MULTILINGUAL · HREFLANG

hreflang Cluster Builder

Build a valid <link rel="alternate"> cluster with x-default fallback. Built-in validation for the common mistakes.

💡 Add one row per language. Include x-default as the fallback. RTL languages (Arabic, Hebrew) follow the same pattern.

About hreflang

hreflang tells search engines which version of your page to serve users in different languages or regions. Get it right and you can dramatically expand your addressable market. Get it wrong and Google serves the wrong version, hurting CTR and rankings.

The rules

Include all language versions, including the one on the current page (self-reference)
Always include x-default as the fallback
Use BCP-47 codes: en, en-US, ar-DZ, fr-FR
Links must be reciprocal — if A links to B, B must link to A
