From cookie dependence to customer trust: How B2B marketers are navigating the privacy-first era

As digital footprints continue to shape business strategies, today’s marketers face unprecedented challenges in balancing personalisation with privacy. 

With regulatory frameworks evolving rapidly, enforcement becoming stricter, and user awareness on the rise, the digital advertising landscape must rethink how data is collected and used.

In this blog, we look at how marketers are building direct relationships with customers based on value and trust, and finding ways to thrive in the new era of heightened GDPR compliance and calls for cookie-less marketing.

GDPR: The dawn of a new age of privacy

Over recent years, key developments in data privacy and compliance have added substantial pressure to the role of digital marketers. It all began in 2018 with the implementation of the General Data Protection Regulation (GDPR) – the EU’s landmark legislation governing organisations’ use of personal data.  

In a flurry of publicity and compliance, issues of privacy and data retention soon became top of mind. and US states followed suit with their own broad equivalents to GDPR, such as the California Consumer Privacy Act (CCPA), which went online in 2020. 

The UK enacted its own version of GDPR. In due course, well known search engines Mozilla, Firefox and Safari all chose to ban third party cookies due to the technology’s tracking of users’ online activities.  

What would Google do?

Naturally, everyone was waiting to see how Google, the tech giant with 90% of the world’s search market, would respond. At first, it seemed to be signalling an intention to phase out third-party cookies. It delayed its planned phase out, until July last year, when Anthony Chavez, VP of Google’s Privacy Sandbox initiative, announced that Google had decided to retain third-party cookies after all. In April of this year, that position became official, as Chavez said the company will, “maintain our current approach to offering users third-party cookie choice in Chrome.” 

For around 30 years, third-party cookies have been a cornerstone of digital marketing, enabling detailed user tracking, personalised advertising and performance measurement. But with GDPR and CCPA regulations now in force – and with hefty fines being handed out to organisations deemed to have overstepped the mark – the days of third-party cookies had appeared to be numbered. 

Google had long maintained that its third-party cookie alternative – the Privacy Sandbox – would enhance user privacy while preserving advertising effectiveness. Now it seems that the Privacy Sandbox experiment is all but over. So, does that mean third-party cookies will continue to rule digital marketer’s assumptions? Is the privacy revolution over? Perhaps not. 

Is the shift towards cookie-less marketing already underway?

We are now operating in a world where users are increasingly opting-out of online tracking

We are also operating in a stricter regulatory environment where businesses can be fined millions for breaching GDPR rules. 

So, the reaction from marketers to Google’s retention of third-party cookies may not be as significant as first assumed. 

The rise of privacy-first solutions

There are signs of a shift to a cookie-less future. Major brands are increasingly adopting first-party data strategies, building direct relationships with their customers through loyalty programmes, newsletters and authenticated experiences. 

In B2B, many marketers are already operating without third-party cookies. This transition has sparked innovative ways of maintaining targeting effectiveness while respecting privacy. First-party data collection, enabled by consent management, has become the new gold standard. And contextual advertising – targeting based on content rather than user behaviour – has seen a remarkable resurgence.  

Building direct relationships with customers and boosting trust through transparent data collection and usage policies have become paramount. Companies are also leveraging Customer Data Platforms (CDPs) to unify their first-party data and create comprehensive customer profiles without relying on third-party cookies. 

Likewise, machine learning technologies such as federated learning and collaborative software like data clean rooms allow organisations to collaborate and analyse user behaviour patterns while keeping personal data anonymous and secure. 

Preparing for a privacy-centric, cookie-less future

As we look ahead, several key strategies are emerging for marketing teams: 

  1. Building better systems to collect and understand data directly from your own customers  
  2. Creating clear, fair exchanges where customers willingly share their data in return for genuine value  
  3. Using new privacy-preserving technologies that can measure marketing success 
  4. Developing stronger, more personal relationships with customers through account-based marketing (ABM), rather than treating them as data points  
  5. Keeping up to date with changing privacy rules and new technology to stay ahead of the curve

Our verdict

While Google’s decision to retain third-party cookies might have slowed the privacy revolution, the main direction of travel remains clear. The EU and UK’s strict GDPR frameworks have set high global standards for data privacy, influencing how businesses worldwide approach data collection and usage. This isn’t just about compliance, it’s increasingly central to how B2B marketing operates. 

Looking ahead, successful B2B marketers will be those who embrace this future; seeing privacy-first not as a limitation but as an opportunity to build stronger, more trust-based customer relationships. The focus is shifting from tracking to trust, from data collection to data respect.
