Click on your Profile name at the top which is in between "Search Box" and "Home."
Under "Intro" section (which you can see at the left side of the screen), you can see "Followed by X people." X is the number of your followers.
Click on it, and you can see your Followers list.
Besides "Followers," you can see "Following" which you can click to look at whom you are following.
Go to Facebook. Sign into your account.
Click on your profile name at the top which is in between "Search Box" and "Home."
You can see "Friends" under your "Cover Photo." Click on it, and you can see your Facebook friends now.
Hit on "Followers" tab to see your followers.
Click on "Following" tab to see all whom you are following.
Note: Keep in mind that after you click "Friends," look for "More" option if you did not find "Followers" or "Following."
If you find "More," hover the mouse over it, and you may see "Followers" and "Following."
For Seeing Followers
Open Facebook app.
Tap "Hamburger" icon (three vertical lines) and then tap your profile name.
Now, under your profile name, you can see your "Intro." Within that, you can see "Followed by X people." X is the number of your followers.
Tap on it to see your followers list.
For Seeing Whom You are Following
Open Facebook app.
Tap on "Hamburger" icon (three vertical lines) and then click on your profile name.
Hit "Activity log."
Tap "Category" drop-down list and then choose "Following."
Now, you can see the people and pages you are following.
If you do not see followers using above methods, then it means that you do not have any followers.
You may not see all followers of your Facebook account and it may because of followers account settings.
If you do not see "Following" tab, then it means that you are not following anyone or any page.
Here is the last important thing to note: Let's say that you are following a page and not a single person, then you cannot see the count on the top of "Following" tab (above screenshot on the second method on "PC" section is an example for that). In a nutshell, the count will be shown on "Following" tab only when you follow people.
I hope that this post is useful to you. If you like this post, share with your friends.
