What is GTM Server-Side?
Google Tag Manager Server-Side (GTM SS) is an advanced tag management solution that shifts much of the data processing from the user’s browser to a server. Unlike the standard Google Tag Manager, which operates entirely in the client’s browser, GTM SS allows for data processing and storage on a server. This significantly improves performance, security, and privacy.

Unlock the full potential. Benefits of implementing GTM Server-Side
Faster page load times
By shifting the processing load from the browser to the server, this technology reduces the amount of JavaScript and HTTP requests. As a result, it speeds up page load times, improves caching efficiency, and streamlines data transmission.
Reduced data loss
In standard GTM, where tags run in the user's browser, ad blockers and browser extensions can interfere with tracking. GTM Server-Side moves data processing to the server, where it’s less vulnerable to such blocks - ensuring more complete and accurate data collection.

Enhanced data security
Processing data in a server environment significantly increases data security. It also gives you 100% control over what information is sent to third-party providers (like Facebook, Google, or TikTok). For example, you can prevent user IP addresses from being sent to Google Analytics.

Stages of GTM Server-Side Implementation
What should a model implementation look like?
When a user visits the website, they should see a popup message where they can either consent to or decline the use of cookies. If consent is given, cookies activate the analytical tools (e.g., Google Analytics 4, Facebook) implemented on the site, which rely on cookies. However, if consent is not granted—or until it is obtained—it must be assumed that consent has not been given, and tracking cookies must not be placed.

Step 1
Free audit of the current configuration
If you already have the GA4 tool implemented within your website structure, our cooperation begins with a comprehensive evaluation of your Google Analytics configuration and other tools. Based on this assessment, we identify what changes are advisable from our perspective.

We then prepare a strategy for executing specific areas of the implementation.
Step 2
Selection of server architecture and implementation plan
We choose the appropriate method for hosting the server container (e.g., Google Cloud, Stape.io) and create a detailed migration plan. We take into account technological requirements, security, and solution scalability.
Step 3
Server-Side environment configuration
We set up and configure the GTM Server-Side environment, including DNS, security protocols (SSL), traffic filtering, and user data protection.
Step 4
Migration of tags and scripts from the browser to the server
We transfer key tags (e.g., Google Analytics, Meta, TikTok) from the browser to the server container, minimizing the number of scripts loading on the user’s side.
Step 5
Testing and data transmission verification
We thoroughly test the functionality and quality of the data. We check compliance with the privacy policy, conversion tagging, and the operation of marketing tools.
Step 6
Implementation documentation
After assessing the quality of the data collected in Google Analytics 4, we prepare detailed technical and operational documentation—describing the server configuration, tags, rules, and changes to the website code.

Frequently Asked Questions (FAQ)
Will implementing Google Tag Manager Server-Side affect the speed of my website?
chevron down icon
Yes, implementing Google Tag Manager Server-Side typically has a positive impact on website loading speed. Moving tag processing from the user's browser to the server reduces the amount of JavaScript that needs to be executed on the client side. This decreases the time required to load the page, as the browser has fewer tasks to perform during initialization. Additionally, a lower number of HTTP requests sent directly from the browser to external servers also contributes to faster content loading. Thanks to these improvements, GTM Server-Side can significantly enhance site performance, resulting in a better user experience and potentially improved search engine rankings.
How long does the Google Tag Manager Server-Side implementation take?
chevron down icon
The implementation time for Google Tag Manager Server-Side depends on several factors, such as the complexity of the existing infrastructure, the number and type of tags to be migrated, and the experience of the team. Typically, the process includes several stages:
→ Planning and analysis: Assessing needs and preparing an implementation plan.
→ Environment configuration: Setting up the server, security measures, and domain.
→ Tag migration: Moving tags from the standard GTM to the server-side version.
→ Testing and optimization: Verifying the system’s operation and fine-tuning it.
What are the main differences between standard Google Tag Manager and Google Tag Manager Server-Side?
chevron down icon
The key differences between standard Google Tag Manager (GTM) and Google Tag Manager Server-Side involve how data is processed and stored. In standard GTM, tags are triggered and processed directly in the user's browser, which can affect page performance and be vulnerable to content blockers. The server-side version shifts tag processing to the server, reducing the amount of JavaScript loaded in the browser, increasing page load speed, and improving data security and privacy. Additionally, the server-side setup provides greater control over data, reducing the risk of data leakage.
