When it comes to integrating Google Analytics into your website, Google offers two options: Google tags and Google Tag Manager (GTM). If you’re unsure about these code types and their proper implementation on your WordPress website, this blog post provides clarity.

Understanding GTAG (gtag.js)

Discover GTAG (gtag.js), a JavaScript code library provided by Google when you create a new Google Analytics property. By installing this tracking code, you can start monitoring standard events on your website. Additionally, GTAG (gtag.js) is closely linked to Google Ads, expanding its functionalities.

Exploring Google Tag Manager (GTM)

Google Tag Manager (GTM) simplifies tag management on your website by consolidating them in one place through a user-friendly interface. Even without coding knowledge, you can effortlessly add various tracking codes, including Google Analytics tracking, Google Analytics events, Google Ads conversions, remarketing, and even custom codes.

Not limited to Google’s products, it also supports other tracking codes like Facebook Pixel and Hotjar.

Choosing the Right Code

For efficient website traffic tracking, we recommend utilizing Google Tag Manager (GTM). It not only streamlines tag management but also offers the flexibility to incorporate multiple Google services.

On the other hand, if your sole focus is Google Analytics, GTAG (gtag.js) can suffice.

Can Add Both Codes to a Website?

Technically, it is possible, but we strongly advise against it due to the potential for duplicate tracking issues. Using both simultaneously can result in conflicting data and inaccurate reporting.

It is best to utilize Google Tag Manager if you have multiple Google services integrated into your website. This allows for centralized management and avoids any complications that may arise from using both codes concurrently.

Implementing the Code on WordPress

Easily add the code to your WordPress website using plugins designed for hassle-free integration. These plugins eliminate the need for coding expertise. Refer to our detailed article on this matter for step-by-step instructions and recommendations.

Conclusion

Understanding the disparities between Google Tag Manager (GTM) and GTAG (gtag.js) is essential for successfully implementing Google Analytics tracking and other services on your website. Opt for Google Tag Manager (GTM) to efficiently manage your tags, while GTAG (gtag.js) is specifically tailored for Google Analytics.
