Canonical to a redirect
IssueMedium priority
Pages whose canonical points at an address that redirects somewhere else.
Why it matters
A canonical should name the final address. Pointing at a redirect makes search engines work it out, and they may decline.
How to fix it
Point the canonical at wherever the redirect ends up.
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.
