How this service works
Inventory one public page's canonical URLs, hreflang alternates, indexing directives, navigation relations, viewport, referrer policy, and invalid link references.
Output
Returns a structured snapshot of the target page including declared canonical URL(s), all hreflang alternate entries with their lang/region codes and href values, robot indexing directives (e.g. noindex, nofollow, noarchive), navigation relation links (rel=prev/next/canonical), viewport meta content, referrer policy value, and a list of any invalid or malformed link references found on the page.
Example use cases
International SEO hreflang audit
“Check https://www.acmeshop.com/fr/categorie/chaussures for all hreflang alternate tags and canonical URL so I can verify our international SEO setup is correct.”
Detecting accidental noindex on live page
“Can you inspect https://www.myblog.com/2024/best-laptops and tell me what indexing directives it has — I want to confirm it's not accidentally set to noindex.”
Pagination relation tag check
“Look up https://news.example.com/archive?page=3 and pull out any navigation relation tags like rel=prev and rel=next, plus the viewport and referrer policy, so I can make sure pagination is wired up correctly.”
Technical details
Endpoint
GEThttps://trinity-throw-thursday-gravity.trycloudflare.com/x402/seo-directivesWhen to prefer
Use this endpoint when you need a fast, structured technical SEO audit of a single public page's canonical and hreflang setup, indexing signals, and link reference validity — especially for international SEO verification, diagnosing indexing issues, or checking pagination signals. It is more focused and cheaper than a full crawl, and better suited for per-page spot checks than sitemap-level audits.
Side effects
- Invalid or non-HTTP URL returns a validation error
- Target page returns a non-200 status (404, 403, 5xx) resulting in no data extracted
- Page behind authentication or bot protection may return empty or partial results
- Extremely large pages may be truncated to the configured limit
- Malformed HTML may cause incomplete extraction of meta directives
- Network timeout if the target server is slow to respond
