Overview
Structured data helps search engines understand page content types such as articles, products, FAQs, and organizations. Schema Markup Generator drafts JSON-LD you can paste into your site, and Schema Validator checks syntax against common schema.org patterns.
Validate after every template change—one missing required field can invalidate an entire graph. Pair structured data work with Meta Tag Generator when you are launching a new landing page.
Rich results are never guaranteed; Google chooses when to show enhanced listings based on quality and policy.
How to choose
- Create JSON-LD → Schema Markup Generator.
- Validate existing markup → Schema Validator.
Frequently asked questions
JSON-LD or microdata?
This generator focuses on JSON-LD in script tags, which is the most common modern approach.
Will schema guarantee rich snippets?
No. Valid markup is necessary but not sufficient; search engines decide eligibility.
Can I combine multiple types?
Yes. Use graph arrays or nested nodes; validate the combined output before deploy.
