Answer 1

METHOD TO ADD GOOGLE TAG MANAGER TO MAGENTO 2 STORE

In Magento 2, you can easily add the Google Tag Manager without any need for a third-party extension.

To add Google Tag Manager to your Magento 2 store, all you need to do is add your unique Google Tag Manager code to your theme.

The Google Tag Manager code is divided into two parts – Script & NoScript.

You need to put these code snippets into two separate phtml template head and body files as shown below.

// YourTheme/Magento_Theme/templates/html/gtm_head.phtml

<script>..</script> <!-- GTM code -->

// YourTheme/Magento_Theme/templates/html/gtm_body.phtml

<noscript>..</noscript> <!-- GTM code -->

Now, we also need to load these files correspondingly through the default default.xml file.

<!-- YourTheme/Magento_Theme/layout/default.xml -->

<referenceContainer name="head.additional">

<block class="Magento\Framework\View\Element\Template" name="gtm.head" before="-" template="Magento_Theme::html/gtm_head.phtml" />

</referenceContainer>

<referenceContainer name="after.body.start">

<block class="Magento\Framework\View\Element\Template" name="gtm.body" before="-" template="Magento_Theme::html/gtm_body.phtml" />

</referenceContainer>

Your Google Tag Manager code is finally added and now you can set up your Google Analytics for monitoring and reporting of your Magento 2 store.

Answer 2

Open your Magento Admin Panel and move to Content > Design > Configuration > Edit the Store View > Other Settings> HTML Head.

Paste the code you got from GTM for the tag here.
