Hreflang alternate has no return tag

HighNeeds reviewInternationalizationSite-wide checkhreflang_no_return_tag

What this means

This page declares hreflang alternates that the crawl reached and that do not link back to it. Google ignores non-reciprocal hreflang annotations, so the whole language cluster can be dropped.

How to fix it

Make every URL in the cluster list every other URL, including itself, so each annotation is reciprocal.

Fix effort

This check needs review: the change can be drafted for you, but a person has to approve the wording or choose the target before it ships.
