What happens when someone likes your facebook band page?

[Matt]

Can they see who "liked" it? What if you liked it by mistake and immediately "unliked" it through the facebook settings? Will the admin of the band page still be able to see if you liked it or not?

"Like" is a way to give positive feedback or to connect with things you care about on Facebook. You can like content that your friends post to give them feedback or like a Page that you want to connect with on Facebook. You can also connect to content and Pages through social plugins or advertisements on and off Facebook.

The visibility of posts you make on your own Wall (timeline) depends on the audience you choose for each post using the audience selector. For example, a friend will see posts you've set to Friends and Public, while a non-friend will only see posts you've set to Public. If you do not have any public posts, then a non-friend will see a blank Wall tab.

The visibility of posts others make on your Wall (timeline) depends on the setting you've chosen for who can see posts by others.

You can remove an individual post whenever you want.

To control who sees stories that games and apps you use publish to your Wall (timeline), change your app privacy setting.
