Google Tag Manager is a free tool provided by Google that simplifies the process of managing and deploying marketing tags (snippets of code or tracking pixels) on a website or mobile app without needing to alter the code directly. It allows users to add and update tags for various tracking and marketing services, such as Google Analytics, AdWords, and other third-party tools, through a user-friendly interface. By using Google Tag Manager, businesses can streamline their tag management process, reduce reliance on developers for tag updates, and implement tracking changes more efficiently.
