Privacy compliance is no longer optional. With regulations such as GDPR and CCPA in place, websites must prevent analytics and marketing scripts from firing unless users explicitly grant consent. One of the most reliable ways to support this requirement is by integrating a reliable Consent Management Platform with Google Tag Manager (GTM).
This article explains, in practical terms, how Termly and GTM work together to control tracking behavior and help prevent unauthorized data collection.
Why Consent-Based Tag Firing Matters
A compliant setup helps align tracking activity with user permission, allowing scripts to run only after consent is provided and according to selected preferences.
- Violating GDPR and CCPA regulations
- Tracking users before consent is granted
- Firing analytics or advertising scripts illegally
- Exposing the business to legal and financial penalties
The Role of Each Tool
Termly: Consent Management Platform (CMP)
Termly is responsible for managing user consent. It:
- Displays the cookie consent banner
- Allows users to accept, reject, or customize cookies
- Stores the user’s consent preferences
- Communicates consent status to Google Tag Manager
In short, Termly decides what is allowed.
Google Tag Manager (GTM)
Google Tag Manager controls the execution of tracking scripts. It:
- Loads analytics, advertising, and marketing tags
- Blocks or fires tags based on consent data
- Responds dynamically when user consent changes
GTM decides when scripts can run.
How the Integration Works
When Termly and GTM are properly connected, they create a system where no non-essential tracking fires before consent.
The integration relies on two critical components.
1. Termly Consent Logic Inside GTM
GTM must be able to interpret Termly’s consent signals. This is achieved by adding a Termly consent template within Google Tag Manager.
Once implemented:
- GTM understands Termly’s consent categories (analytics, advertising, functionality, etc.)
- Tags can be assigned to specific consent types
- GTM knows which scripts must remain blocked until permission is granted
This creates a shared “language” between Termly and GTM.
2. Consent Update Events Triggered by Termly
When a user interacts with the cookie banner, by clicking “Accept,” “Reject,” or updating preferences, Termly sends a key event to GTM:
userPrefUpdate
This event tells GTM:
The user has submitted consent choices. Re-evaluate which tags are allowed to fire.
At this point, GTM immediately checks every tag against the user’s selected preferences.
How Tags Are Controlled by Consent Categories
Each tag in Google Tag Manager is mapped to a consent category, such as:
| Analytics | Google Analytics |
| Advertising | Google Ads, Meta Pixel |
| Functionality | chat tools, embedded services |
| Essential | security, consent management |
This mapping supports compliance by aligning each tag’s behavior with the user’s selected consent preferences:
- If analytics consent is not granted, analytics tags remain blocked
- If advertising consent is granted, ad pixels can begin firing
- Essential scripts run regardless of consent
No tag fires unless its category has been explicitly approved.
When Google Tag Manager Evaluates Consent
GTM checks consent at two critical moments.
1. Initial Page Load
As soon as the page loads, GTM asks:
Has this user already given consent?
- Yes: Only allowed tags fire
- No: All non-essential tags remain blocked
This prevents tracking before consent, even for returning users.
2. After the User Updates Consent
When the user saves preferences, Termly triggers:
consentSaveDone
This event instructs GTM to:
Re-evaluate consent immediately and fire newly allowed tags.
As a result, analytics or advertising tags can activate instantly, without requiring a page refresh, once consent is granted.
The Result: Consent-Driven, Regulation-Ready Tracking
When Termly and GTM are configured correctly, the result is a clean, regulation-ready setup that supports responsible data collection:
- No tracking before consent
- Automated handling of user preferences
- Real-time tag activation after approval
- Alignment with GDPR and CCPA requirements
- Reduced legal and compliance risk
This approach helps protect user privacy while reducing regulatory exposure for the business.
Conclusion
Integrating Termly with Google Tag Manager creates a consent-driven tracking framework that supports modern privacy requirements. Termly captures and stores user preferences, while GTM applies those choices at the technical level, so scripts run only when they are permitted.
For organizations focused on privacy compliance and data integrity, this integration has become a foundational component of modern web tracking.
