How this service works
Prüft am Objekt parameter-url den Befund Wert des X-Robots-Tags.
Output
Returns the value of the X-Robots-Tag HTTP response header found on the specified parameter URL, indicating any crawl or indexing directives (e.g. noindex, nofollow, none) served to search engine bots.
Example use cases
Diagnosing deindexed faceted navigation pages
“Our faceted navigation URLs like https://shop.example.com/shoes?brand=nike&size=42 aren't showing up in Google. Can you check the X-Robots-Tag on that URL to see if it's being blocked via HTTP header?”
SEO audit of parameter URLs before launch
“Before we launch the new filtered product pages, can you inspect the X-Robots-Tag on https://staging.example.com/listings?sort=price&page=2 to confirm it's not accidentally set to noindex?”
Monitoring crawl directives on campaign landing pages
“We're running a paid campaign through https://example.com/landing?utm_source=google&utm_medium=cpc — can you check what X-Robots-Tag value the server is returning for that URL so we know if it's indexable?”
Technical details
Endpoint
POSThttps://crawlspur.halowerk.com/v1/pruef/crawlspur/x-robots/parameter-urlWhen to prefer
Use this endpoint when you specifically need to inspect the X-Robots-Tag HTTP response header on URLs that contain query parameters (e.g. faceted navigation, filtered pages, paginated URLs). Prefer this over general crawlability checks when the target is a parameter-based URL and you want to isolate the HTTP-header-level crawl directive rather than meta robots tags or robots.txt rules.
Side effects
- URL is not publicly accessible — endpoint cannot fetch the page
- URL is malformed or exceeds 2048 characters — validation error
- No X-Robots-Tag header present — result may be empty or indicate absence
- Target server returns non-200 status — may affect header inspection
- Network timeout or DNS resolution failure for the target URL
