Google Tag Manager (GTM) is a free tool by Google that allows website owners to manage and deploy various tracking codes, scripts, and tags on their websites without the need for manual code implementation.
GTM simplifies the process of adding and updating tags, such as those used for analytics, conversion tracking, or remarketing, by providing a user-friendly interface.
A marketing team can use GTM to deploy tracking codes for Google Analytics, Facebook Pixel, and other marketing tools without directly modifying the website's code.
