7 Strategies to Build Your Audience in a Cookieless, GDPR-Compliant World (2025 and Beyond)
As we approach 2025, businesses face two transformative challenges in the digital marketing landscape: the continued enforcement of GDPR (General Data Protection Regulation) and the complete phase-out of third-party cookies. While these changes are critical for user privacy, they are also reshaping how companies collect and leverage data to build audiences. But these challenges offer an opportunity to create more ethical, transparent data management practices, ensuring that your business thrives while respecting user privacy.
In this article, we’ll explore 7 strategies for building your audience in a cookieless, GDPR-compliant world, setting your brand up for success in 2025 and beyond.
1. Focus on First-Party Data as Your Gold Standard
As the world moves toward a cookieless future, first-party data—information collected directly from your users—will become your most valuable asset. This includes data gathered through website interactions, user profiles, subscriptions, purchases, or app usage. Unlike third-party data, which is collected from external sources, first-party data is voluntarily provided by users, offering a higher degree of accuracy and trust.
Why it matters: First-party data is GDPR-compliant by design, as it involves direct user consent, reducing the risk of data privacy violations. This data not only helps businesses better understand customer behavior but also empowers you to offer personalized experiences without needing to rely on third-party cookies.
How to collect it:
Create opt-in forms that encourage users to share their preferences and subscribe to your communications.
Utilize customer preference centers, where users can manage their data and opt into different types of interactions.
Implement engagement tracking across your own digital properties, such as websites or apps, to capture valuable behavioral insights.
2. Prioritize Transparency and Explicit User Consent
GDPR compliance remains a cornerstone of audience-building in the modern digital world. The regulation places strict requirements on how companies collect, process, and store personal data, including the need for explicit consent from users before data collection. As we move towards a cookieless future, businesses must rethink how they collect and use customer data in a way that respects user privacy and provides clear information on data usage.
Why it matters: Transparency fosters trust. Users are more likely to share their data if they understand what it will be used for and feel secure in their privacy. Clear consent mechanisms also mitigate the risk of legal repercussions and fines for non-compliance.
How to stay compliant:
Use clear and granular consent banners that give users control over their data-sharing preferences.
Ensure data collection notices clearly explain the purpose of the data being collected and how it will be used, stored, and shared.
Make it easy for users to exercise their rights under GDPR, such as the ability to request data access, deletion, or updates.
3. Leverage Privacy-Focused Advertising Solutions
As third-party cookies phase out completely by 2025, marketers must adopt privacy-first advertising solutions that respect user consent while still allowing for effective audience targeting. Solutions like Google’s Privacy Sandbox and Apple’s App Tracking Transparency (ATT) are setting the stage for a future where targeted ads can still be effective without compromising privacy.
Why it matters: These privacy-centric solutions aim to replace the tracking abilities of third-party cookies with more ethical, privacy-conscious alternatives. Tools such as FLoC (Federated Learning of Cohorts) and Topics API will allow advertisers to target users based on interest clusters rather than personal data, ensuring compliance with GDPR.
How to adapt:
Stay updated with developments in the Privacy Sandbox and other privacy-focused tracking technologies.
Implement contextual advertising that delivers relevant content based on the context of the webpage rather than user history.
Embrace first-party audience data to improve ad relevance, targeting existing users who have opted in.
4. Double Down on Email Marketing and CRM
In a world without cookies, email marketing and Customer Relationship Management (CRM) will become more important than ever. Unlike cookie-based data tracking, email addresses and CRM data are collected directly from users who have willingly provided it, making it a prime source of first-party data. This data not only helps build meaningful relationships but also enables direct, personalized communication without relying on third-party tracking.
Why it matters: Email marketing, when done right, can be both GDPR-compliant and incredibly effective at building and maintaining an engaged audience. Since users have explicitly opted in to receive your messages, you are able to maintain regular, direct communication without relying on cookies.
How to grow your list:
Offer value-driven lead magnets, such as free content, exclusive discounts, or personalized recommendations, in exchange for users’ contact information.
Build trust by sending personalized, relevant content and respecting users’ preferences and privacy.
Make it simple for users to manage their subscriptions and communication preferences to stay compliant with GDPR.
5. Embrace Data Anonymization and Aggregation
As businesses face increasing scrutiny over how they handle data, anonymization and data aggregation offer powerful solutions for building audiences while protecting user privacy. By anonymizing user data, companies can gain valuable insights into user behavior and trends without exposing personal information, thereby adhering to GDPR standards.
Why it matters: Anonymized and aggregated data can still provide valuable insights into audience behavior, enabling businesses to deliver relevant experiences while minimizing privacy risks. Additionally, this approach is more GDPR-compliant since it ensures that data cannot be traced back to individual users.
How to implement:
Use data anonymization tools to remove personally identifiable information (PII) from collected data sets.
Aggregate user data to identify trends and patterns, rather than tracking individual user journeys.
Ensure third-party providers are also adhering to GDPR anonymization standards when they process or store your data.
6. Build Trust Through Ethical Data Partnerships
In a post-cookie, GDPR-compliant world, forging ethical data partnerships will be key to expanding your audience and reaching new markets. Partnerships with other brands, platforms, or data providers can allow you to access valuable audience segments, provided that the data-sharing is transparent and complies with privacy regulations.
Why it matters: Ethical partnerships help you build credibility and trust with your audience, while also giving you access to additional data that can enhance your marketing strategies. These partnerships should be built on clear agreements about how user data is shared, stored, and used, all within the bounds of GDPR.
How to proceed:
Ensure that your data-sharing agreements are transparent, ethical, and comply with GDPR.
Choose partners who share your commitment to privacy and user consent.
Look for co-branded campaigns or content collaborations that can expand your reach in a compliant, trust-building manner.
7. Invest in Contextual and Behavioral Targeting Without Cookies
As third-party cookies disappear, contextual and behavioral targeting will become more prominent. Contextual targeting allows you to serve relevant ads or content based on the specific content a user is consuming in real-time, rather than their past behavior or personal information. Behavioral targeting, on the other hand, focuses on how users interact with your site or app, allowing you to segment audiences based on their engagement.
Why it matters: Without cookies, advertisers will need to adjust their strategies to focus on real-time user intent and engagement rather than relying on stored historical data. This ensures you remain effective in targeting while respecting user privacy.
How to implement:
Use contextual advertising solutions that match ads to the content a user is currently engaging with, rather than their browsing history.
Build user profiles based on their actions and preferences while on your website or app, ensuring that you’re targeting users based on their direct interactions.
Experiment with predictive modeling and machine learning to understand audience behavior and intent, using first-party data.
Conclusion
As we move towards a cookieless world in 2025, GDPR compliance remains critical for businesses that want to maintain trust and build sustainable, engaged audiences. By focusing on first-party data, prioritizing transparency, and embracing privacy-centric solutions like the Privacy Sandbox, businesses can not only adapt to these changes but thrive in a more privacy-conscious world.
The future of audience-building will require a deeper focus on ethical data practices, but this will also offer new opportunities for businesses to connect with users in more meaningful, trust-based ways. Adapt now, and your brand will be well-positioned for success in this new era of digital privacy.
