Google Tag Manager

Google Tag Manager is a free tag-management system that lets marketers and developers deploy and update tracking scripts without direct code releases.

What is Google Tag Manager?

Google Tag Manager separates marketing-tag deployment from engineering release cycles by offering a browser-based container that loads tags, triggers, and variables. It supports analytics, advertising, conversion tracking, and custom data layers. That makes it attractive for marketers who need speed and for developers who want fewer site-code edits. The risk is implementation sprawl; GTM still benefits from a clean data layer, naming standards, and change-management controls.
