What is Hreflang?

Hreflang (specifically the rel="alternate" hreflang="x" tag) is a signal that tells search engines about the language and geographic targeting of alternate page versions. It ensures users see the right language version in search results based on their location and language settings.

For example, if you have English, Spanish, and French versions of a page, hreflang tags on each version tell Google about all three alternatives. A user searching in French from France would see the French version in results, while a Spanish user would see the Spanish version.

Hreflang tags can be implemented in three ways: as HTML link elements in the page head, as HTTP headers (useful for PDFs and non-HTML files), or in the XML sitemap. The HTML approach is most common and looks like: <link rel="alternate" hreflang="es" href="https://example.com/es/page" />.

Correct hreflang implementation requires: every page referencing all its alternate versions (including itself as a self-reference), using valid language codes (ISO 639-1) and optional country codes (ISO 3166-1 Alpha 2), including an x-default version for users who don't match any specified variant, and ensuring reciprocal confirmation (each referenced page must reference back).

For multilingual or multi-regional websites, hreflang is essential for preventing duplicate content penalties and ensuring the right page version appears to the right audience. Without hreflang, Google might treat language variants as duplicates (suppressing some from results), show the wrong language version to users, or consolidate all versions into one, losing international traffic.
