Hreflang validator

One page missing x-default fails alone. A lopsided cluster goes unnoticed until traffic splits. Paste the cluster, see which side is missing.

What it checks

Fetches up to 10 cluster pages and checks self-reference, x-default and reciprocal links.

Per-page canonical self-reference and x-default, cross-page reciprocal hreflang pairs.

How verdicts work

pass means self-ref plus x-default on every page plus reciprocal links; missing pieces fail with the offending pages named; dead members fail the cluster — the URLs are your hand-picked set, so silence is not an option.

Reads the no-JS response only, never runs JS. One run counts as one check, not per URL.
