Brief overview of Google Tag Manager (GTM)

Google Tag Manager (GTM) is a powerful and user-friendly tool developed by Google that allows marketers, analysts, and developers to manage and deploy marketing tags (snippets of code) on their website or mobile app without having to modify and edit the source code directly. GTM simplifies the process of adding, editing, and managing various types of tags, such as those used for web analytics, marketing optimization, and tracking user behavior.

Importance of using variables in Google Tag Manager

Google Tag Manager - Built In Variables

Variables in Google Tag Manager are essential components that significantly enhance the flexibility, efficiency, and precision of tag management. They serve as placeholders for values that can change, such as tracking IDs, user inputs, or dynamic data from the website. By using variables, you can dynamically insert these values into tags, triggers, and other variables, making your GTM implementation more dynamic and scalable. For instance, variables can capture information such as page URLs, click elements, and form submissions, enabling more tailored and effective tracking.

Here’s why variables are important:

  1. Dynamic Data Handling: Variables allow GTM to dynamically capture and use data from your website or app. This enables more accurate and context-specific tag firing, ensuring that tags are triggered only when specific conditions are met.
  2. Simplification and Reusability: By defining variables, you can reuse them across multiple tags, triggers, and other variables. This reduces redundancy and simplifies the management of tags, making the setup cleaner and easier to maintain.
  3. Improved Accuracy: Using variables ensures that the correct data is passed to your tags consistently. This improves the accuracy of your data collection, which is critical for making informed business decisions based on reliable analytics.
  4. Better Performance: By using variables to manage tag firing conditions, you can minimize unnecessary tag executions. This can lead to improved website performance, as fewer tags are loaded unnecessarily, reducing load times and improving the user experience.
  5. Simplified Debugging and Testing: Variables make it easier to test and debug your GTM setup. By isolating and inspecting variable values, you can identify and resolve issues more efficiently, ensuring your tags are working as intended.

Introduction to Google Tag Manager Built-in Variables: Page URL, Page Hostname, Page Path, and Referrer

Understanding and utilizing specific variables in Google Tag Manager can greatly enhance your ability to track and analyze user behavior on your website. Built-in variables (for example, Page URL, Click Text) and user-defined variables (for example, JavaScript variables, Data Layer variables) allow you to capture detailed information about user interactions. By leveraging these variables, you can create more precise and meaningful tags and triggers, leading to richer data insights and more effective optimization of your digital marketing strategies.

Upcoming changes to Google Analytics: Conversions to Key Events

Here, we will introduce four essential built-in variables for tracking page-level activity: Page URL, Page Hostname, Page Path, and Referrer.

Page URL Variable

The Page URL captures the full URL of the current page, including the protocol (http/https), hostname, path, and query parameters. This variable is crucial for tracking and segmenting user interactions based on the complete web address.

The example below shows how complete URLs are broken down into segments.

For the complete URL, https://cats.example.org.au:1234/stripes/fur.html?pattern=tabby#claws, the breakdown is as follows:

  • Site: https://cats.example.org.au
  • Origin: https://cats.example.org.au:1234
  • Hostname: cats.example.org.au 
  • Scheme / protocol: https and https://
  • Registrable domain / eTLD+1: example.org.au 
  • eTLD: org.au
  • TLD: au
  • Port: 1234
  • Pathname: /stripes/fur.html
  • Filename: fur.html
  • Search: ?pattern=tabby
  • Query: pattern=tabby
  • Hash: #claws
  • Fragment: claws

Understanding how a URL breaks down is important for variable tracking. In GTM, each segment of the URL can be captured as a separate variable, enabling more granular and precise tracking. This detailed tracking allows you to analyze specific components of user interactions, such as identifying the exact path users take, filtering by query parameters for custom reporting, and monitoring specific elements like fragments and ports to optimize website performance and user experience.
