How this service works
Prüft am Objekt video den Befund selbstreferenzierende kanonische Adresse.
Output
Returns a structured finding indicating whether the video page at the given URL has a self-referencing canonical tag, including the detected canonical URL value and a pass/fail verdict on whether it matches the target URL.
Example use cases
SEO audit for video landing page
“I just published a new video page at https://mysite.com/videos/tutorial-intro — can you check whether the canonical tag on that page correctly points to itself? I need to make sure there are no canonical issues before I submit it to Google.”
Detect canonical mismatch on video content
“We have a video at https://shop.example.com/product-video?ref=promo and I'm worried the canonical might be pointing to the wrong URL. Can you verify whether it has a self-referencing canonical set up correctly?”
Bulk SEO review workflow for video pages
“As part of our weekly SEO check, please inspect https://media.brandsite.com/watch/episode-5 and confirm whether the canonical tag there references the page itself — flag it if it doesn't.”
Technical details
Endpoint
POSThttps://crawlspur.halowerk.com/v1/pruef/crawlspur/canonical-selbst/videoWhen to prefer
Use this endpoint when you need to programmatically verify that a specific video page's canonical tag points back to itself — particularly useful in technical SEO audits, CI/CD pipelines for content sites, or automated monitoring of video content pages. Prefer this over generic HTML parsers when you want a structured pass/fail SEO finding without building custom extraction logic.
Side effects
- URL is not publicly accessible or returns a non-2xx HTTP status
- Video page does not contain any canonical tag — finding returns absent/missing
- CSS selector provided matches no element on the page
- Canonical URL found but points to a different resource — flagged as non-self-referencing
- Malformed or invalid URL supplied in the ziel field
- Timeout or network error reaching the target URL
