Structured Data Validator
Check any web page for structured data markup. Extracts JSON-LD, Microdata, and RDFa, then validates against common Schema.org types. Find missing required and recommended properties that affect your search result appearance.

questions
Which Schema.org types are validated?
Organization, WebSite, Article, NewsArticle, BlogPosting, Product, LocalBusiness, FAQPage, BreadcrumbList, Person, Event, Recipe, VideoObject, and WebPage. Other types are extracted but not deeply validated.
What's the difference between errors and warnings?
Errors mean a required property is missing, which could prevent rich results from showing. Warnings mean a recommended property is missing, which could improve your search appearance if added.
Does it check Microdata and RDFa fully?
It detects and lists Microdata and RDFa items found on the page, but deep validation (checking individual properties) is only done for JSON-LD, which is the format Google recommends.
