Working on a site where there are loads of canonical urls. Problem is the pages designated as such don`t have any duplicates. This is some automated process the developer put in place. Yoast is installed and doesn`t offer any light on where to manage these pages.
Gerry White: Canonical tags if correctly configured are great, they resolve issues like tracking parameters, case, https duplicate content issues, if they`re good don`t remove them ... what do you see as the problem?
Marc Spindel: They are referring to themselves. I assume that`s the incorrect usage.
