If you are taking about your facebook profile page.
You cannot come to know about people visiting your facebook profile without a tracking software.
This is a trivial question that is asked by many teenagers nowadays.
the answer to your question is that you cannot track people who are like checking out your profile in the facebook unless you have a tracking software.
But you can avoid unknown people from checking out your profile on facebook by going to privacy settings and updating your requests.
I hope that helps for securing
your face book identity from strangers.
Best of luck.
