Using One Server-Side GTM Container for Multiple Domains: A Cost-Effective Solution

facebook-pixelgoogle-analyticsserver-sidegdprprivacyadvanced
4.5/5The video provides comprehensive, step-by-step instructions for implementing server-side tracking across multiple domains using a single GTM container. The presenter clearly explains the technical concepts, demonstrates the implementation process, and addresses different scenarios that users might encounter. While the production quality is good, the video could benefit from more visual aids to illustrate the data flow between domains and the server container.
Server Side Tracking For Multiple Domains (w/GTM)

In this comprehensive tutorial, Cedric from Vertex Marketing Agency demonstrates how to efficiently track multiple domains using a single Google Tag Manager server-side container. The video is particularly valuable for businesses managing several domains who want to implement server-side tracking without duplicating costs or infrastructure. The tutorial walks through the complete process of configuring your web containers to send data to a shared server-side container while maintaining first-party context for each domain. Cedric explains how to create custom subdomains for each website in your Google Cloud project, ensuring proper first-party data collection despite using a single server infrastructure. Key points covered include setting up web container tags with domain-specific parameters, creating custom subdomains in Google Cloud, configuring your server container settings to recognize multiple domains, and implementing triggers that direct data to the appropriate measurement IDs or pixels based on the source domain. A particularly useful technique demonstrated is the addition of an "identify_source" parameter that helps the server container distinguish between events coming from different domains. This allows for proper routing of data to domain-specific analytics properties or advertising platforms, even when sharing server infrastructure. The video also addresses different scenarios, such as businesses using separate measurement IDs and pixels for different domains versus those using the same tracking IDs across all properties, providing flexible solutions for various setups. From our perspective at gdpr-server-tracking.eu, this video offers excellent technical guidance, but viewers should also consider the GDPR implications of server-side tracking. While the tutorial focuses on cost efficiency by sharing a Google Cloud project, our EU-based server-side GTM hosting provides additional benefits from both compliance and cost perspectives. Our solution offers bare metal hosting in Finland with EU-based ownership, eliminating third-party access concerns present in cloud environments. Users can implement the same multi-domain techniques demonstrated in the video on our platform, while gaining enhanced data protection features like parameter filtering and hashing capabilities - all at competitive pricing without the variable costs of cloud solutions. For businesses concerned about international data transfers or seeking more predictable server-side tracking costs, our platform provides an excellent alternative to the Google Cloud implementation shown in the tutorial.

Frequently Asked Questions

Common questions about "Server Side Tracking For Multiple Domains (w/GTM)"

Using one server-side container for multiple domains helps save on costs by utilizing a single Google Cloud project subscription rather than paying for multiple instances. It also keeps your tracking infrastructure more organized and centralized, making maintenance and updates more efficient.

First, access your Google Cloud project through GTM, navigate to App Engine settings, and add each custom subdomain (e.g., ss.yourdomain.com). Then create DNS records with your provider, add these URLs to your server container settings, and ensure your web containers send data to their respective subdomains.

The 'identify_source' parameter is a custom field added to events that helps the server container distinguish between data coming from different domains. This parameter allows you to create specific triggers that direct data to the appropriate measurement IDs or pixels based on the source domain.

No, you don't necessarily need different measurement IDs. If you use the same measurement ID or pixel across all domains, you can simply create a trigger based on the client name without checking the source domain. However, most businesses prefer separate measurement IDs for different regional domains to analyze performance independently.

When using server-side tracking across multiple domains, GDPR compliance becomes more complex as you're centralizing data collection from different sources. Using Google Cloud hosting means your data may be processed outside the EU, creating potential compliance risks that could be mitigated by using EU-based server hosting with proper data protection measures.

EU-based hosting like gdpr-server-tracking.eu provides better GDPR compliance through servers physically located in the EU (Finland) with EU-based ownership, eliminating concerns about international data transfers. Additionally, it offers more predictable pricing compared to variable cloud costs, along with enhanced privacy features like parameter filtering and hashing capabilities.

Yes, the same multi-domain tracking technique works with EU-based server hosting solutions. You would still create custom subdomains for each website, add identifying parameters to your events, and set up appropriate triggers in your server container, but with the added benefit of improved data privacy compliance.

If you already have server-side tracking working for one domain, you can add more domains by creating additional custom subdomains in your Google Cloud project, adding these URLs to your server container settings, implementing the 'identify_source' parameter in your web containers, and creating domain-specific triggers in your server container.
