Audit canonical and robots directives across a set of supplied pages together
Audit canonical and robots directives across a set of supplied pages together. Reports a canonical chain, where one page names another that names a third and crawlers do not follow reliably; pages consolidating onto a target that declares noindex; a page declaring noindex while naming itself canonical; an X-Robots-Tag header disagreeing with the markup, where which one wins is not under the page author control; a canonical crossing hosts; and pages with none at all. Nothing is fetched.
