Specifically tests for Google Rich Results eligibility
Detailed explanations and fix examples
Unlike basic schema checkers, we specifically test for Google Rich Results eligibility. We don't just validate syntax – we tell you if your markup will actually trigger enhanced search results.
Result: You know exactly which rich features (stars, prices, images, etc.) your markup will enable.
Other schema checkers give cryptic error messages. We provide detailed explanations with specific fix examples. No more guessing what "invalid property" means.
Example: Instead of "missing required field," we say "Article markup needs 'author' property. Add: "author": {"@type": "Person", "name": "Author Name"}
Most schema checkers only handle JSON-LD. We validate JSON-LD, Microdata, and RDFa – covering all structured data formats you might encounter.
Practical benefit: Check markup from any source – WordPress plugins, custom implementations, or third-party tools.
Found in 60% of checked sites. Products without prices, articles without authors, events without dates.
Found in 45% of sites. Schema claims 5-star ratings but page shows 3 stars. Google penalizes this.
Found in 35% of implementations. Using text where numbers are required, wrong date formats.
Found in 50% of "valid" markup. Technically correct but missing properties needed for rich results.
Use our comprehensive schema checker to validate your markup and optimize for rich results.
