Nofollow page
WarningMedium priority
Pages asking that none of their links be followed.
Why it matters
Every link on the page stops passing value, and anything reachable only through this page may never be found at all.
How to fix it
Remove the nofollow unless it is deliberate. It is rarely what a whole page wants, as against one link.
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.
