International SEO Hreflang Validator – Free hreflang Tag Checker Tool

When running a multilingual or multi-regional website, ensuring that search engines understand which version of your page to show is critical.
This is where hreflang tags come in. A wrong implementation may cause duplicate content issues, incorrect regional targeting, and lost traffic.

To help SEOs, webmasters, and developers, we built the International SEO Hreflang Validator – a free tool that scans your website and validates all your hreflang tags.

Why Hreflang Tags Matter

Improve International SEO

  • Tell Google which page to serve based on the user’s language or region.

  • Prevents wrong-language pages from appearing in search results.

Avoid Duplicate Content Issues

  • Correct hreflang tags consolidate ranking signals.

  • Ensure different language versions are treated as unique content.

Better User Experience

  • Users land on the right page in their own language.

  • Increases engagement and reduces bounce rates.

Key Features of the Validator

🔍 Detect All Hreflang Tags

  • Crawls <link rel="alternate" hreflang="..."> tags in your HTML.

  • Works with absolute and relative URLs.

✅ Validate Language Codes

  • Checks if hreflang values follow ISO standards (e.g., en, en-us, fr-ca).

  • Detects invalid or malformed codes.

⚡ URL Status Check

  • Verifies if each hreflang URL is reachable.

  • Reports HTTP status codes (200, 301, 404, etc.).

📊 Duplicate & x-default Detection

  • Flags duplicate hreflang entries.

  • Confirms if an x-default tag is present for fallback.

Example: How It Works

Suppose you check https://example.com. The tool finds:

  1. <link rel="alternate" hreflang="en" href="https://example.com/en/" /> → ✅ Valid, Status 200

  2. <link rel="alternate" hreflang="fr" href="https://example.com/fr/" /> → ✅ Valid, Status 200

  3. <link rel="alternate" hreflang="es-us" href="https://example.com/es-us/" /> → ⚠️ Invalid code

  4. <link rel="alternate" hreflang="x-default" href="https://example.com/" /> → ✅ Present

With one scan, you know which hreflang tags need fixing.
