Google Tag Manager

Google Tag Manager is a tag management system that allows you to update tracking codes and related code fragments (known as "tags") on your website or mobile app. It simplifies the process of managing various marketing and analytics tags from Google and third-party vendors. With Google Tag Manager, you can add and update tags yourself without needing to edit your website`s code directly. This enables you to implement tracking, analyze user behavior, and optimize your advertising campaigns more efficiently.
