Server-side Tagging in Google Tag Manager: Comprehensive Webinar Overview

Frequently Asked Questions
Common questions about "Server-side Tagging in Google Tag Manager - Webinar (North America)"
Server-side tagging in GTM creates a controlled environment between your website and third-party vendors, allowing you to process data on a server you control before sending it to analytics and marketing platforms. This gives you unprecedented control over data collection, reduces client-side bloat, and enhances security and privacy.
Google's recommended production setup costs approximately $120 USD monthly for three App Engine flexible instances. Costs can increase with higher traffic volumes, more complex payloads, or performance-heavy API calls.
Key benefits include reduced client-side bloat by eliminating third-party JavaScript libraries, enhanced data privacy through better PII management, improved security by minimizing cookie leaks, and the ability to leverage cloud platform capabilities for processing data.
Server-side tagging can enhance GDPR compliance by giving you more control over what data is shared with third parties, allowing you to filter out PII before it leaves your server, and providing better cookie management. However, where your server is hosted matters for data residency requirements.
While Google currently only officially supports GCP deployment, EU-based hosting solutions like gdpr-server-tracking.eu offer alternatives with guaranteed EU data residency, bare metal hosting without cloud provider subprocessors, and enhanced privacy features specifically designed for GDPR compliance.
Migration involves setting up a server container, creating appropriate clients to receive data from your website, configuring tags in the server container to process and forward that data, and updating your website tags to send data to your server endpoint instead of directly to vendors.
Major concerns include the potential to circumvent ad blockers and content blockers, opacity of data collection making it difficult for users to audit, and the lack of built-in consent management. These issues require careful ethical consideration when implementing server-side tagging.
EU-based hosting solutions like ours ensure data remains within EU jurisdiction with servers physically located in Finland, eliminating concerns about data transfers to non-EU countries. This provides stronger GDPR compliance compared to US-based cloud providers and offers additional privacy features specifically designed for EU regulations.
