How this service works
Prüft am Objekt paginierung den Befund selbstreferenzierende kanonische Adresse.
Output
Returns an audit finding indicating whether the given pagination URL contains a self-referencing canonical tag (i.e., a canonical link element pointing to the page's own URL), including the detected canonical URL value and whether it matches the requested URL.
Example use cases
Audit pagination canonical tags for e-commerce
“Check whether https://shop.example.com/products?page=3 has a canonical tag that points to itself — I want to confirm we're following SEO best practices for paginated product listings.”
Diagnose canonical confusion on a blog
“Can you verify if https://myblog.com/articles?p=5 has a self-referencing canonical? I think our CMS might be outputting the wrong canonical on paginated pages.”
Validate canonical implementation before site launch
“Before we go live, can you check that https://staging.example.com/news/page/2/ has a canonical tag that correctly points back to itself, not to the first page?”
Technical details
Endpoint
POSThttps://crawlspur.halowerk.com/v1/pruef/crawlspur/canonical-selbst/paginierungWhen to prefer
Use this endpoint when you specifically need to verify that a paginated page carries a self-referencing canonical tag as part of an SEO audit. Prefer this over generic HTML scrapers when you need a structured pass/fail finding specifically for canonical self-reference on pagination objects, without building your own HTML parsing logic.
Side effects
- URL is not publicly accessible, returning a network or HTTP error
- Page does not contain any canonical tag, resulting in a missing/null finding
- CSS selector matches no element or returns an ambiguous result
- URL is malformed or exceeds max length of 2048 characters
- Target page returns a non-HTML response (e.g. PDF, redirect loop)
- Domain or IP not publicly resolvable
