Questions about hreflang and language
Common questions about international versions and language tags.
Does hreflang improve rankings on its own?
No. It helps serve the correct version by language or region, but it does not replace content quality, authority, or technical optimization.
Should lang match hreflang?
There should be general consistency. lang describes the language of the document, while hreflang describes available alternative versions.
Is x-default mandatory?
Not always, but it is recommended when there is a global selector, an international homepage, or a default version.
