Retail media is quickly outpacing other areas of digital advertising and is projected to grow 29% by 2025. Despite this trajectory, retail media is still relatively new compared to traditional digital media and operates like a startup in terms of tech capabilities. Sustained growth will require retail media standardization — creating consistent ways to measure and compare ad performance across retail media networks (RMNs). This standardization will be key for RMNs wanting to understand what’s driving the most value and sales for their business.
In an Interactive Advertising Bureau (IAB) study, 62% of ad buyers pointed to standardization as a top growth challenge. The current ecosystem’s inconsistent standards have prevented effective investment in measurement and limited ad buyer participation. Standardization will be necessary moving forward for effective adoption and trust in these new channels.
This article explores the challenges marketers face without retail media standardization and the collaborative efforts needed to establish consistent measurement standards across the industry.
How much standardization currently exists?
Retail media standardization is limited industry-wide, with each RMN using its own metrics and definitions; what one network calls a “conversion” might be defined differently by another. Some retail companies also sell ad space within siloed, walled-garden shopping environments, which makes it difficult for advertisers to compare performance across platforms. As a result, the current landscape lends itself to inconsistency, campaign measurement complications, and an unclear view of return on investment (ROI) across RMNs.
This fragmentation stems from how retailers have historically developed and managed customer data platforms and e-commerce websites independently, causing disparities in the types and quality of customer data available and the technologies used to manage it. Each retailer uses a unique technology stack and customer experience strategies, which means data is collected, utilized, and integrated into advertising platforms differently.
Why is standardization important?
A 2023 State of Retail Media Survey highlighted the industry’s lack of standardization as a significant obstacle to growth. The Association of National Advertisers also found that advertisers can’t fully take advantage of their retail media investments because of inconsistent measurement practices. Standardized retail media measurement practices are critical for growth. By setting consistent measurement standards across different platforms, it becomes easier for various players to:
- Assess how ads are performing
- See which strategies work across RMNs
- Optimize ad spending
- Make informed decisions
- Extract more value from advertising budgets
Ultimately, standardized metrics are a must for improving transparency, strategic effectiveness, and ROI.
Who is promoting standardization?
We’re seeing a collective push for retail media standardization by several industry stakeholders wanting a more cohesive and effective advertising ecosystem. One of the most recent efforts came from the IAB and the Media Rating Council (MRC). These organizations collaborated with brands, agencies, and RMNs to develop new guidelines for standardized measurement practices and have given the ecosystem a proposed common language for retail media measurement.
These guidelines were released in January 2024 to provide a consistent framework for the following across retail media platforms:
- Audience measurement
- Reporting
- Incrementality
- Transparency
- Viewability
- Ad delivery
- In-store advertising
Microsoft Retail Media, an early adopter of the framework, has experienced greater data transparency, accuracy, privacy, and security, which has benefited advertisers and retailers and advanced Microsoft’s position as a retail media industry leader. Widespread adoption of these guidelines has the potential to drive innovation, attract more advertisers, strengthen collaboration, grow the industry, and improve the consumer experience.
The benefits of industry standardization
A standardized retail media framework for performance measurement can benefit advertisers, retailers, media agencies, and other stakeholders in the ecosystem. Here are some ways each entity stands to benefit.
Benefits for retailers
Standardization makes it easier for retailers to demonstrate their credibility and the value of their retail media program. With uniform measurement across channels and campaigns, they can provide clear, comparable data that reflects their impact, builds trust, and encourages advertiser investment. Better campaign management efficiency also reduces the operational burden, so retailers can focus on improving customer experiences and driving sales.
Experian’s Activity Feed helps you measure performance — and understand how ads impact shopping behavior — by providing you with ad exposures in one environment (web or connected TV) that you can connect to an action in another (in-store purchase). Learn more about Activity Feed and see it in action here.
Benefits for media agencies and marketers
With standardized metrics, advertisers and media agencies have an easy, reliable way to compare metrics and assess the effectiveness of various campaigns across RMNs. This “apples to apples” comparison helps them determine which channels are truly driving better ROI so they can effectively optimize spending.
Standardization also improves collaboration with retailers and leads to more effective campaigns. Consistent guidelines can help teams create, carry out, and optimize retail media strategies and easily compare platform effectiveness.
Benefits for industry stakeholders
Industry stakeholders like technology providers and regulatory bodies can greatly benefit from standardized retail media measurement practices. Consistent measurement provides a common framework that improves transparency and trust among parties. With reliable and comparable metrics, standardization helps everyone speak the same language when it comes to performance evaluation and decision-making. This uniformity facilitates smoother interactions and partnerships between the buy and sell sides, so it’s easier to negotiate and collaborate.
Strategies for implementing retail media standardization
Standardizing measurement will require industry-wide coordination around several strategies, as outlined in best practices frameworks from standardization proponents like IAB/MRC and the Albertson’s Media Collective.
Unify reporting and performance measurement
To address the lack of standardization in performance metrics, RMNs must adopt uniform definitions and calculation methodologies for key metrics. Unified reporting in retail media requires successful stakeholder collaboration to:
- Agree on critical KPIs and reporting metrics like impressions and conversion rates
- Adopt standardized data formats and reporting tools
- Educate stakeholders
- Ensure data quality and compliance
- Continuously improve based on industry feedback
The IAB/MRC framework provides a basis for standardizing metrics for media delivery and engagement, as well as sales and conversions. This consistency helps advertisers compare performance across platforms effectively, enhancing transparency and decision-making.
Standardize product specifications
It’s important for advertisers to have consistent product specifications, as it makes it easier to create and deploy ads across multiple RMNs. To achieve this, RMNs should align ad formats, file sizes, animations, and video specifications with IAB guidelines. Following these standards will help RMNs eliminate compatibility issues, simplify adoption, and save time and resources. It’s also vital for RMNs to maintain flexibility for unique ad formats in order to encourage innovation while still benefiting from standardized specifications.
Introduce third-party verification and disclose capabilities
Introducing third-party verification for ad placement, fraud detection, brand safety, and competitive separation can improve an RMN’s credibility and transparency. By disclosing the third-party providers used and the types of verification offered, RMNs build trust with advertisers and give them the confidence they need to invest.
Additionally, RMNs should disclose their staffing, processes, technology, inventory management, targeting, creative management, and self-service offerings. Transparency in these areas helps advertisers make informed decisions, optimize ad buys, and increase efficiency. Using existing IAB verification and capability disclosure guidelines ensures reliability and a more trustworthy, efficient advertising environment.
Future retail media standardization trends
The future of retail media is poised for significant growth, especially as standardization guidelines are widely adopted and implemented. Here are some trends we expect to see as retail media ad spending grows.
Widespread RMN adoption and spending
Standardization could spur greater RMN spending and drive broad adoption by advertisers who hesitated before due to concerns about metrics and performance comparability.
New partnerships and collaborations
Standardization may lead to new partnerships that weren’t possible before:
- Brands and retailers might team up to blend advertising and sales data for better-targeted campaigns.
- AdTech companies could also partner with multiple retailers to offer unified advertising solutions.
- Retail media networks and analytics firms could collaborate to provide deep insights into consumer behavior and campaign performance.
- Partnerships among retailers, including smaller ones seeking retail media measurement uniformity, may drive further standardization and create new advertising opportunities across product categories with audience overlap.
Ad format innovation
Agreeing on common standards simplifies how ads are measured and understood. Standardization may drive down costs and free up space for more imaginative, engaging ads in the future. For instance, the IAB/MRC’s common language is helping to promote consistency and clarity and fuel innovation across the board.
Incrementality focus
As standardization becomes more widespread, there may be a growing trend toward incrementality measurement, which measures the additional impact of advertising campaigns compared to what would have happened without them. Standardized metrics can help advertisers accurately gauge and optimize campaign effectiveness and maximize their marketing investments.
Growth of cross-platform ad targeting
Standardization may drive the growth of cross-platform ad targeting. With consistent metrics and measurement standards, advertisers will be able to track and compare their ad performance across platforms more accurately. This unified approach will improve ad targeting precision and ensure a consistent impact across RMNs.
Commerce media
Commerce media is changing retail advertising with its focus on verified data and real-time transaction insights, making campaigns more efficient. This shift could push for more uniform measurement standards across platforms and level the playing field. As commerce media gains traction, its emphasis on targeted advertising and ROI measurement might pave the way for universal metrics and clearer guidelines across retail networks.
Where does this leave modern advertisers?
Retail media is still at a crossroads. If standardization doesn’t occur soon, its growth may slow. For now, advertisers are resorting to custom strategies or relying on whichever network they feel is most effective for their products. They are likely to continue investing significantly in retail media, maintaining or increasing spending in the next year.
Although RMNs continue to be challenging without formally recognized standardization guidelines, the proposed IAB/MRC guidelines provide an effective starting point.

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. This approach connects recognition with understanding, making every campaign more effective and more human. What is the context gap in AI-driven marketing? 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. What does responsible intelligence look like in practice? At Experian, every contextual model we deploy adheres to our standards for transparent and responsible innovation.

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.

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. What’s the difference between first-party and third-party data onboarding? 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. When does first-party onboarding become third-party onboarding? 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. Why do marketers need both first- and 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. Latest posts

If you buy media today, you’re already feeling the shift: the best results don’t always come from broad, open auctions or static “safe site” lists; they’re coming from deals that combine the right data with the right inventory and let algorithms optimize in real time. That’s curation. And when it’s done right, it reduces data and media waste for buyers and raises eCPMs (effective cost per thousand impressions) and win rates for publishers. As part of our Cannes Content Studio series, leaders from Butler/Till, Index Exchange, OpenX, PubMatic, and Yieldmo discuss how curation cuts waste and lifts results. What is real curation? Real curation isn’t “packaging inventory.” It’s a strategic framework built on three pillars: 1. Unique data Privacy-compliant and accurate. 2. Strong supply connections Access to quality inventory from publishers at scale. 3. Optimization tools To measure, refine, and improve performance throughout the campaign lifecycle. Why it matters: Manual approaches hit a ceiling. They can’t react quickly to shifting content, identity signals, or auction dynamics. That’s where technology partners come in, keeping the optimization loop running continuously. Intelligence at every touchpoint Curation isn’t about shifting control between platforms. It’s about better brand decisions, connecting opportunity-rich supply to the brand’s preferred buying platform and enriching each buy with audience data. In practice, supply-side platforms (SSPs) are ingesting richer signals to route inventory more effectively and support frequency caps and deal prioritization, in collaboration with demand-side platforms (DSPs). "I think we’re seeing a shift toward bringing more DSP capabilities into the SSP, like supply-side targeting and data driven curation. Advancements in areas like CTV are enabling targeting based on content signals, and SSPs are pulling in more data to inform which supply is sent to the DSP, helping with things like frequency caps."Matt Sattel Why page-level targeting beats static lists Static domain lists were a useful first step for quality control. The intent was sound, but the approach was too cumbersome for today’s signal-rich buying. Today, AI and contextual engines read the page, not just the site, and adapt in real time. Page-level logic delivers three key benefits: Accuracy by targeting high-intent, page-level content. Relevance by matching the creative to both the content and the audience context. Speed by enabling campaigns to move away from underperforming pages in real time, without waiting for a manual trafficking change. "AI-driven contextual engines evaluate the page, not just the domain, to curate inventory in real time. That moves curation from static allowlists to adaptive logic for greater accuracy, relevance, and speed."Sophia Su Partnerships broaden who influences the buy Curation works when publishers, agencies, data partners, and platforms share signals and KPIs. Horizontal curation (across multiple SSPs) assembles broader, higher-quality reach and resilience, ideal for scale and diversity of supply. Vertical curation (an SSP’s in-house product) provides deep controls within a single exchange, useful for specific inventory strategies. Creative and data now shape supply and demand: better creative decisioning, tested against richer signals, improves outcomes. DSPs remain central for activation and pacing. But the sell-side’s growing intelligence means more accurate inventory routing and signal application before a bid ever fires. "Curation will continue to evolve through deeper data partnerships and expanded use across publishers and agencies, with more sophisticated types of optimization. DSPs will remain critical to activation, even as sell-side decisioning plays a larger role in identifying and shaping the supply to select."Mike McNeeley Curation delivers access and measurable performance Here’s what curated deals are delivering.

That’s why curated private marketplaces (PMPs) have grown at ~19% compound annual growth rate (CAGR) since 2019. "Publishers using supply-side curation see ~15% more diverse buyers and 20–25% better performance than buy-side-only targeting. Smarter packaging and signal application tighten auctions and strengthen outcomes."Howard Luks Holistic curation streamlines planning and outcomes Curation adds the data layer earlier in the buying process, starting at the supply-side. This creates more opportunities to reach the right audience and improves scale and performance. By replacing multiple line items with a single curated deal, campaign setup becomes faster and less error-prone. Curated deals also simplify measurement by including the necessary context for accurate attribution, while dynamic adjustments ensure campaigns remain optimized without requiring manual updates. "Publishers using supply-side curation see ~15% more diverse buyers and 20–25% better performance than buy-side-only targeting. Smarter packaging and signal application tighten auctions and strengthen outcomes."Gina Whelehan It’s much more streamlined, bringing more pieces together so we’re thoughtful and holistic. Adding the audience and data element creates more scale and strategy in how we curate supply and data, and ultimately better results for clients. The bottom line Curation has matured from buzzword to performance system. DSPs still anchor activation and pacing, but better sell-side pipes now pre-route inventory and apply signals before any bid starts, making the whole system faster and more accurate. When you combine unique signals, tight supply connections, and always-on optimization, you gain addressability, reduce waste, and achieve better business outcomes for both buyers and sellers.
