It’s not a required a part of the hreflang tag, however whether it is used, it must be used accurately. Meaning making a web page that serves as a “catch-all” web page the x-default, not a extremely localized web page. The opposite guidelines of hreflang tags additionally apply right here – the x-default URL must be the canonical of itself and will serve a 200 server response.
