Hi Siamee99 and welcome to the forum!
You're right...currently there is no way to track statistics on a group page (same as with the actual profile page). However, if you create an actual application for your purpose then you should be able to track views (even so, one must first agree to allow their activity on that application to be tracked). Of course, creating a application instead of a group will require a lot more time and skill to set up.
