What is a schema.org validator?

A schema.org validator checks whether a website's structured data markup follows schema.org specifications correctly. It verifies JSON-LD, Microdata, and RDFa markup to ensure search engines like Google can read and use the data for rich results.

What is JSON-LD and why does it matter for SEO?

JSON-LD (JavaScript Object Notation for Linked Data) is Google's preferred format for structured data markup. It allows search engines to understand your content's context, enabling rich results like star ratings, FAQs, breadcrumbs, and product details in search results.
