Introduction to Google Tag Manager

Google Tag Manager (GTM) is a user-friendly tag management system (TMS) designed to streamline the process of integrating and managing measurement codes, collectively known as tags, on your website or mobile app.

• It enables swift and secure analytics and measurement tag configurations from a web-based user interface.
• It offers valuable insights on user behaviour, ensuring an effective digital marketing strategy.
• It allows for seamless collaboration and versioning capabilities.

How Does Google Tag Manager Work?

Once a small segment of the GTM code is embedded into your website or mobile app, your platform can communicate with GTM servers. This interaction facilitates the configuration of tags, the establishment of triggers that fire tags during specific events, and the creation of variables for easier tag configurations.

A collection of tags, triggers, and variables installed on a website or app is referred to as a container. A GTM container can replace all other manually-coded tags on a site, including tags from Google Ads, Google Analytics, Floodlight, and third-party tags.

Google Tag Manager versus Google tag (gtag.js)

Both GTM and gtag.js, a JavaScript framework used to add Google tags to web pages, provide reliable methods for deploying tags for Google products. While the two offer similar functions, there are distinct reasons to consider one over the other:

• Consider GTM if you require the ability to deploy and modify Google and third-party tags, to manage tags for web and mobile apps on-the-go, and for collaboration and versioning capabilities.
• Consider gtag.js if you want to install tags directly onto your web page, or if working with tags in JavaScript without a separate interface is essential for you.

Note that GTM does not fully support all Google tag functionalities associated with Google Ads. If you’re currently using GTM, continue doing so. You can always upgrade to GTM from gtag.js later if needed.

Google Tag Manager Configurations

GTM supports two primary configurations: client-side tagging and server-side tagging.

• Client-side tagging: A single container resides on your website or app, holding all the necessary components to measure user interactions. The event data is dispatched into HTTP requests to your Google products or advertising partners when the user triggers a tag.
• Server-side tagging: This involves two containers, a web container on the website or app, and a server container in a cloud environment. The server container processes rules before sending data to Google products or third-party endpoints.

Components of Google Tag Manager

GTM utilizes four core concepts: tags, triggers, variables, and the data layer.

• Tag: Code that sends data to systems like Google Analytics.
• Trigger: Listens for certain events, such as clicks or page loads, firing tags when a match is found.
• Variable: A named placeholder for a value that can change.
• Data Layer: A temporary holder for values used by tags, triggers, and variables.

GTM provides built-in variables and the ability to configure custom variables. The data layer holds information temporarily, allowing variables to retrieve data either directly or from a well-organized data layer object.
