From the Website Editor Control Panel, click on Site Statistics.
The stats area provides figures relating to the traffic to your website over the past 13 months. This is measured in terms of page requests, which is basically the number of times a user clicks on a link on your website.
The Site Statistics area gives you breakdown of page requests per month over the past 13 months (as well as MB of data downloaded/ viewed), and per day over the past week.
At the bottom of the Site Statistics page is the number of members who have signed up for email reminders and upload notifications (members can do this through Passport).
