From your business page, click your profile icon under your profile and banner image. Select your personal page. Scroll down to find the post you want to share, and click Share.
Tap the three dots to open the page’s menu, where you can then draft a post. Choose to share on your timeline or to another location with the option at the top of the screen.
Make sure the first pull-down menu says Share On A Page You Manage. If it doesn’t, click on the arrow and select this option. Next, make sure the second pull-down menu directly below displays your Page (especially if you manage more than one). If it doesn’t, click the pull- down arrow and select the correct page.
How do I put someone else’s post on my timeline?
Use the drop-down box in the “Share This Status” dialog box to choose who you want to share the post with. You can repost to your own timeline, a friend’s timeline, to a group, on a page you own or as a private message to another user.
Your friend may have added you to one of her custom friend lists. This may be the case if other members are able to post on her timeline but you are not. She may have put you on an “Acquaintance” list and then adjusted her privacy settings such that people on that list cannot post on her timeline.
Officially you can’t. Facebook treats it like a comment of sorts, so it’s just like you can’t officially share comments.
To try out the Share button, go to m.facebook.com and scroll through the feed until you see a story about a link, photo, video, or public status update posted by one of your friends or Pages you Like. The Share button is in the bottom right next to the Like and Comment buttons.
If you want to make a previous post shareable, after locating the post, select the ellipsis icon (•••) on the right side of the post and choose “Edit Post.” Select the first drop-down menu below your name (labeled “Friends”) and choose “Public” on the new page.
