How to Track Thinkific Purchases with Google Analytics 4

This guide will help Thinkific Course Creators measure which traffic sources are leading to sales, by tracking purchases with Google Analytics 4 (GA4), so they can optimise their marketing.
While Thinkific has an integration with Google Analytics 4 via an app from their App Store, it only tracks page views and does not track conversions such as purchases or sign-ups. To track Thinkific conversions and other important events with Google Analytics 4, Google Tag Manager (GTM) needs to be used.

Add Google Tag Manager to Thinkific

If your are not yet using Google Tag Manager on your Thinkific site, this section will guide you through its implementation.

Google Tag Manager is a tag management system that allows you to quickly and easily setup measurement codes (tags) on you website such as GA4, Meta Pixel, Google Ads Conversions, etc.

There are two methods to add Google Tag Manager to Thinkific:

In your site’s Theme Code.
In your site’s Footer Code.

There are some drawbacks to adding GTM to the Footer, so this guide will not cover that route. If you would like to find out more about adding GTM to the footer, it is covered in Thinkific’s documentation.

Create a Google Tag Manager Account if You Don’t Have one

If you do not have a Google Tag Manager account, you will need a Google Account, such as a GMail or Google Workspace, to create one.
Go to https://tagmanager.google.com/
If you are not already logged in the browser with a Google Account, you will be prompted to sign in with one. Once signed in, click the Create Account button to the top right.

On the next screen:

Enter and Account Name (it can be anything you like).
select your Country.
Enter a Container name (it can be anything but typically it is the website the container is related to).
Choose Web for Target platform.
Click the Create button.

Click Yes to accept the Terms of service.

You will then be presented with the code to be added to Thinkific.

Add GA4 Recommended Events Data Layer to Thinkific

What is the Data Layer?

The Data Layer is a place where you can put information about your website while the user interacts with your site. If the user visits a particular page, information about that page can be put in the Data Layer. In this guide, we are going to put information about Purchases and Sing-Up in the Data Layer.
Google Tag Manager detects when information is put into the Data Layer and can use it for Triggers that then fires Tags.

Add Purchase Event Data Layer to Thinkific

Go to Settings > Code & analytics

Copy the code below

<!-- GA4 Data Layer purchase event -->
<script>
  window.dataLayer = window.dataLayer || [];
  window.dataLayer.push({ ecommerce: null });  // Clear the previous ecommerce object.
  window.dataLayer.push({
    event: "purchase",
    ecommerce: {
      transaction_id: "{{order_number}}",
      value: {{total_price}},
      currency: "USD",
      items: [
        {
          item_id: "{{product_id}}",
          item_name: "{{product_name}}",
          price: {{total_price}},
          quantity: 1,
          affiliation: "{{referral_code}}"
        }
      ]
    }
  });
</script>
<!-- End GA4 Data Layer purchase event -->

In the Order tracking code section, paste the code and then click the SAVE button.

Copy the code below.

<!-- GA4 Data Layer sign-up event -->
<script>
  window.dataLayer = window.dataLayer || [];
  dataLayer.push({
    event: 'sign_up',
    user_id: '{{id}}'
  });
</script>
<!-- End GA4 Data Layer sign-up event -->

In the Signup tracking code section, paste the code and then click the SAVE button.

Which Traffic Sources Are Leading to Sales?

Now that measurement is in place, the next step would be to wait till you are certain you have some sales. The data won’t be in the reports right away though, so at minimum wait till the following day to check (it could take as much as 48 hours). Then go to:

Reports > Acquisition > Traffic acquisition.

Go to Traffic acquisition in GA4 reports

This report shows Traffic source by Sessions, and by default the left most column in Session default channel group. If you desire to see things broken down UTMs Session source / medium instead, go to:

Click the Session default channel group heading.
Select Session source / medium.

Animated gif showing selecting Session source / medium

You can also click the arrow in the heading of the Total revenue column to sort the column in descending order so you can see your traffic sources from highest to lowest sales.
The plus symbol to the right of heading of the first columns alloys you to add a second dimension. Eg. you can add Session campaign to evaluate if you have proper UTMs setup for your traffic sources (et. paid ad campaigns, etc.).

Click down arrow to sort by total revenue

Gotchas

GTM Does Not Fire On The Checkout Page – A Thank You Page is Needed

Google Tag Manager does not load on the Checkout Page. Instead, for the purchase flow, the sign_up event happens on the screen after the checkout page where credentials are entered, while the purchase event happens on the Thank You page.
For things to work there must be a native Thinkific Thank You page in the flow. If this is missing, or there is a totally custom thank you page, it will not work.

Previews of Courses Do Not Have a Thank You Page

The checkout flow for the Preview of a course does not have a Thank You Page. Instead, the sign-up event is fired after user password is entered and then goes directly to the Course Player. Google Tag Manager does not work in the Course Player. Since the purchase event is not fired, the details of Preview Courses are not captured and sent to GA4.
This is one of the reasons it is important to capture sign-ups.

GA4 Has a 24 to 48 Hour Processing Time

GA4 has a processing time of 24 to 48 hours. Therefore you may not see any data in the reports until that time period has elapsed. Usually data will show up the following day, but when troubleshooting the reports be sure to exclude the most recent 48 hours.

Next Steps

Learn How to Get Answers to Your Questions from GA4 Reports & Explorations

Google Analytics 4 has pre-configured reports that can be used to get answers to questions about traffic on the website. We so an example of this above in the Which Traffic Sources Are Leading to Sales? section. Other examples of questions and possible reports to get the answers include

Which pages get the most/least traffic?
- Reports > Engagement > Pages and screens
What where the traffic sources users initially came from?
- Reports > Acquisition > User acquisition

To go deeper, Google Analytics 4 also has Explorations which are found in the Explore tab.

Were did users go from the home page?
- Explore > Path exploration

Think about the questions you want to get the answers for related to you traffic and learn how to get the answers from the various reports and explorations.

Ensure Your Traffic is Identifiable Using UTMs

One of the most frustrating things is seeing traffic in your reports but still have no idea what the traffic is related to. Eg

Traffic from Facebook Ads
- Which ads are leading to purchases?
Traffic from your Instagram
- Did the traffic come from the Bio or a Story?
- Which story did traffic come from?
Traffic from your YouTube
- Which video did traffic come from?

Adding UTM (Urchin Tracking Module) parameters to the links you have control over in external platforms is how you will be able to answer the questions above and other questions related to where your traffic came from.

Leverage the Setup to Implement Conversion Tracking for Marketing Platforms

Setting up Thinkific purchase tracking with Google Analytics 4 from scratch was a bit of a slog. Now that it is in place though, not only do you reap the benefits of having your purchase data in Google Analytics 4, but you can leverage what has been setup to do conversion tracking for other marketing platforms.
