Google adds another plot twist to its privacy announcements, saying it will not ultimately remove third-party cookies from Chrome as previously announced through the Privacy Sandbox initiative. This change responds to diverse industry reactions, including concerns from advertisers, developers, and regulators about the impact of completely removing these cookies on the digital ecosystem. From now on, internet users will be able to manage their privacy directly from their browser settings, instead of facing the pop-up prompts that traditionally appear to accept or reject cookies. "We have decided to maintain our current approach of offering users the option to opt out of third-party cookies in Chrome and will not be implementing a new, separate prompt for third-party cookies. Users can continue to choose the best option in Chrome's privacy and security settings," the official website states. As justification, they add that since announcing the Privacy Sandbox initiative in 2019, "new opportunities have emerged to protect and secure users' browsing experience with AI, and the global regulatory landscape has evolved considerably." What will happen next? (We don't know, but neither does Google.) The announcement that it will not eliminate third-party cookies generates a mixed reaction in the industry. On the one hand, those who rely on these cookies to personalize ads and measure campaign performance may see this as a partial victory. However, Google assures that the implementation of the Privacy Sandbox will continue, suggesting that third-party cookies will not disappear, but rather that their use will be optimized through new tools. As explained on the website, "The goal of the Privacy Sandbox initiative is to develop new ways to strengthen online privacy, while ensuring a sustainable, ad-supported internet (...) We will continue working with the ecosystem to determine how these technologies can best serve the industry and consumers." Google had already proposed some (failed) solutions for advertisers that were more privacy-friendly when collecting data from internet users. For example, APIs like FLoC (Federated Learning of Cohorts) and Turtledove allowed for advertising targeted to groups of users with similar interests, rather than specific individuals. It then introduced Topics, a targeted advertising system that was announced with great fanfare and never made it out of the testing phase. It also created a Noise Lab (which still exists) so developers could experiment with reports and fine-tune the measurement APIs to their specific needs. In that space, the company offers code samples to address key use cases. How it will affect advertisers Google's change of course regarding third-party cookies implies a transition to a more sophisticated privacy model, requiring advertisers to adapt to new forms of measurement and campaign personalization. Although they won't be completely eliminated, control over cookies will be more in the hands of users, who will be able to manage their preferences through Chrome's privacy settings. This doesn't mean that advertisers will lose the ability to create effective ads, but they will need to adopt the solutions proposed by Privacy Sandbox to continue personalizing their campaigns ethically and respectfully. News to come soon Google also said it will continue working on improving tracking protection in Chrome's Incognito mode, which already blocks third-party cookies by default. This includes IP Protection, which is scheduled to launch in the third quarter of 2025. "Additionally, we'll continue investing to make Chrome the world's most trusted browser, with technologies like Safe Browsing, Safe Checkup, built-in password protection, AI-powered security, and more," the company stated. They also announced that in the coming months they will be collecting feedback and recommendations through a shared and updated roadmap for these technologies, "including our future areas of investment."
