Hreflang & International SEO Matrix — frequently asked questions
What are hreflang annotations?
Hreflang HTML tags inform search engines about alternate language and regional versions of a webpage so international users are directed to the appropriate localized version.
What is a reciprocal hreflang link?
If page A links to page B as an alternate language version, page B must also link back to page A. Missing reciprocal links cause search engines to ignore the annotations.
What is the x-default hreflang attribute?
The `x-default` value specifies the fallback landing page for searchers whose language or region is not explicitly matched by any localized version.
Which language and country codes are valid?
Language codes must follow ISO 639-1 (e.g., `en`, `es`, `de`) and optional regional codes must follow ISO 3166-1 Alpha-2 (e.g., `en-US`, `es-ES`).
Can I audit hreflang tags on device?
Yes, paste raw HTML containing `<link rel="alternate" hreflang="...">` tags to audit matrices instantly without uploading your files.
