For each URL on my site, I'm auto-redirecting according to header accept language. The site arch isEnglish version: http://mydomain.com/pageSpanish version http://es.mydomaina.com/pageetc..The english version is displayed unless I'm seeing a specific language other than en and that I support in the header, and then a redirect occurs. Google says this: For language/country selectors or auto-redirecting homepages, you  should add an annotation for the hreflang value x-default as well:My pages aren't language selectors, nor are they the homepage. But I am auto-redirecting. My question is, should my english version be hreflang=x-default or/and hrefland=en?
Should the English website use href=x-default when it doesn't auto-redirect to the user's language or country?
