Hreflang Tag Validator
Find invalid locale codes, duplicate alternates, and missing x-default tags.
This is static analysis of the content you paste. It does not crawl live pages, verify HTTP responses, or replace Google Search Console and official validation tools.
About this tool
Paste head markup to audit alternate-language links for malformed locale codes, duplicate hreflang values, relative URLs, missing x-default, and canonical conflicts—the classic international SEO pain on r/TechSEO.
