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.

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.

Retail media networks (RMNs) rank among the fastest-growing media channels. According to eMarketer, retail media spend is forecasted to account for more than a fifth of overall digital spending in 2025, and retail media spend will grow by 21.8%. For RMNs, the path to realizing this opportunity is marked by navigating through a series of critical stages, each with its own set of challenges and solutions. Retail media strategies Simply put, RMNs need to know who their customers are, where they are, and how to reach them to succeed. But we know nothing is that simple. This blog post reviews the three pivotal stages of RMN success, offering a roadmap for networks aiming to optimize their operations and claim their share of the rapidly growing category. Stage 1: Develop a data foundation In a world where traditional tracking methods are fading, first-party data has become essential for targeted advertising. Retailers have a wealth of this valuable data due to their direct consumer relationships. The initial step in establishing an RMN is to organize and utilize this data effectively. Steps to develop a data foundation: Organize data: Bring together fragmented shopper data, loyalty program information, and other customer data into a unified location. Clean and deduplicate this data to create consistent customer profiles. Enhance profiles: Gain insights into your customers and your brand’s customers so you can learn who your best, lapsed, and non-customers are. Append additional attributes to your shopper data, including media consumption habits, lifestyle preferences, demographic information, and more. Use identity graphs: Identity providers, like Experian, enable you to learn about the anonymous – and known – visitors on your platform and organize disparate customer data points into households. This will allow RMNs to connect addressable identifiers to the household, making it easier to reach customers across channels. Create audience segments: With a solid data foundation, RMNs can build audience segments beyond basic shopper data. These segments will make your data more attractive and actionable for media buyers. For example, consider a retailer that knows its shoppers are primarily young professionals, but a CPG brand wants to target not only these shoppers but also young professionals who are parents. By partnering with an identity solution provider like Experian, the retailer can append additional data to identify and target the young parents within their existing customer base, enabling the CPG brand to reach both audience segments effectively. “Retail media networks thrive on clean, accurate, and actionable data. Simply put, it's crucial to know who your customers are, when they're most engaged, and where to reach them to drive effective marketing strategies and maximize ROI.”anne passon, sr. director, sales, retail Stage 2: Become a publisher for optimal retail media growth The next step for RMNs is to transition from building a data foundation to helping marketers reach their target audience, essentially becoming a publisher. This involves two main processes: organizing advertising inventory and connecting it to demand. Steps to become a publisher: Audit and organize inventory: Conduct a thorough review of all existing ad spaces, including websites, apps, and in-store placements. Identify gaps and consider creating new advertising opportunities, such as website and app features, interactive digital experiences, or expanded in-store touchpoints. Connect inventory to demand: Integrate the organized inventory with platforms, allowing advertisers to access it easily. This often involves using supply-side platforms (SSPs) and demand-side platforms (DSPs). Continuing with our example, the CPG brand can work with its DSP or SSP partners and easily access your ad inventory, and effectively target the young professional and young parent audience segments. Stage 3: Scale inventory for retail media growth As RMNs progress to the final stage of their success journey, they may face the challenge of limited inventory within their owned and operated (O&O) channels. To meet marketers' expansive reach requirements and to continue to drive growth and profitability for their organizations, RMNs must expand their inventory beyond O&O. Steps to scale inventory: Utilize data collaboration tools: Clean rooms allow secure merging and enrichment of data from various sources, creating richer audience profiles while maintaining privacy. Resolve identity and enhance addressability: Identity graphs help resolve known customer identifiers (e.g. emails) into addressable IDs (e.g. mobile IDs and connected TV IDs), which can be used to reach customers across all the platforms they consume media. Expand audience reach: Onboarders, like Experian, help extend data and audiences to programmatic destinations beyond a retailer's O&O inventory. By mapping audiences to digital identifiers maintained by identity partners, RMNs can significantly widen their reach, meeting advertisers' needs for engaging with broader and more diverse audience segments. The CPG brand can now reach young professionals and young parents on the retailer’s platform and in all the other places where they consume media, like watching their favorite shows on connected TV (CTV) or browsing the web on their phones. Measurement across stages for retail media growth Measurement is crucial and must be conducted during and after a campaign to understand and validate performance. Here are two types of measurement to consider: Cross-device campaign measurement: Measure performance by connecting an ad exposure in one environment (e.g. CTV) to an action in another (e.g. mobile purchase). This holistic, cross-device approach requires a partner for identity resolution as it will ensure that the impact of a campaign is fully understood. Aggregate performance analysis: Understand performance in aggregate across several campaign studies. Receive independent third-party measurement validation that you can promote to advertisers to drive increased spend. For our CPG brand, these measurement reports ensure that they can track the performance of their campaigns from the initial exposure on a CTV to the final purchase made on a mobile device, providing comprehensive insights and validation of their advertising strategy. The retailer can aggregate these studies and promote their network’s effectiveness to prospective advertisers. Accelerate retail media growth with strategic partnerships The journey through the stages of RMN success is riddled with deep technical challenges that are often beyond the institutional capabilities of non-media businesses. The intricacies of data management, audience insights, identity resolution, precise cross-device targeting, and measurement require specialized expertise and technologies that may not be readily available in-house. RMNs stand to benefit from forging strategic partnerships with companies that possess not only the necessary technological tools but also a profound understanding of the media landscape. The steps outlined here will accelerate your growth and ensure you capitalize on the opportunity in front of you.

Get ready for Cannes Lions 2024—the advertising industry is buzzing with excitement. This year's event promises to be a center of innovation, ideas, and networking. Here are five themes we expect will take center stage in conversations and how Experian can help marketers be prepared for what’s ahead. Cookie deprecation and signal loss At Cannes Lions 2024, the theme of transitioning to a cookieless advertising ecosystem is likely to dominate discussions. The saga of cookie deprecation continues to unfold, with Google recently pushing back the demise of third-party cookies once again. Experian remains fully committed to prioritizing continued testing of different industry solutions, including the Google Privacy Sandbox, to help customers prepare for a future without cookies. We've identified six viable alternatives to third-party cookies, how these alternatives fall short, and how Experian can help you navigate these alternatives. With Experian, the loss of cookies does not equate to a loss of coverage. With our strong roots in offline data and significant investments in our Graph, Experian ensures uninterrupted and effective marketing with robust signal coverage, with or without cookies. Based on early tests, we expect our Graph to maintain 97% of its household coverage. Read how MiQ, a leader in the cookieless era, strengthened its Identity Spine with the integration of Experian’s cross-device Graph here. Commerce The theme of commerce is poised to be a central topic of discussion at Cannes Lions 2024, reflecting the emergence and growth of retail media networks (RMNs). Evolving customer expectations are a key driver, with consumers demanding seamless and personalized experiences across all touchpoints of their shopping journey. The importance of bridging physical and digital experiences to create a cohesive customer journey will undoubtedly feature prominently in discussions at Cannes. Experian's Consumer Sync offerings facilitate seamless integration between online and in-person interactions, fostering a cohesive approach to engaging audiences across various platforms while measuring campaign effectiveness. As we heard at Shoptalk 2024, the evolution of retail media is propelling us into a new era of advertising and first-party data monetization. The integration of e-commerce with advertising presents an exciting opportunity for brands to drive direct sales through ads displayed within retail platforms, blurring the lines between marketing and commerce. Our Consumer View solutions provide access to over 5,000 demographic and behavioral data points, enriching your customer profiles for deeper insights. By combining first-party data with Experian's industry-leading data sets, you can create bespoke audience segments that drive increased return on investment (ROI), going beyond conventional category-based targeting strategies. Looking ahead, the future outlook for RMNs remains promising, with anticipated growth and expansion as brands increasingly recognize the value of reaching consumers precisely at the point of purchase. Connected TV At Cannes Lions 2024, we anticipate discussions to focus on how connected TV (CTV) can continue to live up to its promise. CTV is the most rapidly expanding advertising channel in the U.S and 95% of advertisers plan to increase their share of spend on programmatic CTV in 2024, according to The Trade Desk's latest CTV report. The growing adoption of CTV among viewers, driven by factors like quality content, reduced ad interruptions, and cost-saving alternatives to traditional cable, signals a shift in consumer behavior that marketers cannot afford to overlook. Experian supports the growth of advertising interest in CTV through our signal-agnostic Graph that connects CTV IDs, universal IDs like Unified I.D. 2.0 (UID2), IPs, and mobile ad IDs (MAIDs) for effective activation. Our digital identity resolution with Activity Feed provides insights into CTV viewership behavior, linking CTV exposure to e-commerce conversions. CTV also enables greater collaboration, and we've recently announced new partnerships with CTV industry leaders Microsoft, Samsung, Attain, Sonobi, and EDO. Consumer privacy Consumers are increasingly aware of privacy concerns surrounding their data and numerous laws are going into effect across the U.S. at the state level. Most recently, there has been momentum on a federal data privacy law. We expect consumer privacy to be a significant topic of discussion at Cannes Lions 2024, reflecting the growing importance of ethical data practices in advertising. In a recent Q&A with Datavant, Jeremy Meade, VP of Marketing Data & Product Operations at Experian, highlights the importance of balancing data privacy and utility, focusing on "data for good" practices while using de-identification techniques to support research without compromising consumer privacy. Our Geo-Indexed audiences are an example of how Experian can help you reach your audience while balancing data privacy and accuracy. Our Geo-Indexed audiences combine location data with audience insights to deliver targeted marketing solutions. These audiences are created without the use of sensitive personal information, so you can confidently reach your target audience without sacrificing data privacy. With deep roots in data protection and security, you can confidently partner with Experian as we proactively stay ahead of regulations and strictly follow all consumer privacy laws. Campaigns and competition The theme of campaigns and competition is poised to be an important discussion point, driven by the convergence of major global events like the U.S. presidential election and this summer’s games—both occurring once every four years. These landmark occasions present opportunities for marketers to craft targeted campaigns that resonate with specific audience segments. As we approach the 2024 election season, the advertising landscape is primed for growth, with political ad spending projected to exceed $10 billion. Effective audience targeting during this crucial period can sway voters, shape public opinion, and influence election outcomes. Experian's 240+ politically relevant syndicated audiences, including our 10 political personas, enable a nuanced understanding of voter viewpoints and empower tailored engagement strategies to connect more effectively with constituents. At the same time, this summer’s games in Paris offer a unique opportunity for sports marketing. With one billion viewers expected to tune in, the global spectacle presents a platform to engage with passionate sports audiences worldwide. Using Experian's syndicated audiences, marketers can precisely target sporting goods shoppers, avid fans, athletes, and spectators alike. The combination of these major events emphasizes the need for careful planning and data-driven strategies and marketers should take advantage of the excitement surrounding both events.
