You have three clickable areas or actions. (When on the notifications update page, you can only perform actions #1 and #2)
1. Log into your account and click the name of the person the notification is from to view their profile
2. You can click the words 'post', or the group name of where the post was made, to be taken to the exact place where the update occurred
3. Click anywhere else in the notification to go to the page to be taken to the exact place where the update occurred
