With the demand for online privacy on the rise, Google Chrome announced that in 2024 it will adopt plans to eliminate support for third-party cookies, changing the way the user experience is conducted to ensure more respect for their privacy.
Considering that the vast majority of advertisers use third-party cookies in their digital marketing strategies, it becomes crucial to take steps now to adapt to this new privacy-focused scenario. Continue reading the article to understand what this means and how you can prepare for these changes.
What is a cookie and why is it important?
"I agree to the use of cookies on this site." It's quite possible that this phrase is familiar, especially if you often browse the internet. The word "cookies" has become part of our daily digital vocabulary. However, despite their constant presence, not everyone understands exactly what they do or how they can be used to benefit a business.
So, let's get to the basics. What is a cookie? In the digital world, a cookie is a small file that websites place on your browser to collect data about your preferences and browsing. They monitor your activities so that websites can offer a more personalized and targeted experience.
In a practical example, imagine you show interest in shoes while browsing online. Cookies capture this interest, and then you start seeing more shoe-related content.
Types of cookies
Generally speaking, there are two types of cookies.
One type is primary cookies — also known as first-party cookies — stored by the website itself that the person accesses. These are cases of items left in a shopping cart or the selected language.
The second type is third-party cookies. In this case, the storage part is handled by a third-party organization, which acts on behalf of different companies, such as online advertisers.

End of Third-Party Cookies
Third-party cookies used to work for advertisers, collecting information about your browsing habits across various websites. It was a powerful tool for marketing, allowing for highly personalized ads that seemed to "read your mind."
Despite being useful tools for advertisers, third-party cookies began to worry many people. The idea of being constantly tracked and having one's data collected without clearly understanding by whom, or for what purpose, made many feel uncomfortable.
Furthermore, the possibility of building detailed user profiles without adequate transparency about what was being collected and how it would be used sparked debates about ethics and privacy on the internet. This concern for privacy led to calls for greater transparency and control over this data.
Google begins disabling Chrome extensions
Since last year, Google announced plans to disable support for third-party cookies in its Chrome browser. This decision is part of a larger initiative called "Privacy Sandbox," which aims to develop technologies that protect user privacy and provide advertisers with the necessary tools to run effective campaigns without compromising that privacy.
By disabling third-party cookies, Google seeks to align with users' privacy expectations and global regulations, such as GDPR in Europe and CCPA in California.

How will it work now?
With the elimination of third-party cookies, Google is proposing alternatives that still allow ad personalization and effectiveness measurement, but in a way that preserves user privacy. Some of these proposals include:
- FLoC (Federated Learning of Cohorts): This technology groups users with similar interests, without identifying individuals specifically. This way, advertisers can target their ads to groups of people, rather than individual users.
- Turtledove (Two Uncorrelated Requests, Then Locally-Executed Decision On Victory): This method proposes a way to conduct ad auctions and decide which ad to show directly on the user's device, without needing to collect individual data.
- Trust Tokens: An alternative to combat online fraud and confirm that a user is real without needing to identify them individually.
How does this impact my marketing strategy?
1. Targeted Advertising
The removal of third-party cookies makes it more difficult to precisely target ads based on users' browsing behavior across different websites.
Adaptation: Explore alternative targeting methods, such as using first-party data (information collected directly from your audience) and contextual targeting (based on the content the user is currently consuming). Additionally, closely monitor new technologies and standards proposed in Google's Privacy Sandbox.
2. Personalization
The personalization of content and offers based on users' browsing history on third-party sites will be limited.
Adaptation: Invest in building a direct relationship with your audience to collect first-party data. Use this information to personalize the experience on your website and in your communications. Techniques such as content marketing and email marketing become even more valuable.
3. Measurement and Analysis
The ability to track user behavior across multiple sites to measure campaign effectiveness will be affected.
Adaptation: Adopt tools and metrics that are less reliant on third-party cookies. Consider working with engagement metrics within your own site and using analytics platforms that respect user privacy. Additionally, keep an eye out for solutions that promise campaign measurement without compromising privacy.
4. Consent and Privacy
Growing privacy concerns mean users expect greater transparency and control over their data.
Adaptation: Be transparent about how you collect, use, and store user data. Offer clear options for users to manage their consent. This can help build trust and enhance your brand's reputation.
5. Customer Relationship
The change forces brands to rethink how they interact with their audience.
Adaptation: Focus on strategies that build a direct and meaningful relationship with your audience. Loyalty programs, high-quality content, and personalized interactions based on first-party data can strengthen customer loyalty.
Conclusion
While the elimination of third-party cookies represents a challenge, it also offers an opportunity to innovate and improve how you engage with your audience.
By adopting strategies focused on privacy, ethical data collection, and developing a genuine relationship with customers, your brand can stand out in an increasingly competitive market.
