Here comes Google Tag Manager!Posted by on October 9, 2012 06:44 AM
Google Tag Manager allows you to enter all your tags in one location. You define on which page or pages a particular tag should appear and the magic of Google does the rest. This is particularly useful if you manage more than one site that each uses multiple tags.
You need to create a new Tag Manager account to use it. Despite needing a new account, you still will need all your other Google accounts like Analytics, AdWords, and the like.
