What is Google Tag Manager (GTM)?

Google Tag Manager (GTM) is a tag management system (TMS) that allows you to quickly and easily update measurement codes and related code fragments collectively known as tags on your website or mobile app. Once the small GTM container code has been added to your project, you can safely and easily deploy analytics and measurement tags from a web-based user interface. GTM is commonly used to manage and deploy marketing and analytics tags (like Google Analytics, Google Ads conversion tracking, Facebook Pixel, etc.) without modifying the website's code directly. It simplifies the process of adding and managing these tags, making it easier for marketers and analysts to track website activity and campaign performance.
