Is there a way to share a post to all your friends at once without having to pick them individually?
What you want is simply not allowed in fb...
Sharing on a friend's wall will make it visible to any of their Friends. Facebook will not allow you to share something on all of your Friends' walls in a single click.
The least labor intensive way of accomplishing this task is to share the post on a friend's wall and tag up to 10 people on the message of the post and up to 50 people on a photo. Then just re-share the post multiple times, tagging 10 people at a time.
So, if you are trying to market something so that the largest group of possible people 2 degrees from you (Friends and Friends of Friends) so that they see your post in their News Feeds, buy Marketing dollars and target your audience.
Basically, you have to pay for that level of visibility and ease.
Under Privacy Settings, you can choose how you want share your posts. You have three choices: 'Public', 'Friends', and 'Custom'. You just need to choose 'Friends'.
I don't think FB allow this.
share a post to all your friends at once without having to pick them individually
There's no way to ensure everyone sees a particular message on Facebook without tagging them. There are simple too many people on the platform for that to work. Contact people directly if you need to, I guess.
If you click the share button and in the right corner you select Friends of Friends (or just Friends) then that share can be seen by everybody that is looking on your account or you are in their news feed.
The easiest way , I believe, is to create a group with the persons you want to share (maybe many times from now) and the next time you select share, you can select that group from the list.
If you want to share your post to your 'friends only' then follow the instructions in the link below as it'll guide you -
I assume you would have to change your facebook security settings so that all friends can see what you post and share.
Im sorry Privacy settings not security settings.
