Schema Analyzer

A schema analyzer fetches a page's HTML and finds every JSON-LD structured data block on it — the <script type="application/ld+json"> tags search engines read to understand your content — then reports which schema.org types are present and whether each block's JSON is valid enough for search engines to actually use.

Structured data doesn't directly boost rankings, but it's what lets Google show rich results — star ratings, breadcrumbs, FAQ dropdowns, event dates, and more — directly in search listings. Pages with well-implemented, valid schema markup tend to stand out and earn more clicks than plain blue-link results.

Search engines silently skip the entire block. Even one misplaced comma or unescaped quote makes the whole thing unparseable, so you lose every rich-result benefit that schema was meant to unlock — often without any visible warning unless you specifically check for it.

It depends on the content: Organization and WebSite are common on a homepage, Article or BlogPosting for posts, Product for e-commerce listings, BreadcrumbList for navigation, and FAQPage for FAQ sections. There's no single required type — the right one matches what the page is actually about.

No — it checks JSON-LD specifically, which is Google's officially recommended format and by far the most common way structured data is implemented today. If a site still uses older microdata or RDFa markup embedded in HTML attributes, this scan won't detect it.
