Hreflang Checker — No Uploads Required
A Hreflang validation and reciprocity checker. Enter any URL to fetch its HTML, parse all rel='alternate' hreflang links, and validate your international SEO setup. The tool checks for ISO language/region code validity, self-referencing hreflangs, absolute URL compliance, and allows you to dynamically verify reciprocal links (checking if target pages link back with correct hreflang configurations). Export reports as CSV or print-ready PDFs.

Questions People Ask
Honest answers about how this works.
Why is a self-referencing hreflang tag important?
A self-referencing tag is a requirement in international SEO. Each alternate language version of a page must reference itself as well as the other versions.
What even is reciprocity in hreflang tags?
Reciprocity means if Page A says Page B is its Spanish alternate, Page B MUST link back to Page A as its English alternate. Without reciprocal links, search engines will ignore the hreflang configuration.
What is x-default used for?
Short answer: The x-default hreflang attribute designates the fallback page for users whose language/region matches none of the specified alternates (typically a generic landing page or redirect script).
