Schema.org & JSON-LD Basics
Learn microdata vs JSON-LD and how Sourcer detects both so you can confirm structured data in live HTML.
Structured data helps search engines understand entities on a page. Sourcer scores schema presence for both classic microdata (itemtype) and modern JSON-LD — see our score guide.
Microdata vs JSON-LD
- Microdata — attributes mixed into HTML
- JSON-LD — a
<script type="application/ld+json">block (preferred for most sites)
Practical tips
- Mark up what users can see — do not invent FAQs or reviews
- Prefer one clear primary type per page unless you have a defined graph
- Pair with correct canonicals and crawl directives
- Re-scan after theme updates; many plugins inject schema only in production
Confirm the raw markup with View Page Source.
