Google’s third-party cookie deprecation plans are on hold, but privacy expectations continue to rise. Marketers still need identity-based, data-responsible solutions to understand and reach audiences effectively. Experian helps brands stay connected through privacy-first identity, data collaboration, and measurement solutions that perform across channels, with or without cookies.In this article…
The marketing world has been preparing for years for the end of third-party cookies, and the news has shifted again. In 2025, Google paused its plan to phase out third-party cookies in Chrome, opting instead to introduce new privacy controls that let users manage how their data is shared. Even with this change, one truth remains: privacy-first; identity-driven marketing is no longer optional. For marketers, it’s about moving beyond reliance on cookies toward durable strategies built on trust, consent, and connected data.
What is cookie deprecation?
Cookie deprecation refers to browsers ending support for third-party cookies, which have long allowed advertisers to track user activity across multiple websites. These cookies were the foundation of behavioral targeting and attribution. By contrast, first-party cookies, created by a brand’s own website, will continue to function. They store essential information like logins or preferences and are central to modern data collection strategies.
The change aims to improve privacy and transparency, giving users more control over their information. For marketers, it represents a shift from broad tracking to consented, identity-based engagement.
Experian’s view: While third-party cookies may linger longer than expected, identity should remain the cornerstone of every marketing strategy.
Why is cookie deprecation reshaping the industry?
The shift toward privacy-first marketing didn’t begin with Google, but Chrome’s decision to limit third-party cookies has amplified the impact. Safari and Firefox removed third-party tracking years ago, but Chrome’s dominance, with roughly 65 percent of the global browser market, makes its shift a defining moment for advertisers.
- Apple App Tracking Transparency (ATT): Requires user permission before app tracking.
- Global Privacy Control (GPC): Lets users signal how their data can be shared.
- General Data Protection Regulation (GDPR) and California Consumer Privacy Act (CCPA): Enforce consent and transparency in data use.
- Google Tracking Protection: Now limits cross-site tracking for 1 percent of Chrome users, about 30 million people, before a full rollout.
The platform response
Google’s Privacy Sandbox initiative and new user privacy control interface aim to balance personalization with user protection. These updates mark a shift toward data transparency rather than full deprecation.
Experian supports this evolution by helping marketers adapt through privacy-led identity, data collaboration, and measurement solutions that meet compliance standards while maintaining addressability and performance across channels.
How will cookie deprecation affect marketers?
Marketers will notice several shifts:
- Less cross-site visibility: Without third-party cookies, connecting behavior across websites becomes difficult, making it harder to attribute conversions.
- Greater dependence on first-party data: Data collected directly from consumers (emails, preferences, purchase history) will be crucial for targeting and measurement.
- Increased adoption of alternative IDs: Solutions like Experian’s alternative IDs help maintain addressability and measurement in a cookieless world.
- Renewed focus on contextual advertising: Relevance now depends on where an ad appears rather than who sees it.
- New compliance expectations: Marketers must prove transparency and respect for consent under tightening global privacy laws.
What challenges should marketers expect with cookie deprecation?
Marketers face both operational and strategic hurdles as third-party cookies lose value.
Addressability and targeting gaps
Without universal identifiers, reaching audiences across channels becomes fragmented. Advertisers must unify data from CRM systems, mobile apps, and offline touchpoints to maintain reach.
Measurement and attribution complexity
As cookies disappear, so do last-click and view-through models. Solutions must rely on first-party data and probabilistic modeling to evaluate performance.
Privacy and consent management
Data collection now requires clear opt-ins, user control interfaces, and secure consent management systems that align with IAB standards.
Resource and skill constraints
Testing new identity and data solutions can be costly. Smaller teams may struggle to integrate clean rooms, universal IDs, or new reporting APIs.
Experian’s role: Experian supports marketers through this transition with privacy-compliant data infrastructure, identity graphs, and measurement tools that work across every major platform.
How can marketers adapt to a cookieless future?
Cookies may still exist, but durable identity strategies are the future of digital marketing. Here’s how to prepare:
- Use first-party data: Collect information directly from your customers through loyalty programs, preference centers, and interactive content.
Invest in analytics that translate this data into insight. - Establish a trusted identity foundation: Experian’s Digital Graph connects more than 4.2 billion digital identifiers, linking households and devices in privacy-compliant ways. That means marketers can expand their addressable reach and understand audiences without relying on cookies. Experian’s data-collaboration solutions let you combine your first-party data with partner insights securely, unlocking deeper audience understanding.
- Explore alternative targeting technologies: Contextual methods powered by Experian’s data accuracy ranked #1 by Truthset, help you maintain personalization while respecting privacy.

What are the best practices for post-cookie marketing?
- Be transparent: Make consent simple and clear, and show how data adds value. Experian helps brands maintain transparency through privacy-first data solutions built on consented consumer information.
- Prioritize data quality: High-quality, verified data builds confidence and improves ROI. Experian’s accurate and validated data assets ensure marketers reach real people with relevant messages.
- Choose the right partners: Work with technology providers like Experian that support privacy regulations and enable interoperability across platforms.
- Keep the customer experience central: Relevance and respect earn long-term loyalty, values embedded in Experian’s approach to responsible marketing.
What does the future look like for advertising without cookies?
The end of cookies isn’t the end of personalization. It’s a chance to design advertising that earns consumer trust. Marketers who connect data responsibly and measure real outcomes will outperform those chasing outdated identifiers.
Experian already helps global brands build this future through:
- Consumer Sync identity solution: Enables consistent, privacy-safe engagement across channels.

FAQs
Cookie deprecation refers to browsers ending support for third-party cookies, which track users across sites. This shift promotes greater privacy and transparency while encouraging marketers to use first-party and identity-based data for targeting and measurement.
As of September 2025, Google paused its plan to fully deprecate third-party cookies in Chrome. The company will introduce new user privacy controls that allow individuals to choose how their data is shared, while continuing to test privacy-preserving APIs through its Privacy Sandbox.
Safari and Firefox already block third-party cookies, and other browsers have adopted similar restrictions. While Chrome’s deprecation is paused, its large user base, more than 60 percent of global traffic, means its future policies will continue to influence how marketers plan and measure campaigns.
Even with Google’s pause, marketers should keep building privacy-first strategies. Focus on:
– Strengthening first-party data through loyalty programs and preference centers.
– Using Experian’s Digital Graph to connect audiences across devices and environments.
– Activating with Consumer Sync® for consistent, privacy-safe engagement.
– Collaborating securely through Experian’s data collaboration solutions, which allow brands to share insights responsibly.

Four ways to use Digital Graph and Marketing Attributes When these two products come together, our clients have a 360-degree view of their consumers, which helps them power four critical use cases: Analytics and insights: Learn more about your consumers by connecting our Marketing Attributes with our Digital Graph's identifiers. For example, a retailer can discover that their recent customers over-index as pickleball fans and players, leading the retailer to sponsor a professional pickleball event. Inventory monetization: When supply-side partners know their audience better, they can attract advertisers in search of that audience. For example, a publisher might find out that their audience is full of pickleball fans, leading them to reach out to brands that want to reach this audience. Activation: Companies with access to more digital identifiers from our Digital Graph can reach more people, while controlling frequency across channels. A company might know that they want to reach pickleball fans. Now, they have the digital identifiers needed to reach pickleball fans across all digital channels where they consume content, leading to increased reach. Measurement and attribution: Use the Digital Graph’s support for various digital identifiers to understand all consumer touchpoints, from media impressions to conversions. Then, lean on our Marketing Attributes to determine who your messaging resonated with. For example, a company uses our Digital Graph to know if it was the same individual who was exposed to an ad on CTV and converted via e-commerce. On top of that, the company can use our Marketing Attributes data to find out that the people who purchased were overwhelmingly pickleball fans. Connect with us to learn more about how our Digital Graph and Marketing Attributes joint solution can provide the data and insights you need to create, activate, and measure cross-channel media campaigns.

With U.S. brands expected to invest over $28 billion in connected TV (CTV) in 2024, balancing linear TV and CTV is now a top priority. Advertisers need to integrate these platforms as the TV landscape evolves to reach audiences with various viewing habits. A successful strategy requires both linear and CTV approaches to effectively reach audiences at scale. We interviewed experts from Comcast Advertising, Disney, Fox, Samsung Ads, Snowflake, and others to gain insights on the evolving landscape of linear and CTV. In our video, they discuss audience fragmentation, data-driven targeting, measurement challenges, and more. Watch now to hear their perspectives. Five considerations for connecting with linear TV and CTV audiences 1. Adapt to audience fragmentation With consumers' rapid shift toward streaming, it's easy to overlook the enduring significance of linear TV, which still commands a large portion of viewership. According to Jamie Power of the Walt Disney Company, roughly half of the current ad supply remains linear, highlighting the need for brands to adapt their strategies to target traditional TV viewers and cord-cutters. As streaming continues to rise, ensuring your strategy integrates both CTV and linear TV is crucial for reaching the full spectrum of audiences. "I don't think that we thought the world would shift so quickly to streaming, but it's not always just all about streaming; there's still such a massive audience in linear."Jamie Power, Disney 2. Combine linear TV’s reach with CTV’s precision Blending the reach of linear TV with the granular targeting capabilities of CTV allows advertisers to engage both broad and niche audiences. Data is critical in understanding audience behavior across these platforms, enabling brands to create highly relevant campaigns tailored to specific audience segments. This strategic use of data enhances engagement and ensures that the right viewers see advertising campaigns. "The future of TV is really around managing the fragmentation of audiences and making sure that you can reach those audiences addressably wherever they're watching TV."Carmela Fournier, Comcast Advertising 3. Manage frequency across platforms Cross-platform campaigns require managing ad frequency to avoid oversaturation while ensuring adequate exposure. With a variety of offline and digital IDs resolved to consumers, our Digital and Offline Graphs can help maintain consistent messaging across linear TV and CTV. This approach allows advertisers to strike the right balance, preventing ad fatigue and delivering the right audience reach for campaign impact. "You've got to make sure that you're not reaching the same homes too many times, that you're reaching everybody the right amount of times."Justin Rosen, Ampersand 4. Focus on consistent measurement Linear TV and CTV offer different data granularities, necessitating tailored approaches for accurate cross-platform campaign measurement. Bridging these data gaps requires advanced tools that streamline reporting for both mediums. As the industry moves toward consistent measurement standards, advertisers must adopt solutions that provide a comprehensive view of campaign performance, enabling them to optimize their cross-platform efforts. "Where I think there are pitfalls are with the measurement piece, it's highly fragmented, there's more work to be done, we're not necessarily unified in terms of a consistent approach to measurement."April Weeks, Basis 5. Align with shifts in audience behavior The success of cross-platform campaigns hinges on staying agile and responsive to shifting audience preferences. As CTV adoption grows, advertisers must proactively adjust their strategies to align with how viewers engage across linear and streaming platforms. Ideas include: Regularly updating creative Adjusting the media mix Utilizing real-time data insights to ensure campaigns remain relevant "At Fox we were a traditional linear company, and essentially what we're trying to do is merge the reach and the scale of TV as well as the reach and the scale of all the cord-cutters and cord-nevers that Tubi possesses." Darren Sherriff – FoxDarren Sherriff, Fox As streaming TV rapidly changes, brands must stay ahead of trends and shifts in consumer behavior to tap into CTV's growing potential. By focusing on these opportunities, advertisers can blend linear TV and CTV, ensuring their campaigns reach audiences wherever they watch.
