The page responds successfully and no noindex directive, redirect or canonical to another URL was found. It does not mean a search engine has indexed it.
Not eligible
A blocker was found: an error response, a redirect, or a noindex directive. A canonical pointing elsewhere is counted here too, but it is only a hint.
Could not assess
A timeout, blocked fetch, unfinished JavaScript rendering or conflicting canonicals meant the page could not be judged either way.
Canonical points elsewhere
A hint, not a blocker: the page names another URL as the preferred version, and search engines may or may not follow it.
Issues found
Errors and warnings, counted once per page and check.
