The Google Tag Manager is a tool that can be used for server-side tracking. It allows website hosts to install various marketing tags on the page without changing the website code. Tags are code snippets that are embedded in the JavaScript or HTML code to collect information.
To use platforms like Google Analytics or Matomo for website traffic analysis, the codes must be inserted into the website. This can become problematic if one is not familiar with the HTML code. Therefore, the Google Tag Manager is particularly a simple solution for laypersons to apply tracking methods. Especially with platforms like WordPress, tracking providers can be easily integrated.

What does the Google Tag Manager measure?

With Google’s Tag Manager, various tracking codes can be integrated into the website. This includes tags used for Google Analytics or Google Ads.

The Tag Manager can record various user behaviors. This includes aspects such as scroll depth, time spent, mouse movement, which elements are clicked, or whether forms are filled out. Additionally, custom tags for conversion tracking and other purposes can also be created.

Google Tag Manager and the GDPR

Even though it initially sounds like Google Tag Manager can access some personal information, it is stated that it complies with the German General Data Protection Regulation (GDPR). This is mainly because the Tag Manager is merely a support tool for implementing certain tracking measures. These, in turn, must be GDPR-compliant. This is the case, for example, with Google Analytics 4 or Matomo.

Setting up Google Tag Manager

The Tag Manager is primarily a management system that is worthwhile in conjunction with analytical tools such as Google Analytics, Google Ads, or Matomo. The free tool is very easy to set up. To do this, an account must be created that is linked to the website that will receive the tags. After that, the Tag Manager can already be downloaded. For this, you need to integrate the provided code as far up as possible in your website.

Subsequently, you can choose the aspects to be analyzed within the Tag Manager itself. The connection with other tools such as Analytics can also be made in Google Tag Manager. The Tag Manager offers various options to collect detailed data for specific campaigns or pages.
