How to use the hreflang generator

  1. Add each language version with its code and URL.
  2. Set x-default for everyone else.
  3. Put the whole set in every version's <head>.

About this tool

hreflang tells search engines that several pages are the same content in different languages, so the right one is shown to each user rather than the wrong one being treated as duplicate content.

The rule that catches everyone out is reciprocity. Every page in the set must list every version, including itself. If page A points at B but B does not point back, search engines discard the annotation entirely — a half-implemented hreflang set achieves nothing rather than something.

Codes are a language, optionally with a region: <code>en</code>, or <code>en-GB</code>. The region part is a country, not a language, which is why <code>en-UK</code> is wrong and <code>en-GB</code> is right — a genuinely common mistake.

x-default names where users of any unlisted language should go, typically a language selector or the international version.

Common uses

  • A site published in several languages.
  • Regional variants such as en-GB and en-US.
  • Pointing unmatched visitors at a language selector.

Frequently asked questions

Does each page need the full set of tags?
Yes. Every version must list every version including itself. Without that reciprocity the annotation is ignored completely.
Is en-UK valid?
No. The region is an ISO country code, and the United Kingdom's is GB. Use en-GB.
What is x-default for?
Users whose language matches none of your versions. It usually points at a language selector or the international edition.
