What is Google Tag manager?

Google Tag Manager is platform neutral and handles 3rd party tags with ease.

Google Tag Manager is a tag management system created by Google to manage JavaScript and HTML tags used for tracking and analytics on websites (variants of e-marketing tags, sometimes referred to as tracking pixels or web beacons). You can add and update AdWords, Google Analytics, Firebase Analytics, Floodlight, and 3rd party or custom tags from the Tag Manager user interface instead of editing site code. This reduces errors and frees you from having to involve a developer when configuring tags.

Google Tag Manager helps make tag management simple, easy and reliable by allowing marketers and webmasters to deploy website tags all in one place.
