x-default

x-default is a hreflang value for a general version not targeting a specific language or region.

Language versions refer to each other

BG, EN and DE page versions connected by reciprocal hreflang annotations.
Each genuine version lists itself and the others with hreflang. x-default can identify a general fallback; it does not translate content.
Text version
  • BG · /bg/page
  • EN · /en/page
  • DE · /de/page

How it works

Use it for an appropriate general page or language selector and retain valid reciprocal alternatives.

Example

Example: A language selector is the general version while bg and en point to real localisations.

Common mistakes

x-default is not a language code and does not translate content.

How can you check this in practice?

In the hreflang set, identify the real general URL intended for users outside specific language variants. Check that it works and participates in consistent annotations. Do not invent a separate URL merely to populate x-default.

Distinctions and limitations

x-default is not a language code and does not translate a page. It can identify a language selector or suitable general version, while bg/en identify specific language alternatives.
