When is hreflang needed?

Use hreflang when the same content is provided in multiple languages or regional versions, such as Korean, English, and Japanese, so search engines can understand the URL for each version.

Basic Example

Korean page: hreflang="ko"
English page: hreflang="en"
Japanese page: hreflang="ja"
Default representative page: hreflang="x-default"

Implementation Notes

hreflang tags should generally be added as the same set to all connected language pages. Absolute URLs starting with https:// are recommended instead of relative paths.

When should x-default be used?

Use x-default when you have a default page, language selection page, or global representative page to show when the user's language cannot be determined.

Should I include self-referencing hreflang?

In general, each language page should include itself along with all alternate language URLs.

What is the difference between language codes and region codes?

en means English in general, while en-US or en-GB can specify a region. If content differs by country or region, using regional codes is recommended.
