Google Tag Manager is a free tool that makes it easy for marketers to add and update website tags -- including conversion tracking, site analytics, remarketing, mobile number tracker with name and more—with just a few clicks, and without needing to edit your website code. Take a quick look at how easy it is to set up an account and manage your tags.
A container in Google Tag Manager holds the variables and triggers (formerly known as rules and macros) which govern how the configuration and flag values in your app are set. You manage the container – editing its variables and triggers, previewing, testing, and publishing new versions of the container – from your Google Tag Manager account. During app development, you use the Google Tag Manager SDK to associate a container with the app.
