Google Tag Manager Server-Side Containers: A Privacy-First Approach to Data Collection

Frequently Asked Questions
Common questions about "Serving up success using Google Tag Manager Server Side Containers edited"
Client-side tag management loads multiple third-party scripts directly on a webpage (often 25+ scripts per page view), while server-side tag management proxies these connections through your own domain, reducing direct browser-to-vendor communication and improving security and privacy.
The key benefits include privacy-first data collection (controlling what data is shared with third parties), improved website performance (reducing scripts from dozens to just one), enhanced data governance (standardizing and enriching data), and better security (reducing risk from third-party scripts).
Server-side tracking significantly improves website performance by reducing the number of scripts loading on each page from potentially dozens to just one, resulting in faster page load times and a better user experience.
Server-side tracking enhances GDPR compliance by giving organizations complete control over what data is shared with third parties, allowing them to redact sensitive information like IP addresses before sharing, and creating a staging environment where data can be filtered according to consent preferences.
Yes, when using Google Cloud Platform for hosting server-side containers, data may still be processed by Google as a third party with potential access via cloud provider subprocessors, which can create GDPR compliance challenges for EU-based organizations.
EU-based solutions like gdpr-server-tracking.eu offer enhanced GDPR compliance through EU-based bare metal servers (hosted in Finland), no third-party access via cloud provider subprocessors, and additional features for hashing and filtering sensitive data, providing a more compliant alternative for organizations concerned about international data transfers.
Migration requires technical expertise but is manageable with proper planning. The process involves setting up a server-side container, configuring data streams, and updating client-side tags to send data to your server instead of directly to vendors, with the benefit of significantly improved privacy and performance.
Yes, you can continue using your existing marketing and analytics tools with server-side tracking. The difference is that data is first sent to your server where you can control, filter, and enhance it before forwarding only necessary information to third-party vendors.
