JSON-LD Validator
Validate JSON-LD structured data from your website
Frequently Asked Questions
What is JSON-LD?
JSON-LD (JavaScript Object Notation for Linked Data) is a structured data format recommended by Google for schema.org markup. It allows search engines to better understand your page content, enabling rich snippets in search results.
Why should I validate my JSON-LD?
Validating JSON-LD ensures that your website's structured data is correct and will be interpreted by search engines. Errors in JSON-LD can prevent rich snippets from appearing in Google results and hurt your site's SEO.
Which schema.org types are supported?
The validator supports major types like Organization, Article, BlogPosting, WebPage, BreadcrumbList, FAQPage, Product, WebApplication, LocalBusiness, Event, Recipe, Course, JobPosting, Review, HowTo and many other schema.org defined types.
How to fix missing required properties errors?
Each schema.org type has required properties. For example, Article needs headline, author and datePublished. Add the properties listed in the errors to your JSON-LD to fix the issues.
Can I have multiple JSON-LD blocks on the same page?
Yes! Google supports multiple JSON-LD blocks on the same page. You can use the @graph format to group multiple items in a single block, or have separate script type=application/ld+json blocks. The validator analyzes all blocks found.
