Multiple 3rd party tags will be placed in a google tag manager that helps to reduce the page load with just 1 javascript code.

In a simple way each 3rd party tracking codes into the tag within the container in a single javascript code.

What is a container, and It’s ID in GTM: 

Container:

Preview Mode:

preview mode is helpful to see how your tag behaves on a real page and can be useful when you are testing different creatives, or if you want to check how your website will behave after adding new tags. 

When the Preview Mode option is enabled and a tag is added, Tag Manager automatically adds a snippet of code to the page header to enable preview mode for that tag. 

When preview mode is turned off via the GTM settings page, the code snippet is removed from the header and loading that tag will no longer reload the page.

Debug mode is an important tool when working with Google Tag Manager. You might have many tags on your page. So, it is useful for troubleshooting errors in your Google Analytics implementation. It allows you to easily test your tags, triggers, and rules.
