x-default specifies the fallback page for users whose language/region doesn't match any of your other hreflang entries — often a language selector or your primary version.

Q: What is an hreflang tag?

hreflang tags tell search engines which language and region each version of a page targets, so the right version is shown to the right users. They use codes like en-US, es-ES, or fr-CA.

Add each language/region version of your page and get valid hreflang link tags (plus x-default) — so Google and AI show the correct version. Copy & paste into your <head>.

Language / region versions

Use codes like en, en-US, es-ES, fr-CA. Add an x-default fallback. Every page should list all versions including itself.

hreflang tags

Paste into the <head> of every language version (the set must be identical & reciprocal on each page).

How hreflang works

hreflang tags tell search engines which language and region each version of a page targets, so a French user gets your French page and a US user gets your US page. The rules: list all versions (including the current page) on every page, make the references reciprocal (each page points to the others), and add an x-default for everyone else. Getting this right prevents duplicate-content confusion and helps AI engines surface the correct version.
