Schema Tools
Schema tools are utilities used to validate and test structured data markup that helps search engines display rich results.
Verification Focused Utilities
This category is intended for developers, SEO professionals, and technical teams who need to ensure that structured data is correctly implemented and eligible for search engine features. The tools focus on technical validation and compliance with established schema standards.
Each tool in this category performs checks against structured data markup. This allows users to identify syntax errors, confirm required properties, and test whether their pages meet the criteria for specific rich result types.
What problems this category solves
Solving complex schema validation challenges
Invalid JSON-LD or Microdata syntax
Missing required properties for rich results
Difficulty identifying which schema types are present on a page
Unclear eligibility for Google rich results
Manual debugging of complex structured data nesting
Incorrect implementation of Schema.org vocabulary
How to use these tools together
These tools can be used to validate both the syntax and the functional eligibility of your markup. For example, you may first use the checker to find errors in your schema code, and then use the rich results test to confirm that Google will recognize the specific data for search features.
Each tool addresses a different level of verification. You can use them individually for targeted checks or together for a comprehensive structured data audit.

Limitations and expectations
These tools evaluate technical compliance and eligibility. They do not guarantee that rich results will appear in search results, as Google determines display based on many factors.
Validation reports reflect current standards and documentation. Search engines may update their requirements, and results should be verified against official search console reports.
The tools analyze the markup provided in HTML or code snippets. They do not account for external data sources or broader site-wide structured data relationships.
Frequently asked questions
What is the difference between schema and rich results?
Schema is the underlying vocabulary used for structured data, while rich results are the visual search features (like stars or carousels) that Google displays using that data.
Will these tools fix my schema automatically?
No, they are for analysis and validation. They identify errors so that you can correct them in your code.
Is JSON-LD the preferred format for schema?
Yes, Google generally recommends using JSON-LD for structured data implementation.
Do I need to be a developer to use these tools?
While they provide technical details, they are designed to be accessible to anyone reviewing structured data implementations.
