About Schema Validator

Paste JSON-LD, enter a URL or upload an HTML file to instantly validate structured data against Schema.org and Google Rich Results requirements. The validator parses JSON syntax, checks every required and recommended property for 19 schema types, detects invalid URLs and dates, flags duplicate properties, and reports Rich Results eligibility for FAQ, Product, Recipe, Event, Article, Breadcrumb, Video and JobPosting. An overall validation score (0–100) surfaces errors, warnings and recommendations with suggested fixes. Export the full report as JSON, TXT or PDF.

Frequently Asked Questions

Structured data is a standardized format for providing information about a page and classifying its content. When added to HTML as JSON-LD, Microdata or RDFa, it allows search engines to understand the page's content precisely — powering rich results in Google Search such as star ratings, FAQs, recipe cards and event listings.

JSON-LD (JavaScript Object Notation for Linked Data) is Google's recommended format for structured data. It goes inside a <script type='application/ld+json'> tag in your HTML and describes the page's content using Schema.org vocabulary. It is easy to add without changing visible markup and is parsed independently from the rest of the HTML.

Invalid structured data is simply ignored by Google — it does not trigger rich results and may even cause manual actions for misleading markup. Common issues include missing required properties, incorrect date formats, invalid URLs and wrong data types. Validation catches these before you publish, ensuring your markup actually powers rich results.

Google Rich Results are enhanced search result formats powered by structured data — star ratings under product listings, expandable FAQ sections, recipe cards with cooking time and calories, event date chips, breadcrumb trails, and more. They increase click-through rates by making search listings more visually prominent and informative.
