As there are many fake applications that suggest to show you how have visited your profile, there is no such way you can due that in Facebook .Exept with a virus installed on your computer. Any way you could track visitors with google analeptics on the old profile with a embedded Google Analytics code in a FBML box on your side bar.
No one will visit your Profile, Why they should ? all your activities are shown in there Wall stream no need to visit a profile one exception is when you add a new Friends and he want to know who you are thats the one and only time some one would visit your profile.
Some stats from a Profile in one year about 2k Friends Hometown in Europe main profile landing page only :
4s: avarage time on Profile
99,4%: New Vistitors
99% : Visitor region USA
Since new FB remove the custom Boxes from Profile there is no more Side bar with custom elements, not anymore possible.
