Inspect language alternates, reciprocal references, canonicals, and x-default, then copy repair-ready hreflang tags.
Inspect actual hreflang in the HTML response, not just the visible page.
No sign-in or email required.This checker reads hreflang annotations from a bounded set of public HTML responses and compares self-references, reciprocal references, duplicates, canonicals, and x-default coverage. When a usable set exists, it also produces copyable link tags so the repair can start from observed URLs rather than an invented language map.
Start with the items that change whether international targeting can work at all. Confirm the evidence on the live page or source file, make the smallest safe correction, and run the same check again after publishing.
A warning is not automatically a defect. Compare it with the page purpose, the intended audience, the available first-party evidence, and the rest of the site before changing a template that may affect many URLs.
Treat the output as a decision aid, not a ranking promise. Keep a record of the change, allow the relevant crawler or reporting period to update, and compare the business or search outcome with the baseline.
