Urls go like
but I also have filter page in place that lets you do this
domain/approved/education-entertainment-business/kids/female and so on
which means list all female kids articles no matter what Level1 category they fall in.
But that also means that
list exactly the same content (assuming level2 only has 3 categories - kids, teenager and adult). How to handle duplicacy in this case for the sake of canonical url and so on.
Also, my sitemaps should not worry about filtering URLs (the ones with dashes), right?
