Output
Returns a structured finding indicating whether the sitemap object has a self-referencing canonical address, including details about the canonical URL found and whether it matches the page's own URL.
Example use cases
Pre-launch SEO sitemap audit
“Before we launch the new site, can you verify that https://myshop.com/sitemap.xml has self-referencing canonical tags on all its entries so search engines index the right pages?”
Diagnosing indexed duplicate content
“We're seeing duplicate content issues in Google Search Console — can you check if https://blog.example.com/sitemap-posts.xml has correct self-referencing canonical URLs on its sitemap entries?”
Ongoing technical SEO monitoring
“Can you check the sitemap at https://news.publisher.com/sitemap-news.xml to verify the canonical tags are properly self-referential and flag any that aren't pointing to themselves?”
Technical details
Endpoint
POSThttps://crawlspur.halowerk.com/v1/pruef/crawlspur/canonical-selbst/sitemapWhen to prefer
Use this endpoint specifically when you need to audit a sitemap object (sitemap.xml or sitemap index) for self-referencing canonical correctness. Prefer sibling endpoints for checking canonical tags on regular pages, news documents, or parameter URLs. This is ideal for automated SEO pipelines that verify sitemap integrity before or after site launches.
Side effects
- Invalid or unreachable URL returns an error finding
- Non-public or private IP addresses are rejected
- Malformed URL input fails schema validation
- CSS selector matching no element may fall back to first match or return an error
- Sitemap URL that returns non-XML content may cause parse failure
