Hreflang Tags Testing Tool

The Hreflang Tags Testing Tool helps web developers, SEO professionals, and content managers verify and debug hreflang implementations across multilingual or multi-regional websites. It ensures that search engines like Google understand the language and regional targeting of your pages correctly.

The hreflang attribute tells search engines which version of a webpage to display to users based on their language or country preference. Incorrect or missing tags can lead to duplicate content issues, indexing errors, and poor user experience β€” making accurate testing essential for international SEO success.

🌍 Why Use This Tool?

  • Validate hreflang annotations for accuracy and syntax compliance.
  • Ensure proper mapping between canonical and alternate language versions.
  • Detect missing, incorrect, or broken return links.
  • Preview how search engines interpret your multilingual setup.
  • Improve your international SEO and avoid duplicate content penalties.

🧭 How to Use the Hreflang Tester

1

Enter the URL of your webpage that contains hreflang annotations.

2

The tool will fetch the page and automatically detect all <link rel="alternate" hreflang="..." /> tags.

3

It validates each tag’s syntax, checks for valid return links, and highlights missing or invalid entries.

4

Review the detailed report and correct any inconsistencies in your website’s HTML header.

5

Re-test after updating your site until all hreflang entries pass validation.
