Stape's GTM Server Side extension for Magento 2 simplifies the process and opens up the world of server-side tagging for Magento stores.

Another advantage of using this extension is the extended cookie lifetime when utilizing a custom domain for the server Google Tag Manager container, which enhances tracking accuracy. Furthermore, the Stape Power-Up Cookie Keeper feature restores marketing cookies in Safari 16.4+.

With the Magento plugin it is possible to remove 3rd party pixels from the browser to cloud servers and therefore increase your site page speed.
