Do you know Google Tag Manager can help you manage cookies and ensure compliance with privacy laws like GDPR and CCPA?
However, the real question is how Google Tag Manager cookies deploy, protect user privacy, and gather essential analytics data without violating regulations.
Unlike traditional methods, GTM cookies aren’t set independently but provide a framework through which you can control various third-party tracking scripts and their behavior based on user consent.
This blog will answer your questions about how GTM cookies are managed, their integration, and the steps you can take to ensure your website is both compliant and optimized for user experience.
Let’s dig together and see how this happens.

What Are Cookies, and Why they are Important?
Cookies are small text files stored on users’ browsers when they visit websites. These files track user behavior, preferences, and other data, which can later be used for analytics, marketing, and personalization.
Analytics cookies: Used to track user behavior (e.g. cookies for Google Analytics).
Marketing cookies: Used for ad targeting or remarketing purposes.
However, due to privacy regulations such as the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA), websites must now obtain user consent before storing or tracking personal information.
How Does Google Tag Manager Work with Cookies?
While Google Tag Manager cookies are not set itself, it enables the deployment of tags (scripts) to create and manage cookies.
Google Tag Manager acts as a container that holds various marketing and analytics tags (such as Google Analytics, Facebook Pixel, etc.).
These tags often rely on cookies to track users, but GTM ensures they only fire based on user consent preferences.
By integrating GTM with Consent Management Platforms (CMPs) like Cookiebot or CookieYes, you can tailor your website’s GTM cookie deployment to meet legal requirements.
Google Consent Mode and GTM
A critical feature for managing GTM cookies is Google Consent Mode. This allows websites to adjust the behavior of their tags based on the user’s cookie consent.
Google Consent Mode ensures that the tags collect only essential data, such as anonymized information for conversion tracking until a user gives their full consent.
It also ensures that tags for advertising or advanced analytics do not fire until the appropriate consent is obtained.
|
For Example! If a user declines tracking cookies, Consent Mode ensures that the data collected is aggregated and anonymized to still provide some analytics without violating privacy rules. When users opt-in to cookies, the Google Tag Manager cookies linked to specific marketing and analytics tags resume full functionality. |
Implementing Google Consent Mode in GTM
To manage Google Tag Manager cookies effectively, you’ll need to configure Consent Mode within GTM.
This starts with setting up a Consent Initialization trigger, which runs before any other tags, ensuring that the user’s consent is processed before any cookies are set. This helps to align with privacy laws like GDPR and CCPA.
- Set up Consent Mode:
You’ll need to create a Consent Mode tag in GTM that respects user preferences and ensures GTM cookies are only set when allowed.
- Use Consent Management Platforms (CMPs):
CMPs offer pre-built templates within GTM that manage cookies based on user consent.
These platforms generate cookie banners that allow users to opt into different categories of cookies, and GTM ensures that no Google Tag Manager cookies are set without their consent.
- Managing Third-Party Cookies:
Many third-party tags rely on cookies to track users. GTM makes it easy to block these cookies until the user consents, ensuring compliance with privacy laws.
Consent triggers within GTM allow you to fire certain tags based on whether the user has opted into categories like analytics or marketing cookies.
How to Block Cookies with Google Tag Manager
Blocking Google Tag Manager cookies without user consent is a critical step in adhering to regulations like GDPR and CCPA.
With GTM, there are two ways to ensure GTM cookies are not set prematurely:
- Block All Tags Until Consent Is Given:
GTM can block any non-essential tags (and their cookies) from firing until the user consents via the cookie consent banner.
- Conditional Firing Based on Consent:
GTM allows you to fire specific tags based on the user’s consent level.
For instance, if a user consents to analytics cookies but not marketing cookies, GTM will block all marketing-related Google Tag Manager cookies while allowing essential or analytics-related tags to function.

Tip! CMPs like CookieYes or Cookiebot offer tag templates specifically for GTM, making it easier to set up cookie-blocking rules. These templates automatically handle user preferences, making it simpler to ensure compliance across different regions. |
Best Practices for Managing Cookies in Google Tag Manager
Some of the best practices you can adopt to manage Google Tag Manager cookies are as below:
- Use Consent Mode:
Always implement Consent Mode when using GTM cookies to ensure that your tags respect user privacy. This feature helps adjust the behavior of your tags based on the type of consent users provide.
- Integrate a CMP:
A Consent Management Platform is essential for GDPR and CCPA compliance. CMPs like CookieYes and Cookiebot provide seamless integration with GTM, allowing you to manage cookie consent across your website.
- Regularly Update Cookie Policies:
Make sure that your website’s cookie policies are up to date and that users are informed about the types of cookies being used. The consent banner should also be easy to understand and provide users with the option to change their preferences at any time.
- Test and Debug Cookie Management:
Regularly test your GTM implementation to ensure that cookies are being managed correctly. Use Goole Tag Manager tools like GTM’s Preview mode to check that cookies are blocked until consent is provided and that only the allowed cookies are set.
- Be Transparent:
Clearly explain to users how cookies are being used on your website. Make your privacy and cookie policies easy to access and provide detailed information on how users can opt in or out of cookie tracking.
Conclusion
Google Tag Manager offers a robust and flexible way to manage cookies, especially when integrated with tools like Google Consent Mode and CMPs.
Setting up proper consent triggers and ensuring compliance with privacy laws like GDPR and CCPA allows you to manage user data responsibly while still collecting essential information for analytics and marketing.
Managing cookies in GTM involves setting up consent mechanisms, controlling tag behavior based on user consent, and ensuring that third-party scripts comply with privacy regulations.
When done correctly, GTM allows you to balance data collection needs with user privacy, providing a seamless and compliant experience for both your website and its visitors.
