JSON-LD structured data checker
JSON-LD is how you feed rich results — breadcrumbs, FAQ, product, article. Without a block, you get the default blue link even if the HTML is perfect.
What we measure
We parse every <script type="application/ld+json">, count the blocks and list the @type values. Zero blocks is informational, not a fail: plenty of pages rank without schema. It is still the gap that blocks rich results.
What to add
Markup that matches the page: Article on an article, Product on a product, Organization on the homepage. Fake review stars and unrelated types get ignored or worse.
This checker reports what is present. It does not validate against Google's rich-result rules — that is a different, stricter test.
