I am confused about hreflang=x-default.I have a site in 2 languages. In each page I have a link to the page itself and a link to the same page in the other language. If I understand correctly, I have to put an x-default also. In my case it goes to the page language. There the user can see two buttons to choose the language of the site.The x-default link is the same on all pages and it is present in all of them. <link rel=alternate hreflang=en href=http://example.com/about /> <link rel=alternate hreflang=fr href=http://example.com/fr/about /><link rel=alternate hreflang=x-default href=http://example.com/language />I use Screaming Frog to detect possible errors. It says Missing confirmation links in all the pages when I see the details of the error. It makes reference only to the x-default link. I do not understand.How to use the hreflang=x-default?
