When creating your website your Account Manager will set up your website with Google Analytics which can give you all sorts of statistics such as your total views, the amount of time people stay on your website, and even how they found your website in the first place.
You can talk to your account manager about the kind of statistics you would like to see on your site, and they will set up a recurring report for you. The report will be delivered to your email on a regular basis, allowing you to keep tabs on your site performance.
If at any point you are unsure of what the data is showing you, you can contact your Account Manager who will be able to talk you through the results.
