How this service works
Prüft am Objekt news-dokument den Befund selbstreferenzierende kanonische Adresse.
Output
Returns a structured finding indicating whether the news document at the given URL has a canonical tag that references itself (i.e., matches the page's own URL), including details about the detected canonical URL and whether it passes or fails the self-reference check.
Example use cases
News article canonical tag audit
“Can you check if the canonical tag on this news article is self-referencing? The URL is https://www.tageszeitung.de/politik/artikel-123.html — I need to confirm it's set up correctly for SEO.”
Detecting duplicate canonical issues on news content
“I think our news CMS might be setting wrong canonical URLs on article pages. Can you verify whether https://newsportal.example.com/sport/match-report is using a self-referencing canonical or pointing somewhere else?”
Pre-publish SEO validation for news documents
“Before we publish this article, can you run a canonical self-reference check on the staging URL https://staging.meinemagazin.de/wirtschaft/neue-studie to make sure the canonical tag is correct?”
Technical details
Endpoint
POSThttps://crawlspur.halowerk.com/v1/pruef/crawlspur/canonical-selbst/news-dokumentWhen to prefer
Use this endpoint when you specifically need to validate that a news document page has a properly self-referencing canonical URL, which is a common technical SEO requirement. Prefer this over general canonical checkers when the target is specifically a news article or news-type document, and you want a dedicated, focused finding rather than a broad SEO audit.
Side effects
- URL is not publicly accessible (returns non-200 HTTP status)
- Page is not a news document or has no canonical tag
- CSS selector matches no element or multiple elements
- URL exceeds 2048 character limit
- Invalid or malformed URL provided
- Page blocks crawling via robots.txt or server-side checks
