What we validate
✓Return tags
Every page in a cluster links back to the others, in both directions.

✓Language & region codes
Valid ISO language and country codes, with no duplicates per cluster.
✓x-default
A fallback x‑default is present for visitors that don’t match a locale.
✓Page health
Every hreflang URL returns 200 — no redirects, 404s or 403s.
✓Self-reference
Each page references itself within its own set of hreflang tags.
