By integrating Experian's Digital Graph and Offline Identity Resolution, Infillion strengthens identity connections, improves campaign reach, and enhances audience engagement across CTV, mobile, and web.In our Ask the Expert Series, we interview leaders from our partner organizations who are helping lead their brands to new heights in AdTech. Today’s interview is with Ben Smith, VP of Product, Data Products at Infillion.
Adapting to signal loss
What does the Experian–Infillion integration mean for advertisers looking to reach audiences as signals fade?

As cookies and mobile identifiers disappear, brands need a new way to find and reach their audiences. The Experian integration strengthens Infillion’s XGraph, a cookieless, interoperable identity graph that supports all major ID frameworks, unifying people and households across devices with privacy compliance, by providing a stronger identity foundation with household- and person-level data. This allows us to connect the dots deterministically and compliantly across devices and channels, including connected TV (CTV). The result is better match rates on your first-party data, more scalable reach in cookieless environments, and more effective frequency management across every screen.
Connecting audiences across channels
How does Experian’s Digital Graph strengthen Infillion’s ability to deliver addressable media across channels like CTV and mobile?

Experian strengthens the household spine of XGraph, which means we can accurately connect CTV impressions to the people and devices in that home – then extend those connections to mobile and web. This lets us plan, activate, and measure campaigns at the right level: household for CTV, and person or device for mobile and web. The outcome is smarter reach, less waste from over-frequency, and campaigns that truly work together across channels.
The value of earned attention
Infillion has long championed “guaranteed attention” in advertising. How does that philosophy translate into measurable outcomes for brands?

Our engagement formats, such as TrueX, are based on a simple principle: attention should be earned, not forced. Viewers choose to engage with the ad and complete an action, which means every impression represents real, voluntary attention rather than passive exposure. Because of that, we consistently see stronger completion rates, deeper engagement, and clearer downstream results – like lower acquisition costs, improved on-site behavior, and measurable brand lift.
To take that a step further, we measure attention through UpLift, our real-time brand lift tool. UpLift helps quantify how exposure to a campaign influences awareness, consideration, or purchase intent, providing a more complete picture of how earned attention translates into business impact.
Creative innovation and location insights
Beyond identity resolution, what are some of Infillion’s capabilities, like advanced creative formats or location-based insights, that set you apart in the market?

One key area is location intelligence, which combines privacy-safe geospatial insights with location-based targeting through our proprietary geofencing technology. This allows us to build custom, data-driven campaigns that connect media exposure to real-world outcomes – like store visits and dwell time – measured through Arrival, our in-house footfall attribution product.
We also build custom audiences using a mix of zero-party survey data, first-party location-based segments, and bespoke audience builds aligned to each advertiser’s specific strategy.
Then there’s creative innovation, which is a major differentiator for us. Our high-impact formats go beyond static display, such as interactive video units that let viewers explore products through hotspots or carousels, rich-media ads that feature polls, quizzes, dynamic distance, or gamified elements, and immersive experiences that encourage active participation rather than passive viewing. These creative formats not only capture attention but also generate deeper engagement and stronger performance for a variety of KPIs.
Future ready media strategies
How does Infillion’s ID-agnostic approach help brands future-proof their media strategies amid ongoing privacy and tech changes?

We don’t put all our eggs in one basket. XGraph securely unifies multiple durable identifiers alongside our proprietary TrueX supply to strengthen CTV household reach. This agnostic design allows us to adapt as platforms, regulations, and browsers evolve – so you can preserve reach and measurement capabilities without getting locked into a single ID or losing coverage when the next signal deprecates.
Raising the bar for media accountability
Looking ahead, how is Infillion evolving its platform to meet the next wave of challenges in audience engagement and media accountability?
From an engagement standpoint, we’re expanding our ability to support the full customer journey, offering ad experiences that move seamlessly from awareness to consideration to conversion. That includes smarter creative that adapts to context, intelligent targeting and retargeting informed by real data, and formats designed to drive measurable outcomes rather than just impressions.
When it comes to accountability, we’re ensuring that measurement is both flexible and credible. In addition to our proprietary tools, we partner with leading third-party measurement providers to validate results and give advertisers confidence that their investment is truly performing. Within our DSP, we emphasize full transparency and log-level data access, ensuring advertisers can see exactly what’s happening on every impression.
All of this builds toward the next era of agentic media buying – one enabled by our MCP suite and modular, component-based tools. This evolution brings greater accountability and next-generation audience engagement to an increasingly automated, intelligent media landscape. Our goal is to help brands connect more meaningfully with audiences while holding every impression – and every outcome – to a higher standard of transparency and effectiveness.
Driving impact across the funnel
What is a success story or use cases that demonstrate the impact of the Experian–Infillion integration?
We recently partnered with a national veterans’ organization to raise awareness of its programs for injured or ill veterans and their families. Using the Experian integration, we combined persistent household- and person-level identifiers with cross-device activation to reach veteran and donor audiences more precisely across CTV, display, and rich media. The campaign achieved standout results – industry-leading engagement rates, a 99% video completion rate, and measurable lifts in both brand awareness (3.6 % increase) and donation consideration (13.7% lift). It’s a clear example of how stronger identity and smarter activation can drive meaningful outcomes across the full funnel.

Originally appeared in AdExchanger Navigating the world of data and identity partners feels like scrolling through a dating app: a sea of options, but only a select few worth swiping right. To find your perfect match, look for a partner who ticks all the right boxes. Here’s your guide to finding your perfect match. 1. Identity resolution: It all starts with a strong foundation Great identity resolution depends on a rock-solid foundation. The best partners rely on offline data—like names, addresses, and emails—that rarely change, ensuring a consistent view of households, individuals, and their devices over time. You want someone who gives you the same understanding of your audience across every stage of a campaign. 2. In search of: A well-rounded, reliable identity partner When evaluating identity graphs, it’s essential to distinguish between digital-only graphs, offline graphs, and those rare gems who combine both. Digital graphs rely on digital identifiers, while offline graphs are grounded in persistent identifiers like name, address, and phone number. A partner who offers both creates a more complete and reliable view of consumers across channels, resulting in more effective targeting and measurement. 3. Match rates are like dating profiles—don’t be fooled by the numbers Match rates can look impressive, but they’re often misleading. They can also vary widely depending on the methodology and the IDs being tested. Some providers inflate match rates by limiting the scope of comparison or tweaking their standards. The real indicators of quality are the depth of the data, the quality of matches, and how often the graph is refreshed. Ideally, your partner updates their graph weekly or monthly. The inclusion of inactive IDs may inflate the perceived scale without reflecting the true addressable audience. It's like having a profile photo from ten years ago–a major no-no. 4. Authentic origins: Is their data genuine or just a catfish? Look into your partner’s data sources and place a premium on those with public records or direct to consumer relationships. Ask if they have the experience and expertise when it comes to all aspects of data processing from accuracy to privacy and security. Look for some clear third-party indicators for accuracy, like ratings from Truthset, but there is also a basic reality: either your partner is focused on privacy and accuracy, or they are just playing the scale game. Swipe left on those playing games. 5. The breadth to impress Depth matters as much as quality. Seek a partner with wide-ranging attributes that span key audience categories like demographics, interests, and purchase behavior. They should offer the flexibility to deliver both granular data scores and broad audience segments, empowering you to reach the right consumers across channels effectively. 6. The total package: Does your partner really have it all? A true, lifelong partner connects the dots seamlessly, offering a blend of data and identity that link households to devices while layering in rich marketing insights. This approach helps advertisers better understand their customers, reach the right audiences across channels, and measure the impact of their campaigns. The right partner is well-connected and ensures that all the pieces—identity, data, and activation—work in harmony. 7. Future-proof charm: Will they ghost you when cookies crumble? With the Identifier for Advertisers (IDFAs) gone, cookies on the wane, and IP addresses under scrutiny, a partner’s ability to adapt is critical. The most future-proofed solutions are based on offline identifiers like names and addresses, which are user provided and consented data points–making them more resistant to privacy changes. Additionally, look for partners who have made the necessary investments and are prepared to support the new wave of addressable IDs emerging as alternatives to traditional signals. 8. Privacy savvy: Do they respect boundaries? As privacy laws evolve, you need a partner with a strong history in privacy compliance and proactive leadership in navigating new regulations. Strong and transparent privacy policies and participation in privacy organizations are a good indicator of trustworthiness, especially as new rules emerge across different states. Look for a partner who takes data privacy as seriously as you do and gives you peace of mind when handling sensitive information. 9. Seamless connectivity: Do they play well with others? Data is only as useful as it is actionable. Connectivity across platforms is essential, so choose a partner with seamless integrations into the major platforms you rely on for advertising. This ensures your data quality and identity resolution remain intact throughout your campaigns, avoiding loss from multiple handoffs. 10. Killer customer service: Are they in it for the long haul? A great partner collaborates to solve challenges, not just to sell or upsell. Long-standing partnerships and testimonials about strong customer service are key indicators of reliability. Choose a partner who educates and guides you through technical and strategic challenges, fostering an environment where problem-solving and innovation thrive. Keep your standards high Only a handful of companies can meet these rigorous criteria, and you should refuse to settle for a partner that lacks any of these key dimensions. Successfully navigating signal loss, privacy compliance, and seamless omnichannel integration requires extensive resources, robust infrastructure, and years of expertise.

Delivering personalized customer experiences is essential, with 81% of customers preferring a personalized approach to their relationships with brands. However, 80% of consumers are concerned about how their data is used, presenting businesses with the challenge of balancing data collection and privacy with personalization. Despite consumer appetite for personalization, many organizations lack the data to make data-driven decisions: 68% of businesses don't understand how their customers think, and 82% don't confidently know their customers' pain points. Without this critical data, businesses cannot effectively create personalized consumer connections. Experian offers businesses robust and unique data through our Marketing Attributes to empower businesses with the insights required to derive accurate insights into consumers and drive personalized experiences.

Reach a new segment of the market for a new product offering Introducing a new product to a new segment of the market presents unique brand challenges. Without any historical customer data to draw upon, companies lack vital insights that could help them identify and reach their target audience. This absence of foundational knowledge makes it challenging to understand consumer preferences, craft suitable messaging, or determine the most effective channels for connecting with potential customers. To navigate these hurdles, brands frequently turn to Marketing Attributes for consumer research within the new segment.

Setting sail For hospitality and travel marketers, understanding which marketing efforts lead to actual bookings can be a tidal shift. Windstar Cruises—renowned for its intimate yachts and off-the-beaten-path itineraries—wanted data-driven visibility into how digital media placements translated into confirmed reservations. Windstar turned to the strategic media expertise of MMGY, a leading integrated marketing company dedicated to the travel, tourism, and hospitality industries and Experian's marketing data and identity solutions to bridge this gap. Together, they developed a closed-loop attribution system that directly tied digital campaigns to offline passenger bookings. The challenge: Blind spots in the booking journey Windstar Cruises had plenty of top-of-funnel metrics—impressions, clicks, website sessions, cruise quote requests—but struggled to connect these indicators to confirmed reservations. Without that link, it wasn't easy to pinpoint which audience segments were most valuable in their marketing campaigns or accurately measure return on ad spend (ROAS). Traditional attribution methods and limited booking system data painted an incomplete picture, leaving Windstar to wonder which media channels and audience strategies were truly driving revenue. MMGY and Experian: Bridging data gaps to power attribution Comprehensive pixel tag MMGY designed an online-offline measurement strategy and coordinated with Experian to deploy pixels across Windstar's digital media placements. These pixels captured valuable event-level data—ad exposures, clicks, site visits, and more—so that every interaction could be matched back to a future booking if it occurred. Identity resolution and data enrichment Using the Experian identity graph, Experian matched Windstar’s reservation data with its extensive consumer database. This approach provided a precise, individual-level view of how digital interactions translated into real-world sales. By combining pixel data (which identifies who viewed specific ads) with reservation data (which shows who ultimately made a booking), the solution delivered a comprehensive, end-to-end, multi-touch perspective on the customer journey. Advanced audience segmentation Utilizing MMGY’s powerful Terminal audience modeling platform—which integrates MMGY Travel Intelligence performance and intent data, Experian’s consumer intent data, and the client’s first-party data— MMGY in conjunction with Experian’s marketing analytics team developed custom audiences designed to drive incremental traveler growth. These audience segments identified travelers most likely to engage in the unique travel experiences Windstar offers. The insights revealed not only who these travelers are, but also where they consume media, how they make travel decisions, and what influences their purchasing behavior. This data guided the development of hyper-targeted media buys, ensuring Windstar’s messaging reached the right people on the right platforms at the right time—maximizing engagement and driving qualified leads. The results: Mapping spend to bookings By utilizing data connectivity and measurement, Windstar gained the insights needed to optimize every aspect of its marketing—audiences, media placements, channels, and more. This data-driven approach revealed which tactics were most effective and enabled Windstar to refine campaigns in real-time for maximum impact. 6,500+ bookings attributed to digital efforts: Over 6,500 bookings—valued at over $20 million—were tied to specific MMGY-managed placements, demonstrating which data-driven tactics led passengers to book. This level of attribution was only possible because we helped Windstar measure and connect the right data points. 13:1 ROAS: By investing $1.48 million in highly trackable, data-informed media, Windstar achieved an impressive 13:1 return on ad spend. Data connectivity gave Windstar the clarity needed to target the right audiences and channels—turning every $1 of spend into $13 of bookings. Actionable cost per booking benchmark: Armed with the ability to map ad spend to individual bookings, Windstar’s average cost per booking settled at $236. With insight into which audiences and placements performed best, Windstar adjusted its strategy in real-time, lowering acquisition costs across the board. High-value reservations: Attributed bookings were, on average, $500 higher in value than non-attributed bookings. By focusing on the right customer segments and messages—determined through precise measurement and segmentation—Windstar secured more bookings and maximized revenue per guest. Terminal Audiences outperformed: For Terminal-targeted segments, the ROAS soared to 28:1 with nearly half the cost per booking compared to non-Terminal audiences. This outcome illustrates how advanced data segmentation and connectivity deliver more profitable guests at lower acquisition costs—further proof that continuous optimization grounded in real data pays off. What this means for travel and hospitality Windstar's success story illuminates a bigger truth for the travel and hospitality industry: closing the attribution loop is no longer optional. In a fiercely competitive marketplace, brands need concrete proof that their marketing investments drive awareness and translates into real revenue. By marrying MMGY's travel-specific marketing acumen with Experian's marketing data and identity solutions, travel brands can: Invest with confidence: Marketing investment flows to the most effective channels and placements based on actual bookings, not superficial metrics. Refine strategies: Real-time attribution data creates a feedback loop marketers can use to iterate on messaging, creativity, and targeting for even stronger results. Capture higher-value guests: Pinpointing and appealing to likely travelers allows marketers to increase booking volume and total revenue per booking. Charting a course for data-driven success By seamlessly linking digital exposure to confirmed reservations, Experian and MMGY gave Windstar Cruises the compass they needed to navigate the complexities of digital marketing confidently. This new level of insight is empowering Windstar to double down on the campaigns, creatives, and segments that move the needle the most. For travel and hospitality brands worldwide, data-driven attribution goes beyond simply understanding what happened—it’s about shaping what comes next. When marketing decisions are guided by real customer journeys and precise ROI metrics, brands can make more innovative investments, foster stronger guest relationships, and chart a course toward sustainable growth.
