a consumer experience that feels natural rather than intrusive. Context makes AI more human Context introduces empathy into automation. It’s what keeps AI from overstepping, ensuring the message fits the moment. When marketers respect timing, environment, and intent, ads feel like service, not surveillance. Context transforms relevance into respect. At Experian, our vision is to make every signal serve people, not profiles. Because the more our technology (including our AI tools and capabilities) understands context, the more human marketing becomes. At Experian, responsible intelligence is built in Every contextual model we deploy adheres to our standards for transparent and responsible innovation. We validate inputs, monitor model drift, and ensure no context-based variable introduces bias or privacy risk. This is what responsible automation looks like in practice: intelligent, explainable, and ethical. From who to when: Context is the future of AI-driven marketing Identity tells us who someone is. Context tells us when it matters. The next wave of AI-driven marketing will unite privacy-first identity with contextual intelligence to deliver real-time relevance, responsibly. At Experian, we’re building that future now. Our AI-driven capabilities bring identity, insight, and generative intelligence together so brands, agencies, and platforms can reach the right people, at the right moment, with relevance and respect.

FAQs How does context make AI-driven marketing more effective? Context makes AI-driven marketing more effective because it helps marketers understand people in context, recognizing their environment, mindset, and the moment, to create relevance that feels timely, not intrusive. Context helps marketers understand not just who a person is, but when and why they’re ready to act. Experian’s AI-powered technology layers contextual signals over verified identity data to deliver relevance that feels intuitive, not invasive.

Identity and behavioral data can reveal the kind of consumer someone is and the kind of products they may want to buy. But they don’t explain what’s happening right now. That’s the context gap—the missing link between knowing something about a consumer and understanding their intent.  Context closes this gap by analyzing environmental, temporal, and situational signals that reveal intent—without using invasive identifiers. Does Experian interpret contextual signals in real-time? Yes, at Experian, our technology interprets contextual signals, including temporal, environmental, and situational, in real-time. By layering these signals over Experian’s verified identity and behavioral data graph, marketers can predict when consumers are most receptive, turning data into real-time opportunity.

They forecast behaviors, fill gaps with inferred attributes, create lookalikes, and recommend next-best audiences so clients can anticipate opportunity.- AI-powered simplicity: We’re investing in generative AI and exploring emerging agentic workflows to reimagine how marketers work. Our vision is to move beyond basic audience recommendations toward intelligent audience discovery and automated setup, helping teams uncover opportunities they may not have considered, while spending less time on manual work and more time on strategy and outcomes.- Real-time intelligence: Consumer journeys never stand still.

Data onboarding for marketers: First-party vs. third-party in the era of CMNs

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.
