Bulk Indexability Checker (noindex, X-Robots-Tag, canonical)

Both carry the same directives, but the meta tag lives in the HTML while X-Robots-Tag is an HTTP response header. The header applies to any resource — PDFs, images — and is usually set in the server or CMS config, which is why pages sometimes carry it with no visible meta tag. This tool checks both.

Not the page itself: a nofollow in the page-wide robots tag asks crawlers not to follow its outgoing links. The page can still be indexed and shown. noindex is the directive that removes the page from search — the report flags both separately.

When the canonical link points somewhere other than the final URL of the page itself (after redirects). That is sometimes intentional — duplicate parameters, syndicated copies — but on pages meant to rank on their own it usually means a template bug, so the report marks the mismatch for review.

Yes — the tags are read from the final page after following redirects, exactly like a crawler does. The final URL is shown in the report so you always know which page was actually inspected.

Yes. X-Robots-Tag headers apply to any file type and are reported; meta tags and canonical are only read when the response looks like HTML, so for a PDF you get the header-based verdict.
