Our digital world is more than ever characterised by switching between different devices – and often within just a few minutes. But how can companies successfully link user contacts across desktops, smartphones, tablets and even connected devices? This question is increasingly being discussed within the context of cross-device tracking, as simply looking at isolated touchpoints is no longer sufficient. To truly understand your target audience, you need to uncover and consistently capture all touchpoints in the customer journey.
Understanding and applying cross-device tracking
People constantly switch devices, and many do so quite naturally, without giving it a second thought. A typical user journey often begins on a smartphone, continues on a laptop, and might end with a purchasing decision in a smart home. Without well-thought-out cross-device tracking, a large part of this customer journey remains invisible. This distorts analysis because individual channels are incorrectly assessed, and marketing measures cannot be optimally coordinated.
Many companies report that they are urgently seeking impulses for the integration of such concepts. They often grapple with questions such as: „How do we efficiently evaluate our advertising budgets?“ or „Which channels are truly relevant for sales?“ Cross-device tracking provides new answers precisely here, as it makes it possible to identify users across different devices and analyse their behaviour holistically [1][3].
To achieve this, various technologies are available. For example, the deterministic method actively links unique identifiers – such as through logins or user IDs – together[3]. Probabilistic models, which work on the basis of behaviour patterns and AI, are also gaining importance because they can reliably assign anonymous users too[2][9]. Those who specifically rely on cross-device tracking benefit from more precise attribution models and avoid isolated solutions.
Practical examples: How companies benefit specifically
Imagine you want to buy a new camera. In the morning, you search for models on your smartphone, in the afternoon you compare prices on your tablet, and finally, you make the purchase on your desktop in the evening. Without cross-device tracking, you would appear as three different users, even though it's only one person [7]. Only targeted tracking provides the complete picture and helps to use advertising budgets effectively.
Another example: you're advertising for a gym, and your banner reaches users on their smartphones. However, they only click on it later on their laptops, after having watched a TV advert. Without cross-device analysis, it remains entirely unclear which touchpoint truly influenced the decision. Cross-device tracking provides transparency and shows where your efforts are effective [1].
In practice, this means that companies which design their sales channels, customer portals or learning platforms with a user-centric approach achieve measurably better results through cross-device tracking. They identify the most important conversion points, optimise their communication and can tailor retargeting. Numerous companies that involve iROI coaching in these matters report noticeable improvements in digital marketing.
BEST PRACTICE with one customer (name hidden due to NDA contract) A well-known electronics retail chain with over 100 branches implemented cross-device tracking to understand user journeys from online shop to in-store pickup. The company used a professional consent management system to meet data protection requirements and integrated various analysis tools. This enabled the retail chain to track not only browsing behaviour but also order processes, returns, and Click & Collect across multiple devices. The insights gained from the analysis led to more targeted online and offline campaigns, and a significant increase in conversion rates. Furthermore, inefficient channels were identified more quickly, and the marketing budget was adjusted accordingly.
Cross-device tracking also demonstrates its strengths in e-learning and further education. Learners use smartphones, tablets, and laptops equally to access course materials. Companies that consistently map this learning path can analyse learning progress, identify usage barriers, and specifically improve the user experience.
Successfully Implementing Cross-Device Tracking – Practical Tips
Many companies would like a practical introduction to cross-device tracking but are unsure how best to proceed. Often, there is a lack of a clear data strategy or uncertainties regarding data protection. Structured approaches and the involvement of experienced coaches, such as those offered by iROI Coaching, can help here.
A first step is the analysis of existing tools and processes. Are you already using web analytics software such as Google Analytics 4, which supports cross-device tracking? Do you have a Customer Data Platform (CDP) in place to combine data from various sources? The combination of first-party data, cross-device identifiers, and consent management solutions forms the basis for a sustainable tracking strategy[9].
Ensure you actively involve your target audience. You will only achieve high acceptance if users understand what data is being collected and what added value they gain from it. Transparency builds trust – and that increases the willingness to provide data.
Experiment with different attribution models and adapt them regularly. What works today may be different tomorrow because user behaviour is constantly changing. Companies that continuously learn and adapt their measurement models remain flexible.
Cross-device tracking only makes sense if you actively use the insights in your day-to-day marketing activities. Share the data you collect with your teams, train your employees, and rely on data-driven decisions. This allows you to specifically plan cross-media campaigns and reach your target audiences with pinpoint accuracy.
Cross-device tracking as a driver for your digital strategy
The importance of cross-device tracking will continue to grow as more devices are used in everyday life and customer expectations rise. Companies that invest now will secure a clear competitive advantage. They will gain insights into the true customer journey, optimise their channels and thus increase the success of their marketing measures[5].
Those who effectively use cross-device tracking can not only improve retargeting but also the entire customer experience. Simply put: those who know their users can support them better – no matter which device they are currently using. Let experts like iROI Coaching assist you with this, guiding you practically through the implementation of relevant projects.
My analysis
Cross-device tracking is no longer a niche topic, but a key success factor for companies that want to survive in a digitised world. It allows for an understanding of user interactions across all channels and devices, the traceability of the customer journey, and the efficient allocation of marketing budgets. The right technology, a clear data strategy, and the involvement of the target audience are crucial in fully exploiting its potential. Practical examples show that companies that embrace cross-device tracking early on can significantly increase their competitiveness. It is important to use flexible models and to regularly adapt to changing conditions. Support from experienced coaches, such as iROI Coaching, helps to take the right steps and secure sustainable success.
