If you are having such a high list of close friends as well as signed up with some multitude of teams than you may have some difficulty with the alerts. I know this due to the fact that a lot of my friends are addicted to playing those Facebook games as well as I got many alerts of invitations and demands.
Not taking way too much time with my very own issue I wish to share what I am doing to stop those notifications.
How To Stop Facebook Notifications
ACTIONS
1. Go to your Facebook profile.
2. Click on the "Alert". Where you obtain all your alerts.
3. You can see establishing alternative there. Select it.
4. Now choose when you want notification.
5. Select your Alternative as well as minimize your checklist of alerts.
Those are the actions that you have to do. Well with this method you can not stop all alert but it will surely minimize the number of the notifications. In my case it minimized to the 40-50%. So it is worth to try to quit to some worthless applications and game alerts.
