Schema markup

Updated Feb 9, 2026

Definition

Schema markup is structured data (usually in JSON-LD format) added to a page to help search engines understand the content type, entities, and relationships.

Plain English

It's metadata that tells machines "this page is a Product/Article/FAQ/Recipe" with specific properties.

Why it matters

  • Enables rich results (stars, FAQs, prices) in search.
  • Helps AI systems understand page type and entities.
  • Reduces ambiguity when content is retrieved for answers.
