You can plug in your Google Analytics number into Site Settings to enable your site to track visits and other metrics. 

If you don't already have an Analytics account, you can create one here:  Once you sign up, the account number should be pretty obvious - you're looking for something like UA-12345678-1 - that's the number you'll plug in to Site Settings on your Streamline site:

Once you have the number plugged in, you'll be able to go to and sign in to view all kinds of reports on site traffic.
