What does this auditor check?

It checks redirect hops, final status, canonical link tags, meta robots, and X-Robots-Tag headers for one public URL.

Why does canonical mismatch matter?

If the canonical URL points somewhere other than the final destination, crawlers can receive conflicting signals about which URL should be indexed.

What is the difference between 301, 302, 307, and 308?

301 and 308 are permanent redirects. 302 and 307 are temporary redirects. 307 and 308 preserve the HTTP method, while 301 and 302 often do not in browser behavior.

Checks redirect hops, final canonical, meta robots, and X-Robots-Tag for one public URL.

Public HTTP(S) URLs only. Internal hostnames, IP literals, non-standard ports, oversized documents, and overused destinations are intentionally blocked or partially skipped.
