Google Tag Manager

I am taking an ALA class on Customizing Google Analytics and Google Tag Manager.  This is my 2nd week and I have learned a lot.  This weeks lesson is on enhancing Google Analytics data.  I look forward to posting about my class progress and share my library experiences.  This weeks reading "Using Google Tag Manager in Your Library".  Google Tag Manager (GTM) article notes:

• GTM- what data gets tracked and how
• Event tracking- An event is a user action that can not be automatically tracked in Google Analytics
• What you want to track and when you want to track it
• 1st tag you should create is a Google Analytics tag
• Triggers- tell the GTM tag when to fire and collect the data

I had trouble with adding the tag manager script to the blog.  The post response on this site worked.
