如何使用 Hreflang Validator
Enter an hreflang code and validate whether it matches the expected locale-style syntax used in multilingual SEO workflows. This tool is useful when checking tags for international sites, alternate language pages, and region-specific content variants. It is designed as a fast syntax validator rather than a full crawl-based hreflang audit.
1
Enter the hreflang code
Add a code such as en, en-us, or fr-ca that you want to validate.
2
Run validation
Check whether the submitted code matches the expected hreflang syntax pattern.
3
Review the result
Confirm whether the code looks valid before using it in markup or page logic.
4
Apply it carefully
Use the validated code in hreflang tags, alternate URLs, or international SEO documentation.
