Hreflang Checker
Enter a URL to extract its hreflang tags and check for common configuration issues.
About this tool
This checks format, duplicates, x-default presence, and (for a bounded sample of alternate pages) whether they link back to this page. Return-reference checks are limited to the first few alternates found, and a page that can't be reached is reported as “couldn't verify,” not assumed broken.
Frequently Asked Questions
- What issues does this tool detect?
- Duplicate hreflang values, invalid language/region format, missing x-default, malformed URLs, and missing return links.
- What is a hreflang return link?
- When page A links to page B via hreflang, B is generally expected to link back to A — this tool checks a bounded sample of alternates for that.
- Can I generate hreflang tags with this tool?
- Use the dedicated Hreflang Generator to build tags from language/region and URL pairs.
