Facebook have introduced some new strict rules about competitions on your Salon’s facebook page.
In essence -
Anytime you run a campaign on Facebook where you wish to select a winner, that is a Promotion and falls under their new guidelines.
And the guidelines say -
You will not administer a promotion through Facebook, except through an application on the Facebook Platform. Administration includes operation of any element of the promotion, such as collecting entries, conducting a drawing, judging entries, or notifying winners.
Which means -
You can’t use Facebook’s features for your promotions!
Unless – you use a 3rd party application on a Tab.
How to use a 3rd party application is covered in this post Tabs for Salon Facebook Pages
