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!

Marketers are always looking for creative ways to get the most out of their digital marketing investments. While there may be different paths to optimization, reducing media spend and cutting costs without sacrificing ROI is ideal. We empower marketers to take back control of their budgets and reinvent their media strategies by leveraging the right data at the right time. And, given today’s challenging climate, there’s no better time. Every Business Has Different Deeds Whether you’re a direct-to-consumer brand building a loyal customer base or a financial service simply letting customers know you’re here for them during a challenging time– identity resolution is essential to connecting with your audience without breaking the bank. That’s why we have built solutions that provide flexibility and control when you need it most. Putting Data Into Action Experian's "Tapad Graph" is a global, privacy-safe cross device graph is one powerful file. Updated weekly, and containing customized device IDs and digital attributes, The Tapad Graph enables smarter targeting strategies and a reduction of wasted impressions. What that means is more marketing efficiency and a stronger ROI for your business. Saving resources and money sound good to you? This guide breaks down four ways you can implement cost savings measures without sacrificing performance or prohibiting KPIs. Frequency Capping and Suppression Clustering device IDs by the individual and household means you have access to more ways to reach consumers, but it doesn’t always mean you should be using all of them across every campaign. Hone in on the channels and devices where consumers make most of their lower funnel decisions and purchases – and cap brand-awareness level placements or aspirational media that requires more exposure to generate engagement. This doesn’t mean limiting the devices you target, but being more aware of how often you’re targeting the same person across those devices. If you’ve successfully begun, or heck, even completed the consumer journey with an individual, congratulations. Now, you may want to consider what to do with the rest of the digital devices and users in that same household. Sure, there’s a time for conquesting an entire home of purchasers, but that’s not always the most effective way to maximize your media. That’s why The Tapad Graph is built to be flexible, providing a holistic view of all individuals and their associated devices and digital IDs – so you can suppress them once you’ve conquested the household decision maker or achieved the desired lower funnel activity. Save those impressions for someone else and save money for yourself. The great thing is whether you’re uploading this data into a DMP or a DSP, you can segment your target audience with a frequency cap threshold or suppress them entirely. Not only can you apply these tactics across traditional digital media, but we can include Connected TVs for OTT targeting as well, making your media strategy as holistic as your identity resolution tactics. Cross-Device Targeting and Attribution Consumer behavior and device trends are changing these days, so shouldn’t your digital marketing change too? Desktop usage is now up as much as 22%* as more people are working and learning from home. And remember that old iPad? With more people at home, we’re dusting off more devices and tablet activity is increasing more than 30%*. Sure, people are still constantly on mobile– but it might be time to consider implementing cross-device targeting and optimization for those dayparts when their focus is elsewhere. Identity resolution should be a key element of customer journey mapping and attribution in order to truly give credit to the right channels and build a baseline for the right cost-per modelling. Coupling The Tapad Graph with raw events data can granularly attribute engagement, actions and conversions at the digital ID, device, and even user-level – thereby teaching you more about your customer’s preferences. Leverage these insights to create more tailored messaging and promotions on your owned and operated channels, to funnel impressions to specific screens and platforms, and to target users based on where they are in the purchase funnel. Data That Gives You Control If you’re already implementing cross-device, have you started suppressing the devices where engagement with your brand isn’t happening? That’s right, you can use The Tapad Graph after-the-fact as well. Weekly graph updates with 60-day look-backs enable weekly campaign optimizations. That gives you the flexibility and control to avoid devices and platforms where users aren’t as active. You can only make decisions based on the data you have in front of you, so make sure you're partnering with the right solutions for your business.
