Structured data (JSON-LD) check

Validates schema.org JSON-LD on every crawled page against Google's rich-results eligibility rules.

Quick answer

We extract every JSON-LD block, validate against schema.org, and score against Google's rich-result required/recommended fields.

What it checks

• Valid JSON syntax
• @context is schema.org
• Required fields per type (Article, Product, FAQPage, HowTo, LocalBusiness, Event…)
• Recommended fields (for scoring)
• Conflicting/duplicate types on one page

Where to find it in Lemwatch

How to fix

1. Open the failing page in Google Rich Results Test to see the specific field.
2. Add missing required fields (name, image, etc.).
3. Remove duplicate schemas for the same entity.
4. Re-crawl.

FAQ

Does more schema = better rankings?

No — quality > quantity. Focus on rich-result-eligible types.

Should I use microdata or JSON-LD?

JSON-LD — Google recommends it exclusively.
