How to Configure Your Facebook Page for Maximum Exposure
Allow Facebook users to post photos and videos to your page.
Doing so increases your page’s exposure to those users’ friends.
For example, the friends of the Facebook users who've posted these photos of rabbits will see a story in their News Feed, exposing them to the National Wildlife Federation. Also, when people tag any photo posted by NWF or by Facebook users, the person being tagged receives a notification, exposing them to the National Wildlife Federation.
