Facebook does not show you a list of who shared your post
When someone shares your post on Facebook, you cannot pull up a complete list of their names the way you can see who liked or commented. Facebook removed this visibility years ago, and it has not returned. You will see a share count on your post — a number telling you how many times it was shared — but not the identities of those people.
What you can do instead is search for your post in the feeds of people you suspect shared it, or check your notifications if someone shared it to their timeline in a way that tagged you or your page. You can also look at your page insights if you run a Facebook Page (not a personal profile), which shows aggregate sharing data without naming individuals.
This limitation exists by design. Facebook prioritizes user privacy in shares, treating them differently from public comments or reactions. A share is often more private than a like — someone might share your post to a closed group or with a specific audience, and Facebook does not expose that activity to you.
Key Takeaways
- Facebook shows you the total number of shares on a post but does not reveal who shared it, even if you are the post's author.
- If someone shared your post and tagged you or your page in the share, you will receive a notification with their name.
- You can manually search for your post in someone's timeline or feed if you think they shared it, but this is slow and unreliable.
- Facebook Page owners can see sharing data in their page insights, including which posts were shared most, but not who shared them.
- Third-party tools and browser extensions that claim to show you who shared a post are not reliable and may violate Facebook's terms.
When you will get a notification about a share
Facebook sends you a notification in two specific cases. First, if someone shares your post and you are tagged in the share itself — meaning your name appears in the share caption or the post mentions you — you will see a notification. Second, if someone shares your post to their timeline and their privacy settings allow you to see it, and Facebook's algorithm decides it is worth notifying you about, you may receive a notification.
These notifications appear in your notification center (the bell icon at the top of Facebook). They will say something like "John shared your post" or "Sarah shared your post with her friends." Clicking the notification takes you to the share, where you can see the context in which it was shared.
However, if someone shares your post to a private message, a closed group, or with a custom audience that does not include you, you will not be notified and will never know they shared it. This is the majority of shares — most people do not share publicly.
Checking your page insights for sharing data
If you manage a Facebook Page (a business page, creator page, or community page — not a personal profile), you have access to page insights, which include sharing information. Open your page, click the "Insights" tab at the top, then look for the "Posts" section. This shows you which of your posts were shared the most, ranked by share count.
Page insights tell you that a post was shared 47 times, for example, but they do not tell you who did the sharing. The data is aggregate only. You can see trends — which types of posts get shared more, when shares happen, and how shares compare to likes and comments — but you cannot drill down to individual names.
This data is useful if you are a creator trying to understand what content resonates with your audience. Posts that get shared more often reach further and tend to generate more engagement overall. But if your goal is to contact the people who shared your post, page insights will not help you do that.
Manually searching for your post in someone's timeline
If you suspect a specific person shared your post, you can visit their timeline and search for it. Go to their profile, scroll through their posts, or use the search function within their timeline to look for your post. If they shared it publicly or with an audience that includes you, you will see it there with their name attached as the person who shared it.
This method works only if the share is visible to you — meaning the person who shared it set their privacy settings to allow you to see it. If they shared it to a closed group or a custom audience that excludes you, you will not find it on their timeline even if they did share it.
This approach is impractical if you are trying to find multiple people who shared your post. You would have to check dozens or hundreds of timelines manually. It is useful only when you have a specific person in mind and want to confirm whether they shared something.
Why Facebook does not show share attribution
Facebook treats shares as a semi-private action. When you like a post, that action is usually public and visible to others. When you comment, your words are public. But when you share, you are often sending something to a specific audience — a closed group, a subset of your friends, or people in a particular location. Showing the post author who shared it would expose the sharer's audience and sharing habits, which Facebook considers private information.
This design choice also protects creators from harassment. If every share were attributed and visible, creators could potentially contact or confront people who shared their content in ways they did not like. By keeping shares semi-anonymous, Facebook reduces that friction.
For creators trying to understand their reach, this is frustrating. But for users sharing content, it provides a layer of privacy that many people value, even if they do not think about it consciously.
What third-party tools claim to do
Various browser extensions and websites claim they can show you who shared your Facebook post. These tools are not reliable, and many violate Facebook's terms of service. Facebook actively blocks access to this data, so any tool that claims to retrieve it is either not actually retrieving it, is retrieving outdated or inaccurate data, or is accessing your account in ways Facebook prohibits.
Some of these tools ask for permission to access your Facebook account. Granting that permission puts your account at risk — you are giving a third party the ability to log in as you and take actions on your behalf. Even if the tool's creator has good intentions, their servers could be hacked, or the tool could be sold to someone with bad intentions.
The safest approach is to rely only on Facebook's built-in features: notifications, page insights, and manual timeline searches. These are slow and limited, but they are find and actually work.
Frequently Asked Questions
Can I see who shared my post if I shared it to my own timeline?
No. Even if you shared your own post, Facebook does not show you who reshared it. The share count is visible, but the names are not. You will only know if someone shares it and tags you in the share, which triggers a notification.
Does Facebook notify me every time someone shares my post?
No. Facebook notifies you only if the share is tagged with your name or if the sharer's privacy settings make the share visible to you and Facebook's algorithm decides to send you a notification. Most shares happen silently, and you will never be told about them.
If I run a Facebook Page, can I see who shared my posts?
Page insights show you how many times each post was shared, but not who shared it. You can see which posts performed best in terms of shares, but you cannot identify individual people who shared them.
What happens if I use a browser extension to check who shared my post?
Most extensions that claim to show share data do not actually work, or they work by accessing your account in ways that violate Facebook's rules. Using them risks your account security. Facebook actively blocks this type of access, so any tool that claims success is either fake or dangerous.
Can I message someone to ask if they shared my post?
Yes, if you suspect a specific person shared your post, you can ask them directly. But there is no way to generate a list of people to ask — you would have to contact people one by one based on a hunch.
