Why JSON-LD Structured Data Matters
JSON-LD is Google's preferred format for structured data. Correct implementation unlocks rich results — star ratings, FAQs, breadcrumbs, sitelinks — that dramatically increase click-through rates. One missing required field silently disqualifies your page.
What are required vs recommended fields?
Google marks some fields as required — missing them makes you ineligible for rich results. recommended fields improve appearance but won't disqualify you. This tool shows both, clearly labelled.
Where do I paste this code?
Paste inside <script type="application/ld+json"> tags in your page's <head> or anywhere in <body>. Google reads it regardless of placement.
Can I have multiple schemas on one page?
Yes. Use separate <script> blocks for each schema type. Don't nest unrelated schemas — keep one type per block. FAQ + BreadcrumbList on the same page is a common valid combo.
Why use JSON-LD over Microdata?
JSON-LD lives in <script> tags — it doesn't mix with your HTML markup. Easier to maintain, easier to template, and Google explicitly recommends it over Microdata or RDFa.
