<!-- 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.
