Why has Google made gtag.js the default method of implementing Google Analytics? Google may be missing the mark when it comes to empowering businesses to harness the full potential of their analytics stack.
1. Flexibility for Tracking Customisation
GTM makes it easy to set up and manage various custom tracking events without touching your site’s code directly. With gtag.js, each new event often requires additional development work, making customisation more rigid and resource heavy.
2. Streamlined Tag Management
GTM centralises your tag management, not just for GA4 but for all tracking and marketing tags. With GTM, you can add, modify, and update tags as needed, often without requiring developer support. In contrast, with gtag.js, each update requires a manual code change, slowing down deployment and increasing the risk of errors.
3. Enhanced Debugging Capabilities
GTM offers a built-in debug mode, allowing you to test tags and triggers in a live environment without affecting your data collection. With gtag.js, troubleshooting tracking issues becomes more complicated, often involving manual testing and code debugging.
4. Efficient Consent Management and Compliance
Consent management for GDPR, CCPA, and other regulations is easier to handle in GTM, especially with built-in features for integrating consent tags. While gtag.js supports basic consent settings, GTM’s flexibility allows for more refined configurations, ensuring that your site’s tracking remains compliant with data privacy laws.
5. Agility with Version Control
GTM provides version control, enabling you to roll back to a previous version of your container if an issue arises. This ia invaluable when testing new configurations. Unfortunately, gtag.js lacks this feature, making it challenging to revert changes without affecting live tracking.
6. Reduced Developer Dependency
With GTM, marketing and analytics teams can manage tags and tracking setups independently, reducing the need to engage developers for every change. This is particularly useful for agile marketing teams that need fast turnaround times for tracking changes. By contrast, gtag.js creates more dependency on developers for even minor tracking adjustments.
7. Better Data Quality and Custom Parameters
Implementing GA4 through GTM means that you can send custom parameters with each event, allowing for richer data in your reports. While gtag.js supports custom parameters, GTM’s interface makes it easier to set these up and manage them, contributing to higher-quality data collection.
Gtag.js may offer a simpler route for basic implementations, Google Tag Manager delivers the agility, control, and precision that modern analytics requires.
