A site I work with have recently taken a clone of their .com site to create a Australian version with a .com.au domain.
They're adding in hreflang code to every page on both sites automatically, referencing the site itself, along with the alternative version of that page on the alternative domain.
The trouble is, not every page on the UK site exists on the Aus site, and vice versa.
So they would end up with a page on the UK site containing an href tag to itself, and an href tag to a page on the Australian site that does not exist.
I've advised that they should be editing this so that any page without an alternative on another domain does not contain the hreflang tag, but they are reluctant and want to know how much impact it would have to leave this code on every page.
Does anyone have any examples of implementing the tags in this way, or suggestions of what the impact might be?
