When to use Hreflang Checker
Inspect the hreflang declarations visible on one page.
Use this check when you need a focused answer about the specific signal described above rather than a broad, unexplained SEO score.
Crawl & indexing
Hreflang Checker
Fetch a page and list declared hreflang alternates and resolved target URLs.
Uses a protected server check
Run the tool
Only public web targets are accepted. Private and reserved network ranges are blocked.
What this check means
This checks declarations on the inspected page; reciprocal validation across an entire site is outside this first bounded version.
Because website responses can change by time, location, resolver, or server configuration, treat the result as a current observation of the submitted public target.
