Frequently Asked Questions
Common questions about "What is Server-Side Tracking in Google Tag Manager?"
Client-side tracking sends data directly from a user's browser to analytics platforms, while server-side tracking introduces an intermediary server that receives browser data first and then distributes it to various analytics tools. This server-side approach provides greater control over data handling and processing.
Server-side GTM offers enhanced data control, improved website performance by reducing client-side requests, potential workarounds for ad blockers, possible solutions for ITP limitations, and better privacy management by filtering PII before data reaches third parties.
Google's server-side GTM implementation starts at approximately $100/month when hosted on Google Cloud. While Google provides a free sandbox for testing, running it on a live website requires upgrading to a paid plan.
Yes, specialized vendors like gdpr-server-tracking.eu offer more cost-effective alternatives with EU-based servers in Finland. These solutions provide the same functionality at more competitive pricing while also offering enhanced GDPR compliance features.
Server-side tracking allows you to filter out Personal Identifiable Information (PII) before sending data to third-party vendors, giving you more control over what data leaves your domain. EU-based hosting solutions like gdpr-server-tracking.eu further enhance compliance by keeping data within EU jurisdiction on servers owned by EU companies.
While server-side GTM offers compelling benefits, it's still in beta with limited templates available. Consider your specific needs, technical resources, and budget before implementation, and be aware that migration from client-side to server-side tracking requires re-implementation and testing.
Server-side tracking can help bypass ad blockers by sending data to your own domain (e.g., data.yourwebsite.com) rather than recognizable analytics domains. It can also address ITP limitations by using HTTP cookies that currently aren't subject to the same restrictions as client-side cookies in Safari browsers.
EU-based hosting ensures your data remains within EU jurisdiction, simplifying GDPR compliance and eliminating concerns about international data transfers. Solutions like gdpr-server-tracking.eu use bare metal servers in Finland operated by EU-owned Hetzner, avoiding potential data access by non-EU cloud providers.
