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!

Everyone knows that it’s important for businesses to have a clearly defined brand. In the modern world, the personal brand has become just as important, and many professionals are trying to build up their public reputation, expertise and industry authority. In the digital age, there are many different methods and channels you can use to build your personal brand, but some are more efficient than others. According to Forbes Agency Council, here are some of the most effective ways to develop an authentic personal brand.1. Give More Than You Receive Whatever you do, always aim at giving more than you receive. When you build your network, try to bring value to each new person that you meet. When you get featured in some media, see what you can do for them in return. This is the best strategy because actions speak louder than words. People will remember you for what you are, not what your website is. - Solomon Thimothy, OneIMS 2. Define What You Stand For, Then Align Your Actions Define your mission. What is your purpose? What do you want to accomplish, and what is your key message? Once you have answers to those questions, use that mission as a guiding North Star to consistently reinforce your personal brand every day. This will come across in how you lead, how you interact with employees and peers, how you communicate, and how you give back to the community. - Preethy Vaidyanathan, Tapad 3. Develop A Creative Positioning Statement It’s all about positioning your company. You need to have creative positioning statements about who you are and what your company is doing to benefit its clients. Clients want resolutions to their problems, and that’s where you come to the rescue. It’s either sold or ignored. - Cagan Sean Yuksel, GRAFX CO. 4. Speak At An Event Becoming a keynote speaker gives you access to the things you need to elevate your brand: influencer status, large audiences and media profile. But access doesn’t equal attention. While speaking gives you the platform, you need to have something compelling to say. You’ll need a differentiated message, unique presentation style and a great agent to make this strategy successful. - Andrew Au, Intercept Group 5. Focus On A Specific Audience The most effective way to build your personal brand is to create content specifically for a very specific group of people. Create relevant content that details solutions to the unique needs of this audience so that it spreads quickly due to its hyper-relevance. This creates authority and credibility for your personal brand and helps you stand out as being the most relevant expert in your field. - Adam Guild, Placepull 6. Be Ruthlessly Consistent Developing a personal brand requires ruthless consistency in your subject matter and how you present yourself to the world. I go back to the early days of marketing blogs. In those days, some bloggers were all over the map with content. The ones who were consistent with their audience and their goals are the ones who had staying power. They became the authors, speakers and consultants. - Scott Baradell, Idea Grove 7. Follow Through Just like a traditional brand, the quality of your offering helps to build your brand. If you are clear on what you can and cannot deliver and always follow through on your word, your personal brand reputation will precede you and will be lifted by the recommendations of others. - Kieley Taylor, GroupM 8. Build A Solid Reputation “Personal brand” is just a new-age name for reputation. Doing your job exceptionally well, going above and beyond, treating people with respect and kindness, having a point of view—essentially any action that builds a solid professional reputation does the very same for your personal brand. - Jess Cook, TMV Group 9. Define Your Voice Establish your unique voice and personal point of view and stick to it in all you do and all you say. Personal brands must be consistent and have consistency in messaging, attitude and behavior. Express your personal brand through comments on articles, at significant events and important platforms where it can best showcase and support your personal point of view and brand persona. - Pat Fiore, FIORE 10. Create And Share Video Content Video is hard for many people. That’s why it can be your competitive advantage if you do it. Video allows you to be seen, heard and felt emotionally in a way that no other medium can. You may say, “That’s not for me” and that’s fine, but good luck competing with those who embrace it. Barriers to video are so low that building a personal brand without it seems as if you are hiding something. - A. Lee Judge, Content Monsta 11. Share Your Point of View In Everything You Do There are a finite number of topics that make for interesting discussion in our industry, so having a point of view and sharing it through crafted content is vital for building your personal brand. You don’t have to be controversial, necessarily, but considering themes and topics and providing honest commentary that demonstrates experience is the quickest way to build your reputation. - David Harrison, EVINS 12. Stay True To You The most effective way to build your personal brand is to be true to who you are. If you are wildly creative and outgoing, show that in your branding! Don’t hold back in your content; post that crazy Instagram picture that shows the world how you think. If you are conservative, then own that. This passion for who you really are—and what your company really is—authentically shines through. - Katy Boos, Remix Marketing Inc. Contact us today

OpenAudience™ will provide marketers the ability to easily plan and buy advertising for every digitally addressable consumer across the open web LOS ANGELES, May 2, 2019 /PRNewswire/ — For the past decade, the most effective way to advertise in digital media has been on Facebook and Google. Marketers in the U.S. now spend two-thirds of all digital ad spend on the "walled gardens", despite the fact that they receive less than 36 percent of total consumer time spent online. According to eMarketer, addressing this massive asymmetry in advertising – where tens of billions of dollars are over allocated to the walled gardens – is the top concern of marketers in 2019. While programmatic technology has become the primary monetization system for the open web, it has lacked the simplicity and efficacy of walled gardens. Today, OpenX is changing that paradigm by bringing true people-based marketing to the open web for the first time with the introduction of OpenAudience. OpenAudience will provide marketers and publishers with an unprecedented, unified level of knowledge about consumer audiences – through a platform built on privacy by design principles that brings the efficiency and efficacy of walled garden advertising to the open web. OpenAudience is powered by a comprehensive proprietary data asset and supplemented by integrated partnerships with recognized leaders in data and identity like LiveRamp, Tapad, a part of Experian, and more. For marketers, OpenAudience will provide the ability to plan and buy people-based marketing campaigns that combine the impact and ease of use of Facebook advertising with the scale of the open web. OpenAudience is currently in active partner testing with multiple marketers in the U.S., including Fortune 500 financial service and consumer personal care companies, along with one of America's largest online entertainment outlets, and will be generally available to the broader market in Q3 of 2019. For publishers, OpenAudience will deliver user-based knowledge that empowers them to value and sell advertising with unparalleled precision. With the ability to automatically place consumers into high-value audience segments drawn from the more than 240M U.S. Monthly Active Users OpenX reaches across the open web, OpenAudience allows publishers to maximize revenue like never before. "OpenAudience is a natural evolution of programmatic advertising, combining the unified knowledge of people-based audiences with the transactional power of programmatic to create a planning, buying and advertising experience that is unlike anything else in the market today," said Todd Parsons, chief product officer at OpenX. "No exchange in the market today has enabled a unified view of publisher audiences," said Travis Clinger, vice president of strategic initiatives, LiveRamp. "Now, OpenX is democratizing identity across all publishers on the open web, helping marketers to plan and buy audiences the way they do inside walled gardens. We are thrilled to be a key component of OpenAudience." "OpenAudience is an ambitious move into people-based marketing, offering marketers an unprecedented walled garden-like experience on the open web," said Chris Feo, senior vice president of global data licensing and strategic partnerships at Tapad. "As a fellow pioneer in the industry, Tapad is proud that OpenX chose to leverage The Tapad Graph™ to allow marketers and publishers in North America access to our leading digital identity resolution insights across devices."

Tom Rolph, VP EMEA at Tapad, part of Experian, says that ad-sponsored streaming services can be successful if they can deliver a higher quality viewer experience than other streaming services. Last week, Hulu, the streaming service acquired by Fox and now owned 60 per cent by Disney, announced it will be regularising its ad loads. The streaming service will be bringing ad breaks down to 90 seconds in an effort to deliver a better viewer experience. This is a positive move from Hulu and one which other ad-supported streaming services should follow in order to be successful in a competitive market. Previously ad breaks on Hulu could vary wildly, from 180 seconds to 240 seconds, due to existing deals with its three owners: Disney, Comcast and AT&T. Over in the UK, we haven’t suffered from quite as inconsistent an approach as in the US, but there is still viewer frustration with the ad experience on ITV Hub and All4, where the problem tends to be over exposure of the same ad. Therefore, this move to standardise ad break lengths for streaming platforms is one that should be embraced on both sides of the pond. An important shift in this space will be to limit the number of ads during each show, but have better ad targeting to minimise repetitive advertising and increase the ROI of ad spend. All of which can be accomplished by investing in identity resolution products that can support CTV devices. Last year Ofcom found that in the UK subscriptions to Netflix, Amazon and NOW TV have risen above those to traditional pay TV services. With Netflix and Amazon both ad-free and NOW TV only a limited ad funded model, it’s clear that there is a growing appetite for ad-free viewing models. A fact that is only further supported when you consider the role of the BBC and BBC iPlayer. But the picture isn’t entirely negative for ad-funded models. There is demand for great content on ad-funded services in the UK, with ITV Hub boasting over 1bn requests and 540m hours of TV watched. The ITV Hub mobile app has also been downloaded on over 27m devices across the country – with over 22m people now registered to ITV Hub database, including more than half of Britain’s 16-24 year olds. However, to continue to attract and retain younger viewers, the experience will have to improve. There are several areas where ad-supported streaming providers need to improve in order to remain top players in this space: Ad experienceAs explored above, both volume and repetition of ads can be a turn off for viewers, but with Brits already spending a total of £303.16m every month on TV streaming services, according to Finder.com, there is potential for free, ad-funded models to flourish as people hit a limit on what they are willing to spend. There are already signs of improvement with the ad experience, with ITV just signing a deal with Amobee to allow for addressable ads on ITV Hub, while Sky’s AdSmart technology remains best in class and has now crossed over the pond to be used by Comcast stablemate NBC. Server reliabilityA cursory search finds little evidence of ongoing reliability problems with Netflix, but much evidence of problems with ITV Hub and All4, which are both prone to crashing. To compete with bigger players with massive server farms, server capacity needs to be tackled. This is especially true when it comes to live events, where many people will recall ITV Hub’s famous fails during the World Cup. While even some of the larger players have had similar streaming issues (for example, Amazon’s move into live sports streaming when they had to pull UK streaming of the US Open Tennis due to user complaints), viewing experience should be prioritised as the space gets increasingly competitive. Getting the content rightAmazon and Netflix have huge content budgets, but UK broadcasters remain strong in this regard, Channel 4 has enjoyed viewing figures of 7.5m for the Great British Bake Off, while ITV pulled in 13.7m for I’m A Celebrity. By building on UK-specific content that speaks to UK audiences, ad-supported streaming services can continue to pull in more viewers. Mobile accessMore and more Brits are choosing to watch TV content on their smartphone or tablet, according to UKOM-approved comScore data. In fact, 6.5m adults visited the BBC iPlayer app to watch video on either a smartphone or tablet, edging out Netflix which attracted 5.8m Getting the experience right on mobile, with the option to download content so it can be viewed in areas of low or no signal, is key.If UK ad-supported TV stations can crack these key areas for their Connected TV offering then they will be set up to succeed and offer a true home-grown alternative to the US streaming giants.
