What is the X-Robots-Tag?
X-Robots-Tag is an HTTP response header that can provide robots directives for documents and resources where an HTML meta tag is not suitable.
How to check X-Robots-Tag
Paste the header value returned by your server. The checker identifies common directives such as noindex, nofollow and nosnippet.
Why check this header?
HTTP robots directives can affect indexing even when the HTML source looks normal. Check them when troubleshooting unexpected indexability issues.
Note: This version analyzes a pasted header value. It does not make cross-origin requests or require an API.
