Goodbye Cookie – Hello Future?

What should be a matter of course in brick-and-mortar retail, namely recognising regular customers and providing them with personalised advice, is becoming increasingly challenging in the digital world. While local booksellers can still recognise their customers by sight, digital business models are losing their most important tool with the demise of third-party cookies: cross-user tracking. This is a paradigm shift with far-reaching consequences, but also new opportunities.

A paradigm shift with consequences

But why is the end of third-party cookies so drastic? For years, they formed the foundation for targeted advertising, reach control and performance measurement in digital advertising. However, technological restrictions, regulatory requirements and increased awareness of data protection are making this practice obsolete. They are being replaced by new approaches, some tried and tested, some still in development, which are paving the way for a data-sovereign ecosystem.

A recent white paper by the German Digital Economy Association (BVDW) analyses this change along the following phases of media planning, which show how new technologies are closing existing gaps while opening up opportunities for more sustainable strategies:

Awareness phase: Relevance without tracking

Whereas third-party cookies used to be responsible for reach and target group segmentation, contextual targeting, privacy-preserving APIs (e.g. Topics API) and alternative identifiers now perform these tasks. This new approach requires more precise target group definitions and intelligent frequency control, but also promises greater relevance and less redundant advertising for users.

Consideration & Conversion: New ways to re-engage

Traditional retargeting is becoming less effective. Instead, data clean rooms and first-party data strategies are gaining importance. Protected data rooms make it possible to continue targeting specific audiences based on proprietary data and secure matching technologies – albeit under new technical and organisational conditions.

Optimization: Measurability reimagined

Without third-party cookies, traditional models such as conversion-based or frequency-based bidding lose accuracy. However, new approaches such as probabilistic frequency management and attribution based on first-party data show that effective campaign management remains possible if the data base is of high quality and systematically structured.

Solutions that address existing challenges in a more targeted manner have long been part of everyday life and are key drivers of the transformation of the ecosystem.

Challenge meets innovation potential

The elimination of cookies does not mean the end of targeted advertising, but it does mean the end of a dominant yet unsustainable standard. The future belongs to an advertising world that relies on first-hand data, interoperability and sovereignty over one’s own data. The ability to strategically combine new technologies while complying with data protection regulations will be crucial.

The BVDW white paper makes it clear that there are already numerous alternatives available – from identity solutions and context-based procedures to comprehensive industry standards. The key lies in the intelligent and well-thought-out integration of these approaches.

Thomas Peruzzi, spokesperson of the management board at Virtual Minds and head of the P3PC lab of the Working Group Data Tech & Economy at BVDW, adds: “A lot has happened since we first used an alternative identifier consistently in the programmatic advertising chain in 2019. Cookies are becoming increasingly less important. Solutions that address existing challenges in a more targeted manner have long been part of everyday life and are key drivers of the transformation of the ecosystem. Instead of continuing to refer to them as “alternative IDs” or extensions, we should recognise that they are becoming the new standard.”

Active instead of reactive: strategies for the transition

Saying goodbye to third-party cookies is no longer a vision of the future, but already a reality. Companies waiting for a single perfect solution risk losing reach, relevance and efficiency. A forward-looking switch to data protection-compliant alternatives, such as the targeted expansion of proprietary data, the use of alternative identification methods or the deployment of context-based procedures, creates independence from platforms and provides clear competitive advantages.

Those who invest now in data infrastructure, interoperable systems and transparent user relationships will secure digital sovereignty and sustainable campaign impact in an increasingly fragmented media landscape.
