Google Tag Manager: Tracking Without Developer Dependency
Asking development to add a tracking pixel every time — that costs time and money. Google Tag Manager solves this problem: once installed, you manage all tags through a web interface. New tags, changes, and deletions go live without touching the website's source code.
How Google Tag Manager Works
Container. GTM works with containers. A container is a code snippet installed once on your website. All tags are managed within this container.
Tags. A tag is a third-party code snippet: Google Analytics, Facebook Pixel, LinkedIn Insight Tag, conversion tracking. GTM comes with templates for the most common tags.
Triggers. Triggers define when a tag fires: on page view, on button click, on scroll depth, or on form submission.
Variables. Variables provide dynamic values to tags: page title, URL, click text, or custom data layer values.
Integrating GTM in Drupal
The Drupal module "Google Tag Manager" automatically adds the GTM container code to the header and body of your website. Integration with a consent management tool (e.g., Cookiebot or Usercentrics) ensures that tags only load after consent — GDPR-compliant.
For advanced requirements, arocom uses the data layer: a JavaScript data layer that passes Drupal-specific information (content type, taxonomy, user role) to GTM.

What is Google Tag Manager?
A tag management system by Google that manages marketing and analytics tags through a web interface — without code changes to the website. Free to use.
Is Google Tag Manager GDPR-compliant?
GTM itself does not set cookies. The tags you embed through GTM require consent. The combination of GTM and a consent management tool is GDPR-compliant.
Do I need GTM for Google Analytics?
No, Google Analytics can also be embedded directly. GTM makes management easier — especially when you use multiple tracking tools and regularly adjust tags.
