Collaboration solves programmatic challenges
Could you share the story behind the partnership between OpenX and Experian and how this collaboration differs from typical data-provider/DSP or SSP relationships in the market? What unique challenges in programmatic advertising does this partnership solve?
OpenX first partnered with Experian in 2019 when we were building the industry’s first data-driven supply-side curation platform. Being the only SSP with a proprietary people-based identity graph (further enriched by Experian) gives OpenX a unique set of capabilities that are only growing in value in the market. We are seeing retail media networks, large agency planning platforms, and indie and specialty shops lean into OpenX’s tools to match, activate, and measure people-based audiences through our robust curation platform and premium supply.
Enhancing campaigns with data enrichment
How does combining Experian’s marketing data with OpenX’s technology create tangible benefits for advertisers, agencies, and publishers?
Last year, we expanded our partnership with Experian to enrich our digital IDs with Experian’s Digital Audiences, essentially making Experian data available directly to marketers across all OpenX supply and formats, including CTV. For marketers, this direct integration increases both match and activation rates. Meaning, not only do we match more of the starting audience universe to our system, we then provide more opportunities to identify and transact on those users in the bidstream. The result is greater reach for buyers even in previously unaddressable environments like Safari or mobile web – and publishers benefit from the increased addressability OpenX provides their supply.
Delivering impactful inventory solutions
OpenX has been enhancing its curation offerings beyond just providing curated marketplaces. Could you describe the strategic shift you’re making in how you package and deliver inventory?
At OpenX, we have a broader and more dynamic view of curation. It’s not just about gathering data or bundling inventory; it’s about layering on identity-based precision, enabling the targeting of the right audiences with premium, brand-safe inventory for our clients.
We saw the value of curating inventory and audiences on the supply side early on. We started by building capabilities for our own exchange and then found that our approach created tremendous value for data owners and marketers alike. Over the past five years, we’ve been continuously investing our curation platform capabilities to super serve those partners. As a result, we have what we think is by far the most robust and flexible platform in the market. We can match and integrate with any kind of data, curate supply at a granular level, activate audiences and help measure outcomes in multiple ways. We also provide turnkey integrations to third-party platforms.
Balancing customization with scalability in deals
There’s often tension between customization and scalability when it comes to curated deals. How does OpenX strike the right balance to meet varied advertiser objectives while ensuring operational efficiency for publishers?
Truthfully, we’re not finding that scale suffers with curation. We currently have 237 million monthly active users in our exchange that we can match and activate curated deals against. That’s a unique claim for an SSP, and we back it up with our identity graph. This directly benefits our publishers who see a 20% increase in overall bid density and a 118%+ increase in win rate for curated deals vs. open market.
Data-driven curation done on the supply side offers efficiency and drives results for buyers, while publishers are able to activate their own first-party data programmatically, increase their monetization, and maximize the value of their inventory. As the industry continues to adapt to a privacy-first, consent-based ecosystem, data-driven curation will play a key part in ensuring both sides of the marketplace continue to thrive.
Driving results with CTV curation
Connected TV is arguably the most dynamic channel in programmatic right now. How do curation improvements accelerate more precise or outcome-based targeting in CTV environments?
I want to take this a step further and say that biddable is the future of CTV. Not only does biddable enable advertisers to purchase closer to campaign activation, it gives buyers the option to curate deals, flexibility, addressability and ease of transacting at will. No minimums, no commitments.
Our CTV strategy has been centered around combining flexibility, efficiency, and real-time optimization capabilities with access to premium, direct, glass-on-wall inventory. TV by OpenX, powers the direct activation of curated audiences at scale through data-driven, contextual, attention, and sustainability offerings.
What does this mean for buyers? Advertisers can choose from any one of OpenX’s 250+ data partners, including Experian, to target an audience via CTV inventory using OpenX’s cross-platform identity graph. This setup allows buyers to increase scale and optimize toward their desired campaign outcomes via their preferred DSP. The focus on inventory quality and scale combined with advanced targeting curation provides a key driver of performance in CTV.
Identity resolution for better CTV measurement
In a channel as fragmented as CTV, measuring performance can be complex. What role does identity resolution play in better measurement and attribution? How do Experian’s identity capabilities integrate within your platform to drive measurable outcomes?
We talked about the value of audience targeting via curation above. Another critical driver is our ability to power true closed-loop measurement for advertisers or partners like retail media networks. OpenX is able to provide automated log-level reporting via BIDS, which includes exposed IDs from our proprietary ID graph back to our partners in near real time.
This closed-loop attribution enables partners to measure real-world outcomes like ROAS, conversion rates and incrementality. Insights and learnings from data can then be used to make optimizations mid-campaign, to further improve performance. Measurement starts with having a strong foundation to identity resolution – which Experian helps us achieve.
Tailoring audience strategies in the auto sector
The automotive vertical demands highly specific audience insights—everything from in-market signals to lifestyle and aftermarket service and parts data. How does the Experian–OpenX partnership enhance audience strategies in auto?
Experian’s deterministic data, combined with the OpenX identity graph, empowers buyers with identity tools to create targeted audience segments of likely auto intenders. For verticals that have high customer acquisition costs like auto, these insights are particularly valuable, as buyers often struggle to identify their audiences at scale in environments that drive campaign performance.
Experian’s automotive data is one of our most requested audiences from buyers. We match Experian’s high-quality data directly to our platform, often leveraging Experian’s IDs, which leads to greater scale and fidelity. In addition, our platform can curate supply to a granular level to drive results for buyers.
Complying with evolving privacy regulations
With data privacy regulations multiplying—like GDPR, CCPA, and others—how does OpenX’s direct connection with Experian ensure responsible data usage and compliance?
At OpenX, we don’t see privacy regulations as a challenge but rather an opportunity. Instead, it’s a key differentiator for us. We’ve had a strong focus on data and identity since 2017, and we believe that if you’re talking about these topics but not talking about privacy, you’re missing an important piece of the equation.
Regardless of the environment — CTV, mobile, app, or web — in today’s privacy-focused world, success in data and identity is inseparable from a commitment to privacy. We support this obligation with dedicated leadership that helps our partners navigate evolving global regulations, including critical areas like child-directed content under new laws from Australia to Maryland.

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 deliver deep customer insights With Experian, you go beyond surface-level data.

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. Increase scale: By matching first-party data to multiple universal IDs, MiQ expanded its reach across devices, contributing to a 51% increase in seed audience reach and and a 64% increase in reaching using universal IDs. Improve efficiency: The combination of Experian’s data with MiQ’s Identity Spine improved cross-device ID resolution, leading to more accurate measurement and reporting with a 70% match rate in associating MiQ-provided IP addresses with universal IDs.

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.
