Hreflang
Hreflang is an HTML or sitemap signal that tells search engines which language or regional version of a page should be shown to users.
What it means
Hreflang is used on multilingual or multi-regional websites to connect equivalent URLs across languages and countries. It helps search engines serve the right version but does not replace translation quality, Canonicalization or Indexability.
Why it matters
It matters because users in different regions may need different language, currency, legal or local content.
Example
A site can connect English, Romanian and German versions of the same product page with reciprocal hreflang annotations.
Common mistakes
Common mistakes include missing return tags, pointing hreflang to non-indexable URLs, mixing canonicals incorrectly or using invalid language-region codes.
