Third-party cookies, those small files stored on your devices as you browse the internet, play a key role in analyzing your online behavior. They make it possible to know which sites you visited, what purchases you made, and which ads you clicked on. This data allows websites to serve you personalized ads and improve your digital experience.
However, they raise concerns about privacy and security. They can, for example, be exploited for malicious activities, leading to personal data theft and exposure to harmful content. They also tend to slow down your browsing and unnecessarily consume your bandwidth.
Out of respect for privacy, many stakeholders, including regulators, consumers, and browser developers, are taking action against the use of third-party cookies. Laws such as the GDPR in Europe have been put in place, browsers like Safari and Firefox offer built-in blocking features, and Google has been planning to phase them out by 2024.
But what will the impact of this removal be on the digital ecosystem? How will it affect digital marketing and consumers, and what alternatives will emerge to keep the web thriving? This article explores these questions by detailing the stakes of the announced disappearance of third-party cookies.
Understanding the Announced End of Third-Party Cookies
The Decision by Tech Giants and Its Foundations
The end of third-party cookies is primarily driven by the decision of Google, the tech giant behind Chrome, the world's most widely used browser. Google announced in 2020 that it would remove third-party cookies from its browser by 2024. This decision is part of the Privacy Sandbox initiative, a project aimed at providing alternatives to third-party cookies that protect user privacy while preserving the web's advertising ecosystem.
Google is not the only web player pushing to end third-party cookies. Other browsers, such as Safari and Firefox, have already blocked them by default for several years. These browsers operate on the principle of privacy by design, which involves embedding personal data protection into digital products and services from the ground up.
The end of third-party cookies also responds to growing demand from internet users, who are increasingly concerned about their online privacy. According to an IFOP study, 83% of French people say they are worried about the protection of their personal data online. In addition, third-party cookies are subject to increasingly strict regulation, particularly under the General Data Protection Regulation (GDPR) in Europe, which requires explicit user consent for the placement and use of third-party cookies.
The Consequences for Online User Tracking
The end of third-party cookies will have major consequences for advertisers and agencies that rely on tracking users across the web. Third-party cookies make it possible to collect data on internet users' behavior across different websites and use it to serve them targeted ads based on their interests, needs, or purchase intent. This type of advertising, known as behavioral advertising, accounts for a significant share of the online advertising market, estimated at 86% in France in 2020. This tracking also enables retargeting in paid search and paid social, such as on Meta.

Without third-party cookies, it will be harder for advertisers and publishers to track users online and measure the effectiveness of their ad campaigns. They will need to find other ways to target their audiences, personalize their content, and analyze their performance. Some web players, like Google, are already proposing alternative solutions to third-party cookies based on privacy-friendlier technologies, such as FLoC cohorts or Privacy Sandbox APIs. However, these solutions face criticism and questions regarding their transparency, fairness, and GDPR compliance.

The Ripple Effects on the Digital Marketing Industry
Challenges for Ad Targeting and Personalization
The planned disappearance of third-party cookies is a turning point for the digital marketing industry, which has long relied on ad targeting and personalization. Without these trackers, advertisers face difficulties segmenting their audiences, delivering tailored ads, and keeping their customers' attention. Publishers also find it harder to monetize content and sell their ad inventory, directly impacting their partnerships with advertisers. According to IAB Europe, this situation could generate a revenue drop of up to 70% for publishers.
Alternative Strategies
In response to these challenges, digital marketing must pivot and adopt alternative strategies. These include:
- Universal identifiers, based on data such as email addresses or phone numbers. They make it possible to track users across the web while honoring their consent. Projects such as Unified ID 2.0 or LiveRamp IdentityLink are working to standardize these identifiers.
- Artificial intelligence, which analyzes user behavior and anticipates intent to deliver more personalized experiences. It also helps optimize ad campaigns, evaluate their effectiveness, and improve return on investment. Platforms like Google Marketing Platform and Salesforce Marketing Cloud have integrated AI into their solutions.
- Content marketing, which focuses on creating and distributing valuable, engaging, and relevant content with the goal of educating, entertaining, or persuading an audience. This builds brand awareness, trust, and loyalty while driving traffic and conversions. Tools like Wrike or HubSpot support the creation and management of this content.
The Rise of First-Party Data and User Consent
With the removal of third-party cookies, we are also seeing a surge in first-party data, collected directly by companies from their own audiences. This data, gathered with users' consent, is inherently more accurate, reliable, and privacy-respecting than third-party data. It opens the door to a deeper understanding of user needs and the ability to deliver truly personalized experiences. To collect and manage this information, professionals need the right tools, such as CRMs, DMPs, or CDPs. There are also many tools that allow you to collect, transfer, and visualize first-party data within a single platform to simplify analysis. Supermetrics is one such tool, and we have dedicated an entire article to it that you can check out.
The Impact on Consumer Privacy and the Regulatory Landscape
Stronger Privacy Protection
The upcoming disappearance of third-party cookies will significantly strengthen the protection of consumer privacy, a growing concern for internet users. Third-party cookies are often seen as an invasion of user privacy, as users frequently have no idea who is collecting their data, for what purpose, or what risks they face. An IFOP study reveals that 83% of French people express concerns about the security of their personal data online. Without these cookies, users will have greater control over their personal information and enjoy a faster, more secure browsing experience.
Compatibility with GDPR and Other Regulatory Frameworks
Eliminating third-party cookies will also greatly simplify compliance with the GDPR and other regulatory frameworks designed to protect personal data. Enforced since 2018, the GDPR requires explicit user authorization for the use of third-party cookies and mandates adherence to principles such as data minimization, transparency, and accountability. Other jurisdictions are following suit, with laws such as the CCPA in California, the LGPD in Brazil, and the PDPB in India. Without third-party cookies, online businesses will no longer need to manage user consent collection or navigate the various applicable regulations.
The Growing Role of Consumers in Managing Personal Data
With the end of third-party cookies, the importance of consumers' role in managing their personal data is also growing. They will have greater control over how their data is used. They will be able to express their preferences and requirements, and demand more value and quality in exchange for their information, choosing companies that offer personalized, useful, and privacy-respecting experiences. Consumers thus become active, engaged participants in protecting their own personal data and that of other users.
Conclusion
The announced obsolescence of third-party cookies represents a major revolution for the web. It will profoundly shape the digital marketing industry, affect user privacy protection, and reshape the regulatory landscape. Faced with these changes, professionals must adapt and explore viable alternatives to continue delivering tailored user experiences while preserving privacy.
It is essential that consumers become aware of their rights and responsibilities when it comes to personal data security. They must demand greater transparency and reciprocity from online businesses. This transformation represents an opportunity to build a more ethical, sustainable, and human-centered internet.
