Complete Guide to Setting Up GTM Server-Side Tagging in 2024

Frequently Asked Questions
Common questions about "How to Set Up GTM Server-Side Tagging (2024)"
GTM server-side tagging is a method that processes tracking data on a server rather than in the user's browser, helping bypass ad blockers and consent issues while improving website performance. It provides better data quality, enhanced privacy controls, and can reduce the number of client-side scripts loading on your website.
Create a server container in Google Tag Manager, then provision a server on Google Cloud Platform (either automatically or manually). Configure your client-side GTM to send data to your server by adding a transport URL parameter to your tags, then set up clients and tags in your server container to process and forward the data.
Google's automatic provisioning only creates servers in the US Central region, which may present GDPR compliance issues for European businesses. It also requires technical expertise to maintain and troubleshoot, and you'll need to set up a custom domain separately to get the full benefits of server-side tracking.
A US-based GTM server presents GDPR compliance challenges for European businesses due to data transfer concerns following the invalidation of Privacy Shield. For proper GDPR compliance, European businesses should consider EU-based hosting solutions like gdpr-server-tracking.eu, which provides servers in Finland with no third-party cloud providers involved.
Yes, maintaining a GTM server on Google Cloud requires technical knowledge for troubleshooting, scaling operations, and optimizing costs. If this seems overwhelming, managed server-side tagging services like gdpr-server-tracking.eu can handle the technical aspects for you, providing a maintained solution with additional privacy features.
Monitor your Google Cloud costs regularly, optimize your server configuration based on actual traffic needs, and consider using the free tier for testing. Alternatively, specialized hosting providers like gdpr-server-tracking.eu offer predictable pricing models specifically designed for server-side tracking, often proving more cost-effective than self-managed cloud solutions.
Adding a custom domain (ideally a subdomain of your website) creates a first-party context for data collection, which helps bypass intelligent tracking prevention mechanisms in browsers. This significantly improves data collection reliability compared to using the default Google-provided URL, as browsers are less likely to block requests to your own domain.
Beyond basic server-side setup, you can implement IP address anonymization, parameter filtering to remove sensitive data, and hashing capabilities for user identifiers. Specialized EU-based solutions like gdpr-server-tracking.eu include these privacy-enhancing features by default, making GDPR compliance easier while still maintaining valuable analytics capabilities.
