Hreflang Tag Generator

Generate hreflang tags for multilingual pages.

hreflang tags
<link rel="alternate" hreflang="en" href="https://example.com/" />
<link rel="alternate" hreflang="es" href="https://example.com/es/" />
<link rel="alternate" hreflang="fr" href="https://example.com/fr/" />
<link rel="alternate" hreflang="x-default" href="https://example.com/" />

Add these to the <head> of every page in the set — and each page should list all alternates including itself. x-default marks the fallback for unmatched languages.

Free hreflang tag generator. Add each language or region and its URL to generate the rel=alternate hreflang link tags, including an x-default fallback, for international SEO. Runs in your browser.

What hreflang solves

hreflang annotations tell search engines that you have multiple versions of a page for different languages or regions, and which version to serve to which audience. They prevent the wrong-language page ranking for a user and reduce the risk of your localized pages being treated as duplicates.

They matter for any site targeting more than one language or country — e.g. English for the US and the UK, or Spanish for Spain and Mexico.

The correct format

Each language version lists every version, including itself. The value is a language code, optionally with a region code:

<link rel="alternate" hreflang="en" href="https://example.com/">
<link rel="alternate" hreflang="en-gb" href="https://example.com/gb/">
<link rel="alternate" hreflang="es-mx" href="https://example.com/mx/">
<link rel="alternate" hreflang="x-default" href="https://example.com/">

Rules:

  • Language uses ISO 639-1 (en, es); region uses ISO 3166-1 alpha-2 (us, gb).
  • Format is language or language-region — never region alone.
  • Add x-default for the fallback page when no version matches the user.

Common mistakes

  • Non-reciprocal tags: if page A points to B, B must point back to A, or the annotations are ignored.
  • Using a country code as the language (hreflang="uk" is wrong; the UK's language is en-gb).
  • Mixing hreflang across canonicalized pages — each URL must be self-canonical.
  • Using relative URLs; hreflang requires absolute URLs.
  • Forgetting x-default, leaving users with no fallback.

Frequently asked questions

Do I need to list every language on every page?

Yes. Each page in a language set must reference all alternates, including itself. Missing return links are the most common hreflang mistake.

What is x-default for?

The x-default value marks the page shown to users whose language or region doesn't match any of your alternates — usually an international or language-selector page.
