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.

We’re excited to introduce the next segment in our Q&A series, Ask the Expert! Ask the Expert features a series of conversations with product experts where we dive into the areas you care most about like identity resolution, targeting, attribution, and more. Our next segment features a conversation about sell-side targeting. Mike Chowla, SVP of Product at OpenX joins us to chat with Experian’s SVP of Sales & Partnerships, Chris Feo. OpenX is the world's leading sell-side platform for audience, data, and identity targeting. In their conversation, Mike and Chris review: The shift to targeting on the sell-side How first- and third-party data are being used on the sell-side How OpenX is thinking about alternative IDs Watch the recording What is sell-side targeting? Sell-side targeting optimizes the way buyers and supply-side platforms (SSPs) work together. This approach moves the responsibility of inventory and audience targeting from the demand-side platform (DSP) into the SSP, providing advertisers with increased reach and better performance. With sell-side targeting, locating your target audience becomes easier as you have a more direct connection with publishers. This increases your ability to scale against a target audience. Specifically, the SSP directly matches the buyer's audience or data segment to the publisher inventory and audience and automatically sends the impression to the buyer's DSP of choice via a deal ID, providing advertisers with improved reach and performance metrics as well as control over their inventory. With more direct access, your budget can likely go further, and you can decrease your effective cost per mille (eCPM) and get more working media. "Supply-side targeting is the next phase of how supply path optimization (SPO) and buyers will need to work more closely with SSPs." – Mike Chowla, SVP, Product, OpenX Buying on the sell-side vs. open exchange When buying on the open exchange, you have access to a vast number of impressions. With sell-side targeting, you can apply your campaign targeting directly on the supply-side and activate those impressions through a deal ID. Sell-side targeting works across various formats including web display, mobile, in-app, and connected TV (CTV) for a seamless advertising experience. OpenX offers the unique capability to match users using their device graph within their SSP. This means you can target users from traditional data sources such as cookies or mobile ad IDs (MAIDs) and reach them in CTV or app environments. This gives you even more reach and precision in your advertising efforts. The role of first- and third-party data on the sell-side Buyers are showing a keen interest in bringing their own first-party data into the process of sell-side targeting. Meanwhile, certain agencies have been actively involved in working with identity and data. OpenX is currently collaborating with several agency ID solutions such as Choreograph, Merkel, and Horizon. Buyers are also purchasing third-party data and data segments from various providers through OpenX's platform for sell-side targeting purposes. By utilizing this data on the supply side, buyers are able to increase the match rate against their first- and third-party data segments in all environments. This ultimately maximizes scale against these audiences and drives a more efficient CPM due to eliminating waste. Measurement and attribution on the sell-side In the current state of SSP advertising, there is more of an emphasis on targeting capabilities than measurement and attribution. That said, SSPs can provide granular log level reports that can be utilized for multi-touch attribution (MTA) or mixed media models (MMM). These granular insights not only inform measurement and attribution models, but they also provide valuable optimization insights such as clearing price. Additionally, advertisers have all of the same reporting options that they’re used to getting through their DSP because their buys are activated via deal ID in the DSP of their choice. What to consider when transitioning to sell-side targeting There are two primary items you should consider when transitioning to sell-side targeting: Supply Reach Reach Collaborating with partners who have the right capabilities can greatly improve reach and audience extension across different devices. For instance, if you bring your first-party audience or a third-party audience and are identifying that consumer via a cookie or MAID, being able to extend that targeting segment to other devices and platforms can be highly beneficial. Supply It's crucial to collaborate with partners who have the right access to supply and direct connections with publishers. While targeting is essential, it's equally important to have high-quality supply to drive performance. Reaching consumers in a cookieless future Whether you're targeting on the demand or sell-side, it always starts with the consumer and who you're trying to reach. Significant changes in the consumer privacy landscape are impacting advertisers' ability to access various signals emitted by consumers through their devices and browsers. Recent developments from Apple and Google have further amplified this situation. Alternative IDs as a solution to signal loss In response, we're seeing the emergence of alternative IDs like UID2, Ramp ID, and ID5. OpenX supports these types of IDs and considers them crucial for audience buying in a privacy-centric cookie-less future. We are still in the early stages of this evolution. While some of the IDs have good coverage, cookies will continue to be the primary targeting method as long as they remain available. Nevertheless, we see alternative IDs as one of several solutions that will become increasingly important as third-party cookies disappear. Contextual buying will also emerge, and a set of solutions will come together to enable advertisers to keep finding their audience in a cookie-less world. Overcoming signal loss with identity resolution Looking ahead, as we continue to lose signals due to the evolving consumer privacy landscape, we will witness two things: Continued fragmentation A wide variety of identifiers Content will continue to be available on various devices. We're currently experiencing the emergence of connected TV, but who knows what other devices will surface over the next five to ten years. As cookies disappear, which have been the primary identifier, and alternative IDs are introduced, the wide variety of identifiers will create further fragmentation. This highlights the need for identity in the future. Identity resolution at Experian matches fragmented identifiers to a single profile to create a unified, cross-channel view of your consumers. Our identity resolution solutions can help future-proof your marketing strategies. How Experian and OpenX work together Experian is a key player in OpenX's OpenAudience solution and helps to power many of their data segments as well as their identity graph. While OpenX collaborates with a variety of providers and operates a fully interoperable platform, Experian remains valuable to the core technology within OpenX's SSP.

As Earth Day approaches, it’s the perfect opportunity for marketers to explore innovative ways to engage with eco-conscious customers. With a strong and growing interest in sustainable business practices worldwide, green audiences are becoming increasingly influential. In addition to being good for the planet, engaging these customers is great for any brand or organization striving to become more eco-friendly and socially responsible. By taking advantage of this timely event and using appropriate tools, you can create personalized campaigns that will both promote your brand and increase customer loyalty. Eco-conscious audiences In this blog post, we'll cover three eco-conscious audiences to target this Earth Day: Solar energy GreenAwareTM Electric vehicles Solar energy Our first eco-conscious audience is Solar energy. Consumers in this audience show an inclination toward harnessing the power of the sun as a clean, renewable energy source. Our audience data can provide valuable insights into the Solar energy consumer base, including their age, education level, occupation, household income, and communication preferences. Let's explore these metrics to better understand how to reach this group effectively. Age and living situation Consumers in our Solar energy audience are more likely to live in a home with two or more adults and are between the ages of 45-74. Education level and occupation Consumers in our Solar energy audience are more likely to have graduated from college or graduate school and work in management-level occupations. Household income Consumers in our Solar energy audience have household incomes of more than $75,000 and their homes are valued at over $550,000. Preferred engagement channels Consumers in our Solar energy audience are most receptive to ads served through digital channels like digital newspapers and email. Solar energy audience pairings Consumers in our Solar energy audience also belong to three of our Mosaic® USA groups: Power Elite Flourishing Families Booming with Confidence Our consumer segmentation portal of 126 million households and 650 lifestyle and interest attributes empowers marketers like you to precisely target your ideal audience and communicate with them on a personal level. Mosaic’s data segments the U.S. into 19 overarching groups and 71 underlying types, giving you the insights needed to anticipate the behavior, attitudes, and preferences of your most profitable customers and communicate with them on their preferred channels, with messaging that resonates. GreenAware Our second eco-conscious audience is GreenAware. GreenAware segments the 126 million U.S. households within Experian Marketing Data into four distinct groups. Each group differs in their attitudes and behaviors toward purchasing products that are environmentally safe and working with companies that are eco-conscious. We created these groups using an enhanced application of traditional statistical clustering techniques based on environmentally relevant measurements in Simmons' National Consumer Study. Based on the distinctive mindset of consumers toward the environment, you can learn how environmental concerns fit into their lives through four major consumer segments: Eco-Friendly Enthusiasts Sustainable Spectators Passive Greenies Eco Critics Let's dive deeper into each group to understand their unique perspective on the environment and how this impacts their attitudes and behaviors. Eco-Friendly Enthusiasts This eco-conscious segment prioritizes a green lifestyle and takes pride in avoiding products that harm the planet. With traditional and liberal values, they embrace optimism and prioritize family. With their children out of the house, they take the time for some well-deserved rejuvenation and are committed to a healthy lifestyle. Some members of this group are transitioning into retirement and welcoming a new chapter in their life. Mature adults and retirees College graduate or more Above average income May be married or single Typically own their homes Sustainable Spectators This segment aspires to be more sustainable, but they struggle with translating their green ideas into action. They have a soft spot for a cozy home. While their love for interior design and taking care of their own space is evident, they're always looking for new experiences and opportunities to learn. Staying healthy and active is a top priority for this group, so it's no surprise that they're always looking for ways to stay fit and feel their best. Established and mid-life adults College graduate or more High income Typically married Likely to own their homes Passive Greenies This is the largest and one of the most youthful groups. Known for their love of exploration and self-discovery, they may not have fully embraced eco-conscious behaviors yet, but they are eager to stay current with the latest technology and trends. With their incredible ability to multitask, they're always on-the-go, and constantly seek the next best thing. Mainly young adults and diverse Education ranges from high school through some college Below average income More likely to be single or divorced Typically rent Eco Critics This group is not likely to be eco-conscious and may have negative attitudes about the environment. They are confident, driven, and focused on their personal growth. They crave instant gratification, seeking out quick and easy solutions to their everyday decisions. They place a high value on entertainment, their social life, and carefully curate their image. Young and established adults Education ranges from high school through post-graduate studies High income Married or single Typically own their homes Let's take a look at how the GreenAware segments stack up against each other in terms of age, household income, education level, and media preference. How do they compare? Let's find out. Age Consumers in the Eco-Friendly Enthusiasts segment are the oldest of the four GreenAware segments – about half of the consumers are 65 or older. Eco Critics are the youngest segment, with over half of consumers in this group between ages 25-44. Household income Sustainable Spectators and Eco Critics are the wealthiest GreenAware segments. The average household income of consumers in these segments is above $100,000. Passive Greenies have the lowest household income, with a majority below $50,000. Education level and occupation Passive Greenies are more likely to work Blue Collar jobs and have the lowest level of education. As the wealthiest segments, Sustainable Spectators and Eco Critics have the highest levels of college degrees and work in management, business, and financial operations. Eco-Friendly Enthusiasts are the most likely to be retired and out of the workforce. Preferred engagement channels Streaming TV is the preferred engagement channel for all GreenAware segments. Eco-Friendly Enthusiasts prefer digital channels like digital newspapers, mobile SMS, and email. They also engage with traditional channels like direct mail and newspaper. Passive Greenies have a high preference for digital display, mobile SMS, digital video, broadcast cable TV, and radio. Eco Critics have a high preference for digital channels like digital newspapers, mobile SMS, and digital display. Sustainable Spectators strongly prefer digital newspapers. They don't show as strong of a preference for mobile SMS and digital display as Eco Critics and Passive Greenies. GreenAware audience pairings Six of our Mosaic groups have at least one GreenAware segment with 10% or more of the population. For more precise targeting, below are suggested Mosaic audiences you can pair with each GreenAware segment: Eco-Friendly EnthusiastsSustainable SpectatorsPassive GreeniesEco CriticsBooming with ConfidencePower EliteSingles and StartersPower EliteAutumn YearsBooming with ConfidenceGolden Year GuardiansSuburban StyleGolden Year GuardiansSingles and Starters Electric vehicles Our third eco-conscious audience is electric vehicles. Electric vehicles (EVs) are having a major moment in the automotive industry. This is no surprise given that new EV models are being released and an increasing number of charging stations are popping up around the country. As EVs become more prominent, it's essential to stay up to date on relevant trends to make informed decisions about what lies ahead. The demand for electric vehicles (EVs) is on the rise Consumers are embracing the EV revolution, showing their desire for a cleaner, greener future. Automotive marketers are increasingly looking to reach in-market EV shoppers and current alternative fuel vehicle owners due to the growing availability of electric vehicles, improved infrastructure, and rising popularity. In 2022, EVs charged up the market and accounted for a remarkable 6% of new retail registrations. While Tesla continues to dominate the EV market, Ford, Chevrolet, and Hyundai are starting to compete, each holding more than 3% of the market share of new retail EV registrations. Geography Where are we seeing the most new retail EV registrations? The top designated market areas (DMAs) for new retail EV registrations are mostly located in heavily populated, coastal cities like Los Angeles, CA and New York, NY. The fastest growing DMAs, however, are in smaller cities like Tucson, AZ and Oklahoma City, OK. Generational demographics Gen X and Millennials make up the largest percentage of new retail EV buyers at 37.5% and 34.4%. Gen Z and the Silent generation represent the smallest shares at 5% and 2.1%. Boomers hover between Gen X and Millennials' share and account for 20.6% of new EV retail purchases. EV audience pairings Our top five Mosaic groups for new EV buyers include: American Royalty Cosmopolitan Achievers Philanthropic Sophisticates Couples with Clout Fast Track Couples How to target consumers in-market for electric vehicles We offer 70+ audiences that are focused on likely buyers and owners of EV and plug-in hybrid (PHEV) vehicles. We also offer a subset of 28 audiences focused on individual EV/PHEV vehicle models. Below is how you can find a few of these audiences on-the-shelf of most trusted advertising platforms: Autos, Cars, and Trucks > In Market-Fuel Type > Electric Autos, Cars, and Trucks > In Market-Fuel Type > Used Electric Autos, Cars, and Trucks > In-Market Make and Models > Tesla Autos, Cars, and Trucks > In-Market Make and Models > Chevrolet Bolt EV We can help you reach eco-conscious consumers Earth Day is a great opportunity to get creative with your marketing efforts with our three eco-conscious audiences: Solar energy, GreenAware, and electric vehicles.

Advertisers are always looking for ways to improve the targeting and effectiveness of their campaigns. One strategy that's gaining popularity lately is using curated private marketplace (PMP) deals, allowing advertisers to buy premium ad inventory in a private auction environment. But how do data providers and PMPs work together to make PMP advertising more successful? What is a private marketplace (PMP)? Advertising PMPs, or private marketplace deals, are a type of programmatic advertising where advertisers and publishers negotiate and set up a direct deal between themselves to buy or sell advertising inventory in a private auction environment. In PMP deals, publishers can make their premium inventory available to a select group of advertisers, who can bid on it in a private auction using demand-side platforms (DSPs). These private auctions typically offer higher-quality inventory and a more targeted audience than open exchange auctions, which are accessible to all advertisers. However, traditional PMPs had their limitations, including often being limited to accessing inventory from a single publisher group. Audigent takes PMP advertising to the next level with SmartPMPs Audigent's key differentiator is that instead of activating audience data from the DSP, which is the industry standard, they integrate directly with supply-side platforms (SSPs). By taking this route, audience data and inventory from hundreds or even thousands of publishers can now be packaged together into a single deal ID / SmartPMP. SmartPMPs empower media buyers with the ability to access and buy against unique, customizable data segments on premium curated publisher inventory in combinations that otherwise would not have been available. Activating data via the supply-side also enables supply-side optimizations. This means that instead of simply being a data provider, Audigent plays an active role in the success of media buyers' programmatic campaigns by optimizing toward performance goals in coordination with demand-side buyers. The result is the full alignment of demand- and supply-side technologies for the first time in programmatic. SmartPMPs drive campaign performance Audigent performance data compared to the programmatic open exchange: How Experian and Audigent partner in PMP advertising Experian and Audigent collaborate using Consumer View audience data. By supplying valuable insights into users' interests, behaviors, and demographics, we help advertisers create more targeted and personalized ad campaigns with Audigent.
