Whether your Facebook profile is completely locked or not, other users can easily find and view your Facebook page. This situation even includes people who are not on your friends list. Depending on your account visibility, they will see different amounts of information about you.
But can you see who viewed your Facebook page? Or better yet, can you see who viewed it the most?
The sad answer is no. You cannot officially see who has visited your Facebook page/profile. Facebook claims there is no way to see the name of visitors to your profile, and they have no plans to make this possible in the future. They also state that no third party has access to this information and to report it if you find one that claims such a statement. Anyway, Facebook's decision on this is mostly due to privacy concerns and policies.
If you have doubts about what you have already seen on the Internet, read this article and find out the truth!
Claimed Methods to See Who Viewed Your Facebook Profile
Sure, there are some websites that explain how to source your Facebook profile page, but the two different processes scattered all over the internet are not correct. Others have claimed that the iPhone has an option in 'Privacy Settings' that says 'See who's viewed you', which will also be explained. Finally, many third-party extensions or apps claim to reveal who viewed your Facebook profile, but that's not true either. Here are the essential details of all these scenarios.
See who viewed your Facebook profile using View Page Source
When you search the internet, you can find two different ways to show you who visited your Facebook profile by using the "View Page Source" option. 
One method is to search for “Initialchatfriendslist”.
Technically speaking, the initial list of chat friends is the order of the friends list displayed in your chat bar on the right side of your Facebook page. Many factors determine the order, but this is officially an ordered list of users Facebook thinks you're most likely to chat with based on many algorithms. This feature is already available on your profile, so there is no need to hide it, even in the page source.
The second method is to search “BUDDY_ID” to find stalkers and friends who have recently viewed your Facebook profile.
First, you won't see anyone on the list who is NOT your friend. Second, the Friends list are simply people with whom you have communicated recently in some way.
See Who Viewed Your Facebook Profile Using iPhone
Another solution on the web to see who is viewing your Facebook profile says you can use your iPhone to view these profile viewers. You go to the "Security and privacy" menu on Facebook and click on "Who viewed my profile?" » connect. 
First of all, this scenario is against Facebook policies, even if someone states that Facebook has made a deal with Apple.
Second, this option would have been available in April 2022, but there were never more words. Some reports say it was available on April 1, 2022. Maybe that was a temporary glitch or opportunity? Maybe it was an April Fool's Day joke? We'll never really know, and no, this scenario wasn't a test and won't be rolling out to Android.
View Your Facebook Profile Users Using Third-Party Apps
You may find browser extensions or even apps that claim to be able to show you who has viewed your Facebook profile.
For starters, Facebook states that there is no way to see who has viewed your profile as it would be a breach of privacy. As mentioned earlier, Facebook says to report to them any third party that makes such claims.
All apps that claim to show you your profile users give false results because they don't have access to Facebook's profile usage data.
Moreover, most third-party Facebook profile viewer apps are designed to steal your personal information and credentials, or they infect your devices with malware. Finding FB profile viewers is a hot topic so it becomes a target for hackers and thieves.
Secure your Facebook profile
The best way to protect your Facebook profile is to limit the amount of information "strangers" can see when they come across your profile. By "strangers", we mean people who are not your Facebook friends and whom you do not know in person.
Information that you should hide from others if you want to be as secure as possible includes the following:
a) email address
b) date of birth
c) telephone number
d) relationship status
To do this, log into your Facebook account and follow the steps below. This tutorial covers the Desktop version of Facebook, but you can also follow it on your smartphone as the options are the same.
- Go to your account settings.
- Click on the Privacy option. This will take you to a page where you can adjust your profile privacy settings.
- Click Who can search for you using the email address you provided and set it to Me only.
- Next, select Who can search for you using the phone number you provided and also set it to Me only.
- Return to your Facebook profile page.
- Click Edit Profile.
- Find the information you entered (date of birth, relationship status, etc.) and delete it.
