What is an hreflang tag checker?

The Hreflang Tag Checker validates the hreflang implementation on any webpage. It checks for correct ISO language and country codes, verifies that reciprocal return links exist on the referenced alternate pages, and identifies common implementation errors that prevent Google from correctly serving your content to international audiences.

Hreflang tags tell Google which language and regional version of a page to show to users in different countries. Incorrect implementation is one of the most common international SEO mistakes — if return links are missing or codes are wrong, Google ignores the hreflang tags entirely and may serve the wrong language version to users.

Why use an hreflang tag checker?

International websites without correct hreflang implementation suffer from users being served the wrong language version, duplicate content signals across language versions, and lost opportunities to rank in specific country search results. Proper hreflang is non-negotiable for any site serving multiple languages or regions.

What is an hreflang tag?

Hreflang is an HTML attribute that tells Google which language and geographic region a page is intended for. It's used to serve the correct language version of a page to users based on their location and language settings.

What is the x-default hreflang tag?

The x-default hreflang tag specifies the fallback page to show when no other hreflang value matches the user's language or region. It's required for complete hreflang implementation.

What are return links in hreflang?

Return links (or reciprocal links) mean that if Page A hreflang-references Page B, then Page B must also have an hreflang tag pointing back to Page A. Without return links, Google ignores the entire hreflang cluster.

Where can hreflang tags be placed?

Hreflang tags can be implemented in three places: the HTML <head> section (most common), the XML sitemap, or the HTTP response header. All three methods are equally valid.

Does hreflang affect rankings?

Hreflang doesn't directly boost rankings but ensures the correct page version ranks in the right country. Without it, you may rank your English page in Germany or vice versa, leading to high bounce rates.
