How this service works
Prüft am Objekt robots-datei den Befund Wert des X-Robots-Tags.
Output
Returns the X-Robots-Tag header value found on the robots.txt resource at the specified URL, indicating what crawl directives (e.g. noindex, nofollow, none, nosnippet) are being communicated via HTTP headers on that file.
Example use cases
SEO audit X-Robots-Tag header
“I'm doing a technical SEO audit — can you check whether https://shop.example.com/robots.txt is sending any X-Robots-Tag headers that could be accidentally blocking search engine indexing?”
Pre-launch crawlability check
“Before we launch our new site at https://staging.mysite.com, can you verify whether the robots.txt file there has any X-Robots-Tag headers set that might interfere with Google's ability to crawl and index us?”
Monitor competitor robots.txt directives
“Can you check what X-Robots-Tag value is present on the robots.txt file at https://competitor.com/robots.txt? I want to know if they're using any unusual crawl directives via that header.”
Technical details
Endpoint
POSThttps://crawlspur.halowerk.com/v1/pruef/crawlspur/x-robots/robots-dateiWhen to prefer
Use this endpoint when you specifically need to inspect the X-Robots-Tag HTTP response header on a robots.txt file (not the robots.txt directives themselves, and not the X-Robots-Tag on a regular HTML page). It is the right choice for technical SEO audits focused on HTTP-header-level crawl directives applied to the robots.txt resource itself.
Side effects
- URL is not reachable or returns a non-2xx HTTP status
- robots.txt file does not exist at the given URL
- No X-Robots-Tag header is present on the response
- Invalid or malformed URL provided
- Target server blocks the crawl request
- URL exceeds 2048 character limit
