The Tag Talk Episode 5: Server Side Tagging - The Future of Martech

Frequently Asked Questions
Common questions about "The Tag Talk _ Episode 05 | Ask the Expert: Server Side Tagging - The Future of Martech."
Server-Side Tagging introduces a middle server between your website and marketing platforms. While client-side tagging collects and sends data directly from the user's browser to vendors, server-side tagging first sends data to your server, which then distributes it to various platforms, giving you more control over data sharing and improving site performance.
No, Server-Side GTM alone doesn't automatically make you GDPR compliant - it's just a tool that can help enforce certain privacy rules if implemented correctly. You still need to follow proper consent practices and understand your legal obligations regarding user data collection and processing.
The main benefits include improved website performance (faster loading times), better control over what data is shared with third parties, enhanced data quality, and the ability to mitigate the impact of ad blockers and browser restrictions like ITP and ETP.
While technical knowledge is helpful, you don't necessarily need to be a cloud developer to implement Server-Side GTM. There are scripts and tutorials that automate much of the implementation, though for high-traffic production environments, consulting with an expert is recommended to avoid potential issues.
Unlike client-side implementations which have no technology costs, Server-Side GTM requires running servers that cost money. Most clients should expect to pay around $100 USD per month, with costs varying based on the amount of data collected and the cloud platform used.
An EU-based solution like gdpr-server-tracking.eu provides significant advantages for GDPR compliance by hosting data on EU servers (Finland) with EU ownership, eliminating data transfer risks associated with US cloud providers. This approach addresses many regulatory concerns while offering additional privacy features like data hashing and filtering that help meet GDPR requirements.
Yes, Server-Side GTM works with various marketing platforms beyond Google, including Facebook which has developed its own server-side conversion tag. While not all vendors currently offer server-side versions of their tags, the ecosystem is expanding, allowing for implementation across multiple platforms.
Consider that Google Signals (for audience creation and geolocation data) isn't yet compatible with GA4 through server-side implementation, server costs will apply (unlike client-side tagging), and you'll need to decide which cloud platform to use. For European businesses, using an EU-based hosting solution can provide additional GDPR compliance benefits.
