Firstly you will need to go to Google and get an analytics account set up.
(follow this link) http://www.google.com/analytics/
Sign up for this service (free)
Once you have signed up, Create/Add a new account > Name the account > Website Name > Website URL > Industry > Time Zone > Share > click GET TRACKING ID > Google will provide you with a code. COPY THIS CODE (to paste later)
Go into the RSP Control Center > Site Manager > GOLIVE/IDX > Google Analytics code. Paste in (Enter) the code, submit, and then Google is attached to your site. It starts generating data immediately, so get a log in immediately after its set up, then check to make sure it's linked up. If you get stumped, feel free to open a support ticket and have us set it up for you.
