Schema Markup Validator

Why You Must Validate Schema

JSON-LD is incredibly unforgiving. A single missing comma, an unclosed quote, or a missing required property can cause Google to silently ignore your entire schema block.

Common Errors This Tool Catches:

• Syntax Errors: If the JSON is malformed, Google cannot read it. This tool parses the raw text to ensure it's valid JSON.
• Missing Required Properties: For example, an Article schema is invalid without headline, image, datePublished, and author.
• Missing Recommended Properties: Properties like dateModified or publisher aren't strictly required, but adding them significantly increases your chances of getting a Rich Result.
