Broken hreflang x-default Maps: When the Fallback URL Points the Cluster the Wrong Way
x-default is supposed to clarify the fallback destination in an international cluster. When it points to the wrong layer, the whole hreflang map becomes harder to trust.
Why x-default maps break
Problems usually appear when the fallback URL points to a selector page, a non-canonical locale page, or an outdated market route that no longer represents the cluster correctly.
How to audit it
Check x-default targets, canonical alignment, reciprocal hreflang sets, and whether the fallback URL still makes sense as the neutral destination for the cluster.
