I think the graphic is quite self-explanatory, but here is the list:
- SALE – you can't offer information on discounts and prices
- LIKE – you can't use like or share visuals, neither arrows pointing to those elements in FB'S UI
- CONTACT – no contact information allowed (web, email, phone number)
- SHARING – prohibited to encourage content sharing “Share now”, “tell your friends”
Make sure you share this valuable information!
