AdTech can feel overwhelming with all its jargon, but we're breaking it down café-style. From first-party data and identity resolution to clean rooms and ID-free targeting, this guide breaks down the essential terms marketers need to know.In this article…
If you’ve ever sat in a meeting and heard an AdTech term you didn’t understand, you’re not alone. The industry evolves as quickly as a café turns over tables on a busy weekend. Even seasoned regulars can get tripped up by the jargon.
So instead of scratching your head over the “menu,” let’s walk through some of the most common terms: served café-style.
The ingredients: The many flavors of first-party data
Every meal starts with ingredients, and in AdTech, those ingredients are data. First-party data is not just one thing: it’s more like everything your favorite neighborhood café knows about you.

First-party data
The café knows your coffee preferences because you’ve told them directly; whether by ordering at the counter, calling in, or placing an order online. This is information you’ve willingly provided through your interactions, and it belongs only to that café.
First-party cookies
The barista writes down your preferences in a notebook behind the counter, so next time you walk in, they don’t have to ask. First-party cookies remember details to make your experience smoother, but only for that café.
Authenticated identity
A loyalty app that connects online orders to in-person visits. By logging in, you’re saying, “Yes, it’s really me.” Authenticated identity is proof that the customer isn’t just a face in line, but someone with a verified profile.
Persistent identity
Recognizing you whether you order through the app or in person. Persistent identity enables the ability to keep track of someone across different touchpoints, consistently, without confusing them with someone else.
Permissioned data
Agreeing to join the loyalty program and get emails. Permissioned data is a connection to the customer that the customer proactively shared with the café by signing up for their loyalty program or email newsletter.
Each piece comes from direct interactions, stored and used in different ways. That’s what makes first-party data nuanced. The saga of third-party cookie deprecation and changing privacy regulations makes it important to understand which types of data you can collect and use for marketing purposes.
And once you have those ingredients, the next step is making sure you recognize how they fit together, so you can see each customer clearly. That’s where identity resolution comes in.
The recipe: Bringing the ingredients together with identity resolution
At the café, identity resolution is what helps the staff recognize you as the same customer across every interaction. Without it, they might think you’re two different people; one who always orders breakfast and another who sometimes picks up pastries to go.
Matching
The café has a loyalty program, and the pet bakery next door has one too. When they match records across their two data sets, they realize “M. Jones” from the café is the same person as “Michelle Jones” from the bakery. That connection means they can activate a joint promotion, like free coffee with a dog treat, without either business handing over their full customer lists. In marketing, matching works the same way, linking records across data sets for activation so campaigns reach the right people.

Deduplication
Collapses duplicate profiles into a single, clean record, so you don’t get two birthday coupons, even though that would be nice to get.
That’s what Experian does at scale: we connect billions of IDs in a privacy-safe way, so you can get an accurate picture of your audience.
And once you can recognize your customers across touchpoints, the next challenge is collaborating across systems and partners for deeper insights. That’s where the behind-the-counter processes come in.
Behind the counter: Crosswalks and clean rooms
At a café, these terms are like the behind-the-counter processes that keep everything running smoothly. They may sound technical, but they all serve the same purpose: helping data collaborate across different sources, while keeping sensitive information safe. The goal is a better “meal” for the customer, deeper insights, better targeting, and more personalized campaigns. Here’s how they work.
Crosswalks
The café partners with the pet bakery next door. They both serve a lot of the same people, but they track them differently. With a crosswalk, they can use a shared key to recognize the same customer across both businesses, so you get a coffee refill, and your dog gets a treat, without either one handing over their full customer list. A crosswalk is the shared system that lets both know it is really you, without swapping personal details. It’s the bridge connecting two silos of data.

Clean rooms
The café and the pet bakery want to learn more about their shared customers, like whether dog owners are more likely to stop by for brunch on weekends. Instead of swapping their full records, they bring their data into another café’s private back room, a clean room, where they can compare trends safely and privately. Both get useful insights, while customer details stay protected. That’s a clean room: secure collaboration without exposing sensitive data.
Of course, sharing and protecting data is only part of the picture. The real test comes when you need to serve customers in new ways, especially as the industry moves beyond cookies.
Serving customers in new ways: Cookie-free to ID-free
Targeting has evolved beyond cookies, just like cafés no longer rely only on notebooks to remember regulars.
ID-free targeting
The café looks at ordering patterns, like cappuccinos selling on Mondays and croissants on Fridays, without tracking who’s ordering what. Instead of focusing on who the customer is, the café tailors choices based on the context of the situation, like time of day or day of the week. This is like contextual targeting, serving ads based on the environment or behavior in the moment, rather than on personal identity.

ID-agnostic targeting
The café realizes customers show up in all sorts of ways: walk in, online ordering, delivery. Each channel has its own “ID,” a name on the app, a credit card, or a loyalty profile. ID-agnostic targeting means no matter how you order, the café can still serve you without being locked into one system.
Just like cafés no longer rely only on notebooks to keep track of regulars, marketers no longer have to depend solely on cookies. Today, there are multiple paths, cookie-free, ID-free, and ID-agnostic, that can all help deliver better, more relevant experiences.
But even with new ways to reach people, one big question remains: how do you know if it’s actually working? That’s where measurement and outcomes come into play.
Counting tables vs. counting sales
At the café, measurement and outcomes aren’t the same.
Measurement
Tables filled, cups poured, specials ordered.
Outcomes
What it all means: higher revenue, more loyalty sign-ups, or increased sales from a new promotion.

Both matter. Measurement shows whether the café is running smoothly, but outcomes prove whether the promotions and strategies are truly paying off. Together, they help connect day-to-day activity to long-term success.
All of this brings us back to the bigger picture: understanding the menu well enough to enjoy the meal.
From menu to meal
In AdTech, there will always be new terms coming onto the menu. What matters most is understanding them well enough to know how they help you reach your business goals. Just like at the café, asking a question about the specials isn’t foolish. It’s how you make sure you get exactly what you want. The more we, as an industry, understand the “ingredients” of data and identity, the better we can cook up new solutions that serve both brands and consumers. After all, the goal isn’t just to talk about the menu, it’s to enjoy the meal.
At Experian, we help brands turn that menu into action. From identity resolution to privacy-safe data collaboration, our solutions make it easier to connect with audiences, activate campaigns, and measure real outcomes.

FAQs
First-party data is information a customer shares directly with a brand, like purchase history, preferences, or sign-ups. It’s the most valuable and privacy-safe data marketers can use to build personalized campaigns.
Identity resolution ensures a brand can recognize the same customer across different touchpoints. Matching links records across data sets (e.g., between partners) so campaigns reach the right people without exposing full customer lists.
A crosswalk bridges two data systems with a shared key to recognize the same customer, while a clean room allows partners to analyze data together securely without exposing sensitive details.
Cookie-free and ID-free targeting shift focus away from tracking individuals, instead tailoring ads based on context (like time of day or content being viewed) or allowing flexibility across multiple IDs.
Measurement tracks activity (like clicks or visits), while outcomes prove business impact (like sales, loyalty, or revenue). Both are essential, but outcomes show whether strategies are truly effective.
Experian provides tools for identity resolution, privacy-safe data collaboration, and campaign measurement, helping marketers move from understanding the “menu” of AdTech terms to achieving real results.

The UK digital advertising market is worth £13.44bn, an increase year-on-year of 15%, reveals the 2018 IAB UK & PwC Digital Adspend Study. Report highlights The majority of all growth is coming from smartphone advertising, which has increased by £1.65bn (35%) from 2017. Smartphone advertising now represents 51% of all UK digital ad spend, up from 45% in 2017. Video is now the largest display format (£2307m), overtaking standard display banners (£1486m). Outstream/social in-feed has increased its majority in total video spend, now occupying a share of 57%, up from 52% in 2017. Social revenue now represents 23% of all digital ad spend. Growth is predicted to slow during 2019, with 5% estimated growth (+9% digital, +11% display, +9% search) compared to 15% in 2018. 2018 marks the tipping point towards a mobile-first ecosystem “For the past few years, industry commentators have been hailing the year of mobile. Each January the predictions come and the waiting commences for evidence to mark a tipping point, a shift to a mobile-first digital ad ecosystem. Well, drumroll… it was 2018! The latest Adspend report from IAB UK and PwC reveals that spend on smartphones outstripped spend on desktop for the first time last year. Brands spent 51% of total spend (which stands at £13.44 billion) on smartphones in 2018, up from 45% in 2017 – a significant milestone in the evolution of digital advertising. “This evidence shows that advertisers are increasingly thinking mobile-first. Growth in investment has historically lagged behind the amount of time spent on the device and we expect to see growth continue at a rapid pace to keep up with audience behaviour – two thirds of time spent online is now on mobile, according to UKOM. Other areas of growth highlighted by the report include video, which accounts for 44% of the total display market, while mobile video now makes up 51% of smartphone display. This is no doubt down to bigger mobile screens, better 4G and more readily available WiFi making video ads an increasingly attractive option. “Across the board, advertisers are investing in digital for longer-term brand building as well as short-term activation, with the direct-to-consumer market helping to drive this trend. What’s more, digital continues to be an accessible and popular route to market for businesses of all sizes, from leading advertisers to SMEs.” Tim Elkington, Chief Digital Officer, IAB UK Content & context crucial for attracting audiences “As people spend more and more of their time on mobile, it’s comes as no surprise that advertisers will follow where audiences are with their marketing spend. “Video has been the driving force in this growth, indicating that engaging visual content is still key in helping brands to achieve great results and to capture consumer attention in a vast sea of digital noise. “Video still has a way to go if it is to reach the level of effectiveness of traditional formats like cinema, but it will be interesting to see how the format develops over the next year or so. Ultimately, brilliant content and properly considered context are crucial for advertisers hoping to attract relevant audiences and build strong brands long term.” Kathryn Jacob OBE, CEO, Pearl & Dean Mobile-first approach driving investment in user experience “As a mobile-first approach has become the norm for many businesses, we’ve seen significant innovation and investment in the user experience that has fuelled the rise in mobile commerce. “Yet, for some years, limitations in the technology and formats available have meant that mobile advertising couldn’t always keep pace with changing consumer behaviours – delivering weaker performance when compared to desktop. “Fortunately, mobile has made huge strides in recent years. Mobile advertising affords great targeting opportunities for brands and a more interactive and immersive experience for consumers. “There is no reason to doubt this trend will continue as advertisers design their media, creative, and targeting strategy with mobile at the heart – optimising performance, enhancing the customer experience, and delivering the best results.” James Cragg, UK Managing Director, Tug New technologies to improve investment efficiency “The UK digital ad market has continued to grow despite the various challenges that the market has faced, including the current socioeconomic climate and general changes in the industry. As spend increases, it’s important to look at how media buying can be made as efficient as possible, minimising waste and maximising the return on investment. “Marketers will start to look to new technologies, like AI, to offer an impartial and more efficient approach to media buying, allowing marketers to measure effectiveness of campaigns and allocate spend accordingly.” Carl Erik Kjaersgaard, Chief Executive, Blackwood Seven Industry going from strength to strength “This significant growth in ad spend is great to see and shows that our industry is going from strength to strength. It’s especially good to see that as advertisers invest more and more in digital advertising, they’re becoming more considered in where they’re spending their money – with a large portion of the growth coming from companies that are part of IAB’s Gold Standard. “At The Trade Desk, we’ve long been ambassadors for the importance of transparency. These findings show that it isn’t just the right thing to do, but makes good business sense as advertisers increasingly choose partners who are demonstrating a commitment to best practice.” Anna Forbes, UK General Manager, The Trade Desk Advertisers embracing mobile “As consumers spend more of their time online, it’s no surprise that digital ad spend has continued its rise, up 15% to £13.4bn. With digital, in every sense, becoming further embedded in our daily lives, it is inevitable that this number is set to rise further next year. “Given the vast majority of people using their smartphone as their primary digital device, evident from site traffic stats we see across the board, the IAB report shows that advertisers have started to fully embrace this shift by following with ad spend. Over the last few years, a combination of faster wireless connectivity along with more capable devices has made it the go-to device for consumers to get online. This is set to continue over the next few years with 5G and even faster, more capable smartphones arriving (i.e. foldables) that will further cement ‘mobile’ as the main digital device to reach consumers.” Wajid Ali, Head of Paid Search, ForwardPMX Budgets must go to professionally produced content “In the IAB’s latest ‘Digital Adspend Study’ it is positive to see that outstream continues to dominate video spend, showing close to a 10% year-on-year increase. “Unsurprisingly, the study highlights that mobile is the most important distribution device (76% of all video spend is on the smartphone), and it’s great to see the format we invented dominating that space. “However, it’s now more pertinent than ever that clients and agencies invest their outstream budgets into professionally produced content and not social infeeds. Budgets must go where content is being produced, rather than aggregators and distributors, where the content is read rather than where a click happened. “We must remember how important local, national, and vertical press are to the global digital ecosystem. By unifying the best publishers at scale, delivering mobile-optimised creativity and outcome-orientated distribution, we are fighting to ensure publishers are getting their fair share of revenue in comparison to the social platforms.” Justin Taylor, UK MD, Teads UK market in robust health “The latest IAB digital ad spend report shows encouraging signs that the UK digital advertising market is in robust health, with mobile advertising continuing its upward trend. “The rise of up-and-coming ad formats like Shopping Ads, Google’s Responsive Search Ads, and Facebook Messenger Ads show that advertisers are looking for ways to capture consumer attention in the evolving digital landscape. As a result, the lines across search, social, and e-commerce are more blurred than ever with the introduction of features like Checkout for Instagram and Shopping ads on Google Images. Furthermore, with the rapid growth of Amazon’s ads business, e-commerce has quickly emerged as a third pillar of digital advertising, making it vital for marketers to have a complete view of the customer journey across channels and devices, if they hope to more accurately understand campaign performance and attribution.” Wesley MacLaggan, SVP of Marketing, Marin Software Digital identity resolution essential in understanding customer journey “Last year’s figures show that UK ad spend is starting to mirror the behaviour of consumers who, according to UKOM data, spend two-thirds of their time online on a smartphone. The fact that mobile ad spend now surpasses that of ad spend on desktop highlights marketers’ understanding that digital identity resolution is essential, not a nice-to-have. “Appreciating the cross-device behaviours of consumers allows brands to gain a better understanding of the customer journey and build stronger relationships with their audiences long term.” Tom Rolph, VP EMEA, Tapad, a part of Experian.

OpenAudience promises the targeting capabilities of a walled garden but without the restrictionsOpenX has lifted the lid on a targeting solution it claims will offer people-based advertising opportunities outside of the industry’s walled gardens such as Facebook and Google. Dubbed OpenAudience, the supply-side programmatic player claims the new offering is powered by proprietary data assets and is supplemented by data partnerships with partners such as LiveRamp and Tapad, a part of Experian. Initially available in the U.S., OpenAudience has a user graph of 240 million monthly users and is currently being tested with multiple marketers with a general rollout planned for the third quarter of 2019. Speaking with Adweek, OpenX CEO Tim Cadogan said the rollout would help differentiate it among its peers as for the most part ad exchanges have marketed themselves based on their impression count, not necessarily addressable audiences. Compare this with Google and Facebook, both of whom account for almost 60% of U.S. ad spend, although this is disproportionate to the amount of time spent with their properties, according to Cadogan. “The thing that has given Facebook and Google so much power is that they have people-based systems [for ad targeting] that are simple to use and operate with a massive scale that are effective, and programmatic hasn’t kept pace with that,” he said. Cadogan cited the findings of a further study by eMarketer, which indicated that marketers are increasingly reliant on such walled garden players for their online inventory supply with the latest launch geared towards capitalizing on that. The latest launch is the culmination of the California-based company’s recent strategic overhaul, namely its attempts to get to grips with an identity-based solution that provides options outside of the walled gardens. Also speaking with Adweek was Todd Parsons, OpenX’s chief product officer, who offered further insight into how OpenAudience operates including how it uses its recently sealed relationship with Google Cloud Platform and machine learning to ape the efficacy of walled garden advertising solutions. “We had to build a matching technology, which made it possible for us to talk about monthly active users instead of talking about cookies or devices,” he explained. “And it took several quarters of staffing up with the right people from the consumer data and identity space.” OpenAudience’s matching technology works by using the identity and cookie matching capabilities of cross-device specialist Tapad and data onboarder LiveRamp to formulate a persistent, deterministic ID which can then be used to match advertisers with audiences on its ad exchange. “So, the idea isn’t for us as a company to put our future into one provider,” added Parsons. “It is to provide a matching technology that uses the best of several.” OpenAudience will also include involve additional tie-ups to offering further demographic information on the 240 million monthly U.S. users such as location, etc., which is currently in testing. “We felt like we needed to be very different about enabling marketers and publishers to activate against that data,” added Parsons. He further added that OpenX wants to rival Facebook’s levels of service when it comes to helping publishers monetize audiences on the social network, except this time on the open web. “No one has actually pushed identity and consumer data into the hands of publishers in a way that you might unify the view of audiences across many websites.” OpenX’s Cadogan summed up the OpenAudience offering and how it may look to advertisers when he said, “Imagine the open web is one publisher, and this lets buyers look at it as a single entity and market to them accordingly.” Contact us today
