A few weeks ago, Experian and OpenX hosted a supply-side think tank at our New York City office. Over 70 industry leaders met to talk about targeting in a cookieless future and how we can reach consumers in intentional ways.
Publishers and supply-side partners shared what challenges they face, what solutions they’re considering, and what the future holds once the third-party cookie begins to deprecate in 2024. In this blog post, we’ll cover the top challenges, cookieless solutions, and actionable strategies we discussed at the event that can help publishers, their partners, and agencies make informed decisions about how to navigate tomorrow’s digital ecosystem.
Four main challenges
Four main challenges were discussed at the event:
First-party data monetization
Publishers possess a wealth of first-party data, but collecting and centralizing this information can be difficult for actionable insights. Streamlining data centralization and organizing first-party data is crucial for effective decision-making. Even with a wealth of first-party data, it’s important to be aware of any blind spots in your data and enrich those gaps with data partners rooted in offline connections.
“We appreciate the opportunity to participate in the supply-side think tank led by OpenX and Experian, two industry leaders in navigating a cookieless future. We’re excited to collaborate with them on testing privacy sandbox APIs, identity resolution products, and audience development tools to enhance creator monetization and support an open internet amidst rapid technological and regulatory shifts.”
Patrick McCann, SVP, Research, Raptive
Lack of authenticated data and persistent IDs
The deprecation of third-party cookies means there will be a shortage of authenticated user data and persistent identifiers. Without this information, targeting and personalization become more challenging. Participants discussed the need to find alternative ways to gather and use personal data responsibly. It’s time to start evaluating data partners who have accurate, multi-source compiled, privacy-compliant data with the dedication to reach and recency.
Fragmentation and scale with alternative IDs currently in the market
The multitude of alternative identifiers in the market poses a challenge for publishers. Each of these identifiers comes with its own set of rules and integration processes, leading to fragmentation and complexity. Publishers must find ways to navigate this landscape. Look to ID agnostic partners who provide a way to access multiple IDs at scale.
“The industry needs a more streamlined standard to integrate alternative IDs, given the ongoing challenges of third-party cookie deprecation, measurement, and clean rooms. This burden falls heavily on product and engineering teams, who must prioritize and address these issues one at a time.”
Ryan Boh, Head of Identity, Lockr
Time
Cookie deprecation is almost here. It is crucial to organize your legal, engineering, and product resources, and align internal go-to-market strategies. Establish partnerships that work with your team to follow these timelines and help build phased or cohesive strategies to prepare for a path to monetization. It is imperative to establish a sense of urgency and not wait for others to take the lead. Start testing now to determine if your infrastructure is ready and capable. Many partners who attended the think tank offered insights on how they’ve been tackling challenges to help their industry peers.
Solutions and action plans for a cookieless future
Participants discussed ways they are starting to prepare for a cookieless future and other approaches on their roadmaps:
Work with data partners heavily rooted in offline data across the ecosystem
Enriching your first-party data with partners who rely on offline IDs can help bridge gaps in your audience knowledge. This approach allows you to build a more complete audience profile while third-party cookies are still operational.
Experian is rooted in deterministic offline data and has decades of experience managing it safely. We have insights on over 250 million U.S. consumers and 126 million U.S. households. With our digital technology assets, we bring in 4 billion devices and 1 trillion device signals to definitively connect offline records to online identifiers. With Experian identity widespread adoption throughout the industry, we’re able to provide a common language for us all to collaborate. Experian identity organizes people into households, links their digital devices and IDs to them, enriches their identity with behavioral attributes, and then makes this data actionable in any environment, all while maintaining consumer privacy and data regulations.
“Experian’s supply-side think tank provided a platform for publishers and AdTech companies to discuss the challenges posed by cookie deprecation, privacy regulation updates, and identity restrictions. It highlighted the need for AdTech companies to assist publishers in addressing anonymous users without requiring a value exchange — fostering a mutually beneficial and privacy-compliant open web solution.”
Anthony Caccioppoli, Head of AdTech & Solutions, Insider
Develop your own persistent ID
Creating and maintaining a proprietary persistent ID can be a valuable cookieless solution. It provides control and independence in the new environment post cookie, giving publishers the ability to maintain a consistent user profile.
Use your data to expand contextual targeting opportunities
Contextual targeting involves placing ads based on the content of the web page rather than user data. In the absence of cookies, this strategy can prove effective in reaching relevant audiences.
“The masking or deprecation of IP addresses will eventually impact the availability of addressable IDs in non-authenticated web environments. In addition to ensuring maximum resiliency of our Graph and increasing support for authentication-based IDs, we are also investing in research and development around the use of other signals, such as contextual data, to maintain behavioral targeting inside non-authenticated environments. We will be sharing our findings and future plans in this space in the coming months.”
Budi Tanzi, VP, Product, Experian
Facilitate a knowledge exchange
Reach out to your network to find out what others are testing and what’s working. Start collaborating with agencies and brands across the buy-side to meet their needs.
“The collaborative spirit displayed by our partners constantly inspires me. Listening to the obstacles our industry faces allows this community to build strong relationships, create action plans, and deliver true value.”
Carly Allcorn, Account Executive, Publisher & Supply-Side Partnerships, Experian
Invest in an identity graph
Invest in an identity graph provider to sync first-party cookies and addressable IDs. This ensures that your data remains accessible and actionable in a cookieless world.
“Many participants at our think tank with Experian expressed the need to find an identity solution while also exploring other ways they can start to address cookie deprecation while maintaining business as usual.”
Callie Askenas, Director of Publisher Development, OpenX
How Experian and OpenX can help
Graph from Experian captures all available digital identifiers in real-time and resolves them back to individuals and households. We’re signal agnostic, continuously expand the IDs we support, and futureproof identity resolution through a combination of deterministic, probabilistic, and cookieless identifiers.
Experian is a key player in OpenX’s OpenAudience solution and helps to power many of their data segments as well as their identity graph. While OpenX collaborates with a variety of providers and operates a fully interoperable platform, Experian remains valuable to the core technology within OpenX’s supply-side platform (SSP).
Experian can help you prepare for the cookieless future
It’s clear that the cookieless future poses some unique challenges for publishers, but there are solutions. Publishers and their supply-side partners can come up with strategies to target consumers in intentional ways by continually testing multiple identifiers and cookieless solutions, developing their own persistent ID, creating velvet rope content, and returning to contextual targeting. Collectively, these actionable strategies can help ensure that publishers have a more successful transition into a cookieless future.
Experian has been preparing for signal loss for quite some time and we continue to make substantial investments to ensure our resiliency and the resiliency of our customers. We continue to diversify our signal creating profiles with more persistent identifiers which allows us to pair authentication-based universal identifiers such as UID2 into our Graph seamlessly.
Experian is ready and we are here to navigate the future of privacy together.

Gaming companies sit at a unique crossroads: they’re part entertainment powerhouse, part tech platform, part media company. Whether you’re publishing blockbuster titles, running a mobile game network, or building immersive in-game ad experiences, you have access to vast amounts of player data—and massive potential for growth. What's standing in the way of growth and loyalty Video game publishers and platforms are increasingly turning to data to understand, engage, and retain their players. But that’s easier said than done. Here are the top challenges they face: Data lives in silos. Gaming companies often collect data across multiple platforms—console, PC, mobile—but can’t stitch together a full view of the player across devices and titles. Identity is hard to resolve. Players interact across games, apps, websites, and platforms. It’s tough to connect all those signals and create a consistent, personalized experience. Privacy is non-negotiable. Regulations are tightening. Any solution must not only be powerful—it must be privacy-safe. Ad performance is difficult to measure. It’s often unclear which campaigns are driving engagement, conversions, or purchases—especially across fragmented digital touchpoints. How Experian can help you win with data and identity Experian helps gaming companies stop leaving value on the table. We turn scattered player data into a single, unified view—giving you the foundation to better understand and engage your players. Our approach: Organize, enrich, activate 1. We clean and unify your data We help you build a solid identity foundation by resolving messy, duplicate, or outdated records across systems. That means your player data from mobile, console, PC, and web all connects—giving you a clear view of how your users engage across games and platforms. 💡 How it’s working: A global interactive gaming company is partnering with Experian to unify and enrich player profiles across systems—boosting the performance of both player engagement campaigns and in-game monetization strategies. 2.

We enrich profiles and help you activate across channels We enhance your player records with hundreds of attributes—so you can create custom segments that work. Then, we help you activate those audiences in real-time across digital, social, and programmatic platforms. 💡 How it’s working: A global gaming publisher used Experian to build custom audiences and activate across programmatic channels, driving higher in-game engagement and ad ROI. Turning audiences into ad revenue In addition to improving their own player marketing, gaming companies are unlocking a second growth engine: ad revenue from non-endemic brands. Much like retail media networks, game publishers and platforms are realizing the value of their audience data. From airlines and automakers to QSR and CPG brands, advertisers are taking notice of the high-value, high-intent audiences inside game environments. But to attract that ad spend, publishers need to offer more than impressions—they need precise audience targeting, cross-device identity, and reliable measurement. How Experian helps drive better ad performance To appear authentically to a gamer, you need to know who they are and what they care about. Experian helps marketers understand a person’s behaviors and preferences to enable relevant, personalized advertising. And since nobody wants to see the same ad ten times during a session, we help manage ad frequency across devices and placements to protect the player experience. Our approach: Extend reach, measure results 1. We expand your digital reach Experian makes it easier to find and connect with your players wherever they are—across devices, platforms, and publishers. We help you build scalable audiences you can reach programmatically and with precision. 💡 How it’s working: Unity, a leading gaming platform, is redefining the way marketers reach their audiences across major and emerging channels. They’ve tapped into Experian’s syndicated audiences to gain player insights and help advertisers connect with gaming audiences across mobile, web, and connected TV (CTV) based on behaviors and preferences. 2. We help you measure what matters Whether your goal is app installs, in-game purchases, ad engagement, or player retention, we help connect the dots. You’ll know which campaigns are driving action—and where to double down. 💡 How it’s working: A leading global game publisher is working with Experian to enrich player profiles, build and activate audience segments, and measure how campaigns drive in-game engagement and purchases—giving them a clearer view of ROI across digital channels. Why choose Experian Whether you’re trying to build stronger player relationships or turn your audience into a high-performing advertising engine, Experian gives you the data and identity foundation to make it happen. We help you: Organize and clean your player data Resolve identities across digital touchpoints Enrich your data with deep, actionable insights Build and activate target audiences Measure impact across the player journey Let's power up together We’re already supporting leading brands across the gaming ecosystem—from global game publishers and mobile app developers to in-game ad networks and gaming platforms.

To meet this challenge, MiQ integrated Experian’s Digital Graph into their Identity Spine, creating a more comprehensive view of their clients’ target audiences and ensuring their data-driven solutions remain effective, regardless of the signal source or identifier in use. What is Experian's Digital Graph? Experian’s Digital Graph is like a puzzle, connecting billions of digital identifiers to create a complete view of consumers. As signal loss makes targeting harder, our Digital Graph helps marketers stay connected by linking cookies, mobile ad IDs (MAIDs), hashed emails (HEMs), IP addresses, connected TV (CTV) IDs, and universal IDs, like Unified ID 2.0 (UID2) and ID5. We put the pieces together, matching first-party data to a variety of digital IDs for better targeting, measurement, and cross-device insights—so you don’t have to. Challenge: Strengthen targeting capabilities amidst signal loss MiQ needed to stay agile in its strategy and partnerships to ensure digital connectivity amidst ongoing signal loss. To maintain campaign performance and scale, MiQ sought privacy-first partners they could integrate into their Identity Spine. MiQ’s primary objectives included: Strengthen audience targeting across all digital environments, with or without cookies. Reach target audiences in privacy-compliant ways. Maintain or increase the scale — even as reliance on cookie-based targeting declines. The solution: Integrating Experian's Digital Graph into MiQ's Identity Spine MiQ incorporated Experian’s Digital Graph, licensing HEMs, UID2s, and third-party partner cookies, into their proprietary Identity Spine. MiQ’s Identity Spine seamlessly connects over 60 cookieless data feeds and 25 ID solutions. “Experian’s Graph has bolstered our already comprehensive, multi-ID Identity Spine with incredible data on cross-device ownership and cross-channel behavior.”Georgiana Haig, Strategy and Partnerships Director, MiQ Results: MiQ expanded the reach and scale of their Identity Spine The integration of Experian’s Digital Graph with MIQ’s Identity Spine enabled marketers to find, grow, and measure customers across screens even as signal loss evolves and traditional identifiers fluctuate. The integration allowed MiQ to: Create a unified view: MiQ now has a unified view of its clients’ target audiences, enhancing their audience understanding with the addition of 6.5 devices to each matched IP address, enhancing scale and targeting capabilities.

Summer may be vacation season for consumers, but it's go time for marketers. Between holiday weekends, travel season, and changing shopping habits, the pressure is on to deliver campaigns that land and convert. If you're feeling behind, you're not alone. Many marketers face the same challenge every year: How do you actually use the customer data you have to fuel high-impact, seasonal marketing? And how do you ensure your brand shows up in front of the right people in the right place before the competition beats you to it? That’s where Experian comes in. With Experian’s advanced Audience solutions, you can get ahead of the trends, connect with vacation-ready shoppers, and optimize performance across digital, TV, and retail media using customer data for seasonal marketing. Capitalize on vacation excitement to drive sales and growth Summer travel often triggers a surge in pre-trip spending. Surveys show that 82% of consumers plan to travel this summer, and according to Fortune, today’s travelers spend thousands of dollars on things like luggage, apparel, and recreation gear before they even leave their homes! But while consumer demand is heating up, so are the challenges. Marketers are navigating a turbulent economic environment shaped by shifting demand curves, tighter budgets, the rising cost of goods, and supply chain disruptions caused by newly imposed tariffs. These pressures are forcing teams to rethink everything from product positioning to pricing strategies. In this climate, it’s more important than ever to maximize performance, reduce waste, and stay laser-focused on reaching high-intent audiences likely to convert. Using customer data for seasonal marketing helps brands predict and capture demand with precise, relevant targeting. Whether your customers are planning a trip to the beach or hiking the Rockies, timely messaging and audience alignment can drive engagement and conversion. Experian Audiences power effective audience strategies But even the most compelling campaigns can fall flat if you're working with incomplete data, outdated segments, or generic targeting. Consumer data providers like Experian can help you fix that. Our Audience solutions help you go beyond assumptions and truly understand who your shoppers are, what they’re planning, and how they behave, so you’re ready to get in front of their summer plans. Six steps to creating a successful seasonal marketing campaign When you’re ready to turn summer intent into strategy, Experian Audience solutions help you translate vacation-driven behaviors into high-performing campaigns. Each product in the Experian Audience suite supports a specific stage in seasonal marketing planning and execution. 1. Define your goals Before diving into channels and creatives, get clear on your customer database marketing goals. Are you trying to increase online purchases? Drive in-store traffic? Expand brand awareness? Use Syndicated Audiences to set fast, focused goals. If you’re short on time, Experian’s 2,400+ Syndicated Audiences give you a head start. These pre-built, behavior-based segments — from luxury travelers to seasonal sports enthusiasts — help you quickly identify who to target, where they spend time, and how to message to them. With segments ready to plug into 30+ activation platforms, you can ensure quick, confident activation. 2. Decide what data you need and which audiences to target Using customer data for seasonal marketing means mapping behavior to intent. This core tactic in customer database marketing can help you drive deeper engagement. Our data solutions simplify the process, whether you’re starting with limited data or already know your best customers. If you’re starting with a list, Enrichment can append lifestyle, income, and travel preference data to help you understand what motivates your existing customers. If you don’t have a list, Marketing Attributes gives you full control when building new audiences or lookalikes based on relevant seasonal traits like beach vacationers or frequent CTV watchers. 3. Identify key holidays and events Summer is full of shopping triggers: Memorial Day, Father’s Day, Fourth of July, Labor Day, and countless local and regional events. However, not every customer behaves the same way. Use Enrichment to understand when your customers are most likely to act. By comparing your first-party data to broader market segments, you can time promotions more strategically. For instance, enrichment might reveal that outdoor gear buyers convert in early June, while luxury travelers plan closer to July. 4. Activate across digital, TV, and retail media Summer shoppers don’t stick to one screen. They’re streaming TV, reading travel blogs, browsing retail apps, and catching up on email — often from a beach chair or airplane seat. That’s why omnichannel delivery is a must, and it’s where consumer data vendors like Experian can help you reach your audience across channels with targeted messaging for key holidays and events: Syndicated Audiences simplifies omnichannel activation with built-in integrations to 30+ leading activation platforms. These pre-mapped segments let you deliver consistent messaging across the places where your audience is most engaged. Looking for privacy-forward reach? Contextually-Indexed Audiences are segments built by linking real-world behavioral data to the types of content those audiences typically consume online, allowing you to activate based on content instead of identity while offering a more contextually relevant experience. Using customer data for seasonal marketing, Experian maps real audience segments across web and app environments — like national park guides and travel blogs — for ID-free precision targeting in a cookieless environment. 5. Track and evaluate performance Don’t wait until the end of the campaign to make changes. Experian’s measurement tools help you track performance in real time, so you can optimize early and often. Measure how well specific audiences — enriched, syndicated, or contextual — are performing across platforms and use those insights to shift spend toward top performers. 6. Optimize and refine your strategy After the season ends, it's time to take what you’ve learned and build smarter for the next push. Use Outcomes to analyze: Who converted Which segments underperformed How your customer base compares to the broader market How your audience evolved Which campaigns drove meaningful adoption These insights can then inform your next round of audience building, so whether it’s back-to-school or a holiday, you’re already ahead. Example 1: The beach vacation shopper To illustrate Experian’s Audience solutions at work, let’s say a high-end swimsuit brand wants to reach women over 30 planning beach vacations to Florida, Hawaii, or Mexico. However, their CRM only includes basic transaction and purchase details and offers little insight into who their customers are. Audience solution: Enrichment Using Experian’s Enrichment solution, the brand could layer on lifestyle, income, and travel preference data to turn shallow profiles into rich audience segments. With a deeper understanding of their shoppers, the brand could develop a targeted messaging strategy by destination, build high-performing lookalike audiences, and confidently activate across channels. Example 2: The European traveler As another example, suppose a footwear brand wants to reach millennial travelers heading to Europe between May and August. They specialize in stylish, comfortable walking shoes that are ideal for travel but lack the technical in-house resources to build custom segments. Audience solution: Syndicated Audiences Using our Syndicated Audiences, the brand could easily tap into pre-built segments tied to leisure travelers, international shoppers, and comfort-focused footwear buyers. With plug-and-play access to over 2,400 verified audience segments, the brand could quickly layer this targeting into their programmatic and paid social campaigns without requiring custom development. And with fast speed-to-market and improved message relevance, the brand could launch cross-channel campaigns just in time for peak summer travel planning. Example 3: The outdoorsman Consider a camping tent company that wants to reach families planning summer trips to national parks, campgrounds, or RV resorts. They don’t have much first-party data to work with, but they know their audience is online, researching their next adventure. Audience solution: Contextually-Indexed Audiences With Experian’s Contextually-Indexed Audiences, the brand could target people actively reading content about outdoor travel (like hiking tips, campground reviews, or road trip itineraries) without relying on cookies or IDs. They’d be able to activate contextually relevant audiences mapped to sites that outdoor enthusiasts frequent and drive site traffic with strong click-through rates. Example 4: Big-box retailer launching summer gear Imagine a national retailer preparing to promote summer essentials like patio furniture, grills, fitness gear, and travel accessories. Their goal is to build predictive models for their summer product demand and reach new customers most likely to buy before they even search. Audience solution: Marketing Attributes With Experian’s Marketing Attributes, the retailer could license over 5,000 lifestyle, demographic, and behavioral variables to enrich internal models and uncover high-indexing consumer groups, such as outdoor entertainers or health-conscious families. This data-powered insight would help them predict demand and identify audience segments worth testing across media channels. The team could find new, qualified segments ideal for email and CTV activation and get a head start on the season, eventually increasing ROI on their summer campaign spend.
