Unknown Schema.org properties
WarningLow priority
Pages of this site with a property that is not a Schema.org property in the rule set.
Why it matters
A misspelt property is ignored, so what it was meant to say is not said.
How to fix it
Check the property's spelling and case against Schema.org, or remove it.
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.
