Here are just some notes I am making as I try to work out how to use this.

• https://analytics.google.com - to sign up

It seems that you sign up to google analytics with your google account.

Then you can add websites to be analysed.

You add analytics account - you can have more than one. Eg we have New Zealand Digital Library account.
