Structured data that does not parse
IssueHigh priority
Pages of this site with a JSON-LD block that is not valid JSON.
Why it matters
Nothing can read a block that does not parse, so whatever it says is lost, rich results included.
How to fix it
Fix the JSON — often a trailing comma or an unescaped quote — and check it with a validator.
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.
