Third-party cookies have been the foundation of targeted advertising for a long time. Around 75% of marketers worldwide rely on third-party cookies, with approximately 42.2% of websites using them to gather user data. These tiny bits of code silently track our online activities, collecting search history and product preferences to help advertisers tailor their campaigns to our needs.
However, as fears over online privacy have grown, the third-party cookie era is ending. Most American consumers are worried about data privacy when engaging with brands online. Privacy concerns are widespread across all age groups, with 82.7% of 18- to 24-year-olds and 87.8% of 55- to 65-year-olds expressing apprehension about how their data is handled, according to eMarketer.
While some other search engines have already eliminated third-party cookies, Google Chrome — which holds 65% of the global browser market — is just beginning to phase them out as new alternatives are tested. Google’s third-party cookie deprecation is expected to impact marketers in a big way.
Let’s talk about what that impact will look like and how marketers can reconcile consumer demands for browsing privacy with their preference for personalized ad experiences.
What is cookie deprecation?
Cookie deprecation is a process where web browsers, like Google Chrome, phase out the use of a specific cookie type. In the context of this article, we’re referring to third-party cookies, small pieces of data stored on a device by websites a person visits.
Advertisers and other companies use third-party cookies to track a person’s actions on the web. They help those companies learn about an individual’s interests and show them targeted ads. But over time, internet users have become more aware of cookies and how much companies know about them, so browsers are phasing out third-party cookies to respect user privacy.
The timeline and reasons behind the shift
In January 2020, Google announced it would no longer allow third-party marketing cookies by 2022. Realizing it needed to find an alternative first, it pushed the deadline back several times over the years, eventually confirming that third-party cookies would be deprecated by the end of 2024 — a big deal for the advertising industry. So, what’s the motivation behind this change?
Many people are becoming increasingly worried about online privacy and the intrusiveness of third-party cookies. In recent years, lawmakers have pressured tech companies to make changes in response to their constituents’ concerns about online privacy rights. By getting rid of third-party cookies, browsers like Chrome are trying to give users more control over their data and respect privacy demands to create a more privacy-friendly browsing experience.
This shift is part of a broader trend in the digital world toward greater privacy protections, with browsers like Firefox and Safari having already phased out third-party cookies. We’ve also seen other significant moves in this direction, including the following. These regulatory efforts reflect a growing awareness of how important it is to protect data privacy and consumer rights in a world gone digital.
- Apple’s App Tracking Transparency (ATT) framework was introduced in iOS 14.5, requiring users to get permission before tracking their data across other apps or websites.
- The Global Privacy Control (GPC) strives to improve users’ control over their internet privacy by letting them signal their preferences for data sharing.
- Europe’s General Data Protection Regulation (GDPR) and California’s Consumer Privacy Act (CCPA) have strict guidelines for how companies handle personal data to prioritize transparency and user consent.
Google’s most popular browser, Chrome, recently made its first big move toward third-party cookie deprecation. On January 4, 2024, Google announced the rollout of a new “Tracking Protection” feature, limiting cross-site tracking by default. They’re doing this gradually, activating the feature for 1% of random Chrome users worldwide, about 30 million people.
Google Chrome’s cookie phase-out impact
Chrome’s third-party cookie deprecation is expected to have the farthest-reaching consequences for marketers like you, as it has almost two-thirds of the browser market worldwide. It’s important to note that this phase-out specifically targets third-party cookies, not first-party cookies, which are generated and stored by the website a user visits directly and will be unaffected by this change.
Here are a few of the impacts to prepare for.
Reduced tracking capabilities
Once third-party cookies are eliminated, you may face challenges in understanding consumer behavior across different websites. Without this tracking capability, understanding your audiences and effectively tailoring advertising campaigns might become more difficult.
Required shift in strategy
It will be key for you to adapt your advertising strategies to rely less on third-party data and more on alternative targeting methods. This shift may involve greater emphasis on contextual advertising, which targets people based on the content of the websites they visit instead of browsing history, and first-party data gathered directly from site users to personalize advertising campaigns.
Additionally, in order to move beyond reliance on cookies and third-party identifiers, activation platforms like demand-side platforms (DSPs) must evolve to identify addressable IDs within bid streams. This adaptability is essential as digital advertising shifts toward privacy and cookieless environments. By being able to recognize addressable IDs in bid streams, DSPs can help facilitate more accurate, personalized targeting and help advertisers reach their audiences across channels and devices without privacy concerns. As a marketer, you should understand the capabilities of your chosen platforms and inquire about their support for evolving targeting methods and data sources.
New compliance regulations
By limiting the ability to track users across the web, Google aims to enhance user privacy and control over their data. You’ll need to embrace privacy-centric approaches to advertising to comply with evolving privacy regulations and build trust with consumers.
Challenges posed by Google’s cookie deprecation in 2024
Marketers are responding to the announcement of third-party cookie deprecation with an eye toward innovation as they proactively seek new solutions. As of early 2024, 56% of marketers in the United States were testing cookieless alternatives. Knowing their customer acquisition will be less efficient without these cookies, they’re looking for ways to maximize the value of their existing customers, increase retention, and make better use of first-party data. Others have been slow to react due to a lack of awareness or uncertainty about how to handle the changes.
Here are some additional challenges advertisers can expect to face as third-party cookies begin to be phased out.
Impact on targeting and personalization
The decline of third-party cookies is expected to have a major impact on targeting and personalization strategies. As advertisers will no longer have access to individual browsing histories, some may struggle to reach specific audiences and deliver personalized content. As a result, they have begun to explore using first-party data and contextual targeting to preserve relevance and consumer engagement.
Attribution and measurement challenges
The future removal of third-party cookies may also make it harder to measure the effectiveness of advertising and accurately attribute conversions. Marketers are currently searching for reliable alternatives to track users across channels and touchpoints. Google’s Attribution Reporting API and private aggregation methods are being explored as potential solutions to these attribution and measurement challenges.
Data privacy and compliance challenges
Future third-party cookie deprecation makes data privacy and compliance a top priority. With the introduction of stricter regulations like GDPR and CCPA, you need to ensure your data collection and usage practices comply with privacy laws. To maintain the trust of consumers and abide by regulatory requirements, it has become essential to shift toward first-party data collection and more transparent consent mechanisms.
Lack of resources to invest in alternative solutions
One of the main challenges advertisers will face with future cookie deprecation is a lack of resources to invest in alternative solutions. Many businesses don’t have the financial resources or technical expertise to explore and implement new targeting and measurement methods.
Additionally, some companies have been reluctant to adopt new solutions because they want to thoroughly test and evaluate their efficacy. The fear of investing resources in unproven technologies or strategies has led to a cautious approach among marketers and advertisers. However, this reluctance to adapt could hinder their ability to remain competitive.
Many companies may also face logistical challenges due to the complexity of transitioning from reliance on third-party cookies to alternative data sources and targeting methods. Integrating new technologies, adjusting workflows, and retraining staff requires time and effort, adding to the complexity of the transition.
Adapting to a cookieless world
Even though third-party cookies are going away, you still have other types of data in your arsenal to help you continue reaching your audience.
Use first-party data
First-party data, collected from customers or website visitors directly, offers valuable insights into consumer behavior and preferences. By investing in proven data collection methods and analytics tools, you can understand your audience more accurately and tailor your messaging and targeting accordingly.

Discover alternative targeting technologies
As third-party cookies become obsolete, marketers are starting to investigate alternative targeting technologies for optimizing campaigns. These may include contextual targeting, which focuses on the content and context of a user’s web browsing activity, as well as emerging solutions like cohort-based targeting, which groups users based on shared interests and behaviors. Think of third-party cookie deprecation as the opportunity to innovate and rethink strategies that have relied too heavily on one type of technology.
Best practices for marketers in the post-cookie era
Embracing best practices for a privacy-centric advertising environment can help you maintain your effectiveness and thrive in a cookieless world. Let’s talk strategies to help you succeed in the post-cookie era.
Focus on customer consent and transparency
Having consumers opt-in to sharing their data is an excellent way to build your data pool ethically. One way to do this is by encouraging users to create accounts or log in to access exclusive content or features while providing valuable information in exchange for their data. Another way is by conducting surveys or quizzes to gather insights directly from users about their preferences, interests, and behaviors. You could also use interactive content like polls and contests to engage users and collect data. These approaches can enrich your data pool while demonstrating your commitment to respecting user privacy and preferences.
Prioritize obtaining explicit consent from users before using or gathering their data for your advertising. Implement transparent data practices by clearly communicating to consumers how you’ll use their data and providing easily accessible options to manage their privacy preferences. By building trust through transparency and respecting user choices, you can forge stronger relationships with your audience.
Enhance the customer experience with quality data
In the future absence of third-party cookies, first-party data will be paramount in helping you understand and engage with your audience effectively. Invest in strategies that will help you collect high-quality data directly from customers, such as through interactive content, preference centers, and loyalty programs. By obtaining and using accurate, relevant data, you can provide personalized experiences that resonate with audiences and drive meaningful engagement.
Collaborate with evolving technology platforms
As Google’s cookie deprecation reshapes advertising, it will be important to collaborate closely with technology providers and key industry players who are adapting to these changes. Make sure your chosen platforms are keeping up with the industry and offering solutions that align with the shift to cookieless environments. Partnering with platforms that are proactively addressing these challenges will make it easier to navigate the changing marketing environment and drive better results for consumers and campaigns.

Audio platforms that overcome consumer identity challenges are winning new advertisers and driving higher ROAS. In this article, you’ll hear from leading audio platforms that are solving these challenges—and seeing results. Digital audio is evolving fast. What was once a niche channel of host-read sponsorships and direct buys is now a must-have in the modern media mix. Streaming platforms, podcasts, and digital radio are drawing more ad dollars thanks to audio’s ability to capture attention and connect with listeners. But with growth comes new pressure. Advertisers expect accuracy, scale, and to see results. At the same time, listeners want more relevant content and more personalized ad experiences. That’s where identity becomes essential. With Experian’s identity and audience solutions, audio platforms can: Bolster addressable audience targeting and personalization capabilities. Gain a comprehensive view of listeners’ digital identity to reach audiences across channels. Better understand consumer preferences, enabling advertisers to reach audiences with greater accuracy. Enhance the listening experience with more relevant content. Let’s break down the key challenges in audio—and how Experian can help solve them. Challenge 1: Anonymous listening limits addressability Most listening happens in environments where people aren’t logged in—via apps, smart speakers, and mobile devices. Without logged-in data, platforms struggle to know who’s listening and advertisers are unable to reach those anonymous listeners who don’t have an addressable ID. To overcome the identity gap in unauthenticated listening environments, leading audio platforms are turning to partners that connect fragmented signals—like device type, location, and behavioral patterns—to broader household and individual profiles. By using hashed emails and other alternative identifiers, platforms can begin to make anonymous sessions more addressable. This increase in addressability ensures the platform’s entire userbase can be reached, which leads to an increase in revenue. Experian’s solution Experian's identity spine, comprised of our Digital and Offline Graphs, helps you recognize listeners even when they’re outside your ecosystem. Platforms like Audacy are already leading the way. By integrating Experian’s Digital Graph, they’re gaining a more complete view of listeners’ digital identifiers—enhancing the experience across their app and website. With a better audience understanding, Audacy can deliver personalized content while helping advertisers reach specific groups with greater accuracy. Challenge 2: IP-based targeting falls short Audio has traditionally relied on IP addresses, but that’s no longer enough. A single IP could represent an entire household—or a public setting like a coffee shop. It’s not precise. Forward-thinking platforms are moving beyond IP-based targeting by integrating identity resolution technologies that combine household-level data with device-level intelligence. These solutions help distinguish between shared devices and individual listeners, allowing advertisers to serve more relevant messages without over-reliance on a single signal like an IP address. This layered approach improves precision—especially in dynamic listening environments like vehicles or communal spaces. Experian’s solution Our identity spine links home IPs to households, then connects them to specific devices and individuals. This helps platforms move beyond basic IPs and target real people based on accurate signals—even in shared listening environments like smart speakers and cars. We also help platforms and advertisers integrate alternative IDs—like Unified I.D. 2.0 (UID2)—into their programmatic audio campaigns. That means more reach, without compromising consumer trust. Challenge 3: Audio buying is fragmented From podcasts to streaming to radio, audio lacks consistency in how inventory is packaged and bought. It’s hard for advertisers to run scaled campaigns across channels—and harder still to measure performance. Plus, advertisers don’t think in silos—they think in strategies. If audio can’t connect to their display, connected TV (CTV), and social buys, it loses ground. What they need is a way to define audiences once and activate everywhere. To reduce friction in audio ad buying, platforms are investing in infrastructure that unifies audience insights across formats. By building a centralized view of the listener—regardless of whether they're tuning in via podcast, stream, or radio—publishers can offer advertisers consistent targeting parameters, clearer reporting, and better campaign orchestration. Identity graphs and audiences are playing a growing role in streamlining this complexity and unlocking scale. Experian’s solution Experian helps simplify audio buying. Experian audiences are built on top of our identity graph and are expanded to a deep set of digital identifiers, ensuring accuracy, scale and maximum addressability across channels. Platforms can blend their first-party data with advertiser data and our audiences—then deploy those audiences onsite or activate programmatically across open web and CTV. DAX is doing just that. DAX's partnership with Experian combines Experian’s 2,400+ audiences for targeting and activation with DAX’s innovative audio advertising approach. We’re helping advertisers connect with passionate and engaged listeners nationwide. "Through our partnership with Experian Marketing Services, advertisers can unlock deeper audience insights and execute more impactful digital audio campaigns. By combining our shared market presence, knowledge, and forward-thinking approach, we’re strengthening our digital audio network offering and delivering value to all our advertising partners." Brian Conlan, President of DAX United States In addition to integrating Experian’s Digital Graph, Audacy is also integrating Experian's syndicated audiences to unlock accurate insights like demographics, shopping behavior, and interests – providing listeners with a more personalized advertising experience and advertisers with a higher return on investment. “Historically, audio advertising lacked precise targeting capabilities, making it challenging for advertisers to reach specific audiences. By integrating our digital identity graph and syndicated audiences with Audacy’s platform, we’re transforming how advertisers connect with listeners. This collaboration enables more effective audience targeting and delivers personalized, impactful audio experiences across all channels.”Chris Feo, Chief Business Officer, Experian Privacy is non-negotiable Everything we do is privacy-forward by design.

When we launched our data marketplace earlier this year, we set out to transform how the industry discovers and activates privacy-safe audiences and maintains addressability across display, mobile, and connected TV (CTV). Yieldmo was one of the first adopters and their story speaks volumes about what’s possible when flexible tech meets premium data. Large retail brand boosts in-store traffic with Yieldmo and Experian Yieldmo, an advertising platform known for its inventive, AI-powered creative formats and privacy-first inventory, partnered with Experian to support a leading athletic retailer’s campaign focused on driving in-store traffic. The goal? Attract in-store shoppers likely to purchase from competitors, particularly during key sales windows. Using Experian’s Audience Engine platform, which includes our proprietary and third-party data marketplace, Yieldmo built a high-performing, self-serve targeting strategy that included both conquesting and in-store shopper segments. With the ability to easily combine Experian Audiences and Partner Audiences, like those from Alliant, Circana, Webbula, and Sports Innovation Lab, Yieldmo quickly built precise apparel and footwear audiences. Using Experian’s identity graphs in Audience Engine, Yieldmo increased cross-channel addressability to maximize campaign scale and impact. “Experian’s data marketplace in Audience Engine fills a critical gap, letting us quickly search by brand, build smarter conquest segments, and activate custom audiences fast. The platform is flexible and the support is hands-on and reliable.”Abby Littlejohn, Director of Sales Planning at Yieldmo With self-serve setup that cut down manual work, the ability to build highly tailored audiences, and expected lift in store visits, Experian helped the team achieve standout results. "We selected Experian as our primary third-party data partner based on contract ease, audience quality, and speed. Through Experian, we can find high-performing audiences from multiple providers that meet our client’s targeting objectives. We include Experian audience segments in 80% of formal RFP proposals and are in active discussions on how to optimize for future campaigns—making Experian a go-to partner for third-party targeting.”Nelson Montouchet, AVP, Strategic Partnerships, Yieldmo More data, more reach: Experian’s data marketplace fuels smarter targeting across ad platforms Today, just months after launch, Experian’s data marketplace is gaining traction across the ecosystem. Over 10 platforms, including leading supply-side platforms (SSPs) and TV platforms such as Madhive, OpenAP, and Optimum, are now actively utilizing our data marketplace to enhance their activation capabilities. As privacy rules tighten and many identity signals start to fade, a lot of activation platforms are finding it tougher to reach their audiences. This is where our data marketplace shines, with one of the most comprehensive identity graphs out there, 126 million households, 250 million individuals, and over four billion active digital IDs, we make it easy to activate audiences while keeping addressability high across channels. We preserve accuracy when scaling to digital IDs via our identity graphs since Experian is rooted in offline data, which provides better connections and smarter targeting. “Our long-standing partnership with Experian and breadth of Experian's data marketplace, combined with the interoperable, direct matching methodology of our Open Identity solution, make it possible for OpenAP to enable advertisers and agencies to use best-in-class data partners to build audiences with the highest fidelity and consistently reach audiences at scale wherever they are consuming content across premium video.”Chris LoRusso, Chief Business Officer at OpenAP Experian’s data marketplace has grown to include over 20 premium data providers, such as: “We’re thrilled to bring PlaceIQ’s privacy-first, visit-based audiences to Experian’s marketplace, giving brands quick and easy access to high-intent shoppers. From recent big-box customers to yoga-studio regulars, advertisers can add real-world relevance to campaigns across every channel.”Brian Bradtke, Head of Partner Development, Precisely PlaceIQ These partnerships bring unique value to platforms looking to understand and engage audiences more effectively, whether through physical location intelligence, sports and fandom insights, or behavioral intent signals. What’s next We're focused on expanding our data ecosystem and helping platforms and marketers turn fragmented data strategies into a unified competitive advantage.
