As the days get longer and the weather warms up, spring’s revitalizing energy naturally leads to realignment. For marketers, it’s the perfect moment to reevaluate strategy, especially as consumer behavior changes ahead of summer and brings a renewed interest in travel, outdoor activities, and social events. Making seasonal adjustments to your marketing strategy helps you adapt to these shifting behaviors, capitalize on 2025 marketing trends, and keep your brand relevant year-round.
When it comes to your marketing strategy, spring cleaning means clearing out outdated tactics, optimizing what works, and making room for smarter, more connected solutions. Take the time to ask yourself questions like:
- Are our audiences still relevant?
- Are we activating our data across the right channels?
- Are we collaborating with the right partners and using the right data clean room providers?
If there’s room for improvement, now is the best time to audit, refine, and refresh your marketing strategy before the high-stakes summer and winter seasons. With identity resolution, data enrichment, data clean room collaboration, and omnichannel activation through Experian, you can clean up what’s outdated and prep your strategy for summer success!
Rethink your data and identity resolution strategy
Your data is foundational to your strategy and is a great place to start your marketing strategy spring cleanup. If your customer information is outdated, incomplete, or fragmented across systems, every campaign built on top of it risks underperforming. Before jumping into segmentation, activation, or partnerships, assess the health of your data and identity infrastructure. This is your deep clean and an essential first step in ensuring everything else works better.
With signals disappearing, buying channels proliferating, and customer journeys getting more complex, the key to maintaining addressability is investing in persistent identity, complete consumer data, and collaborative measurement strategies that can weather these changes.
Here are some ways to rethink your marketing data management and identity strategies for the current environment.
Set the data foundation
A solid identity resolution strategy starts with high-quality, unified data. Consider a comprehensive refresh of your customer records by auditing and enhancing what you have for accuracy and depth.
As you’re thinking through spring marketing ideas, it’s an ideal time to enrich your first-party data by appending missing details, removing outdated records, and ensuring you enter summer with reliable, up-to-date profiles.
Data enrichment
Customer data naturally degrades, and eventually, you’ll need to dust it off by supplementing consumer records with current, high-quality insights and attributes. Experian data enrichment can help you seamlessly refresh records with updated demographic and behavioral data, giving detailed insights for precise targeting and relevant campaigns.
With over 5,000 attributes available, covering everything from age and income to shopping habits and media preferences, you can maintain the deepest, most up-to-date view of your consumers through every season.
Offline identity resolution and append
Offline identifiers — like names, physical addresses, and phone numbers — are the most persistent identity markers as they rarely change compared to digital cookies and device IDs. They’re essential for a stable identity foundation, and you can use them to develop a consistent, unified view of each household and individual.
Use this season to audit and tidy up your offline records. Are key identifiers missing? Are you relying on outdated addresses or duplicate names? Experian’s Offline Graph serves as the foundation to help unify those fragmented pieces, resolving identities across households and individuals to create a clean, consistent view of every customer. Think of this step as scrubbing baseboards or cleaning behind the fridge. It’s often overlooked but a prerequisite to a thorough spring refresh.
You can also use Offline Identity Append to append missing identifiers to improve match rates, boost data accuracy, and ensure addressability so that when summer campaigns launch, you’re ready to confidently meet your audience where they are.
Digital resolution via Digital Graph
This next step is like replacing your air filter each spring. You won’t see it, but you’ll definitely feel the difference in performance. Digital resolution ensures persistent, accurate targeting across devices and channels in a fragmented omnichannel environment.
Experian’s Digital Graph facilitates easy consumer identification and connection across the digital ecosystem. Our graph links digital identifiers like mobile ad IDs (MAIDs), connected TV IDs, and hashed emails to consumer profiles. So, when a customer interacts on a smartphone, a smart TV, and a laptop browser, those actions can all be tied back to the same individual or household in your database.
Collaborate securely in data clean rooms to close gaps
Matching partner data within your own secure space, a trusted third-party clean room, or Experian’s privacy-safe environment is an essential next step in your marketing spring cleaning strategy. But what is a data clean room?
A data clean room is a privacy-first way to enhance marketing data in a secure environment that allows brands and partners to match and analyze data without exposing personally identifiable information. It’s almost like organizing a shared closet. You both bring what you have, sort it safely, and leave with something more valuable without mixing up or exposing what’s personal. Secure collaboration enriches your understanding of consumers, boosts match rates, and ensures the highest data security standards.
Here are key data challenges you can tackle through data collaboration—whether in a clean room or across your broader data strategy.
Lack of insights or usable data
Without third-party cookies, marketers run the risk of losing valuable consumer insights. Collaborating with key partners lets brands enrich their first-party data and obtain a more comprehensive view of customer behaviors for informed decision-making.
Let’s say, for example, that an advertiser with sales data but no exposure data struggles to attribute sales to specific campaigns. By collaborating securely with a measurement partner who provides exposure data, the advertiser can confidently link sales to ad exposure and optimize future campaigns with an understanding of who saw their ad and made a purchase.
We anticipate that data collaboration will be a key marketing trend in 2025 alongside signal loss.
Low or no match rates
When businesses handle matching internally, discrepancies like name variations (e.g., John Doe vs. Jonathan Doe) or mismatched identifiers (hashed emails vs. MAIDs) often result in poor match rates. Experian’s identity resolution capabilities, meticulous hygiene processes, resolution logic, and comprehensive identity graphs significantly enhance these match rates.
For example, if a data provider had physical addresses and a demand-side platform (DSP) had email addresses, they couldn’t collaborate with different identifiers. Using Experian Collaboration, however, their data could be resolved with offline identity data from our graph, enabling them to share their collaboration data and improve their marketing efforts.
Data security
When it comes to data collaboration, protecting your proprietary and customer information is non-negotiable. That’s why Experian operates with some of the industry’s strictest data security, privacy, and compliance protocols.
We support identity resolution and data collaboration within the most secure environments available — data clean rooms built to prevent sensitive customer data from ever being exposed. Instead of moving or sharing your raw data, we ensure all records are anonymized before any analysis occurs.
Additionally, Experian’s clean room integrations with trusted partners give clients flexibility without compromising compliance. All solutions are designed to meet GDPR, CCPA, and industry-specific data governance standards, with full audit trails and customizable access controls.
Connect and activate
Once your data is clean, enriched, and resolved, the next step is to activate it efficiently across the channels where your audiences spend time. This step is like putting everything back in place after a deep clean so everything is functional, easy to access, and ready to deliver results.
As you get ready to put your spring marketing ideas into motion, it’s time to streamline your activation approach and make sure your customer data is working hard for you.
First-Party Onboarding
With Experian First-Party Onboarding, you can ship data where needed using flexible data solutions for your activation strategy. This step is like labeling and organizing your freshly cleaned marketing closet, so each audience segment is ready to deploy wherever you need it.
We make it easy to:
- Understand your customers on a deeper level
- Seamlessly onboard your customer data for use across programmatic, social, and advanced TV platforms
- Combine your first-party data with Experian syndicated audiences for enriched targeting
- Deliver those audiences to any destination that accepts Experian Audiences — whether a DSP, social platform, or publisher
- Increase match rates, extend reach, and lower activation costs
Transact in the ecosystem with the Experian ID
To aid in the activation process, Experian ID is a unified identifier that acts as a privacy-safe bridge between fragmented emails, device IDs, and addresses, helping you activate audiences across all media channels.
Experian ID keeps your data protected and connected whether you send it to DSPs, social platforms, or data clean rooms. This allows for secure activation and performance tracking across the ecosystem without exposing personally identifiable information (PII).
Like sealing and storing your seasonal belongings in airtight containers, Experian ID keeps your data clean, safe, and always ready for use.
Use fresh audience insights to inform segmentation
After deep-cleaning your data, enriching profiles, and resolving identities, you’ll want to ensure your segmentation reflects that renewed foundation. Just like clearing expired ingredients from your pantry, spring is an ideal time to toss outdated audience definitions and replace them with insights that are fresh, relevant, and ready to perform.
With Experian’s modern audience tools, you can create smarter segments, power omnichannel strategies, and continue reaching high-value consumers even in cookieless environments.
Our marketing data management tools make it easy to:
- Build detailed, personalized profiles using over 5,000+ behavioral and lifestyle marketing attributes that go far beyond basic demographics.
- Choose from 2,400+ pre-built syndicated segments or collaborate with Experian to create custom audiences tailored to your KPIs and campaign goals.
- Append fresh attributes to your CRM to keep profiles accurate, performance-ready, and reflective of current consumer behaviors and life stages.
Together, these tools help sharpen your segmentation strategy and ensure up-to-date audience insights power every campaign. Let’s break down how smart combinations and contextual precision can further elevate your segmentation.
Combine our identity graphs and Marketing Attributes for sharper targeting
Combining Experian’s identity graphs with Marketing Attributes gives you both the who and the why behind your audience and helps you act on that insight with precision. It’s like giving your closet a total spring refresh — not just purging what doesn’t fit but also organizing what’s left into ready-to-wear outfits.
- Digital Graph + Marketing Attributes: Link real-time digital behavior (like CTV, mobile, or web activity) with rich consumer insights to create segments that perform across channels, from mobile to CTV to social.
- Offline Graph + Marketing Attributes: Tie persistent offline identifiers like name and address to behavioral and lifestyle data, making it easier to plan full-funnel strategies from direct mail to digital display.
This approach gives you the clarity and flexibility to build richer personas, reach more qualified audiences, and target with confidence across any environment.
Activate smarter with Contextually-Indexed Audiences
Spring cleaning your strategy also means letting go of legacy tools, especially those relying on cookies or outdated tracking methods.
With Experian’s Contextually-Indexed Audiences, you can reach consumers based on the content they’re engaging with, not their identifiers. We map millions of websites to real audience segments so you can target high-intent consumers in a privacy-safe, way.
For example, an automotive brand looking to reach high-intent luxury EV shoppers can activate Experian’s “in-market for a luxury electric car” segment. With contextually-indexed targeting, that brand’s ads will appear on websites that over-index for visitors in that audience — such as premium car review sites or sustainability-focused blogs — without relying on user identifiers.
This allows the brand to scale performance safely and efficiently in cookieless environments while achieving strong engagement metrics.
Activate across channels with confidence
After refreshing your data, segmentation, and partner strategies, the final step in your spring cleaning is putting all that prep work into action — efficiently and at scale. Think of this as your final sweep: optimizing where and how you activate your audience to ensure every touchpoint is aligned, accurate, and impactful.
With your updated segments and sharpened identity framework in place, you can reach consumers across display, mobile, connected TV (CTV), and emerging digital channels. Experian provides the tools to activate seamlessly — backed by privacy-safe, high-quality data and flexible integration options.
Third-Party Onboarding: Expand reach with external data sets
Experian’s Third-Party Onboarding capabilities make it easy for brands to augment their first-party data strategies on their preferred activation platforms with easy access to high-quality, activation-ready third-party audiences.
For you, this means you no longer have to manage the onboarding process yourself or worry about compatibility. Instead, you can:
- Enhance your first-party targeting with third-party data that’s already privacy-safe and activation-ready.
- Reach more qualified consumers by layering in external behavioral, lifestyle, or intent signals.
- Maximize scale across your preferred platforms using Experian’s established integrations and ecosystem support.
With Experian as your trusted partner, your audience strategy becomes more flexible, more scalable, and more effective, giving you the power to engage the right consumers beyond your own CRM.

2024 marked a significant year. AI became integral to our workflows, commerce and retail media networks soared, and Google did not deprecate cookies. Amidst these changes, ID bridging emerged as a hot topic, raising questions around identity reliability and transparency, which necessitated industry-wide standards. We believe the latest IAB OpenRTB specifications, produced in conjunction with supply and demand-side partners, set up the advertising industry for more transparent and effective practices. So, what exactly is ID bridging? As signals, like third-party cookies, fade, ID bridging emerged as a way for the supply-side to offer addressability to the demand-side. ID bridging is the supply-side practice of connecting the dots between available signals, that were generated in a way that is not the expected default behavior, to understand a user’s identity and communicate it to prospective buyers. It enables the supply-side to extend user identification beyond the scope of one browser or device. Imagine you visit a popular sports website on your laptop using Chrome. Later, you use the same device to visit the same sports website, but this time, on Safari. By using identity resolution tools, a supply-side partner can infer that both visits are likely from the same user and communicate with them as such. ID bridging is not inherently a bad thing. However, the practice has sparked debate, as buyers want full transparency into the use of a deterministic identifier versus an inferred one. This complicates measurement and frequency capping for the demand-side. Before OpenRTB 2.6, ID bridging led to misattribution as the demand-side could not attribute ad exposures, which had been served to a bridged ID, to a conversion, which had an ID different from the ad exposure. OpenRTB 2.6 sets us up for a more transparent future In 2010, the IAB, along with supply and demand-side partners, formed a consortium known as the Real-Time Bidding Project for companies interested in an open protocol for the automated trading of digital media. The OpenRTB specifications they produced became that protocol, adapting with the evolution of the industry. The latest evolution, OpenRTB 2.6, sets out standards that strive to ensure transparency in real-time bidding, mandating how the supply-side should use certain fields to more transparently provide data when inferring users’ identities. What's new in OpenRTB 2.6? Here are the technical specifications for the industry to be more transparent when inferring users’ identities: Primary ID field: This existing field now can only contain the “buyeruid,” an identifier mutually recognized and agreed upon by both buyer and seller for a given environment. For web environments, the default is a cookie ID, while for app activity, it is a mobile advertising ID (MAID), passed directly from an application downloaded on a device. This approach ensures demand-side partners understand the ID’s source. Enhanced identifier (EID) field: The EID field, designated for alternative IDs, now accommodates all other IDs. The EID field now has additional parameters that provide buyers transparency into how the ID was created and sourced, which you can see in the visual below: Using the above framework, a publisher who wants to send a cross-environment identifier that likely belongs to the same user would declare the ID as “mm=5,” while listing the potential third-party identity resolution partner under the “matcher” field, which the visual below depicts. This additional metadata gives the demand-side the insights they need to evaluate the reliability of each ID. "These updates to OpenRTB add essential clarity about where user and device IDs come from, helping buyers see exactly how an ID was created and who put it into the bidstream. It’s a big step toward greater transparency and trust in the ecosystem. We’re excited to see companies already adopting these updates and can’t wait to see the industry fully embrace them by 2025."Hillary Slattery, Sr. Director, Programmatic, Product Management, IAB Tech Lab Experian will continue supporting transparency As authenticated signals decrease due to cookie deprecation and other consumer privacy measures, we will continue to see a rise in inferred identifiers. Experian’s industry-leading Digital Graph has long supported both authenticated and inferred identifiers, providing the ecosystem with connections that are accurate, scalable, and addressable. Experian will continue to support the industry with its identity resolution products and is supportive of the IAB’s efforts to bring transparency to the industry around the usage of identity signals. Supply and demand-side benefits of adopting the new parameters in OpenRTB 2.6 Partner collaboration: Clarity between what can be in the Primary ID field versus the EID field provides clear standards and transparency between buyers and sellers. Identity resolution: The supply side has an industry-approved way to bring in inferred IDs while the demand side can evaluate these IDs, expanding addressability. Reducing risk: With accurate metadata available in the EID field, demand-side partners can evaluate who is doing the match and make informed decisions on whether they want to act on that ID. Next steps for the supply and demand-sides to consider For supply-side and demand-side partners looking to utilize OpenRTB 2.6 to its full potential, here are some recommended steps: For the supply-side: Follow IAB Specs and provide feedback: Ensure you understand and are following transparent practices. Ask questions on how to correctly implement the specifications. Vet identity partners: Choose partners who deliver the most trusted and accurate identifiers in the market. Be proactive: Have conversations with your partners to discuss how you plan to follow the latest specs, which identity partners you work with, and explain how you plan to provide additional signals to help buyers make better decisions. We are beginning to see SSPs adopt this new protocol, including Sonobi and Yieldmo. “The OpenRTB 2.6 specifications are a critical step forward in ensuring transparency and trust in programmatic advertising. By aligning with these standards, we empower our partners with the tools needed to navigate a cookieless future and drive measurable results.” Michael Connolly, CEO, Sonobi These additions to the OpenRTB protocol further imbue bidding transactions with transparency which will foster greater trust between partners. Moreover, the data now available is not only actionable, but auditable should a problem arise. Buyers can choose, or not, to trust an identifier based on the inserter, the provider and the method used to derive the ID. While debates within the IAB Tech Lab were spirited at times, they ultimately drove a collaborative process that shaped a solution designed to work effectively across the ecosystem.”Mark McEachran, SVP of Product Management, Yieldmo For the demand side: Evaluation: Use the EID metadata to assess all the IDs in the EID field, looking closely at the identity vendors’ reliability. Select partners who meet high standards of data clarity and accuracy. Collaboration: Establish open communication with supply-side partners and tech partners to ensure they follow the best practices in line with OpenRTB 2.6 guidelines and that there’s a shared understanding of the mutually agreed upon identifiers. Provide feedback: As OpenRTB 2.6 adoption grows, consistent feedback from demand-side partners will help the IAB refine these standards. Moving forward with reliable data and data transparency As the AdTech industry moves toward a cookieless reality, OpenRTB 2.6 signifies a substantial step toward a sustainable, transparent programmatic ecosystem. With proactive adoption by supply- and demand-side partners, the future of programmatic advertising will be driven by trust and transparency. Experian, our partners, and our clients know the benefits of our Digital Graph and its support of both authenticated and inferred signals. We believe that if the supply-side abides by the OpenRTB 2.6 specifications and the demand-side uses and analyzes this data, the programmatic exchange will operate more fairly and deliver more reach.

Note: This Ask the Expert was recorded prior to Experian’s acquisition of Audigent and discusses industry trends and how we’ve worked together in the past. Adopting new strategies based on trust due to evolving privacy regulations and the gradual loss of traditional signals, like third-party cookies, is essential to successfully navigating the future of digital advertising. Advertisers and marketers are at a crossroads, facing the challenge of maintaining personalization and precision while respecting consumer expectations around privacy. To stay competitive, brands must adopt future-ready strategies that focus on trust, privacy-forward technologies, and scalable solutions. In our latest Ask the Expert segment, recorded before Experian acquired Audigent, we explore how first-party data and advanced contextual audience targeting are two critical approaches for successfully navigating these changes. With insights from Greg Williams, President of Audigent, now part of Experian, and Crystal Jacques, VP of Sales at Experian, we discuss how these tools can empower your brand for long-term success. First-party data as a cornerstone strategy First-party data, a powerful tool for building meaningful connections with your audience, has emerged as a fundamental pillar of future-ready strategies. When collected and used effectively, it provides brands with a detailed understanding of consumer preferences and behaviors, enabling real-time campaign adjustments for maximum impact. “Data has become part of every step of the digital advertising supply chain, and should be part of everybody’s buys… the more you can include data in your digital marketing, the better off and the more power you have."Greg Williams, President, Audigent With the continual loss of signal, including third-party cookies, first-party data has proven to be key for brands to stay both competitive and privacy-compliant. Brands using first-party data are better positioned to overcome the challenges of signal loss. This data facilitates improved media targeting and personalized messaging, driving greater engagement and return on investment. Contextually-Indexed Audiences build relevance Experian’s Contextually-Indexed Audiences enable advertisers to target users based on their interests in real-time, without relying on cookies or mobile ad IDs. Machine learning analyzes and maps traffic from over two million websites, linking to Experian’s 2,400 audience segments. With added benefits like audience customization and flexible activation through Audigent’s private marketplaces (PMPs) or demand-side platforms, Experian is setting a new standard for scalable audience targeting. For automotive advertisers, this could mean reaching consumers actively researching luxury electric vehicles on relevant sites. Unlike outdated methods, contextual targeting aligns the message with consumer intent, balancing high precision with consumer privacy. Automotive success story Audigent’s innovative solutions have delivered tangible results. Williams mentions how they helped an automotive brand achieve double the scale and triple their goal of driving test drives. This stands as a testament to the real-world effectiveness of contextual audience strategies and Experian's role in executing them. How to stay ahead of change Here are five strategies to help your brand remain future-ready amid privacy challenges and signal loss: Prioritize first-party data: Build trust and improve targeting accuracy by relying on data that you own directly from your consumers. Test privacy-forward tools: Experiment with solutions like contextual targeting and Google’s Privacy Sandbox to future-proof your advertising.

CES 2025 will be an exciting opportunity to explore how we can work together to shape the year ahead. Here are four themes we expect to take center stage at the event. “There is no better way to kick off the calendar year than with clients and industry peers that are excited to collaborate on new business opportunities. People come straight off the holidays energized by CES and with a pipeline of deals to work on for the coming month. In-person meetings always trump virtual calls and everyone in the industry comes together to make it a fruitful week.”Crystal Jacques, Head of Enterprise Partnerships 1. Addressability in a signal-loss world Addressability has become a cornerstone in AdTech as brands aim to deliver personalized experiences while navigating evolving privacy regulations and signal loss. This shift has prompted advertisers to rethink how they reach and engage audiences. In this environment, alternative identifiers such as UID2 and ID5 have gained traction, offering brands new avenues to target consumers across platforms while respecting privacy. Addressability has shifted from a straightforward tracking mechanism to a multifaceted strategy that combines identity solutions, contextual insights, and collaboration across the ecosystem. ID Bridging and the new OpenRTB 2.6 specs As the industry loses identity signals, it becomes increasingly difficult to identify audiences on the supply-side and make them reachable for the demand-side. The supply-side has used the practice of ID bridging to do just that. ID bridging is the supply-side practice of connecting the dots between available signals to infer a user’s identity and communicate it to prospective buyers. This practice sparked debate, as buyers want full transparency into the use of a deterministic identifier versus an inferred one. "The OpenRTB 2.6 specifications are a critical step forward in ensuring transparency and trust in programmatic advertising. By aligning with these standards, we empower our partners with the tools needed to navigate a cookieless future and drive measurable results.”Michael Connolly, CEO, Sonobi The industry needs widely accepted standards, and that's what we believe the industry has with the IAB Tech Lab's OpenRTB 2.6. The specifications dictate the data the supply-side needs to include in the Primary ID and Enhanced Identifier (EID) fields. In doing so, the demand-side receives more transparent information on when bids have inferred IDs and where they came from. As authenticated signals decrease due to cookie deprecation and other consumer privacy measures, we will continue to see a rise in inferred identifiers. Experian’s industry-leading Digital Graph has long supported both authenticated and inferred identifiers, providing the ecosystem with connections that are accurate, scalable, and addressable. Experian will continue to support the industry with its identity resolution products and is very supportive of IAB’s efforts to bring transparency to the industry around the usage of identity signals. 2. Commerce media consolidation As the world of commerce media expands beyond traditional retail media, we’re seeing a surge of networks across various verticals—financial, travel, and beyond—all competing to capture shoppers’ attention. With each company independently building its own media network, the need for strategic partnerships has never been more evident. Key players face challenges in scaling these networks and meeting growth targets due to infrastructure and funding limitations. In response, the industry is shifting toward partnerships – and potentially consolidation – to create networks that allow advertisers to reach customers across the entire shopping journey – from digital to in-store. To succeed, commerce media networks must form strategic partnerships to enhance their data and identity capabilities and provide advertisers with a complete view of their customer. “With annual growth in billions of dollars, the revenue potential for RMNs is massive. Organizing customer data, segmenting customers, generating insights, creating addressable audiences, and activating campaigns are all critical steps for a RMN to realize that revenue potential. RMNs should select a partner that provides the data, identity and analytical resources to create the winning formula for marketers, customers and retailers.”Steve Zimmerman, Director of Analytics With Experian’s expertise in data and identity solutions, commerce media networks can overcome data fragmentation, create high-quality audiences, and maximize addressability across their entire customer base. This collaborative, partner-led approach empowers retailers to utilize their first-party customer data but not be limited by in-house resources. As the commerce media space matures, those who embrace these partnerships and data-driven solutions will be well-positioned to capture the full potential of this expanding market. 3. Navigating complex privacy regulations With privacy concerns intensifying, consumers are more conscious about data usage, and a series of state-level privacy laws are poised to take effect across the U.S. Multiple state-level laws makes compliance more challenging for marketers since no two laws are the same. While a federal privacy law remains unlikely for 2025, discussions around data ethics, compliance, and transparency will be prominent at CES, especially as a new administration assumes office. Our privacy-forward audience solutions Our Geo-Indexed and Contextually-Indexed Audiences help marketers reach the right consumers while prioritizing data privacy. Created without sensitive personal information, these audiences utilize geographic and contextual signals – not personal identifiers — to offer relevant targeting. These new tools provide both privacy and accuracy, giving advertisers and publishers a competitive edge. “By embracing innovations in geo-based targeting and adhering to responsible data strategies, you can not only comply with these laws but continue to reach your intended audiences effectively.”Jeremy Meade, VP, Marketing Data & Operations As privacy regulations evolve, marketers need trusted allies who can provide transparent, compliant solutions. With deep roots in data protection and security, you can confidently partner with Experian as we proactively stay ahead of regulations and strictly follow all consumer privacy laws. 4. Rise of curation As privacy regulations and signal loss reshape the AdTech ecosystem, curation can optimize programmatic campaigns by connecting advertisers with valuable audiences. This emerging trend utilizes audience, contextual, and supply chain signals to curate high-quality inventory packages for advertisers. By blending insights with inventory, curation ensures greater addressability, efficiency, and performance for both advertisers and publishers. Supply-side platforms (SSPs) are taking a more active role in curating audiences and inventory. SSPs now collaborate with data providers to match buyer and publisher first-party data in real-time, creating curated private marketplaces (PMPs) that deliver transparency, efficiency, and improved match rates. SSPs can send deal IDs to multiple DSPs, which allows advertisers to deploy audience-based campaigns without restrictions on which DSPs or identifiers can be used. However, curation isn’t without challenges. It can add complexity, lead to redundant buys, and even reduce publisher control over inventory. Transparency, quality benchmarks, and strategic partnerships will be critical for maximizing the benefits of curation in 2025. Experian, in partnership with Audigent and others, is at the forefront of enabling privacy-forward curation strategies. Experian and Audigent’s combined capabilities bring together first-party publisher data, contextual signals, and advanced identity resolution to create curated PMPs that empower marketers to deliver precise, impactful campaigns.
