Alternates in the wrong language
WarningMedium priority
Pages that name an alternate in a language that alternate does not claim for itself.
Why it matters
When two pages disagree about which language a page is in, search engines cannot tell which to show to whom.
How to fix it
Use the same code for a page everywhere it is named, including on the page 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.
