What is the difference between Schema.org and Google Rich Results?

Schema.org is an open community specification defining thousands of types and properties. Google Rich Results is a specific subset that Google's search algorithms recognize to display enhanced SERP features like star ratings, FAQ accordions, and sitelinks.

Why is JSON-LD preferred over Microdata or RDFa?

JSON-LD decouples structured metadata from page layout HTML, placing all data in a single script tag that is easier to maintain, dynamically generate, and less prone to breaking during CSS redesigns.
