Schema Validator reference
Schema Validator checks JSON-LD structured data so machines can identify the entities, page type, and relationships on a page. It is useful for SEO, rich-result readiness, and AI systems that rely on explicit page facts.
What structured data does
Structured data translates page meaning into a predictable vocabulary. When it is valid and complete, crawlers can understand whether a page describes an organization, article, product, FAQ, breadcrumb trail, website, or local business.
- Detects JSON-LD blocks and schema types
- Highlights parse errors and invalid JSON
- Checks recommended fields for common schema types
- Supports both public URLs and pasted JSON-LD
Why JSON-LD quality matters
Broken or incomplete schema can make otherwise useful content harder to interpret. Valid JSON-LD helps search systems connect page content with entities, navigation, authorship, products, and frequently asked questions.
Best-fit schema types
Most websites should start with WebSite, Organization, BreadcrumbList, and page-specific schema such as Article, Product, FAQPage, or LocalBusiness. The right schema depends on what the page actually represents.
Common questions
Does valid schema guarantee rich results?
No. Valid structured data can make a page eligible for richer interpretation, but search engines decide whether to show enhanced results.
Can I paste JSON-LD directly?
Yes. You can paste JSON-LD to validate it locally through the tool flow without needing to fetch a public page.
Which schema format should I use?
JSON-LD is usually the easiest format to maintain because it can be placed in a script tag without changing visible page markup.
