Missing Hreflang Test Page

This page has content available in multiple languages but does not declare hreflang tags.

Available versions: English (current) | Español | Deutsch

What's wrong?

• Page has translations but no hreflang links in metadata
• Search engines cannot determine language relationships
• Risk of duplicate content penalties
• Users in other regions may not see the correct language version
• No canonical URL specified for language variations

Expected Detection:

Check: hreflang (automatic, detection not yet implemented)

Status: Future Issue

Detection logic would need to:

• Identify pages with similar content in different languages
• Check for presence of hreflang tags in HTML head or headers
• Verify reciprocal hreflang relationships
• Validate language codes (ISO 639-1)

How to Fix:

Add alternates to metadata:

export const metadata = {
  alternates: {
    canonical: "/en/page",
    languages: {
      'en': '/en/page',
      'es': '/es/page',
      'de': '/de/page',
    }
  }
}

Or add link tags to HTML head:

<link rel="alternate" hreflang="en" href="https://example.com/en/page" />
<link rel="alternate" hreflang="es" href="https://example.com/es/page" />
<link rel="alternate" hreflang="de" href="https://example.com/de/page" />

Hreflang Best Practices:

• Use ISO 639-1 language codes (en, es, de, fr, etc.)
• Add region if needed (en-US, en-GB, es-ES, es-MX)
• Ensure reciprocal hreflang links (all pages link to each other)
• Use absolute URLs, not relative paths
• Verify in Google Search Console
