What is GTM (Google Tag Manager)?
Google Tag Manager is a tag management system that allows you to quickly and easily update tags and code snippets on your website or mobile app such as those intended for traffic analysis and marketing optimization.
Using the tag manager you can also fire your specific tag according to trigger on your website.
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.
We can create custom triggers based on different event like DOM Ready, Page View, Window loaded etc.
