Audit rules

Structured Data Invalid

A JSON-LD block (<script type="application/ld+json">) does not contain valid JSON, so search engines cannot read it. In a QuikSEO audit, a failure of this rule has warning severity and counts against the score. Below are the exact condition, its exceptions and the sources behind it, followed by the other rules of the same group.
