I installed the Yoast plugin on my site http://adondeirhoy.com since apparently it had canonical issues according to SEOSitecheckup. But what do I place in the blank space? I do write several articles regarding, let's say, any given concert. Each piece has a different title and through inner linking I show the SE's which is the relevant page (anchor page).
Should I place the anchor page url there? I have gone and read on canonical urls but it seems it is not getting through. LOL. Any help would be appreciated.
