JSON-LD Schema Validator

For Google

Schema.org JSON-LD is what unlocks Google's Rich Results — the enhanced search listings with star ratings, FAQs, recipes, prices, dates, and more. Pages with valid schema get more clicks (often 30-50% higher CTR) and rank higher than equivalent unmarked pages.

For AI engines

This is even bigger for AEO. ChatGPT, Perplexity, Claude, and Google AI Overviews read schema preferentially when deciding what to cite. A page with rich Article + Author + Organization schema is far more likely to be cited as a source than the same content without schema.

The biggest leverage points

• Article / BlogPosting — always include for content pages with author + datePublished + dateModified
• Organization — establishes your brand as a Knowledge Graph entity
• Person with sameAs — author authority for E-E-A-T (links to Twitter, LinkedIn, Wikipedia)
• FAQPage — surfaces Q&A directly in search and AI answers
• BreadcrumbList — helps AI engines understand your site's hierarchy

How this validator works

We parse your JSON-LD, check syntax, validate @context and @type, then for each known type we check both required properties (Google won't show Rich Results without them) and recommended properties (better Rich Results when present). We currently cover Article, BlogPosting, NewsArticle, Product, Recipe, FAQPage, HowTo, Event, VideoObject, LocalBusiness, Restaurant, Organization, Person, BreadcrumbList, Review, WebSite, WebPage, and SoftwareApplication.

Cross-check with Google's official tool

Google Rich Results Test ↗ is the authoritative source — Google's own crawler reads your page exactly the way it would for the index, then tells you which Rich Result type (if any) you'll be eligible for. Use our tool for fast iteration as you write JSON-LD; use Google's tool for the final go/no-go before deploying.
