The shift away from third-party cookies has been discussed for years, but it is now firmly underway. Privacy expectations have changed, regulations have tightened, and major platforms are reshaping how data can be collected and used.
For marketers, this marks a fundamental change. Strategies that once relied heavily on third-party tracking are becoming less effective, while businesses with strong first-party data foundations are gaining an advantage.
Understanding what this means and how to adapt is essential for staying competitive in a cookieless world.
What is actually happening to cookies?
Third-party cookies are not disappearing overnight, but their role is being significantly reduced.
Google has begun phasing out third-party cookies in Chrome as part of its Privacy Sandbox initiative, following years of restrictions already implemented by browsers such as Safari and Firefox. Chrome remains the world’s most widely used browser, making this shift particularly impactful.
At the same time, data protection regulations such as GDPR and similar frameworks globally have raised the bar for transparency and consent. Consumers are more aware of how their data is used and more selective about what they share.
Despite this, personalisation still matters. Statista reports that a strong majority of consumers expect personalised experiences, provided their data is handled responsibly.
This creates a clear tension between privacy and relevance, one that first-party data helps resolve.
Understanding the different types of customer data
To adapt effectively, marketers need clarity on how different data types fit into a modern strategy.
First-party data
Collected directly from your audience through your own platforms and interactions. This is the most valuable and reliable data type, provided it is collected transparently and stored securely.
Second-party data
Shared by trusted partners, often through direct data-sharing agreements. While not collected firsthand, it can be useful when aligned carefully with your own data strategy.
Zero-party data
Information that customers intentionally and proactively share, such as preferences, intentions, and feedback. This data is highly accurate and increasingly important as consumers expect greater control over how their data is used.
Forbes highlights zero-party data as a growing priority for brands looking to balance personalisation with privacy.
Compliance and trust are not optional
Collecting first-party data comes with responsibility.
Businesses must clearly communicate what data is being collected, why it is needed, and how it will be used. Privacy policies, consent mechanisms, and data security are no longer box-ticking exercises. They are central to brand trust.
PwC notes that organisations that handle customer data transparently are more likely to retain trust and long-term loyalty.
Trust is quickly becoming a competitive differentiator.
Preparing your marketing for a cookieless world
The move toward a cookieless future does not mean the end of effective targeting or measurement. It requires a shift in thinking.
Successful businesses are investing in stronger owned channels, improving data quality, integrating analytics platforms, and aligning marketing and CRM systems. They are also focusing more on contextual targeting, content relevance, and long-term audience relationships.
Gartner identifies first-party data strategy as a core pillar of modern digital marketing maturity.
This approach builds resilience as platforms, policies, and technologies continue to change.

The cookieless future is not a threat to businesses that adapt early. It is an opportunity to build stronger, more transparent relationships with customers.
