In modern digital marketing, speed and measurement accuracy are critical. That’s why Google Tag Manager 360 (GTM 360) has become a key component of the Google Marketing Platform (GMP) — a tool that enables companies to centrally manage tags, analytics, and event tracking without relying on developers at every step.

In 2025, Google Tag Manager remains an indispensable tool for analytics agencies and brands seeking complete control over their data.

What is Google Tag Manager 360

Google Tag Manager 360 is the enterprise version of the popular GTM, designed for large organizations that need to manage hundreds of websites, apps, and containers within a single ecosystem.

It enables teams to:

• Centrally manage all tags — including analytics, advertising pixels, and custom tracking scripts;
• Delegate access and permissions across internal teams and clients;
• Automatically deploy updates through controlled testing environments;
• Integrate seamlessly with the full GMP 360 suite — including Analytics 360, Display & Video 360, and Campaign Manager 360.

What’s New in Tag Manager 360 in 2025

In 2025, Google continues to advance Tag Manager 360, the enterprise version of GTM that remains the central tool for tag management within the Google Marketing Platform ecosystem. The key focus areas this year are automation, privacy compliance, and enhanced stability of the server-side infrastructure.

1. Consent Mode v2 Support

Google has officially updated Consent Mode to version v2, and Tag Manager 360 is now fully compatible with the new framework. Consent Mode v2 allows GTM to transmit user consent states (such as ad_storage, analytics_storage, ad_user_data, and ad_personalization) directly to all tags within the container.

This update enables brands and agencies to stay compliant with GDPR, CCPA, and CPRA requirements — without manually editing website code, making privacy-friendly tracking easier and more efficient.

2. Server-Side Tagging

Server-Side Tagging remains one of the core areas of development for GTM 360 in 2025. Google now supports deploying server containers either in Google Cloud Run or within an organization’s own infrastructure.

This approach significantly reduces event transmission latency, improves control over user data, and helps businesses stay aligned with modern privacy and data protection standards.

3. New Consent Management Parameters in GTM

In 2025, Google updated the GTM Consent configuration, introducing the ability to override consent states (Set consent mode override) for individual tags or entire containers. This improvement gives analysts and agencies greater flexibility in managing which tags are activated under different user interaction scenarios — helping ensure compliance while maintaining accurate data collection.

4. New Integrations within GMP 360

Tag Manager 360 now features enhanced integration with Display & Video 360 and Campaign Manager 360, simplifying conversion signal transmission and expanding campaign tracking capabilities. This update enables agencies and data teams to configure and manage event tracking directly for media platforms — all without modifying website code, streamlining operations, and improving measurement consistency across the Google Marketing Platform ecosystem.
