Ever published a fantastic piece of content on Facebook, only to have a friend tell you they couldn't share it with their network? That little setting is the culprit, and it's holding back your content's reach from the wider audience you want to connect with. This guide breaks down exactly how to make your Facebook post public, whether you're about to post, need to change an old one, or just want to set Public as your default so you never have to think about it again.
Before getting into the step-by-step, it's worth understanding the choices you have and why "Public" is so powerful. Facebook is all about letting you control who sees your stuff, and it gives you a few primary options for your posts:
For brands, creators, marketers, or anyone trying to build a presence, the Public setting is essential. Think of it as opening the doors to your shop. When a post is public, it can be shared by anyone, appear in search results both on and off Facebook, and has the potential to travel far beyond your immediate list of friends. It's the only way to tap into the network effect that makes social media such a transformative tool for growth.
Getting it right from the start is the easiest way to manage your audience settings. Here's how to set a new post to Public before you hit that publish button, whether you're on a computer or your phone.
When you're working from your laptop or desktop, the audience selector is easily visible right inside the post creation window.
The process on the Facebook mobile app is just as simple. The audience selector is in a similar location and is easy to change before you publish.
Don't worry if you've already shared something with a limited audience. Facebook makes it incredibly easy to go back and edit the visibility of any post you've made. This is useful for when an older post suddenly becomes relevant again and you want more people to see and share it.
Finding the setting on an existing post takes just a couple of clicks.
And that's it! The privacy setting for that specific post is instantly updated, and the icon next to the timestamp will change from the friends icon to the public globe icon.
The steps on your phone are almost identical and just as quick.
The change is saved automatically, and the post is immediately accessible to a public audience.
If you're a business owner, a public figure, or a content creator who always intends for their posts to be public, changing your default setting can save you time and prevent accidentally posting privately. Facebook's system typically remembers your last used audience setting and applies it to your next post, but you can check and set your global default to be sure.
Here's how to review and potentially change your default audience settings for future posts:
After you set this, Facebook will default to "Public" anytime you create a new post, though you can still change the audience for any individual post before you publish it. It offers peace of mind that your content is going out with the broadest possible reach unless you decide otherwise.
Sometimes you might run into a situation where the "Public" option is grayed out or simply not available. This almost always comes down to where you are posting, not a problem with your account.
This is the most common reason. If you're posting inside a Facebook Group that is set to "Private" or "Closed," the group's privacy settings override your personal settings. All content shared inside a private group is visible only to other members of that group. There is no way to make a post within a private group public. You would have to share the content on your own timeline or a Public Page instead.
Within Facebook's Privacy Settings, there's a tool called "Limit Past Posts." If you have ever used this feature, it automatically changed the audience of all your past public posts to "Friends" in one action. This tool is a one-way street, to make those posts public again, you must go back and change the audience for each one manually.
This is less of a problem and more of a clarification. Posts made from a Facebook Business Page are public by default. Pages are designed for public figures, businesses, and organizations, so content is meant for broad distribution. If you're managing a Page and your content isn't visible, check that the entire page is published and visible. This setting can be found in your Page Settings.
Flipping the switch to "Public" is more than a technical setting, it's a strategic decision. By making your content public, you unlock doors for growth that are simply not available otherwise.
Deciding when to use "Friends" or a custom list is just as important. Save those settings for personal life updates, family photos, or discussions where you're seeking input from a trusted circle. For anything related to your business, brand, or personal creative work, think "Public" first.
Making a Facebook post public is a simple action, but it's central to using the platform for growth. By understanding how to check the settings for new posts, edit old ones, and set your default for the future, you gain full control over who sees your content and how far it can travel.
