From last-click to data-driven attribution

While an online conversion path used to consist of a single channel, it’s now a synthesis of multiple channels and interactions before the customer makes a purchase or before a lead is generated. This makes it more difficult for online marketers to explain the role of one specific advertisement or a specific channel in the customer journey. But Google Analytics 4 developed a solution for this: the data-driven attribution model.

Insight through attribution

First things first. We just mentioned the term ‘attribution’, but what exactly is that? Attribution is the process of assigning credit to every touchpoint during the customer journey, that contributed to conversion. You can find the attribution of marketing channels in Google Analytics and it’s also addressed when measuring and optimizing media expenditures across various channels. The attribution model on the other hand, can be a rule, a set of rules or a data-driven algorithm that determines how conversion credit is assigned to channels in the customer journey.

Since the customer journey now consists of more interactions and so becomes increasingly complex, the existing attribution models which use fixed rules fail to provide advertisers with enough information. Google responds to this in a smart way and introduces the cross-channel data-driven attribution model. After January 26, 2022, Google even automatically upgrades the attribution settings for Google Analytics 4 properties to this new attribution model. What does this new attribution model involve and what does it mean for the attribution of data collected in Google Analytics? We’re here to explain!

From last-click to data-driven

Google analytics previously used the last-click model as its standard attribution model. With the exception of direct traffic, the last channel which a visitor used to visit the website before converting, was assigned 100% of the conversion credit.

An example
Somebody clicks on a Google Search advertisement and visits the website. A day later this person sees a Facebook Ad of the same website. The person clicks on the Facebook Ad and goes on to make a purchase. The conversion path then consist of Paid Search > Facebook Paid Ads. Still, the conversion credit is 100% assigned to the last channel, Facebook Paid Ads. While the first channel, the Paid Search, definitely played a part in this conversion.

What is the data-driven attribution model?

The data-driven attribution model is based on machine learning. The algorithms assess both the converting and the non-converting paths. The model assigns credit to conversions based on how people search for your website or how they interact with search advertisements. Google’s algorithmic model can go far: up to 50 clicks and touchpoints.

The algorithm regulates itself and learns how the different touchpoints influence the conversion results. The model also takes into account factors, such as time since conversion, device type, number of interactions with advertisements and the sequence in which the advertisements are displayed. By means of counter-factual scenarios (if this, then that) the model evaluates what has happened versus what might have happened. In this way, the model determines which touchpoints have the highest probability of generating conversions. Based on this probability, the attribution model assigns conversion credit to the touchpoints.

The data-driven attribution method consists of two main components. The first part analyses the available customer journey data in order to develop conversion rate models for every conversion event. The second part uses predictions of conversion probability as input for an algorithm that assigns conversion credit to interactions with advertisements.

Where do I find the attribution settings?

If you’re already using Google Analytics 4, you’ll find the data-driven attribution model in several different places. You don’t have to set anything for this. Under the ‘Advertising Workspace’ heading, you can use the ‘Model comparison’ and ‘Conversion paths’ reports to see how the data-driven attribution model assigns conversion credit to every channel. These reports also let you to compare the last-click attribution model to the data-driven attribution model. Make sure to set only one conversion event as your goal.

By adjusting the Reporting attribution model to Data-driven in the ‘Attribution Settings’ on property level, you’ll also be able to find the attribution in the Conversion report, as well as in your Explore environment.

New Story is thrilled

The last-click attribution model often made online marketers fixate on attribution per channel. And so the introduction of the data-driven attribution model comes at just the right time. We’re super happy about that. Because of the data-driven attribution model, our online marketing specialists get a clear view of the impact of all online channels (and the respective campaigns) in the customer journey.
