Howard Hubler The abandonment of third-party cookies has been one of the most significant transformations in digital marketing in recent years. Technology giants such as Google and Apple have consistently restricted the collection of user data, citing the need for increased privacy. As early as 2024, Google began phasing out third-party cookies in Chrome, directly affecting about 65% of global traffic. This development was a wake-up call for marketers who had spent decades building strategies based on users’ online behavior.
Third-party cookies have played a key role in retargeting, personalizing ads, and measuring campaign performance. Without this data, advertisers face an opaque user journey and diminished ROI. This is especially acute for brands that depend on programmatic advertising and automated platforms with an auction-based buying model.
In response to the disappearance of cookies, the market has begun to look for alternative ways to collect and process information. One of the most popular approaches is to strengthen the first-party data strategy, i.e. using data collected directly from company websites and applications. This includes registrations, surveys, subscriptions, purchase history, and site behavior. This approach requires a high level of trust on the part of users, which means that brands are increasingly focusing on creating value for the data provided: personalized offers, access to exclusive content, and loyalty programs.
Technological solutions are also actively developing. For example, Google offers Privacy Sandbox – a set of APIs that allow targeting users without disclosing their individual data. One of the key initiatives is Topics API technology, which replaces cookies with group categorization of interests formed on the device. However, the effectiveness of these solutions is still questionable, especially in terms of accuracy and scalability.
Another trend has been login-based identifiers – so-called unified IDs. Companies, such as The Trade Desk, offer to use unified anonymous IDs received after user authorization, for example, by email. This solution is promising, but its coverage is limited: not every user is ready to authorize when visiting a site.
Contextual advertising, once considered obsolete, has been given a second wind. Thanks to AI and NLP systems, advertising algorithms can analyze the content of pages in real time and show relevant ads without having to track the behavior of a particular user.
Changes are affecting the legal sphere as well. Marketers have to take into account the increasingly stringent requirements of data protection laws – GDPR in the EU, CCPA in California, and a similar law coming into force in Brazil from 2025. Companies that fail to comply with the new standards risk not only losing the trust of their audience, but also facing heavy fines.
In the cookie-free environment, the winners are those who can adapt flexibly, build transparent relationships with users and invest in long-term strategies – whether it’s developing their own platforms, creating value propositions in exchange for data, or moving to a more ethical audience engagement model. The end of cookies is not the demise of marketing, but the beginning of a new era where data becomes the result of trust, not surveillance.
