Unknown Schema.org types
WarningMedium priority
Pages of this site with an item whose type is not a Schema.org type in the rule set.
Why it matters
A misspelt type is ignored by everything that reads it, and so is everything in the item.
How to fix it
Check the type's spelling and case against Schema.org.
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.
