Validating Schema Markup for Rich Search Snippets
Structured data (JSON-LD) enables search engines to parse key entities, author bylines, FAQs, product ratings, and how-to steps directly from your web pages. Validating your schema markup ensures that your pages qualify for Google Rich Results and prevents critical parsing errors that could disqualify your site from SERP features.
