# Hreflang Check

Finds the multilingual mistakes that make search engines treat one site as three duplicates — missing return links, wrong locale codes, canonicals pointing at the wrong language.

Hreflang fails silently. Nothing breaks on the page, and you find out months later when the wrong language ranks in the wrong country. This scans every published URL for the four mistakes that cause it: a missing return link, a locale code that is not valid BCP-47, a canonical pointing at another language, and a page that lists a translation that does not exist. Free, and it does not phone home.
