voucher if you click "like"-button

[cangoou]

Hello! I see some shops offer a voucher if you "like" them on facebook (like: [facebook.com...]

How is it done if I want to offer that for my shop? Couldn't find anything in the facebook-help.

You can use "fb:visible-to-connection" to show content only to fans.

One thing to be aware of with visible-to-connection is that even users who haven't liked your page can still view the content by looking at the source. They use css of visibilty:hidden as opposed to display:none

I signed up for one of these and I received an email with a $5 gift certificate. I too would like to know how this is done.

The best way to do this now is to use an iFrame app. You can then more easily see if someone is or isn't a fan of your page
