Schema JSON Parse Errors

What This Means

The page contains a <script type="application/ld+json"> block, but the JSON content inside it is syntactically invalid — it cannot be parsed as valid JSON. Common causes: unclosed brackets or braces, trailing commas, unescaped special characters in string values, or template variables that were not resolved before output.

Why It Matters for SEO

A JSON parse error means the entire schema block is discarded by the parser. Search engines cannot read or process any of the structured data on the page. All rich result opportunities from that schema block are lost, even if 99% of the JSON is valid.

What the Platform Checks

The platform extracts each application/ld+json script block and attempts to parse it as JSON. Fires when the parse throws an error.

How to Fix It

• Use Google's Rich Results Test or the Schema Markup Validator to identify the exact error location.
• Common fixes:
• — Check for trailing commas after the last property in objects and arrays.
• — Check for unescaped quotes inside string values — use \" to escape quotes.
• — Verify all brackets and braces are properly matched.
• — Check that template variables have been resolved before JSON is output.
• Validate the JSON with a JSON linter (jsonlint.com or browser console JSON.parse()) before deploying.
