JSON-LD vs. Microdata vs. RDFa: Why JSON-LD Wins
- •Three formats: Microdata, RDFa, JSON-LD.
- •Microdata and RDFa = inline. Sprinkle attributes into HTML elements.
- •Problems: (1) Tightly coupled to theme (switch theme = broken data), (2) Nearly impossible to represent nested relationships, (3) Debugging scattered vs. one place.
- •JSON-LD: standalone block in page head. Single script tag. Completely decoupled from visual HTML.
- •Theme changes, page builder edits, CSS overhauls = zero impact.
- •Google publicly prefers JSON-LD. Rich Results Test parses it more reliably.
- •Rankomata outputs exclusively JSON-LD for best practices and future compatibility.
