GTM allows you to easily make changes and add various tags, triggers, and variables on your dedicated website. Also, they are responsible for firing the defied trigger at the right time. 
  • Data collection:  Google Tag Manager uses a management system to facilitate the sending of tracking of different types of data to various platforms including GA4 and many more analytics tools. Google Tag Manager does not store or analyze the data on its own. Also, Google Tag Manager guarantees to send data which is based on the tags and triggers.

Google Analytics:

Google Analytics tags: Set up GA4 tag manager because it allows you to create events in Google Analytics. Using this tag type, you can send several types of data to Google Analytics, including page views, events, transactions, social interactions, as well as custom timings.

Use Google Analytics GA4 Event tag so you can track thousands of different actions that someone may take, like how many people scrolled down through a page, how many people viewed a page, how many people clicked on a button, how many submitted forms, purchased a product, and much more. You will gain a lot more insight into what your users are actually doing on your website or application by tracking these events.

In Google Tag Manager’s left panel, click Tags → New button → Tag Configuration Google Analytics → Analytics: GA4 Event.

Google Ads conversion tracking: Conversion tracking is a tag that allows you to forward any conversion data to Google Ads. You can use it to measure users’ different actions on your website, like filling up a form, making a purchase, or signing up, and then correlate them back to one of your Google Ads campaigns.

However, you need to include a conversion ID and conversion label from a website conversion action that should have been configured beforehand in your Google Ads account. This will ensure proper conversion data reporting against the correct campaign and also ad group. Another related feature is the conversion linker, which helps connect your website’s conversion data with the Google Ad campaigns that originated traffic.

A conversion linker allows you to have more comprehensive insight into how your Google Ads campaigns are performing and make data-driven decisions that can optimize ad spend.

What are triggers, and how do you configure them?

A trigger in Google Tag Manager is an event or condition that will fire or execute a tag. A trigger determines when and how a tag will be triggered, allowing you to define the exact conditions under which the tag should send data to Google Analytics. Some common examples of triggers are page views, clicks, as well as form submissions.

To build a trigger group:

  • Select Triggers  New.
  • Select Trigger Configuration and choose Trigger Group.
  • Select the two or more triggers from your container.
  • Click Add.
  • Optional: If you want to force multiple instances of the same trigger, click again and select the trigger. You do the same thing for however many times you want that same event to happen before the trigger group fires.
  • Click Save.

How to use variables for dynamic tracking?

The main aim of variables is to capture and store values whenever a user interacts with an application or a website in real-time. Variables store different information, such as page URLs, user IDs, or click events. They can also be used to determine the condition of the trigger fire, and you can set the trigger to activate only when specific variables meet certain criteria.

For example, whenever a person or a customer tries to click on a button that contains a specific text, the trigger gets activated.  Also, variables are responsible for sending the data to third-party measurement and analytics tools.

Types of variables

There are two types of variables. Let us discuss them:

Built-in variables: Built-in variables are predefined variables that users can use without any extra setups or coding. They are designed to track needs and streamline the data collection process.

Using the built-in variable user interface, users can easily track and analyze tasks. It is considered one of the most effective tools for website and application analytics that doesn’t require extensive technical knowledge. 

User-defined variable: User-defined variables are custom variables that a user can create to custom-capture specific data points not covered by the in-built variables. This self-sufficiency suggests that businesses and owners of websites tailor their data collection to meet unique tracking requirements and gain deeper insights into what users do.
