Pagination to non-indexable pages
WarningMedium priority
Pages whose next or previous page in a series cannot be indexed - noindex, canonicalised elsewhere, redirecting or blocked.
Why it matters
A series is meant to be read as one list; a page in it that cannot be indexed hides what is listed on it.
How to fix it
Keep every page of a series indexable, with a canonical to itself, and name each by the address it answers at.
Skitter runs this check on every crawl, and lists each page it finds with the evidence: the header, the tag or the link that gave it away.
