Is Your Marketing ROI Disappearing in 2025?

In recent years our digital marketing landscape has undergone a seismic shift, rendering traditional tracking methods increasingly obsolete. In the time of Universal Analytics this was still a relatively straightforward process, but understanding user behavior and campaign performance is these days a complex and often frustrating struggle. Several converging factors have fundamentally altered the effectiveness of standard tracking, creating the need for more sophisticated and adaptable solutions.

The much-discussed “cookie apocalypse” is no longer a threat in the distance. After 30-years of loyal service, we now face the effects of the depreciation of third-party cookies. Although Google Chrome’s full deprecation has faced some delays, other browsers like Safari and Firefox absolutely did not. The impact will vary from website to website, but we can say one thing for certain: the third-party cookie depreciation effectively makes a significant portion of your clients user-data vanish into thin air.

Third-party cookies, for years the backbone of cross-site tracking, allowed marketers to follow users across the web, building detailed profiles for targeted advertising and attribution. Their depreciation means that agencies relying on these methods are experiencing a dramatic loss of visibility into campaign effectiveness, hindering their ability to accurately measure ROI, ROAS and optimize their campaign strategies.

The move towards enhanced user privacy by browsers isn’t solely driven by regulatory changes, where we at Voxxy believe that these browsers more and more listen to their users in the ongoing “privacy-trend”. They have become increasingly proactive in safeguarding user data. With Safari’s Intelligent Tracking Prevention (ITP) as a prime example of this trend.

ITP goes beyond simply blocking third-party cookies. Although once considered as a reliable alternative, it limits the lifespan and effectiveness of even first-party cookies to a maximum of 7 days. This means that even the data collected directly from your clients website, is becoming less persistent and less comprehensive. Other browsers are following with similar privacy-enhancing features, creating a fragmented and challenging tracking environment for marketers and the agencies they work for.

The ability to effectively measure Personally Identifiable Information (PII) through first-party data has become of the utmost importance for campaign optimization. In our new cookieless landscape, these so-called “Enhanced Conversions” not only help to bridge the data gap for conversion tracking, but also provide platforms (like Google, Meta and Microsoft) with the ability to link conversions to user-interactions. Before sending the measured first-party PII-data to their own databases, the data is hashed in a privacy safe way (usually the SHA256 one-way algorithm). After collecting the hashed PII data, behind-the-scenes they will try to match this data to their user accounts, where it is used for audience building through features like Customer Match and conversion-based customer lists, enabling more effective targeting and campaign optimization.

The culmination of these changes – the disappearance of third-party cookies, smarter browser privacy features, the complexities of consent management, and first-party PII-collection – is having a tangible and often dramatic impact on campaign performance. Marketing agencies are witnessing a decline in their ability to accurately attribute conversions, personalize customer experiences, and optimize their marketing spend.

We often hear the nostalgic whisper that tracking website activity and data used to be a quick and simple task. This sentiment, while perhaps echoing the relative straightforwardness of Google’s “Legacy Tagging era”, now feels like a distant memory. The digital landscape has changed like never before, today’s reality demands a deep, almost forensic understanding of its evolving complexities.

Simply slapping a few tags onto a website won’t cut it anymore. Just like today’s modern cars, with their complex engines, require specialized maintenance by expert mechanics, your tracking infrastructure, the very engine of your marketing optimization, nowadays need expert attention to navigate the complex terrain of today’s digital environment.

Ignoring these profound changes in the tracking landscape is no longer a minor oversight; it’s asking yourself to drive a high-performance vehicle with a perpetually foggy windshield – you’re operating blindly, your vision obscured, and you’re inevitably risking a significant crash in your campaign performance, and ultimately your client’s ROI.

The days of “set-it-and-forget-it” tracking setups are behind us. We’ve entered a time where precision, expertise, and a proactive approach are not just advantages, but absolute necessities for survival and success.

Our digital marketing terrain has become a complex labyrinth, and only those equipped with the right knowledge can navigate it effectively and deliver tangible results.

In today’s digital landscape, inaccurate or incomplete tracking is a significant drain on your resources and your clients’ budgets. Wasted ad spend, flawed optimization decisions, and an inability to accurately measure ROI can lead to lost clients and missed opportunities.

After hundreds of successful implementations our tracking team at Voxxy is equipped with the deep and technical understanding that’s required to navigate the complexities of modern tracking effectively and efficiently. This leaves the road for you to focus on the core marketing functions.
