A Practical Guide To Multi-Touch Attribution

Posted by

The client journey includes multiple interactions in between the consumer and the merchant or provider.

We call each interaction in the client journey a touch point.

According to Salesforce.com, it takes, typically, 6 to 8 touches to produce a lead in the B2B space.

The number of touchpoints is even higher for a customer purchase.

Multi-touch attribution is the mechanism to evaluate each touch point’s contribution towards conversion and offers the appropriate credits to every touch point associated with the client journey.

Performing a multi-touch attribution analysis can assist online marketers comprehend the consumer journey and identify opportunities to further enhance the conversion paths.

In this short article, you will discover the essentials of multi-touch attribution, and the steps of carrying out multi-touch attribution analysis with easily accessible tools.

What To Consider Prior To Performing Multi-Touch Attribution Analysis

Define The Business Goal

What do you wish to accomplish from the multi-touch attribution analysis?

Do you wish to examine the roi (ROI) of a specific marketing channel, comprehend your consumer’s journey, or recognize important pages on your site for A/B testing?

Different business objectives might require various attribution analysis techniques.

Defining what you wish to accomplish from the beginning assists you get the results quicker.

Specify Conversion

Conversion is the wanted action you want your customers to take.

For ecommerce websites, it’s normally purchasing, defined by the order conclusion event.

For other industries, it may be an account sign-up or a subscription.

Different types of conversion likely have different conversion courses.

If you wish to carry out multi-touch attribution on several desired actions, I would suggest separating them into different analyses to avoid confusion.

Define Touch Point

Touch point might be any interaction in between your brand and your customers.

If this is your very first time running a multi-touch attribution analysis, I would recommend specifying it as a visit to your site from a particular marketing channel. Channel-based attribution is simple to carry out, and it might provide you an introduction of the customer journey.

If you want to comprehend how your clients engage with your site, I would advise specifying touchpoints based on pageviews on your site.

If you want to consist of interactions beyond the site, such as mobile app setup, e-mail open, or social engagement, you can integrate those events in your touch point definition, as long as you have the information.

No matter your touch point definition, the attribution system is the exact same. The more granular the touch points are defined, the more in-depth the attribution analysis is.

In this guide, we’ll focus on channel-based and pageview-based attribution.

You’ll discover how to use Google Analytics and another open-source tool to carry out those attribution analyses.

An Introduction To Multi-Touch Attribution Models

The methods of crediting touch points for their contributions to conversion are called attribution models.

The easiest attribution design is to offer all the credit to either the very first touch point, for bringing in the client at first, or the last touch point, for driving the conversion.

These 2 designs are called the first-touch attribution design and the last-touch attribution design, respectively.

Clearly, neither the first-touch nor the last-touch attribution model is “fair” to the remainder of the touch points.

Then, how about designating credit uniformly across all touch points associated with transforming a customer? That sounds affordable– and this is exactly how the direct attribution design works.

Nevertheless, allocating credit equally across all touch points assumes the touch points are equally essential, which does not seem “fair”, either.

Some argue the touch points near completion of the conversion paths are more crucial, while others favor the opposite. As an outcome, we have the position-based attribution design that allows online marketers to offer various weights to touchpoints based upon their areas in the conversion paths.

All the designs discussed above are under the classification of heuristic, or rule-based, attribution designs.

In addition to heuristic designs, we have another model classification called data-driven attribution, which is now the default design used in Google Analytics.

What Is Data-Driven Attribution?

How is data-driven attribution different from the heuristic attribution models?

Here are some highlights of the differences:

  • In a heuristic design, the rule of attribution is predetermined. Regardless of first-touch, last-touch, linear, or position-based model, the attribution guidelines are set in advance and then used to the information. In a data-driven attribution model, the attribution rule is produced based on historic data, and for that reason, it is unique for each scenario.
  • A heuristic model looks at only the paths that cause a conversion and ignores the non-converting paths. A data-driven model uses data from both converting and non-converting paths.
  • A heuristic design associates conversions to a channel based upon how many touches a touch point has with regard to the attribution rules. In a data-driven model, the attribution is made based upon the effect of the touches of each touch point.

How To Examine The Result Of A Touch Point

A common algorithm utilized by data-driven attribution is called Markov Chain. At the heart of the Markov Chain algorithm is an idea called the Elimination Effect.

The Removal Effect, as the name recommends, is the influence on conversion rate when a touch point is eliminated from the pathing information.

This short article will not enter into the mathematical information of the Markov Chain algorithm.

Below is an example showing how the algorithm attributes conversion to each touch point.

The Elimination Result

Presuming we have a situation where there are 100 conversions from 1,000 visitors coming to a site through 3 channels, Channel A, B, & C. In this case, the conversion rate is 10%.

Intuitively, if a particular channel is eliminated from the conversion courses, those paths including that specific channel will be “cut off” and end with fewer conversions overall.

If the conversion rate is lowered to 5%, 2%, and 1% when Channels A, B, & C are removed from the data, respectively, we can calculate the Removal Effect as the percentage decline of the conversion rate when a specific channel is gotten rid of using the formula:

Image from author, November 2022 Then, the last step is associating conversions to each channel based on the share of the Elimination Result of each channel. Here is the attribution result: Channel Removal Effect Share of Elimination Effect Attributed Conversions

A 1–(5%/ 10% )=0.5 0.5/(0.5 +0.8+ 0.9 )=0.23 100 * 0.23 =23 B 1–(2%/ 10%
) = 0.8 0.8/ (0.5 + 0.8 + 0.9) = 0.36 100 * 0.36 = 36
C 1– (1%/ 10% )=0.9 0.9/(0.5 +0.8 + 0.9) = 0.41 100
* 0.41 = 41 In a nutshell, data-driven attribution does not rely on the number or

position of the touch points but on the effect of those touch points on conversion as the basis of attribution. Multi-Touch Attribution With Google Analytics Enough

of theories, let’s look at how we can utilize the ubiquitous Google Analytics to perform multi-touch attribution analysis. As Google will stop supporting Universal Analytics(UA)from July 2023,

this tutorial will be based on Google Analytics 4(GA4 )and we’ll use Google’s Product Store demo account as an example. In GA4, the attribution reports are under Marketing Photo as shown listed below on the left navigation menu. After landing on the Marketing Photo page, the first step is picking a proper conversion occasion. GA4, by default, consists of all conversion occasions for its attribution reports.

To prevent confusion, I extremely recommend you select just one conversion occasion(“purchase”in the

below example)for the analysis. Screenshot from GA4, November 2022 Understand The Conversion Courses In

GA4 Under the Attribution area on the left navigation bar, you can open the Conversion Paths report. Scroll down to the conversion course table, which reveals all the courses resulting in conversion. At the top of this table, you can find the average number of days and number

of touch points that cause conversions. Screenshot from GA4, November 2022 In this example, you can see that Google consumers take, typically

, almost 9 days and 6 gos to before making a purchase on its Product Shop. Find Each Channel’s Contribution In GA4 Next, click the All Channels report under the Performance section on the left navigation bar. In this report, you can find the associated conversions for each channel of your chosen conversion occasion–“purchase”, in this case. Screenshot from GA4, November 2022 Now, you understand Organic Browse, together with Direct and Email, drove most of the purchases on Google’s Merchandise Store. Examine Results

From Different Attribution Models In GA4 By default, GA4 uses the data-driven attribution design to determine the number of credits each channel gets. However, you can take a look at how

different attribution models designate credits for each channel. Click Model Comparison under the Attribution section on the left navigation bar. For instance, comparing the data-driven attribution design with the first touch attribution model (aka” very first click model “in the below figure), you can see more conversions are attributed to Organic Browse under the very first click model (735 )than the data-driven design (646.80). On the other hand, Email has more associated conversions under the data-driven attribution design(727.82 )than the very first click model (552 ).< img src="// www.w3.org/2000/svg%22%20viewBox=%220%200%201666%20676%22%3E%3C/svg%3E" alt="Attribution models for channel organizing GA4"width=" 1666"height ="676 "data-src ="https://cdn.searchenginejournal.com/wp-content/uploads/2022/11/attribution-model-comparison-6371b20148538-sej.png"/ > Screenshot from GA4, November 2022 The information informs us that Organic Search plays a crucial function in bringing prospective consumers to the store, however it requires help from other channels to transform visitors(i.e., for customers to make actual purchases). On the other

hand, Email, by nature, interacts with visitors who have actually visited the website in the past and helps to convert returning visitors who initially pertained to the website from other channels. Which Attribution Design Is The Best? A common concern, when it pertains to attribution model comparison, is which attribution design is the very best. I ‘d argue this is the incorrect question for marketers to ask. The truth is that no one model is absolutely better than the others as each model shows one aspect of the consumer journey. Online marketers ought to accept numerous designs as they please. From Channel-Based To Pageview-Based Attribution Google Analytics is simple to utilize, however it works well for channel-based attribution. If you want to further understand how consumers navigate through your website before converting, and what pages influence their choices, you require to carry out attribution analysis on pageviews.

While Google Analytics doesn’t support pageview-based

attribution, there are other tools you can utilize. We recently carried out such a pageview-based attribution analysis on AdRoll’s site and I ‘d enjoy to show you the steps we went through and what we learned. Gather Pageview Series Data The very first and most difficult step is gathering information

on the sequence of pageviews for each visitor on your website. The majority of web analytics systems record this information in some type

. If your analytics system doesn’t supply a way to extract the data from the user interface, you may require to pull the information from the system’s database.

Similar to the steps we went through on GA4

, the first step is defining the conversion. With pageview-based attribution analysis, you also need to identify the pages that are

part of the conversion procedure. As an example, for an ecommerce website with online purchase as the conversion occasion, the shopping cart page, the billing page, and the

order confirmation page become part of the conversion process, as every conversion goes through those pages. You need to omit those pages from the pageview information because you don’t need an attribution analysis to tell you those

pages are very important for transforming your clients. The function of this analysis is to comprehend what pages your potential clients went to prior to the conversion event and how they influenced the customers’choices. Prepare Your Data For Attribution Analysis Once the data is all set, the next action is to sum up and control your data into the following four-column format. Here is an example.

Screenshot from author, November 2022 The Path column shows all the pageview series. You can utilize any unique page identifier, however I ‘d advise utilizing the url or page path since it permits you to analyze the outcome by page types using the url structure.”>”is a separator utilized in between pages. The Total_Conversions column reveals the total number of conversions a specific pageview path caused. The Total_Conversion_Value column shows the total monetary worth of the conversions from a specific pageview path. This column is

optional and is primarily applicable to ecommerce websites. The Total_Null column reveals the total variety of times a particular pageview path stopped working to transform. Build Your Page-Level Attribution Models To build the attribution models, we utilize the open-source library called

ChannelAttribution. While this library was initially created for use in R and Python programs languages, the authors

now provide a totally free Web app for it, so we can use this library without composing any code. Upon signing into the Web app, you can submit your data and start constructing the designs. For first-time users, I

‘d suggest clicking the Load Demo Data button for a trial run. Make certain to examine the specification configuration with the demonstration data. Screenshot from author, November 2022 When you’re ready, click the Run button to develop the models. Once the designs are created, you’ll be directed to the Output tab , which displays the attribution results from four different attribution designs– first-touch, last-touch, linear, and data-drive(Markov Chain). Remember to download the result data for more analysis. For your recommendation, while this tool is called ChannelAttribution, it’s not restricted to channel-specific data. Considering that the attribution modeling system is agnostic to the type of information provided to it, it ‘d attribute conversions to channels if channel-specific data is supplied, and to web pages if pageview information is offered. Examine Your Attribution Data Arrange Pages Into Page Groups Depending upon the number of pages on your website, it might make more sense to initially evaluate your attribution data by page groups instead of individual pages. A page group can contain as few as simply one page to as lots of pages as you desire, as long as it makes good sense to you. Taking AdRoll’s site as an example, we have a Homepage group which contains just

the homepage and a Blog group that contains all of our blog posts. For

ecommerce sites, you may consider organizing your pages by item classifications also. Beginning with page groups rather of individual pages permits marketers to have an overview

of the attribution results throughout different parts of the site. You can always drill below the page group to private pages when required. Recognize The Entries And Exits Of The Conversion Paths After all the information preparation and model structure, let’s get to the enjoyable part– the analysis. I

‘d suggest first recognizing the pages that your prospective customers enter your website and the

pages that direct them to transform by analyzing the patterns of the first-touch and last-touch attribution models. Pages with particularly high first-touch and last-touch attribution values are the starting points and endpoints, respectively, of the conversion paths.

These are what I call gateway pages. Make certain these pages are enhanced for conversion. Remember that this type of entrance page may not have extremely high traffic volume.

For example, as a SaaS platform, AdRoll’s prices page doesn’t have high traffic volume compared to some other pages on the website but it’s the page numerous visitors gone to prior to converting. Discover Other Pages With Strong Impact On Clients’Decisions After the gateway pages, the next step is to find out what other pages have a high influence on your consumers’ decisions. For this analysis, we look for non-gateway pages with high attribution value under the Markov Chain designs.

Taking the group of product function pages on AdRoll.com as an example, the pattern

of their attribution worth throughout the four designs(shown below )reveals they have the greatest attribution worth under the Markov Chain model, followed by the direct model. This is a sign that they are

checked out in the middle of the conversion paths and played an important function in influencing clients’choices. Image from author, November 2022

These kinds of pages are also prime prospects for conversion rate optimization (CRO). Making them easier to be discovered by your site visitors and their material more convincing would help raise your conversion rate. To Evaluate Multi-touch attribution permits a business to understand the contribution of different marketing channels and determine chances to more enhance the conversion courses. Start merely with Google Analytics for channel-based attribution. Then, dig much deeper into a customer’s path to conversion with pageview-based attribution. Don’t fret about picking the very best attribution model. Utilize multiple attribution designs, as each attribution design shows various elements of the client journey.
