Google Tag Manager keeps track of a set of tags and tag-firing triggers that define when those tags should be made available on your site. When a user visits the site, the most up-to-date tag configuration is sent over to the end-user’s browser with instructions for which tags should fire.
“With Google Tag Manager, it’s a matter of an hour or so from receiving a tag to testing to QA to deployment. It’s exponentially better.”
