As CTV viewership grows, marketers face challenges in targeting and measurement across fragmented platforms. Identity resolution and audience strategies, supported by Experian’s syndicated audiences and privacy-safe solutions, help DSPs and advertisers reach high-value audiences, improve campaign accuracy, and drive measurable outcomes.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 George Castrissiades, General Manager of Connected TV at AdRoll.
Premium reach and fragmentation
As viewer attention fragments across platforms, how should marketers redefine “premium reach” in CTV to prioritize engagement and audience quality over scale alone?

A few years ago, ad supported streaming over-indexed on younger adults, those without much financial history and much more budget conscious. It would have been fair for B2B brands to assume that maybe they weren’t going to find their C-Suite audiences on those channels, and so connected TV(CTV) was positioned as a top of funnel tactic aimed at retail. But that’s all changed – ad-free prices are going up, and ad supported tiers are the norm across the majority of channels. 66% of adults have at least one ad supported streaming channel, and adults today spend nearly as much time streaming movies and TV as they spend on their mobile phones. Now that ad viewing audiences on CTV really span the full spectrum of demo, techno, and firmographic segments, savvy marketers should partner with platforms that offer breadth and depth of targeting and measurement to find the highest value audiences wherever they’re watching CTV and serve them highly relevant ads that draw their attention towards the screen. I know I’m jumping out of my seat whenever I see an AdTech or MarTech ad.
Identity and relevance
What does a strong identity framework unlock for delivering household- and person-level relevance across screens, and how does it reshape audience planning?

In privacy-safe ecosystems, people want to share less data and log in to websites and browsers less frequently. If you can’t resolve a household ID to a CTV device through Safari and other sources of obfuscated identity, you’re going to end up losing a lot of signal along the way. On top of that, targeting smaller, higher-value audiences means this attrition can have a profound impact on your ability to build meaningful reach and use audience forecasts to predict scale. A strong identity framework is the key to maintaining as much of your planned audience as possible and staying true to initial forecasts.
AI and outcome planning
How is AI evolving CTV from tactical bidding to strategic outcome planning, and what mechanisms are in place to validate true performance lift?

Tomorrow isn’t guaranteed, especially not in advertising. Audiences change where and when they consume media, and so shifting budget to a placement that did well yesterday is like buying a stock when it’s outperforming – the gains might be gone by then! Predictive AI is bridging the gap to find the highest value and most engaged audiences in real time, versus being purely reactive. This helps drive outcomes which we see in the form of pipeline influence, ROAS, and site traffic lift – without exponentially increasing costs. The same is true for account-based marketing(ABM) outcomes – there’s a blend of signals, account “fit” and intent data that needs to be evaluated in a deeper, more intelligent way. AI is helping to find those highest value accounts, even before they’re in market, which means smart marketers aren’t showing up late to the party.
Measurement and incrementality
What privacy-safe, closed-loop measurement frameworks should become standard to prove incremental visits and sales from CTV campaigns?

Working with a dedicated multichannel, full-funnel ad and marketing platform like AdRoll can easily let you know when a user arrives at your site and makes a purchase, but understanding how that customer arrived there and which tactics deserve the credit requires a deeper, more sophisticated workflow. Our partnership with Experian allows all devices in a household to ladder back up to a household ID, so we can ensure accuracy without pivoting on anything personally identifiable. This works perfectly in CTV, an environment that follows an app workflow of user resettable device IDs rather than IP address or email but always connects seamlessly to web tokens including cookies. Accuracy, scale, and privacy are maintained in a proven way – you see this tech underpinning the infrastructure of streaming across all the biggest players, so marketers can rest easy.
Creative and commerce
How can creative sequencing and shoppable TV experiences convert living-room attention into commerce without compromising user experience or feeling intrusive?

I like to say that CTV trades attention for action. Users lean back and focus on the messaging and visuals of the big screen rather than scrambling for the mouse or tapping to close some intrusive pop-up. This focus means that the messaging is absorbed more quickly, but creatives can wear out their welcome just as fast. Sequential messaging really helps to move the messaging along without subjecting the viewer to longer ads where attention wanes, but also increases brand recall and specific product information because the story evolves with each impression. This is a great tactic to use when you want a viewer to take a specific action later – but shoppable ads can help motivate a user to act now, and new formats can really simplify things. Shoppable can feel out of range for most – the top players in this space own major e-comm storefronts and then tie them back into their own demand-side platforms (DSPs), content, and streaming devices. For the rest of us, dipping our toes in slowly through simple and cheap solutions like QR codes can connect audiences right to a web experience from their TVs, or intermediate solutions like interactive video ads. Users love to play around with fun on-screen experiences, and there’s a whole spectrum of crawl/walk/run options available.
Trust and governance
Which shared guardrails—brand safety, fraud control, and frequency management- are essential to unlocking sustainable, scaled investment in CTV?

I’ve always thought of CTV inventory analogously to high-end watches – if you buy from the source or a well-known, reputable dealer, you’re probably buying the real thing. But that fancy timepiece the guy was selling outside the bar, that you swore looked real? Probably not. Untrusted resellers and too-good-to-be-true pricing might mean you’re running ads on a screen at a lonely gas station at 3 am to an audience of no one, and that’s not even the worst case scenario. Good relationships and deep pockets can solve brand safety and fraud issues, but not every advertiser is going to have those resources. Brand safety and fraud prevention can reduce workload and help distinguish the good stuff from the growing pool of gray area, arguably, CTV inventory that isn’t what was promised to a customer. Outsourcing this trust also goes a long way, with buyers knowing you’re not grading your own homework. Frequency management is equally as important. Once you have your audience and your good supply, it’s important not to abuse a single household just because they meet your targeting criteria. Reach is your best friend with CTV.
Data and audience strategy
How do Experian’s syndicated audiences provide a consistent, scalable foundation for planning, activation, and measurement across CTV and digital, and what outcomes are clients seeing?

We love to talk about how Experian’s data is such an integral part of so much of streaming’s architecture, and the fact that it’s built on deterministic datasets means you’re getting scaled audiences built on knowledge rather than best guesses. That means a lot when working across multiple channels, privacy-safe environments, and households with an ever-growing number of connected devices. Our customers are always delighted at how precise targeting can be, especially in the B2B/B2C space – and knowing the size of those audiences helps them to understand how budget transforms into reach in a more predictable way. It’s confidence-inspiring to point to a new audience and tell your client that these are their future customers. The best part is showing them the outcomes reporting – we consistently see a massive spike in site traffic and engagement on days when a new Experian syndicated audience is launched!

Retail media networks (RMNs) rank among the fastest-growing media channels. According to eMarketer, retail media spend is forecasted to account for more than a fifth of overall digital spending in 2025, and retail media spend will grow by 21.8%. For RMNs, the path to realizing this opportunity is marked by navigating through a series of critical stages, each with its own set of challenges and solutions. Retail media strategies Simply put, RMNs need to know who their customers are, where they are, and how to reach them to succeed. But we know nothing is that simple. This blog post reviews the three pivotal stages of RMN success, offering a roadmap for networks aiming to optimize their operations and claim their share of the rapidly growing category. Stage 1: Develop a data foundation In a world where traditional tracking methods are fading, first-party data has become essential for targeted advertising. Retailers have a wealth of this valuable data due to their direct consumer relationships. The initial step in establishing an RMN is to organize and utilize this data effectively. Steps to develop a data foundation: Organize data: Bring together fragmented shopper data, loyalty program information, and other customer data into a unified location. Clean and deduplicate this data to create consistent customer profiles. Enhance profiles: Gain insights into your customers and your brand’s customers so you can learn who your best, lapsed, and non-customers are. Append additional attributes to your shopper data, including media consumption habits, lifestyle preferences, demographic information, and more. Use identity graphs: Identity providers, like Experian, enable you to learn about the anonymous – and known – visitors on your platform and organize disparate customer data points into households. This will allow RMNs to connect addressable identifiers to the household, making it easier to reach customers across channels. Create audience segments: With a solid data foundation, RMNs can build audience segments beyond basic shopper data. These segments will make your data more attractive and actionable for media buyers. For example, consider a retailer that knows its shoppers are primarily young professionals, but a CPG brand wants to target not only these shoppers but also young professionals who are parents. By partnering with an identity solution provider like Experian, the retailer can append additional data to identify and target the young parents within their existing customer base, enabling the CPG brand to reach both audience segments effectively. “Retail media networks thrive on clean, accurate, and actionable data. Simply put, it's crucial to know who your customers are, when they're most engaged, and where to reach them to drive effective marketing strategies and maximize ROI.”anne passon, sr. director, sales, retail Stage 2: Become a publisher for optimal retail media growth The next step for RMNs is to transition from building a data foundation to helping marketers reach their target audience, essentially becoming a publisher. This involves two main processes: organizing advertising inventory and connecting it to demand. Steps to become a publisher: Audit and organize inventory: Conduct a thorough review of all existing ad spaces, including websites, apps, and in-store placements. Identify gaps and consider creating new advertising opportunities, such as website and app features, interactive digital experiences, or expanded in-store touchpoints. Connect inventory to demand: Integrate the organized inventory with platforms, allowing advertisers to access it easily. This often involves using supply-side platforms (SSPs) and demand-side platforms (DSPs). Continuing with our example, the CPG brand can work with its DSP or SSP partners and easily access your ad inventory, and effectively target the young professional and young parent audience segments. Stage 3: Scale inventory for retail media growth As RMNs progress to the final stage of their success journey, they may face the challenge of limited inventory within their owned and operated (O&O) channels. To meet marketers' expansive reach requirements and to continue to drive growth and profitability for their organizations, RMNs must expand their inventory beyond O&O. Steps to scale inventory: Utilize data collaboration tools: Clean rooms allow secure merging and enrichment of data from various sources, creating richer audience profiles while maintaining privacy. Resolve identity and enhance addressability: Identity graphs help resolve known customer identifiers (e.g. emails) into addressable IDs (e.g. mobile IDs and connected TV IDs), which can be used to reach customers across all the platforms they consume media. Expand audience reach: Onboarders, like Experian, help extend data and audiences to programmatic destinations beyond a retailer's O&O inventory. By mapping audiences to digital identifiers maintained by identity partners, RMNs can significantly widen their reach, meeting advertisers' needs for engaging with broader and more diverse audience segments. The CPG brand can now reach young professionals and young parents on the retailer’s platform and in all the other places where they consume media, like watching their favorite shows on connected TV (CTV) or browsing the web on their phones. Measurement across stages for retail media growth Measurement is crucial and must be conducted during and after a campaign to understand and validate performance. Here are two types of measurement to consider: Cross-device campaign measurement: Measure performance by connecting an ad exposure in one environment (e.g. CTV) to an action in another (e.g. mobile purchase). This holistic, cross-device approach requires a partner for identity resolution as it will ensure that the impact of a campaign is fully understood. Aggregate performance analysis: Understand performance in aggregate across several campaign studies. Receive independent third-party measurement validation that you can promote to advertisers to drive increased spend. For our CPG brand, these measurement reports ensure that they can track the performance of their campaigns from the initial exposure on a CTV to the final purchase made on a mobile device, providing comprehensive insights and validation of their advertising strategy. The retailer can aggregate these studies and promote their network’s effectiveness to prospective advertisers. Accelerate retail media growth with strategic partnerships The journey through the stages of RMN success is riddled with deep technical challenges that are often beyond the institutional capabilities of non-media businesses. The intricacies of data management, audience insights, identity resolution, precise cross-device targeting, and measurement require specialized expertise and technologies that may not be readily available in-house. RMNs stand to benefit from forging strategic partnerships with companies that possess not only the necessary technological tools but also a profound understanding of the media landscape. The steps outlined here will accelerate your growth and ensure you capitalize on the opportunity in front of you.

Get ready for Cannes Lions 2024—the advertising industry is buzzing with excitement. This year's event promises to be a center of innovation, ideas, and networking. Here are five themes we expect will take center stage in conversations and how Experian can help marketers be prepared for what’s ahead. Cookie deprecation and signal loss At Cannes Lions 2024, the theme of transitioning to a cookieless advertising ecosystem is likely to dominate discussions. The saga of cookie deprecation continues to unfold, with Google recently pushing back the demise of third-party cookies once again. Experian remains fully committed to prioritizing continued testing of different industry solutions, including the Google Privacy Sandbox, to help customers prepare for a future without cookies. We've identified six viable alternatives to third-party cookies, how these alternatives fall short, and how Experian can help you navigate these alternatives. With Experian, the loss of cookies does not equate to a loss of coverage. With our strong roots in offline data and significant investments in our Graph, Experian ensures uninterrupted and effective marketing with robust signal coverage, with or without cookies. Based on early tests, we expect our Graph to maintain 97% of its household coverage. Read how MiQ, a leader in the cookieless era, strengthened its Identity Spine with the integration of Experian’s cross-device Graph here. Commerce The theme of commerce is poised to be a central topic of discussion at Cannes Lions 2024, reflecting the emergence and growth of retail media networks (RMNs). Evolving customer expectations are a key driver, with consumers demanding seamless and personalized experiences across all touchpoints of their shopping journey. The importance of bridging physical and digital experiences to create a cohesive customer journey will undoubtedly feature prominently in discussions at Cannes. Experian's Consumer Sync offerings facilitate seamless integration between online and in-person interactions, fostering a cohesive approach to engaging audiences across various platforms while measuring campaign effectiveness. As we heard at Shoptalk 2024, the evolution of retail media is propelling us into a new era of advertising and first-party data monetization. The integration of e-commerce with advertising presents an exciting opportunity for brands to drive direct sales through ads displayed within retail platforms, blurring the lines between marketing and commerce. Our Consumer View solutions provide access to over 5,000 demographic and behavioral data points, enriching your customer profiles for deeper insights. By combining first-party data with Experian's industry-leading data sets, you can create bespoke audience segments that drive increased return on investment (ROI), going beyond conventional category-based targeting strategies. Looking ahead, the future outlook for RMNs remains promising, with anticipated growth and expansion as brands increasingly recognize the value of reaching consumers precisely at the point of purchase. Connected TV At Cannes Lions 2024, we anticipate discussions to focus on how connected TV (CTV) can continue to live up to its promise. CTV is the most rapidly expanding advertising channel in the U.S and 95% of advertisers plan to increase their share of spend on programmatic CTV in 2024, according to The Trade Desk's latest CTV report. The growing adoption of CTV among viewers, driven by factors like quality content, reduced ad interruptions, and cost-saving alternatives to traditional cable, signals a shift in consumer behavior that marketers cannot afford to overlook. Experian supports the growth of advertising interest in CTV through our signal-agnostic Graph that connects CTV IDs, universal IDs like Unified I.D. 2.0 (UID2), IPs, and mobile ad IDs (MAIDs) for effective activation. Our digital identity resolution with Activity Feed provides insights into CTV viewership behavior, linking CTV exposure to e-commerce conversions. CTV also enables greater collaboration, and we've recently announced new partnerships with CTV industry leaders Microsoft, Samsung, Attain, Sonobi, and EDO. Consumer privacy Consumers are increasingly aware of privacy concerns surrounding their data and numerous laws are going into effect across the U.S. at the state level. Most recently, there has been momentum on a federal data privacy law. We expect consumer privacy to be a significant topic of discussion at Cannes Lions 2024, reflecting the growing importance of ethical data practices in advertising. In a recent Q&A with Datavant, Jeremy Meade, VP of Marketing Data & Product Operations at Experian, highlights the importance of balancing data privacy and utility, focusing on "data for good" practices while using de-identification techniques to support research without compromising consumer privacy. Our Geo-Indexed audiences are an example of how Experian can help you reach your audience while balancing data privacy and accuracy. Our Geo-Indexed audiences combine location data with audience insights to deliver targeted marketing solutions. These audiences are created without the use of sensitive personal information, so you can confidently reach your target audience without sacrificing data privacy. 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. Campaigns and competition The theme of campaigns and competition is poised to be an important discussion point, driven by the convergence of major global events like the U.S. presidential election and this summer’s games—both occurring once every four years. These landmark occasions present opportunities for marketers to craft targeted campaigns that resonate with specific audience segments. As we approach the 2024 election season, the advertising landscape is primed for growth, with political ad spending projected to exceed $10 billion. Effective audience targeting during this crucial period can sway voters, shape public opinion, and influence election outcomes. Experian's 240+ politically relevant syndicated audiences, including our 10 political personas, enable a nuanced understanding of voter viewpoints and empower tailored engagement strategies to connect more effectively with constituents. At the same time, this summer’s games in Paris offer a unique opportunity for sports marketing. With one billion viewers expected to tune in, the global spectacle presents a platform to engage with passionate sports audiences worldwide. Using Experian's syndicated audiences, marketers can precisely target sporting goods shoppers, avid fans, athletes, and spectators alike. The combination of these major events emphasizes the need for careful planning and data-driven strategies and marketers should take advantage of the excitement surrounding both events.
