Add Google Tag Manager to Magento 2 by using an extension

Instead of integrating this gadget with the hard way, it’s much easier for non-expertise businesspeople to add GTM on their own using an additional module. Besides, Magento 2 Google Tag Manager extension by Mageplaza also features many more functionalities that await you to install to the store backend.

Note: If you already have a GTM account, please skip these steps.

Step 1: Create a Google Tag Manager account

First off, before getting back to the Magento admin panel, you should register a Google Tag Manager account via this link here.

Then, input the required information for the registration process for your account.

You can set up the “container”. The container is a set of rules, tags and macros which is configured for a specific site. You should fill the container with your website’s domain name. For stores that have multiple store sites, you will have to create several containers. Also, you should set it as “Web” Container as you are running a website, not a mobile app. Then, click Create.

Step 2: Copy the snippet of the GTM install code

After that, you can click on the section as follows:

Then, copy the code generated by the GTM system like below and paste it into each page of your store site.

Step 3: Get the Container ID

Finally, you can access the Admin section to collect Container ID to install in Magento.

How to configure Magento 2 Google Tag Manager

When you finished adding Google Tag Manager to Magento 2, now it’s time to configure the module:

In the ID Variable Base On section: Select how the ID value of the product is displayed, either according to the product ID or product SKU.

For the Google Tag ID field, admins need to paste the paste container ID you got earlier on the Admin page to update some information on an event. The event can be set in category page, product page when adding to cart, remove from cart, order success, search, checkout default or checkout page of Single page Checkout extensions which help shorten checkout process to only 6 steps within a page and optimize the checkout process for customers.

If the field is left blank or filled with incorrect information, the Container ID will unable to display information in detail.

How to Create New Google Tag Manager Tags

Let’s get back to the Workspace page to create new GTM tags.

• Step 1: Click on New Tag in the left sidebar

• Step 2: Set up the tag with the necessary information

  • Tag configuration: Select a tag type to begin set up
  • Triggering: Choose a trigger to make this tag fire

Select the appropriate tag type (e.g., Google Analytics, Facebook Pixel)

Now, set up the tag configuration with suitable information based on your needs.

Set Triggers

Define when the tag should fire (e.g., page views, clicks).

If you want to add a new trigger, click on the + sign at the top right corner.

Then, choose the trigger type from the list given:

Page View

• Consent Initialization
• Initialization
• Page View
• DOM Ready
• Window Loaded

Click

• All Elements
• Just Links

User Engagement

• Element Visibility
• Form Submission
• Scroll Depth
• YouTube Video

Other

• Custom Event
• History Change
• JavaScript Error
• Timer
• Trigger Group

After choosing the trigger type, select the place where this trigger fires. Each trigger type brings individual settings to fire. Fill in the information required, and save it.

• Step 3: Save Tag

Note: If you are utilizing Google Tag Manager to control your Magento 2 enhanced ecommerce (Google Analytics), try to avoid duplicating your data!

Make sure to remove the current Google Analytics tracking code from your pages. Otherwise, the old GA code will still collect data, leading to the new GTM tag reporting with duplicate data. Particularly, to delete the tracking code, you need to click on Admin > Container Settings > More menu (as three vertical dots) > Settings > Delete. You will have 30 days to change your mind and restore the container. After that time, Google will permanently delete it.

Ensure you won’t make this mistake. After all, nobody wants to receive duplicated data, right?
