A Practical Guide To Multi-Touch Attribution

Posted by

The client journey involves multiple interactions between the consumer and the merchant or service provider.

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

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

The variety of touchpoints is even greater for a consumer purchase.

Multi-touch attribution is the mechanism to evaluate each touch point’s contribution towards conversion and provides the suitable credits to every touch point associated with the consumer journey.

Carrying out a multi-touch attribution analysis can assist marketers understand the consumer journey and recognize chances to further enhance the conversion paths.

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

What To Think About Before Conducting Multi-Touch Attribution Analysis

Define Business Objective

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

Do you want to evaluate the roi (ROI) of a specific marketing channel, comprehend your customer’s journey, or recognize vital pages on your website for A/B testing?

Various company goals might require various attribution analysis methods.

Specifying what you wish to attain from the beginning helps you get the results quicker.

Specify Conversion

Conversion is the wanted action you desire your clients to take.

For ecommerce sites, it’s normally buying, defined by the order completion occasion.

For other markets, it might be an account sign-up or a membership.

Different kinds of conversion likely have various conversion courses.

If you want to perform multi-touch attribution on multiple preferred actions, I would recommend separating them into different analyses to avoid confusion.

Define Touch Point

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

If this is your first time running a multi-touch attribution analysis, I would advise defining it as a check out to your site from a particular marketing channel. Channel-based attribution is simple to conduct, and it might give you a summary of the client journey.

If you wish to understand how your clients communicate with your site, I would recommend specifying touchpoints based on pageviews on your site.

If you wish to include interactions outside of 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 data.

Regardless of your touch point meaning, 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 concentrate 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 Designs

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

The simplest attribution design is to give all the credit to either the very first touch point, for generating the customer at first, or the last touch point, for driving the conversion.

These two designs are called the first-touch attribution model and the last-touch attribution model, respectively.

Obviously, neither the first-touch nor the last-touch attribution design is “reasonable” to the remainder of the touch points.

Then, how about allocating credit uniformly throughout all touch points involved in converting a client? That sounds sensible– and this is precisely how the direct attribution model works.

Nevertheless, allocating credit uniformly throughout all touch points assumes the touch points are similarly essential, which does not appear “reasonable”, either.

Some argue the touch points near completion of the conversion paths are more important, while others are in favor of the opposite. As a result, we have the position-based attribution design that permits marketers to provide different weights to touchpoints based on their areas in the conversion courses.

All the designs mentioned above are under the category of heuristic, or rule-based, attribution models.

In addition to heuristic designs, we have another design category 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 distinctions:

  • In a heuristic design, the guideline of attribution is predetermined. No matter first-touch, last-touch, linear, or position-based design, the attribution rules are embeded in advance and after that used to the information. In a data-driven attribution design, the attribution rule is produced based upon historical data, and for that reason, it is unique for each situation.
  • A heuristic design looks at just the paths that cause a conversion and overlooks the non-converting paths. A data-driven model utilizes information from both transforming and non-converting courses.
  • 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 impact of the touches of each touch point.

How To Assess The Effect 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 a concept called the Removal Result.

The Removal Effect, as the name recommends, is the impact on conversion rate when a touch point is removed from the pathing data.

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

Below is an example illustrating how the algorithm associates conversion to each touch point.

The Elimination Effect

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

Intuitively, if a certain channel is gotten rid of from the conversion paths, those courses including that particular channel will be “cut off” and end with fewer conversions in general.

If the conversion rate is decreased to 5%, 2%, and 1% when Channels A, B, & C are removed from the information, respectively, we can calculate the Removal Impact as the percentage decline of the conversion rate when a particular channel is eliminated using the formula:

Image from author, November 2022 Then, the last step is attributing conversions to each channel based on the share of the Removal Impact of each channel. Here is the attribution outcome: Channel Elimination Result Share of Elimination Impact 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 impact 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 conduct multi-touch attribution analysis. As Google will stop supporting Universal Analytics(UA)from July 2023,

this tutorial will be based upon Google Analytics 4(GA4 )and we’ll use Google’s Product Shop demonstration account as an example. In GA4, the attribution reports are under Marketing Snapshot as revealed below on the left navigation menu. After landing on the Marketing Picture page, the first step is selecting an appropriate conversion occasion. GA4, by default, includes all conversion events for its attribution reports.

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

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

GA4 Under the Attribution section on the left navigation bar, you can open the Conversion Paths report. Scroll down to the conversion path table, which reveals all the paths resulting in conversion. At the top of this table, you can discover 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 clients take, usually

, almost 9 days and 6 check outs prior to buying on its Merchandise Shop. Discover Each Channel’s Contribution In GA4 Next, click the All Channels report under the Efficiency section on the left navigation bar. In this report, you can find the associated conversions for each channel of your picked conversion occasion–“purchase”, in this case. Screenshot from GA4, November 2022 Now, you know Organic Search, together with Direct and Email, drove the majority of the purchases on Google’s Product Shop. Analyze Results

From Various Attribution Designs In GA4 By default, GA4 utilizes the data-driven attribution design to identify how many credits each channel gets. Nevertheless, you can take a look at how

various attribution designs assign credits for each channel. Click Model Comparison under the Attribution section on the left navigation bar. For example, comparing the data-driven attribution design with the first touch attribution model (aka” first click design “in the below figure), you can see more conversions are attributed to Organic Browse under the first click model (735 )than the data-driven design (646.80). On the other hand, Email has more attributed conversions under the data-driven attribution model(727.82 )than the first click model (552 ).< img src="// www.w3.org/2000/svg%22%20viewBox=%220%200%201666%20676%22%3E%3C/svg%3E" alt="Attribution designs 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 tells us that Organic Search plays a crucial role in bringing prospective customers to the shop, but it requires aid from other channels to transform visitors(i.e., for consumers to make real purchases). On the other

hand, Email, by nature, connects with visitors who have actually checked out the website before and helps to convert returning visitors who at first concerned the website from other channels. Which Attribution Model Is The Very Best? A typical concern, when it concerns attribution model contrast, is which attribution model is the very best. I ‘d argue this is the wrong question for marketers to ask. The truth is that no one design is definitely better than the others as each model highlights one aspect of the customer journey. Marketers need to accept numerous models as they see fit. From Channel-Based To Pageview-Based Attribution Google Analytics is easy to utilize, but it works well for channel-based attribution. If you wish to even more understand how consumers navigate through your site prior to transforming, and what pages influence their choices, you require to conduct attribution analysis on pageviews.

While Google Analytics doesn’t support pageview-based

attribution, there are other tools you can utilize. We recently performed such a pageview-based attribution analysis on AdRoll’s website and I ‘d be happy to share with you the steps we went through and what we discovered. Collect Pageview Sequence Information The very first and most difficult action is collecting data

on the series of pageviews for each visitor on your website. Many web analytics systems record this information in some type

. If your analytics system does not supply a method to extract the data from the interface, you may need to pull the data from the system’s database.

Similar to the actions we went through on GA4

, the initial 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 are part of the conversion procedure, as every conversion goes through those pages. You ought to exclude those pages from the pageview data considering that you don’t need an attribution analysis to inform you those

pages are important for transforming your consumers. The purpose of this analysis is to understand what pages your potential consumers checked out prior to the conversion event and how they affected the clients’choices. Prepare Your Information For Attribution Analysis As soon as the data is prepared, the next action is to summarize and manipulate your data into the following four-column format. Here is an example.

Screenshot from author, November 2022 The Course column reveals all the pageview sequences. You can use any special page identifier, however I ‘d advise utilizing the url or page path because it allows you to evaluate 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 course caused. The Total_Conversion_Value column reveals the total financial worth of the conversions from a specific pageview course. This column is

optional and is mainly relevant to ecommerce sites. The Total_Null column reveals the total variety of times a particular pageview course stopped working to transform. Develop Your Page-Level Attribution Models To build the attribution designs, we take advantage of the open-source library called

ChannelAttribution. While this library was originally created for usage in R and Python shows languages, the authors

now offer a complimentary Web app for it, so we can use this library without writing any code. Upon signing into the Web app, you can upload your data and start constructing the designs. For newbie users, I

‘d recommend clicking the Load Demonstration Data button for a trial run. Be sure to analyze the parameter configuration with the demonstration information. Screenshot from author, November 2022 When you’re prepared, click the Run button to develop the models. As soon as the designs are developed, you’ll be directed to the Output tab , which displays the attribution arises from four various attribution models– first-touch, last-touch, linear, and data-drive(Markov Chain). Keep in mind to download the outcome data for more analysis. For your recommendation, while this tool is called ChannelAttribution, it’s not limited to channel-specific data. Because the attribution modeling mechanism is agnostic to the kind of data offered to it, it ‘d associate conversions to channels if channel-specific information is offered, and to web pages if pageview data is provided. Examine Your Attribution Data Arrange Pages Into Page Groups Depending on the variety of pages on your website, it might make more sense to first examine your attribution data by page groups instead of private pages. A page group can include as couple of as just one page to as numerous pages as you want, as long as it makes good sense to you. Taking AdRoll’s site as an example, we have a Homepage group that contains simply

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

ecommerce websites, you might think about grouping your pages by product classifications as well. Starting with page groups rather of specific pages allows marketers to have a summary

of the attribution results throughout various parts of the website. You can constantly drill below the page group to individual pages when required. Recognize The Entries And Exits Of The Conversion Courses After all the information preparation and model building, let’s get to the fun part– the analysis. I

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

pages that direct them to transform by taking a look at the patterns of the first-touch and last-touch attribution models. Pages with especially high first-touch and last-touch attribution worths are the starting points and endpoints, respectively, of the conversion courses.

These are what I call entrance pages. Ensure these pages are optimized for conversion. Remember that this type of gateway page may not have really 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 site however it’s the page many visitors gone to prior to converting. Discover Other Pages With Strong Impact On Consumers’Decisions After the entrance pages, the next action is to discover what other pages have a high influence on your clients’ decisions. For this analysis, we search for non-gateway pages with high attribution worth under the Markov Chain designs.

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

of their attribution worth throughout the four models(shown listed below )shows they have the greatest attribution worth under the Markov Chain model, followed by the direct model. This is an indication that they are

visited in the middle of the conversion paths and played an essential function in influencing clients’decisions. Image from author, November 2022

These kinds of pages are also prime prospects for conversion rate optimization (CRO). Making them much easier to be found by your website visitors and their material more convincing would help lift your conversion rate. To Recap Multi-touch attribution permits a company to comprehend the contribution of various marketing channels and identify opportunities to further optimize the conversion paths. Start just with Google Analytics for channel-based attribution. Then, dig much deeper into a client’s path to conversion with pageview-based attribution. Do not worry about picking the very best attribution design. Utilize multiple attribution models, as each attribution design shows various elements of the client journey.
