Whenever someone shares a link on Facebook, they normally see a picture, a title, and a description of the link.
How does Facebook get this information?
Well, if you don't use the Open Graph Protocol, then it guesses. It takes a look at your site and tries to get a picture. It also may look at the meta description tag, I'm not sure.
But if you use the Open Graph Protocol on your webpage, then you can control what is displayed when someone shares your link! All you need to do is put some new meta tags in the <head> section of your webpage.
Here is an example of how to put this on your site:
You can also specify a GPS location, other location information, an audio file, a video file, contact information, and a type. To use those other tags, visit the Open Graph Protocol Website for more information.
EDIT:
Facebook has one more field you can add that isn't specified in the Open Graph Protocol Website
This field will show who is the administrator of the page! You can put your Facebook User ID here.
