Quick answer#

We extract every JSON-LD block from crawled pages, validate required properties against schema.org, and flag missing recommended types (Organization, BreadcrumbList, Article, Product, FAQPage).

What we check#

JSON-LD parses without errors

Required properties present per @type

Nested @id references resolve

No conflicting duplicate blocks (e.g., two FAQPage on one URL)

Product schema has price + availability when applicable

Where to find it in Lemwatch#

Site → SEO → Structured Data.

FAQ#

Do you support microdata / RDFa?#

We extract them but recommend migrating to JSON-LD — it's Google's preferred format.
