In 2012, Google introduced and released a new product of Google Analytics (GA), known as Tag Manager, Google Tag Manager or GTM. Google Tag Manager is a free tag management tool also called as a tag management system provided by Google. By this free online tool, you can install or use and run several marketing and analytics tags on a mobile app and website.

A lot of confusion is there about what Google Tag Manager is, what it does exactly, and how it is different from GA (Google Analytics). A popular confusion is that Google Tag Manager is the advanced version of GA and it has similar things as Google Analytics. Actuality, GTM is a totally different tool.

Google Tag Manager is a user-friendly tool that simplifies the procedure of adding JavaScript snippets to a site. Instead of inserting code on a site, you can choose the interface to determine what should be fire, what action and on what page. Google Tag Manager then adds the suitable tracking to your website to ensure it all works.
 

There are three main elements in Google Tag Manager:

  1. Tag: A JavaScript snippets (JavaScript code) added to a webpage.
  2. Triggers: It determines where and when tags will be executed.
  3. Variables: It used to get and save information to be utilized by triggers and tags.
