The Google Tag / gtag.js – A comprehensive guide

In the digital age, everything revolves around data. However, the proper way to collect and analyze this data can be complex. Although gtag is touted as a simple approach to connecting your website to Google services, there are concerns about its efficiency and precision, particularly among professional circles. In this article, we look at the advantages and disadvantages of gtag compared to other methods.

What is the “gtag”?
The “gtag”, also known as “Google Global Site Tag”, is a Javascript framework developed by Google. Its main purpose is to collect data from websites and send it to various Google services such as Google Analytics, Ads, and Conversion Tracking. Think of it as the bridge that connects your website to Google services.

How and why do you use the gtag?
The main reason for using gtag is to simplify tracking. With just one snippet of code, you can use multiple Google services at the same time, saving time and reducing the complexity of setting up tracking tools. This may be attractive to beginners, but subject matter experts often prefer Google Tag Manager (GTM), which allows for more complex integrations and greater control.

How do you implement the gtag?
The implementation is straightforward:

Create a Google Analytics account.
In the account settings, you will find the required “tracking code” under “Tracking Information”.
Paste this code into the head of your website.
Voila! Your website is now connected to Google services. However, it is important to note that this only represents the basic integration. Additional steps are required to fully track events or conversions. In addition, it is essential to comply with privacy policies and cookie consent solutions to use the gtag legally correctly.

Advantages
Consistency: Utilizing a unified code streamlines administration and minimizes errors.
Flexibility: Additional Google services can be seamlessly incorporated without the need to integrate entirely new code.
Performance: The gtag is designed for optimized speed and reliability, ensuring minimal impact on website operations.

Disadvantages
Data Protection : Adhering to data protection regulations is crucial, necessitating ongoing adaptation of the gtag.
Limited Customization : The default code provided is uneditable, restricting customization options.
Lack of Granular Control : In comparison to GTM, gtag offers less depth and precision.
Complex Implementations : Gtag may encounter limitations when dealing with highly individual or complex pages.
Limited Debugging : Troubleshooting can be more challenging due to fewer built-in tools than GTM.
Lack of Professional Usage : Professional digital marketers and analysts predominantly favor GTM over direct gtag implementation.

Comparison to GTM and GA4
While gtag provides a direct link to Google services, GTM allows for granular control and event tracking, making it especially appealing for intricate websites. Technically proficient individuals typically opt for GTM for more precise and effective data integration.
