What is Google Tag Manager?

Google Tag Manager is a Tag Management System (TMS) introduced by Google which allows you to control different tracking codes, including marketing tags, analytics tags, and other code snippets on your web or mobile applications.

Tags fire in response to events. In Google Tag Manager, a trigger listens to your web page or mobile app for certain types of events like form submissions, button clicks, or page views. The trigger tells the tag to fire when the specified event is detected.

Tag: A tag is code that send data to a system such as Google Analytics.

What is data layers in Google Tag Manager?

A data layer is  used to describe information that isn’t available as part of DOM (Document Object Model) or any other JavaScript variables. When you set up your website or mobile app to work with Tag Manager and a data layer, think about what categories of information the data layer should handle, such as:

Product data: Product name, price, category
Marketing campaign information: Traffic source, medium
Transaction data: Cart value, checkout date
Customer information: New or returning customer

Data layer variables enable Tag Manager to read values from your data layer implementation and pass those values to tags, triggers, and other variables. A data layer object is made up of a list of key/value pairs. A key is a category of things – a book's category, title, or author. Each key could have different values. A book's title key could have a value of 'Ulysses', 'War and Peace', 'A Brief History of Time', etc.
