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!

Globalization affects retailers in a number of ways. Complying with commercial laws wherever they have brick-and-mortar stores is one such impact. Navigating through privacy rules that impact e-commerce efforts is another. There is one blind spot in particular that deserves attention — sending shopping cart abandonment emails. I am often asked, “How are abandonment emails treated under the CAN-SPAM Act? Canada’s stringent Anti-Spam Law (CASL)?” “Can I even send abandonment emails to my Canadian customers?” What are cart abandonment emails? But let’s back up… What is an ‘abandonment’ email anyway? In the email space shopping cart abandonment refers to a particular type of automated mailing used to re-engage an online customer. The most common example is one where a retailer notices that a customer has left an item sitting in their shopping cart, and proceeds to send a reminder with a coupon to complete the order. To fully understand privacy compliance pitfalls with this technique, in the U.S. and beyond, we need to unpack what happens before the abandonment email is sent. Email marketing shopping cart abandonment compliance Abandonment messages are almost always ‘commercial’, particularly if they incentivize a shopper to complete their purchase. In compliance parlance, we call this encouraging the continuation of a commercial activity. In contrast, an order confirmation typically provides factual information about a commercial activity. Under most anti-spam laws, particularly under CASL, marketers need to ensure abandonment messages are not unsolicited. Triggering should account for: Appropriate consent covering email marketing to new or ongoing online relationships. Scrubbing the customer’s email address against your unsubscribe/suppression lists before sending a solicitous message. (This is true under any anti-spam law.) For more information about CASL-compliant consent record keeping and related best practices, you can navigate to the Canadian Radio-television and Telecommunications Commission. Maintaining compliance with online tracking Abandonment emails rely on online retailers tracking their customers’ activity on their websites and tying online behavior back to the email addresses using the same behavioral targeting technologies as those used to deliver Interest Based Ads. This jump across engagement channels to remarket to customers can raise privacy concerns, so online retailers need to pay attention to their privacy compliance obligations. Cross-channel marketing privacy protections Guidance covering privacy policies and practices issued by the Federal Trade Commission are informative and I encourage you to review these with your law department. If you operate outside the U.S., privacy protection laws like Canada’s Personal Information Protection and Electronic Documents Act (PIPEDA) may set out additional obligations with your cross-channel marketing efforts. PIPEDA’s definition of commercial activity, which includes remarketing Privacy Commissioner’s findings under PIPEDA in relation to remarketing Privacy Commissioner’s guidance on online behavioral advertising, the technology of which informs triggered emails Under PIPEDA and similar international privacy regimes, cross-channel marketers will need to (i) clearly and conspicuous inform website visitors that their online activities may result in personalized marketing, (ii) offer a way to opt-out of such tracking, and (iii) obtain individuals’ prior express consent with tracking involving sensitive personal information such as health data How to manage cross-channel marketing compliance risks As privacy protection regimes around the world continue to mature and absorb rules covering marketing, online retailers need to start adding new vocabulary to their privacy compliance lexicon. For example, shopping cart abandonment efforts produce ‘cross-channel re-marketing campaigns triggered by an identifiable individual’s online behavior.’ While this is a mouthful to say, viewing your engagement efforts through this lens will help you manage compliance risks.
