1% User Testing: Google’s Gradual Elimination of Third-Party Cookies and Its Impact on Online Advertising!

In January, Google will launch a new feature that will affect 1% of randomly selected Chrome users worldwide. What it means to PPC services UK or in any other country.

In a recent announcement, Google unveiled plans to gradually eliminate third-party cookies, a fundamental component of digital advertising, as part of its wider Privacy Sandbox initiative. This strategic move by Google aims to strike a balance between user privacy and maintaining essential web functionalities reliant on disparate cookies. 

The phased approach is set to commence with a 1% user testing period in early 2024, followed by a more extensive phase-out scheduled for the third quarter. This article delves into the implications of Google’s decision and its impact on the landscape of online advertising.

Google Chrome has released an update that essentially removes third-party cookies for an estimated 30 million users. With a roughly 63% browser market share, Chrome’s impact on third-party cookie monitoring outperforms competitors such as Apple Safari and Mozilla Firefox, which had already removed such cookies by 2020.

Given that over 3 billion people use Google Chrome, according to AtlasVPN in 2021, the January 4th upgrade might harm a sizable user base. Following the upgrade, a randomly selected test pool of users will get messages on their desktop or Android Chrome browsers informing them that Tracking Protection has been activated.

“If a site encounters issues without third-party cookies, and Chrome detects repeated page refreshes, users will be prompted with an option to temporarily re-enable third-party cookies for that specific website,” Google explained. The eye symbol on the right side of the address bar will provide access to this choice.”

Understanding Third-Party Cookies

Third-party cookies have long been pivotal in digital advertising, enabling advertisers to track user behavior across diverse websites. This tracking facilitates the creation of detailed user profiles, allowing companies to customize advertising campaigns. However, this practice has raised considerable privacy concerns due to its intrusive monitoring of users’ online activities.

Despite their utility for advertisers, third-party cookies have faced increasing scrutiny for their potential to compromise user privacy. The extensive tracking enabled by these cookies has led to a growing unease among users about the collection and use of their personal data without explicit consent. This concern has fueled discussions around the ethical implications of targeted advertising and the need for more transparent and user-centric data practices.

As privacy regulations tighten globally, the reliance on third-party cookies has become a focal point of debate. Users are becoming more conscious of their digital footprint, and the demand for enhanced privacy measures is driving industry leaders, including Google, to reevaluate and reshape their approaches. The elimination of third-party cookies is not only a response to these concerns but also a proactive step towards fostering a more privacy-conscious digital ecosystem.

Google’s Phased Approach

To address potential web compatibility issues, Google is adopting a carefully phased approach to the elimination of third-party cookies. The initial 1% testing phase is designed to identify and rectify any problems, with the aim of minimizing disruptions to the user experience. During this phase, Google plans to implement temporary solutions and user controls in Chrome, ensuring efficient management of any disturbances.

This measured approach underscores Google’s commitment to a smooth transition and highlights its consideration of potential challenges that might arise from the elimination of third-party cookies. The 1% testing phase serves as a proactive measure, allowing Google to identify any unforeseen complications and promptly address them. 

The implementation of temporary solutions during this testing period showcases Google’s dedication to maintaining a seamless browsing experience for users. Additionally, the introduction of user controls within the Chrome browser emphasizes the company’s commitment to empowering users with the ability to manage disruptions and tailor their privacy preferences. By incorporating these strategic measures, Google aims not only to enhance user privacy but also to ensure a user-friendly and technically robust environment during this pivotal shift in the digital advertising landscape.

Future of Online Advertising

Post the phase-out of third-party cookies, advertisers are anticipated to transition to using Google’s Privacy Sandbox APIs. These APIs are designed to display ads based on a user’s computed interests, aligning with evolving privacy standards. It’s noteworthy that major competitors like Firefox and Safari have already defaulted to blocking third-party cookies.

The anticipated transition of advertisers to Google’s Privacy Sandbox APIs signifies a shift towards a more privacy-centric advertising ecosystem. These APIs are poised to revolutionize ad targeting by relying on a user’s computed interests rather than intrusive tracking through third-party cookies. 

This approach aligns with the evolving privacy standards and emphasizes Google’s commitment to delivering personalized content while respecting user privacy. The fact that major competitors like Firefox and Safari have already taken the initiative to default to blocking third-party cookies highlights the industry-wide recognition of the need for heightened user privacy. 

As the digital landscape adapts to these changes, the move towards Privacy Sandbox APIs represents a pivotal moment in the ongoing efforts to strike a balance between personalized advertising and safeguarding user data.

Google’s Commitment to User Privacy

Google’s recent announcement to eliminate third-party cookies is part of a comprehensive strategy to fortify user privacy. The introduction of the Privacy Sandbox further exemplifies Google’s dedication to creating a secure digital environment. This initiative offers a set of privacy-focused application programming interfaces (APIs) designed to enable personalized advertising without compromising user data. 

Additionally, Google has been proactive in testing an IP Protection feature, providing users with an extra layer of security. This feature allows users to shield their IP addresses through proxy servers, demonstrating Google’s commitment to minimizing the risks of covert online tracking. 

By implementing these multifaceted privacy measures, Google is not only responding to industry trends but also setting new standards for user-centric data protection in the ever-evolving digital landscape.


Google’s decision to eliminate third-party cookies marks a significant stride in fortifying user privacy. The phased approach underscores an effort to balance user privacy with the preservation of crucial web functionalities reliant on divergent cookies. 

As third-party cookies make their exit, advertisers are poised to shift towards Google’s Privacy Sandbox APIs, designed to cater to user interests while adhering to evolving privacy standards. 

Notably, major competitors have already taken steps to block third-party cookies by default. Google’s steadfast commitment to user privacy is commendable, and the impact of this move on the future of online advertising like in  PPC services UK or any other location remains a point of keen interest.
