Removing user fields [duplicate]

How To Add Custom Form Fields To The User Profile Page?

I’m current removing some user fields with the following code in the functions.php file:

function adjust_contact_methods( $contactmethods ) {
  unset($contactmethods['aim']);
  unset($contactmethods['jabber']);
  unset($contactmethods['yim']);
  unset($contactmethods['twitter']);
  return $contactmethods;
}
add_filter('user_contactmethods','adjust_contact_methods',10,1);

I’d like to additionally remove the website and Google+ fields, but I can’t find the correct keyword. Any advice?

unset($contactmethods['googleplus']);

Is what I needed to add to my above code.
