Have you just posted a new status update on your Facebook business page, and now you want to share it on your personal timeline so the business contacts you have added as friends can see it too?
(E.g. inviting people to book a free consultation with you)
Perhaps you’ve been asked to (or want to) share the post in a Facebook group you’re a member of?
(E.g. because it’s the one day of the week you’re allowed to promote your business in the group, and you know your ideal clients are also members of the group.)
