JSON-LD vs Microdata vs RDFa: Which Structured Data Format Google Prefers in 2026

Google officially recommends JSON-LD over Microdata and RDFa. Here's why it matters — and a side-by-side comparison of the same Article schema in all three formats.

  • Google officially recommends JSON-LD and calls it 'easier to implement and maintain' — for new implementations, there is no reason to choose Microdata or RDFa.
  • JSON-LD is the only structured data format that works reliably with JavaScript-rendered content — Microdata and RDFa require the HTML DOM to be present, which SPAs and Next.js don't guarantee at crawl time.
  • Microdata lives inside HTML attributes which means any HTML restructuring or component refactor breaks the schema silently — JSON-LD in a separate script tag is immune to layout changes.
  • RDFa is effectively dead for SEO purposes in 2026 — it survives in academic and government linked data applications but Google processes it less reliably than JSON-LD.
