Shared Google Drive phishing email

On Friday night we started receiving phishing emails asking a user to read a private message.  Following the link would take you to a fake Google login screen.  If you did try to log in to that page you will need to change your password right away.

What are the obvious ways I could tell this was not legitimate? The simplest is that if you did follow the link you would be at a fake address: http://bandmansion.com/something.
