Google Tag Manager Server-Side Tracking: A Step-by-Step Tutorial

Frequently Asked Questions
Common questions about "Google Tag Manager (GTM) Server Side Tracking"
Google Tag Manager Server-Side Tracking moves analytics and advertising tags from the client (browser) to a server. The main benefits include improved website performance by reducing JavaScript load, greater control over data collection, and enhanced ability to manage how data is distributed to various platforms.
To set up a custom domain, go to Google Cloud Platform, select App Engine > Settings > Custom Domains, verify your domain ownership by adding DNS records, and then update your container settings in GTM with the new subdomain. This enables first-party cookies and improves tracking capabilities.
As shown in the video, the server-side container currently has limited built-in tags: Google Analytics Universal Analytics, Google Analytics App+Web (now GA4), and HTTP request tags. For other platforms like Facebook, you would need to create custom tag templates or wait for Google to add more built-in options.
Yes, using Google Cloud Platform for server-side tracking raises GDPR compliance concerns since data may be processed on US-based infrastructure. For better GDPR compliance, consider EU-based hosting solutions like gdpr-server-tracking.eu that provide servers physically located in the EU with no US ownership.
To modify your web container, update your Google Analytics settings variable by adding your server-side container URL as the Transport URL. You can then pause any redundant tags (like GA4) that you've replicated in your server-side container to reduce client-side code.
Google's solution offers a free tier with a single server, but recommended production setups with three servers incur Google Cloud Platform costs. Alternative EU-based solutions like gdpr-server-tracking.eu often provide more predictable pricing models while offering additional privacy features and GDPR compliance benefits.
Yes, as demonstrated in the video, you can configure multiple tags in your server-side container to send the same incoming data to different platforms. For example, you can receive Universal Analytics data and forward it to both UA and GA4 properties without adding additional client-side code.
EU-based alternatives like gdpr-server-tracking.eu offer server-side tracking infrastructure on bare metal servers in Finland, operated by EU companies with no US ownership. These solutions provide the same technical benefits while addressing GDPR compliance concerns and often include additional privacy features like parameter filtering and data hashing.
