How this service works
Prüft am Objekt canonical den Befund Wert des X-Robots-Tags.
Output
Returns the value of the X-Robots-Tag HTTP response header found on the specified canonical URL, indicating any crawl or indexing directives (e.g. noindex, nofollow, none) present on that object.
Example use cases
Canonical page noindex audit
“Can you check the X-Robots-Tag on the canonical version of https://shop.example.com/product/shoes and tell me if it has any noindex or nofollow directives that would block search engines?”
Pre-launch SEO header check
“Before we go live, inspect the X-Robots-Tag value on https://staging.mysite.com/about — I need to make sure it won't be blocking indexing in production.”
Diagnose disappearing canonical from Google
“Our canonical page https://blog.example.com/top-article suddenly dropped out of Google's index — can you check if the X-Robots-Tag header is sending a noindex signal on that canonical URL?”

Endpoint
POSThttps://crawlspur.halowerk.com/v1/pruef/crawlspur/x-robots/canonicalWhen to prefer
Use this endpoint when you specifically need to audit the X-Robots-Tag HTTP response header on a canonical URL object for SEO purposes. It is distinct from meta-robots checks (which inspect HTML head tags) and is targeted specifically at the canonical object type, making it the right choice when diagnosing indexability issues caused by server-level response headers on canonical pages.
Side effects
- Target URL is unreachable or returns a non-200 HTTP status
- URL is not publicly accessible (private/intranet)
- No X-Robots-Tag header present on the canonical object
- Invalid URL format or URL exceeds maximum length
- CSS selector matches no element or multiple elements unexpectedly
- Network timeout when fetching the target URL
