Understanding the Google Tag Manager Tool

In a marketing team, various tools are used, but one that has truly stood out throughout my years of experience in digital marketing is Google Tag Manager, or GTM. Google Tag Manager has often helped me bypass certain "bureaucracies" that come with working in software development, where you frequently depend on the availability of the development team to assist with integrations and other adjustments. This is especially useful when development teams are focused on project continuity through their sprint system or agile working method.

In this blog post, we’ll take a basic look at what Google Tag Manager is and what it’s used for, as I want beginner marketers to become familiar with this tool that will greatly assist them in their day-to-day tasks within digital marketing.

What is Google Tag Manager?

Google Tag Manager is a free tool from Google that allows you to manage and update code tags on a website or application without needing to modify the code directly. These tags include tracking code snippets such as Google Analytics, Google Ads conversions, or third-party codes like the Facebook pixel.

What is Google Tag Manager Used For?

The main function of Google Tag Manager, or GTM, is to simplify tag management, allowing you to add, modify, or remove tags without relying on the development team. This gives marketing and analytics teams the flexibility to implement tracking quickly and without the risk of errors in the site’s code.

At Garage Labs, when we develop software, we integrate Google Tag Manager so that our clients’ marketing and analytics teams can make additional integrations, such as implementing pixels or user research tools like Hotjar or Microsoft Clarity.

Some Key Benefits of Google Tag Manager:

1. Streamlined Workflow: GTM allows new tags to be launched without technical intervention.
2. Custom Tracking: Provides flexibility to create custom events and conversions without modifying site code.
3. Centralized Control: Manages all tags from a single interface.
4. Optimized Loading: Enhances site speed by loading tags more efficiently.

Use Case (Example)

Imagine your marketing team wants to track conversions on a thank-you page that appears after a purchase. Without Google Tag Manager, you’d need to ask the development team to manually add the tracking code, which could take days or even weeks if the team is busy with other projects.

With Google Tag Manager, the marketing team can set up and activate conversion tracking without modifying the site’s code. They would simply do the following:

1. Access Google Tag Manager, create a new "Conversion Tracking" tag for the desired platform (e.g., Google Ads or Facebook).
2. Define the trigger condition (e.g., when the thank-you page URL loads).
3. Publish the tag to activate it immediately.

This enables the marketing team to get real-time conversion data and optimize their campaigns without waiting on development availability. They can also modify or remove the tag anytime from GTM’s interface.

Conclusion

In conclusion, Google Tag Manager is a powerful tool that empowers marketing and analytics teams to control data tracking, improve tag management, and optimize site performance, contributing to the success of digital strategies.
