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!

In this article…Typical paths to programmatic TV ad buying What platforms can your programmatic ads show on?Where to get started with programmatic TV buying How to optimize your bids for smarter ad spend In advertising, it’s crucial to maintain efficiency and cost-effectiveness through every campaign. Whether you’re a seasoned marketer or just starting with programmatic advertising, finding the best deal for programmatic TV ads is essential. In this blog post, you’ll learn about the intricacies of programmatic TV and how you can uncover the best paths, platforms, and strategies to maximize your advertising budget. Typical paths to programmatic TV ad buying Programmatic advertising has revolutionized how businesses reach their target audience on television and has become an increasingly popular marketing approach. So far, in 2023, 87% of connected TV (CTV) ads have been bought using programmatic methods. That percentage is expected to continue rising as more advertisers take advantage of this buying method. To find the best deal for cheap programmatic TV, it’s essential to understand the typical paths to programmatic media buying: direct deals and programmatic auctions. Direct deals One common route for programmatic ad buying is direct deals with publishers and broadcasters. This approach gives you more control over your ad placements, allowing you to negotiate pricing and secure prime time slots. However, this method can be expensive as premium placements often have a premium price tag. Programmatic auctions Another option is programmatic auctions, where advertisers bid on available ad inventory in real time. These auctions can be public or private, each with its own benefits. Public auction Public auctions are the primary marketplace for cheap programmatic TV ad buying, and advertisers compete in real-time for available ad slots. This option can be cost-effective if you are strategic with bidding. However, it can be highly competitive, which could drive up prices. Private auction A private auction provides a more controlled bidding environment. These auctions offer access to premium inventory and the ability to negotiate directly with publishers and broadcasters. Prices are typically higher at private auctions, but they can lead to more exclusive, high-quality ad placements to better reach your target audiences. Auction vs. direct The auction vs. direct debate is crucial for finding the best deal in programmatic TV advertising. Direct programmatic ad buying involves establishing personal relationships with publishers and broadcasters. This approach offers more control over ad placements, creates the potential for long-term partnerships and premium positions, and allows for more negotiation power on pricing. On the other hand, the auction route relies on real-time programmatic auctions that give advertisers more efficiency, dynamic pricing through competitive bidding, and access to diverse ad inventory. This approach also allows better data-driven decision-making to help advertisers with precise targeting and optimization. What platforms can your programmatic ads show on? Programmatic ads are limited to traditional television. You can use various platforms to broaden your audience reach, including blogs, lifestreams, and more. Multiple platform options also let advertisers search around for cheap programmatic ad buys. Some popular platforms include: Display and video YouTube videos Custom publisher formats Audio ads Unexpected platforms where you can buy programmatic TV ads Some unexpected platforms offer unique opportunities to find the best programmatic TV deals. Some of these examples include: YouTube shorts Mobile games Music streaming apps Pinterest TikTok Try local Local (linear) television advertising often flies under the radar, but it can be a goldmine for finding cheap programmatic ad buys. Customize your messages to local audiences by focusing on specific geographic regions. This level of specificity can lead to highly efficient ad campaigns with lower costs compared to national or global placements. Where to get started with programmatic TV buying When it comes to programmatic TV ad buying, you have two main options: using an agency or going directly to the marketplace. Using an agency Advertising agencies have the expertise to navigate the complexities of programmatic TV ad buying. By working with one, you may be able to find better deals and get help negotiating terms and optimizing your campaigns. However, remember that agency fees could take up a large portion of your budget. Going to the marketplace For a more hands-on approach, you can explore programmatic ad buying directly through the marketplace. This approach gives you direct control over your campaigns and the ability to explore different deals and platforms. However, you’ll want to understand programmatic advertising strongly to ensure you make the most of the marketplace. How to optimize your bids for smarter ad spend Finding the best deal doesn’t end with choosing the right options for programmatic buying. You need to focus on smart bidding strategies to optimize your advertising budget. Choose placement based on segmentation Segmentation is vital to maximizing your ad spend. By targeting the specific audience segments most likely to convert, you can make the most of your budget. Platforms often offer options to narrow your audience based on behavior, interests, and demographics. Work with an identity resolution provider Identity resolution is the process of matching online and offline customer data, giving you a comprehensive view of your target audience. By working with an identity resolution provider, you can make informed decisions about where and when to place your programmatic TV ads for the best results. Create an omnichannel view of your campaign To find the best deals on cheap programmatic ads, it’s essential to have an omnichannel view of your advertising campaign. By coordinating your programmatic media with other channels, you can create a seamless and cohesive brand experience for your audience.
