## Solution

JSON-LD structured data helps search engines understand your content and can unlock rich results. Validate against schema.org rules (headline, author, datePublished for articles, name/url for organizations, etc.) and keep the JSON well-formed. Use SquirrelScan's built-in schema validator to expose the exact missing property path before verifying on Google's Rich Results Test, and ensure each required field points to a canonical resource.
