hreflang has to be mutual: if A claims B, B must claim A. A one-sided declaration is discarded, so the work of adding it earns nothing.
The finding reads:
critical hreflang-no-return this page links to …, and that page does not link back. A one-way link is not “partly counted” — the whole link is discardedMake the link reciprocal: a one-way link is discarded entirely, not counted in part.
Reported per page even when it is common. Appearing on many pages is the nature of this finding rather than evidence of one template defect, so collapsing it would hide real work.
