The future of identity in cookieless advertising

Published: August 15, 2023 by Hayley Schneider, Content Marketing Manager

The next era of identity is here

The cookieless future is here, and it’s time to start thinking about how you will adapt your strategies to this new reality. In a cookieless world, you will need to find new ways to identify and track users across devices. This will require reliance on first-party data, contextual advertising, and alternative identifiers that respect user privacy.

To shed light on this topic, we hosted a panel discussion at Cannes, featuring industry leaders from Cint, Direct Digital Holdings, the IAB, MiQ, Tatari, and Experian.

Watch the recording of our Cannes panel, "What does the future of identity hold?"

In this blog post, we’ll explore the future of identity in cookieless advertising. We’ll discuss the challenges and opportunities that this new era presents, and we’ll offer our tips for how to stay ahead of the curve.

How cookieless advertising is evolving

Programmatic advertising is experiencing multiple changes. Let’s dive into three key things you should know.

Cookie deprecation

One significant change is cookie deprecation, which has implications for tracking and targeting. Additionally, understanding the concept of Return on Advertising Spend (ROAS) is becoming increasingly crucial.

The demand and supply-side are coming closer together

Demand-side platforms (DSPs) and supply-side platforms (SSPs) have traditionally been seen as two separate entities. DSPs are used by advertisers to buy ad space, while SSPs are used by publishers to sell ad space. However, in recent years, there has been a trend toward the two sides coming closer together.

This is due to three key factors:

The rise of header bidding

Header bidding is a process where publishers sell their ad space to multiple buyers in a single auction. This allows publishers to get the best possible price for their ad space, and it also allows advertisers to target their ads more effectively.

Cookie deprecation

As third-party cookies are phased out, advertisers need to find new ways to track users, and they are turning to SSPs for help. SSPs can provide advertisers with data about users, such as their demographics and interests. This data can be used to target ads more effectively.

The increasing importance of data

Advertisers are increasingly looking for ways to target their ads more effectively, and they need data to do this. SSPs have access to a wealth of user data, and they’re willing to share this data with advertisers. This is helping to bridge the gap between the two sides.

The trend toward the demand-side and supply-side coming closer together is good news for advertisers and publishers. It means that they can work together to deliver more relevant ads to their users.

Measuring and tracking diverse types of media

The media measurement landscape is rapidly evolving to accommodate new types of media, such as digital out-of-home (DOOH). With ad inventory expanding comes the challenge of establishing identities and connecting them with what advertisers and agencies want to track.

Measurement providers are now being asked to accurately capture instances when individuals are exposed to advertisements at a bus stop in New York City, for example, and tracking their journey and purchase decisions, such as buying a Pepsi.

To navigate cookieless advertising and measurement, we must prioritize building a strong foundational identity framework.

What you should focus on in a cookieless advertising era

In a cookieless advertising era, you will need to focus on two key things: frequency capping and authentic identity.

Frequency capping

Frequency capping is a practice of limiting the number of times an ad is shown to a user. This is important in cookieless advertising because it helps to prevent users from being bombarded with ads. It also helps to ensure that ads are more effective, as users are less likely to ignore or click on ads that they have seen too many times.

Frequency capping is often overhyped and yet overlooked. Instead of solely focusing on frequency, consider approaching it from an identity perspective. One solution could be to achieve a perfect balance between reaching a wider audience and avoiding excessive repetition. By increasing reach in every programmatic buy, you naturally mitigate frequency control concerns.

Authentic identity

The need for authentic identities in a digital and programmatic ecosystem is undeniable. While we explore ways to connect cookies, mobile ads, and other elements, it’s crucial to remember who we are as real individuals. By using anonymized personal identifying information (PII) as a foundation, we can derive insights about households and individuals and set effective frequency caps across different channels.

Don’t solely focus on devices and behaviors in your cookieless advertising strategy and remember the true value of people and their identities.

What’s next for cookieless advertising?

The deprecation of third-party cookies is a major challenge for the digital advertising industry. Advertisers will need to find new ways to track users and target their ads.

Here are three specific trends that we can expect to see in cookieless advertising.

First-party data is moving in-house

Many major media companies, equipped with valuable identifier and first-party data, are choosing to bring it in-house. They are focused on using their data internally rather than sharing it externally.

“Many larger media companies are opting to bring their identifier and first-party data in-house, creating more walled gardens. It seems that companies are prioritizing data control within their own walls instead of sharing it externally.”

laura manning, svp, measurement, cint

Fragmentation will continue

The number of identifiers used to track people online is growing rapidly. In an average household, over a 60-day period, there are 22 different identifiers present. This number is only going to increase as we move away from cookies and toward other identifiers.

This fragmentation makes it difficult to track people accurately and deliver targeted advertising. This means that we need new identity solutions that can help make sense of these new identifiers and provide a more accurate view of people.

A portfolio of solutions will address signal loss

Advertisers are taking a variety of approaches to cookieless advertising. A few of the solutions include:

  • Working with alternative IDs.This refers to using alternative identifiers to cookies, such as mobile device IDs or email addresses. These identifiers can be used to track people across different websites and devices, even without cookies.
  • Working with data index at a geo level. This refers to using data from a third-party provider to get a better understanding of people’s location. This information can be used to target ads more effectively.
  • Working with publisher first-party data that’s been aggregated to a cohort level. This refers to using data that is collected directly from publishers, such as website traffic data or purchase history. This data can be used to create more personalized ads.
  • Working with contextual solutions. This refers to using contextual data, such as the content of a website or the weather, to target ads. This can help to ensure that ads are relevant to the user’s interests.

“Cookie deprecation is often exaggerated, and alternate solutions are already emerging. As data moves closer to publishers and first-party data gains prominence, the industry will adapt to the changes.”

mark walker, ceo, direct digital holdings

There is no one-size-fits-all solution for cookies, and you will need to be flexible and adopt a variety of different approaches.

How will these solutions work together?

You can take a waterfall approach to cookieless advertising. A waterfall approach is a process where advertisers bid on ad impressions in sequential order. The first advertiser to meet the minimum bid price wins the impression.

In the context of cookieless advertising, a waterfall approach can be used to prioritize different targeting signals. For example, you might start by bidding on impressions that have a Ramp ID, then move on to impressions that have a geo-contextual signal, and finally bid on impressions that have no signal at all.

This is a flexible approach that can be adapted to different needs and budgets.

How audio finds audiences with Audacy

We spend our days surrounded by screens: at work, at home, and everywhere in between. But audio is the one channel that moves with us, from morning routines to evening commutes, from workouts to household chores. More than two-thirds of U.S. consumers will listen to digital audio every month this year, making it one of the fastest-growing ways to connect with audiences. Experian and Audacy are working together to solve the challenges of fragmented listening, cross-platform targeting, and campaign measurement, helping brands reach people in the moments other channels can’t. Why audio sticks with us Audio fits into life’s in-between moments, from the commute to the workout to the chores, when other media can’t. Unlike video, it doesn’t demand full attention; it joins the flow of daily routines. This makes audio uniquely personal, creating connections that other formats can’t replicate. Audacy’s expertise in understanding listener behavior ensures that audio campaigns feel like a natural part of daily life. Experian\’s data helps advertisers identify the right audiences, while Audacy ensures the message is delivered at the right time. Together, we help brands create campaigns that resonate deeply with listeners. By meeting audiences in their moments of focus, audio becomes a powerful tool for building meaningful and lasting connections. \”Audio is a companion in people’s daily rituals. Whether it’s doing dishes, folding laundry, or going for a run, you have audio going in your ears, and you’re really engaged with it. From an advertising perspective, that’s incredibly powerful because listeners are paying attention to the content.”Kevin Greenwald, SVP of Advertising and Audience Products Making sense of scattered listening habits Today’s listeners consume audio across a variety of devices and platforms. Devices like smart speakers and smart home hubs now account for over 27% of digital audio time spent daily among U.S. adults, highlighting the growing role of connected devices in audio consumption. When listeners bounce between apps, stations, and devices, it’s easy for advertisers to lose track of them. Audacy’s advanced platform capabilities, combined with Experian’s identity solutions, simplify this process by providing a unified view of audience behavior, ensuring campaigns remain cohesive.  Audio is highly adaptable, letting advertisers tweak a message on the fly by shifting tone, length, or format to stay relevant in the moment. This flexibility ensures that campaigns remain cohesive and impactful, no matter where or how listeners engage. “Audio has a degree of flexibility that other channels don’t. You’re not tied to a programming clock, and ad lengths can vary. It’s also easy to create a great audio ad quickly, which makes it a channel ripe for experimentation and innovation.”Kevin Greenwald, SVP of Advertising and Audience Products Following listeners wherever they go Today’s listeners don’t stay in one place: they bounce from live radio in the morning to streaming music during the day, then wind down with a favorite podcast at night. For advertisers, that creates a challenge: how do you keep up with an audience that’s always moving? Without a unified view of the listener journey, campaigns can lose impact. With the right insights, though, every handoff becomes an opportunity to stay relevant and connected. Audacy’s platform, combined with Experian’s identity solutions, bridges these gaps. Together, we help you follow your audience wherever they go, creating consistent experiences that drive results. This approach improves targeting and ensures that messages remain impactful. \”I hope that there’s a day coming where we can understand ad exposure in the car as well as more cars are connected and things like that. That would be really powerful.\”Kevin Greenwald, SVP of Advertising and Audience Products Your audience is listening, let\’s make sure they hear you Audio helps you connect with your audience in moments other channels miss.

From data to delivery: PurpleLab® audiences are now live in Experian’s data marketplace and Audigent curated deals

Reach de-identified patient and provider segments at scale across every channel.  Pharmaceutical brands and media platforms, including connected TV (CTV), can activate HIPAA-compliant audiences built on real-world clinical and claims data through a new collaboration between PurpleLab and Experian. Targeting de-identified audiences is essential for engaging the right patients at pivotal moments in their health journey, maximizing ROI while safeguarding privacy and improving outcomes. Overall, prescription drugmakers spent $2.97 billion on national TV advertising in the first half of 2025, a 12.2% year-over-year increase, underscoring the growing demand for scalable, privacy-compliant healthcare advertising in premium media environments.  Now, whether you\’re a pharma advertiser launching a new therapy or a platform curating health-focused inventory, PurpleLab’s integration refreshes the media planning ecosystem, offering marketers easier access to the audiences needed to drive impact. Activate with accuracy and scale PurpleLab’s de-identified healthcare segments, categorized by condition, treatment, specialty, and prescription behavior, are now accessible through Experian\’s data marketplace, streamlining media planning. This integration enables PurpleLab’s privacy-safe audiences to travel from discovery to omnichannel delivery. Experian then handles onboarding, activation, and audience expansion, in accordance with HIPAA and with industry standards. Utilizing Experian’s identity graph, spanning household and individual-level insights, as well as marketing attributes, these healthcare audiences can be: Onboarded securely, matching hashed emails or tokens to digital identifiers Activated across major channels, including CTV, mobile, display, and social Expanded with confidence, reaching more of the target population, patients, or healthcare professionals, without relying on third-party cookies This infrastructure unlocks greater scale and completeness for niche pharma audiences that have historically been hard to reach in digital and streaming environments. For brands navigating fragmented media and tightening privacy regulations, this collaboration provides the clarity and consistency they’ve been seeking. “We know healthcare marketers are under pressure to get it right: to respect privacy, be accurate, and scale. That’s why we’re excited to bring PurpleLab audiences into the Experian data marketplace and make them available through Audigent’s curated deals. It gives pharmaceutical brands and platforms a clear way to plan and measure campaigns, with the assurance that they’re reaching patients and providers when it matters in the right way.”Kim Gilberti, General Manager Curation through Audigent: Premium supply meets premium data For advertisers seeking turnkey media solutions, PurpleLab audiences are now also available through Audigent’s curated deals. Audigent’s curated deals simplify media buying by packaging PurpleLab’s clinically grounded audiences with premium, brand-safe inventory, thus creating a unified package. Instead of stitching together data and supply separately, media buyers can now access pre-built or custom-curated media deals where PurpleLab audiences are already integrated, ideal for health and wellness programming, premium CTV, or contextual content aligned to therapeutic areas. This approach gives marketers both efficiency and accuracy, streamlining execution while maintaining compliance and relevance. “Bringing together PurpleLab’s clinically precise audiences with Experian’s powerful identity and activation capabilities, and pairing it with Audigent’s premium inventory, gives advertisers more than a turnkey solution. It’s the power to launch campaigns that truly resonate, with data and media working in harmony from day one to deliver both efficiency and impact.\”Scott Ronay, VP, Advertising Sales Real-world use cases: Accuracy with purpose CTV awareness for cardiovascular therapies A cardiovascular brand is launching a CTV campaign to reach healthcare providers involved in treatment decisions. Using PurpleLab’s provider-level segments from the Experian data marketplace, a brand can activate audiences across brand-safe, streaming environments. This strategy enables meaningful engagement with prescribers while maintaining scale and compliance across CTV and complementary digital channels. Cross-device activation for high-impact health campaigns A biotech firm promoting a new therapy needs to reach patients who are likely to have a relevant condition, based on modeled audience segments. Using PurpleLab’s real-world patient segments, the advertiser activates across mobile, display, and CTV, with Experian’s identity graph ensuring household-level consistency across devices. Privacy and scale are preserved, while the brand ensures it’s not wasting impressions on ineligible or misaligned audiences. Closed-loop measurement, built for healthcare Beyond targeting, the PurpleLab–Experian integration empowers advertisers to measure real-world outcomes, not just digital proxies. By utilizing tokenization, Experian enables ad exposure data to be securely matched back to de-identified health events within PurpleLab’s platform. This means marketers can assess outcomes such as: Prescription lift among exposed vs. unexposed audiences Healthcare professional engagement and treatment initiation Patient adherence or follow-through behavior This type of closed-loop reporting is critical in pharma, where traditional metrics like clicks or impressions do not reflect business impact. Now, with token-based match-back, brands can see whether their campaigns are driving real results, securely and compliantly. Ready to reach the right patients and providers securely and at scale? Explore PurpleLab audiences in the Experian data marketplace and Audigent curated deals to activate clinically grounded, privacy-compliant segments across CTV, display, mobile, and more.

What’s curation in AdTech?

Programmatic media buying isn’t getting any easier. Buyers face rising signal loss, shrinking margins, and growing pressure to perform in a privacy-first world. Add in fragmented tech, shifting privacy regulations, and inconsistent identity signals, and reaching the right audience at scale has never been more complex (or costly). Meanwhile, advertisers demand more transparency, publishers want control, and consumers expect relevance without feeling watched. Open exchanges, legacy data management platforms (DMPs), and spray-and-pray strategies just aren’t cutting it. That’s why curation has become a trending topic in the AdTech space. In programmatic advertising, curation refers to the strategic integration of enriched data and quality inventory into a single package — often executed as a private marketplace (PMP) deal. This approach reshapes how campaigns are built, activated, and optimized by enabling performance-ready buys that reduce waste, increase relevance, and give marketers greater control over outcomes. It’s no wonder then that curation investments are accelerating, PMPs are gaining traction, and buyers are shifting budgets accordingly. Over 66% of the $150 billion+ open exchange programmatic market now flows through curated PMPs, with industry giants like Google publicly backing curation as a core strategy. So what exactly is programmatic curation, and why is it becoming essential for privacy-conscious, performance-driven marketers? Let’s break it down. What does programmatic curation mean in AdTech? Programmatic curation is the process of filtering, structuring, and packaging enriched data with high-quality programmatic inventory — enhanced by real-time optimization to create more targeted, efficient, and transparent media buys. Instead of buying at scale and hoping for the best, curation prioritizes accuracy and value over volume, resulting in more targeted, efficient, and transparent media buys. As privacy regulations reshape targeting, curation is becoming a key differentiator in an increasingly crowded AdTech space. It connects robust data with quality supply, helping marketers stay effective while giving publishers new ways to monetize with control. But not all curation is created equal. Programmatic curation requires three core elements: 1. Unique data Unique, privacy-compliant, and valuable. 2. Strong supply connections Access to quality inventory from publishers at scale. 3. Optimization tools To measure, refine, and improve performance during a campaign and improve performance throughout the campaign lifecycle. Without all of these elements, a so-called “curator” may simply be repackaging inventory without delivering the full value of a curated approach. Why does curation still matter with cookies sticking around? While third-party cookies and mobile IDs like IDFA haven’t gone away, the industry has already pivoted in anticipation of their decline.  Even without Google flipping the switch, signal loss is here thanks to Apple’s ATT, tighter compliance rules, and new tracking restrictions. Marketers are dealing with less data, more fragmentation, and fewer reliable IDs. So if you want to run an effective, scalable media campaign today, you need tools that go beyond third-party cookies. That’s why programmatic curation is gaining ground as a better, more sustainable way to buy media. Investments in programmatic curation are growing, and not just for identity resolution. Marketers are leaning in because it: Combines verified audience data with premium inventory Supports ID-free or context-aware targeting Enables scalable, identity-agnostic strategies Improves data quality through enrichment Creates more controlled, pre-approved media paths via PMPs Experts anticipate that, at some point, publishers will have to lean into this method. “Curation will be bigger than header bidding and as big as programmatic or RTB — that’s our bet.”Andrew Casale, CEO Whether cookies stay or go in the future, curation works for an ecosystem that demands smarter, cleaner, and adaptable media buying. What are the benefits of curation and who wins? Curation is one of the few innovations in AdTech delivering meaningful wins across the ecosystem. By bringing better data, cleaner supply, and more intentional targeting into programmatic advertising, it helps brands, agencies, and media buyers drive stronger performance, gives publishers more control, and creates a more respectful experience for consumers. And unlike traditional approaches, curation is built for what’s now and what’s next. Here’s how each group benefits and why it matters. Brands and agencies Curation helps brands and agencies run smarter, more efficient campaigns by connecting high-quality data with premium supply. It delivers: More efficient supply paths with less waste and better performance Lower costs than DMP segments and open exchange buys Cleaner, pre-vetted inventory that aligns with audience and brand goals Future-proofed buying via cookieless and log-level data integrations Stronger targeting and measurement driven by enriched data and actual usage signals instead of modeled assumptions Better outcomes through real-time supply and data optimization Publishers For publishers, curation makes inventory more addressable without giving up control. It enables: Smarter packaging that aligns with buyer needs and campaign goals Higher CPMs by curating inventory above open exchange floors More control over how audiences are accessed and how inventory is monetized Access to higher-value demand through curated, data-backed deals Better protection of proprietary audience in a privacy-conscious environment Consumers At the end of the chain, curation improves the ad experience for those who matter most: your audience. It supports: Higher-quality content alignment for more natural, less disruptive ad experiences tailored to their interests  Less invasive tracking, as targeting becomes more data-smart and privacy-aware, with reduced reliance on legacy identifiers and personally identifiable information (PII). Curation is setting a new standard for how data, inventory, and experience come together across the ad ecosystem. When media is smarter, cleaner, and more intentional, everyone wins. What’s Experian’s role in powering curation? With the acquisition of Audigent, Experian is now more than just a premier data provider. We’re also a full-service curation partner.
