Hreflang
Hreflang is an HTML attribute that tells search engines which language and region each version of a page is for, so searchers see the right version.
When you need it
Only if you have the same content in several languages or for several regions, such as English for the US and UK with different pricing. A single-language site doesn't need hreflang.
Rules to get right
- Every version must list all the others, and itself.
- Use valid language and region codes, such as en-us or de.
- Add an x-default for visitors who match none of the versions.
Frequently asked questions
