Canonicalised
WarningMedium priority
Pages whose canonical names a different address, so they ask not to be indexed themselves.
Why it matters
The page gives its place in search results to another. That is right for a duplicate and wrong for a page meant to be found.
How to fix it
If this page should be found on its own, point its canonical at itself.
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.
