5 models of attribution to measure digital ROI
5 attribution models to measure digital ROI
Understanding which marketing actions generate conversions is essential to optimize your digital campaigns. In Switzerland, with its multilingual specificities and complex customer journeys, can transform your strategic decisions.
Here is an overview of the 5 main attribution models to analyze your performance:
- Last Click Attribution: Simple to use, but limits the overall view by valuing only the last interaction.
- First Click Attribution: Ideal for measuring the impact of acquisition campaigns, but neglects subsequent steps.
- Linear Attribution: Distributes credit evenly among all touchpoints, providing a balanced view.
- Time Decay Attribution: Gives more importance to recent interactions, useful for long decision cycles.
- Data-Driven Attribution: Uses advanced algorithms to precisely analyze each interaction, but requires a high volume of data and technical resources.

Marketing Attribution & Contribution: How does it work? Complete tutorial
1. Last Click Attribution
The last click attribution model attributes full credit for a conversion to the last interaction a customer had before completing a purchase or action[5].
Ease of use
This model is appreciated for its simplicity. It is often the default setting on analytics platforms like Google Analytics, making it accessible to almost all businesses. It only requires data from the last interaction, simplifying its implementation[5].
Moreover, over 60% of marketers continue to use it as their primary model, despite its well-documented flaws[5]. Its intuitive operation and clarity largely explain this popularity.
Challenges in the Swiss market
However, in the Swiss context, where campaigns often have to juggle between multiple languages and channels, this model can seriously lack precision. It tends to downplay the importance of previous interactions, which can represent up to 80% of undervalued touchpoints[4]. This poses particular challenges for companies managing multilingual audiences and complex customer journeys.
When to use this model?
Last click attribution is particularly relevant for campaigns with short sales cycles, such as flash sales or direct response ads. It is also useful for evaluating the effectiveness of channels that generate final conversions, such as email marketing campaigns or social media ads[5]. However, it does not fully capture the richness of multichannel interactions.
Tips for better analysis
For a more comprehensive evaluation, it is recommended to combine this model with other attribution approaches. For example, comparing the results of the last click model with those of a linear or time decay attribution can provide a more nuanced view of marketing performance[6]. Additionally, regularly adjusting attribution parameters in your analytics tools ensures that your data remains aligned with your campaign goals and market specifics. This allows for more representative insights and optimization of your marketing efforts.
2. First Click Attribution
The first click attribution model works differently from the last click model. Here, 100% of the credit for a conversion is attributed to the very first interaction a user had with a brand or campaign, without considering the following touchpoints[2][3].
How it works
This model highlights the channel that initiated the first contact with the user. It attributes all credit to this single point. Its simplicity lies in the fact that many analytics platforms include this option by default, making its implementation quick and easy. However, in a , this model can show its limits.
Useful for acquisition campaigns
First click attribution is particularly valuable for measuring the effectiveness of campaigns aimed at increasing awareness and attracting new users. Take the example of a Geneva-based agency like : this model can be used to analyze a multilingual campaign targeting Swiss SMEs. If a user initially discovers a brand through a French display ad before converting later through a direct visit, the credit will be entirely attributed to this first interaction. This helps evaluate the impact of initial efforts to capture attention.
Limits in a Swiss context
In Switzerland, where consumers interact with brands through various channels and languages before converting, this model may lack nuance. It overlooks essential elements of the customer journey, such as nurturing, retargeting, or cross-device interactions. These omissions can lead to underestimating the importance of certain channels in the overall conversion process.
When and how to use it
First click attribution is ideal for specific goals, such as assessing brand awareness. However, it should not be used alone to analyze the ROI of complex campaigns. Like the last click model, it offers a partial view of the customer journey. A more balanced approach is to combine this model with other attribution methods. This provides a more comprehensive view, particularly useful for agencies looking to create personalized digital experiences tailored to a multilingual audience.
3. Linear Attribution
Linear attribution evenly distributes credit among all touchpoints that contributed to a conversion. For example, if a user interacts with four different channels before converting, each channel is assigned 25% of the credit for that conversion[2][3]. This reflects the idea that each interaction plays a role in the decision-making process.
A balanced approach for the customer journey
Unlike models that favor a single touchpoint, such as first or last click, linear attribution values each step of the customer journey. This approach is particularly relevant in a Swiss context, where consumers, often multilingual, use multiple channels before making a decision. This helps avoid biases and better understand the overall impact of multichannel campaigns.
A simple solution to implement
One of the great advantages of this model is its ease of implementation. Popular analytics tools, such as , include linear attribution as a standard feature. This makes it an ideal option for Swiss small and medium enterprises (SMEs), which may not always have access to advanced technical resources or data analysis specialists[2][3]. This accessibility makes it a practical choice for optimizing marketing campaigns without excessive complexity.
Perfect for nurturing campaigns
Linear attribution is particularly suitable for campaigns where each interaction plays a comparable role in guiding the user towards a conversion. It fits well in B2B strategies, longer sales cycles, or campaigns combining content marketing, nurturing emails, and retargeting[3][4]. In the multilingual Swiss digital context, it allows for a fair evaluation of campaign performance targeting different audience segments, whether local or international customers.
Limits to keep in mind
Despite its advantages, this model has weaknesses. By assigning equal weight to all interactions, it may undervalue the importance of certain critical touchpoints. Consequently, this could skew budget allocation decisions if some channels have a more significant impact than others[4][5].
Need for rigorous data tracking
To fully leverage linear attribution, detailed tracking of user interactions is essential. This includes data from various channels, such as paid advertising, emails, social media, and direct visits[3][4]. Swiss companies must also ensure compliance with the Federal Data Protection Act, use reliable analytics tools, and apply consistent UTM tagging to ensure the accuracy of collected data.
A well-suited solution for the Swiss market
In the Swiss digital landscape, linear attribution is particularly relevant for multilingual campaigns. It offers a fair assessment of channel performance in French, German, and Italian. Additionally, reports can integrate specific formats for the local market, such as the Swiss franc (CHF), to provide an analysis tailored to regional and linguistic realities. This neutral approach allows companies to better understand the dynamics of their campaigns in such a diverse environment.

4. Time Decay Attribution
Time decay attribution gives more weight to interactions that occur just before a conversion. This is based on the idea that recent touchpoints have a stronger influence on the purchase decision[3]. For example, if a user discovers a brand through a display ad, signs up for a newsletter, then clicks on a retargeting ad before making a purchase, that last interaction will be most valued.
A model aligned with consumer behavior
This model captures both the cumulative impact of multiple interactions and the increased role of recent touchpoints. It is particularly relevant for markets like Switzerland, where decision cycles are often longer, especially in areas like banking, insurance, or luxury products[7]. However, this requires rigorous technical tracking to accurately reflect these complex journeys.
Infrastructure and implementation
To fully leverage this model, a robust tracking infrastructure is essential. This must combine data from various sources like web analytics, CRMs, advertising platforms, and email marketing tools[3]. While this model demands precise timestamping of each user interaction, it is less complex than some data-driven analysis solutions. Additionally, tools like Google Analytics 4 integrate this feature, simplifying adoption for Swiss companies, regardless of their sector or size.
Ideal for sophisticated multichannel campaigns
This model is particularly suited for analyzing complex customer journeys, typical of the multilingual Swiss market. For instance, a financial company based in Geneva can assess the impact of late interactions on the final conversion[7]. This ability to identify the most effective channels towards the end of the journey helps optimize advertising budgets to maximize results.
