A Practical Guide To Multi-Touch Attribution

Posted by

The customer journey includes numerous interactions between the customer and the merchant or company.

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

According to Salesforce.com, it takes, typically, six to 8 touches to create a lead in the B2B area.

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

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

Conducting a multi-touch attribution analysis can assist marketers comprehend the consumer journey and identify opportunities to more optimize the conversion courses.

In this short article, you will discover the fundamentals of multi-touch attribution, and the steps of performing multi-touch attribution analysis with quickly accessible tools.

What To Think About Before Performing Multi-Touch Attribution Analysis

Define Business Goal

What do you want to attain from the multi-touch attribution analysis?

Do you want to assess the return on investment (ROI) of a specific marketing channel, understand your client’s journey, or determine crucial pages on your site for A/B testing?

Different organization objectives might need various attribution analysis methods.

Defining what you want to attain from the start helps you get the outcomes much faster.

Specify Conversion

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

For ecommerce sites, it’s usually buying, defined by the order conclusion occasion.

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

Different kinds of conversion likely have various conversion courses.

If you want to perform multi-touch attribution on numerous preferred 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 clients.

If this is your very first time running a multi-touch attribution analysis, I would advise defining it as a visit to your site from a specific marketing channel. Channel-based attribution is simple to conduct, and it might offer you a summary of the consumer journey.

If you want to comprehend how your customers engage with your site, I would suggest defining touchpoints based on pageviews on your site.

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

Regardless of your touch point meaning, the attribution mechanism is the very same. The more granular the touch points are specified, the more comprehensive the attribution analysis is.

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

You’ll find out about how to utilize Google Analytics and another open-source tool to perform those attribution analyses.

An Introduction To Multi-Touch Attribution Models

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

The most basic attribution design is to offer all the credit to either the first touch point, for bringing in the client initially, or the last touch point, for driving the conversion.

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

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

Then, how about designating credit evenly across all touch points involved in transforming a customer? That sounds reasonable– and this is precisely how the linear attribution model works.

However, designating credit evenly throughout all touch points assumes the touch points are equally crucial, which does not seem “reasonable”, either.

Some argue the touch points near the end of the conversion courses are more vital, while others are in favor of the opposite. As an outcome, we have the position-based attribution model that enables marketers to provide different weights to touchpoints based upon their places in the conversion paths.

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

In addition to heuristic models, we have another design category called data-driven attribution, which is now the default design utilized in Google Analytics.

What Is Data-Driven Attribution?

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

Here are some highlights of the distinctions:

  • In a heuristic design, the rule of attribution is predetermined. Regardless of first-touch, last-touch, linear, or position-based model, the attribution rules are embeded in advance and then applied to the data. In a data-driven attribution model, the attribution rule is created based on historical data, and for that reason, it is unique for each situation.
  • A heuristic model looks at only the courses that cause a conversion and ignores the non-converting paths. A data-driven design utilizes information from both converting and non-converting paths.
  • A heuristic design attributes conversions to a channel based on how many touches a touch point has with respect to the attribution guidelines. In a data-driven design, the attribution is made based upon the effect of the touches of each touch point.

How To Assess The Result Of A Touch Point

A typical algorithm used by data-driven attribution is called Markov Chain. At the heart of the Markov Chain algorithm is a principle called the Elimination Impact.

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

This short article will not go into the mathematical details of the Markov Chain algorithm.

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

The Elimination Impact

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

Intuitively, if a specific channel is gotten rid of from the conversion paths, those paths involving that specific channel will be “cut off” and end with less conversions in general.

If the conversion rate is decreased to 5%, 2%, and 1% when Channels A, B, & C are gotten rid of from the information, respectively, we can determine the Elimination Effect as the portion decline of the conversion rate when a particular channel is eliminated using the formula:

Image from author, November 2022 Then, the last step is associating conversions to each channel based upon the share of the Elimination Impact of each channel. Here is the attribution result: Channel Removal Effect Share of Removal Result Associated 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 take a look at how we can use the ubiquitous Google Analytics to carry out 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 Advertising Photo as shown below on the left navigation menu. After landing on the Advertising Picture page, the first step is choosing a proper conversion occasion. GA4, by default, consists of all conversion occasions for its attribution reports.

To prevent confusion, I highly recommend you choose 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 course table, which shows all the courses leading to conversion. At the top of this table, you can discover the typical number of days and number

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

, practically 9 days and 6 sees prior to purchasing on its Merchandise Store. Find Each Channel’s Contribution In GA4 Next, click the All Channels report under the Performance area on the left navigation bar. In this report, you can discover the attributed conversions for each channel of your picked conversion occasion–“purchase”, in this case. Screenshot from GA4, November 2022 Now, you understand Organic Browse, together with Direct and Email, drove the majority of the purchases on Google’s Merchandise Store. Take a look at Outcomes

From Different Attribution Designs In GA4 By default, GA4 utilizes the data-driven attribution design to identify how many credits each channel gets. However, you can analyze how

various attribution models assign credits for each channel. Click Model Contrast under the Attribution area on the left navigation bar. For instance, comparing the data-driven attribution model with the very first touch attribution design (aka” first click model “in the below figure), you can see more conversions are credited to Organic Browse under the very first click design (735 )than the data-driven model (646.80). On the other hand, Email has actually more attributed 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 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 data informs us that Organic Browse plays an essential role in bringing possible customers to the shop, however it requires aid from other channels to convert visitors(i.e., for clients to make real purchases). On the other

hand, Email, by nature, interacts with visitors who have visited the website in the past and helps to convert returning visitors who at first came to the site from other channels. Which Attribution Design Is The Very Best? A common concern, when it comes to attribution model contrast, is which attribution design is the very best. I ‘d argue this is the wrong concern for online marketers to ask. The reality is that no one design is absolutely much better than the others as each design illustrates one aspect of the customer journey. Online marketers ought to welcome several models as they see fit. From Channel-Based To Pageview-Based Attribution Google Analytics is simple to use, but it works well for channel-based attribution. If you want to further understand how consumers browse through your website before converting, and what pages influence their decisions, you need to carry out attribution analysis on pageviews.

While Google Analytics doesn’t support pageview-based

attribution, there are other tools you can use. 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 discovered. Gather Pageview Sequence Data The very first and most difficult action is gathering data

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

. If your analytics system doesn’t supply a method to extract the information from the interface, you might require to pull the information from the system’s database.

Comparable to the actions we went through on GA4

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

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

order confirmation page are part of the conversion process, as every conversion goes through those pages. You ought to leave out those pages from the pageview data because you do not require an attribution analysis to inform you those

pages are very important for converting your consumers. The function of this analysis is to understand what pages your potential clients visited prior to the conversion occasion and how they influenced the customers’choices. Prepare Your Data For Attribution Analysis When the information is all set, the next action is to sum up and manipulate your information into the following four-column format. Here is an example.

Screenshot from author, November 2022 The Course column shows all the pageview sequences. You can use any special page identifier, but I ‘d advise utilizing the url or page course since 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 overall variety of conversions a specific pageview path resulted in. The Total_Conversion_Value column shows the overall monetary worth of the conversions from a particular pageview path. This column is

optional and is primarily relevant to ecommerce websites. The Total_Null column reveals the total number of times a particular pageview path failed to transform. Develop Your Page-Level Attribution Designs To construct the attribution designs, we take advantage of the open-source library called

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

now provide a totally free Web app for it, so we can utilize this library without composing any code. Upon signing into the Web app, you can upload your information and start developing the models. For first-time users, I

‘d suggest clicking the Load Demo Data button for a trial run. Be sure to examine the specification configuration with the demo information. Screenshot from author, November 2022 When you’re prepared, click the Run button to develop the models. When the designs are produced, you’ll be directed to the Output tab , which shows the attribution results from 4 various attribution designs– first-touch, last-touch, direct, and data-drive(Markov Chain). Remember to download the result data for further analysis. For your reference, while this tool is called ChannelAttribution, it’s not restricted to channel-specific data. Given that the attribution modeling mechanism is agnostic to the type of data given to it, it ‘d attribute conversions to channels if channel-specific data is provided, and to web pages if pageview information is provided. Evaluate Your Attribution Data Organize Pages Into Page Groups Depending on the variety of pages on your site, it may make more sense to first analyze your attribution data by page groups instead of specific pages. A page group can contain as couple of as just one page to as lots of pages as you desire, as long as it makes good sense to you. Taking AdRoll’s website as an example, we have a Homepage group that contains simply

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

ecommerce sites, you may consider grouping your pages by item categories too. Beginning with page groups rather of individual pages enables online marketers to have a summary

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

‘d recommend first identifying the pages that your prospective customers enter your site and the

pages that direct them to transform by examining 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 sure these pages are optimized for conversion. Keep in mind that this type of entrance page might not have extremely high traffic volume.

For instance, 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 many visitors visited before converting. Discover Other Pages With Strong Impact On Consumers’Decisions After the entrance pages, the next action is to find out what other pages have a high influence on your consumers’ decisions. For this analysis, we try to find 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 value across the four models(revealed below )reveals they have the highest attribution worth under the Markov Chain design, followed by the direct design. This is a sign that they are

gone to in the middle of the conversion paths and played a crucial function in influencing clients’decisions. Image from author, November 2022

These types of pages are likewise prime candidates for conversion rate optimization (CRO). Making them easier to be discovered by your website visitors and their content more persuading would assist raise your conversion rate. To Summarize Multi-touch attribution permits a company to understand the contribution of different marketing channels and recognize opportunities to further optimize the conversion courses. Start simply with Google Analytics for channel-based attribution. Then, dig deeper into a consumer’s pathway to conversion with pageview-based attribution. Do not stress over picking the very best attribution design. Leverage multiple attribution models, as each attribution model shows various aspects of the customer journey.
