JSON-LD validation • AI-corrected block in 30 seconds

Schema Validator

Audit your structured data against schema.org's required and recommended fields. Claude returns a corrected block you can paste straight back into your page.

Common questions

What is JSON-LD and why does it matter?

JSON-LD is the structured data format Google recommends for rich results — star ratings, FAQ accordions, breadcrumbs, recipe cards, event panels. Get the markup right and your listing takes up more space in the search results; get it wrong and you lose the rich result entirely.

How does the validator work?

If you paste a URL we fetch the page (HTML only, 1.5MB cap) and extract every <script type="application/ld+json"> block. We parse the JSON, then check each @type against schema.org's required and recommended fields. Claude then writes a corrected version of the most-broken block.

Which schema types does it understand?

Organization, LocalBusiness, Person, Product, Article, BlogPosting, NewsArticle, WebPage, WebSite, FAQPage, Question, HowTo, Event, Recipe, Service, BreadcrumbList, Review, AggregateRating, Offer, VideoObject. Other types still get JSON-parse validation plus AI commentary.

Should I still use Google's Rich Results Test?

Yes — always test the final markup in Google's Rich Results Test before deploying. Our validator catches the field-level mistakes; Google decides whether the rich result is eligible in production.
