Rob,
Thank you for such a fantastic and thorough answer. Helped immensely. We are about to move our site to a new host so I am thinking of having them change it all at that point.
So just to confirm, we are going to be changing our canonical domain from https://www. to https://(no www).
I've run many links through the Pro tool and seem to have same or higher PA for each.
I am not sure why, but it seems a little scary to do this :). I think it is because of how much I read about NOT changing domains/URL structure.
Very appreciative!
Kris
