Schema Markup – Definition
Structured data (schema.org vocabulary) embedded in a page's code that helps search engines and AI systems interpret content like products, reviews, and FAQs.
Schema markup for products, reviews, and FAQ content helps both classic search engines and voice or AI answer systems interpret and correctly surface content — a modular CMS can apply it consistently across pages without manual per-page work. Generating schema automatically from the same structured content fields used to render the visible page (rather than maintaining a separate, parallel set of markup) is what keeps it accurate over time, since markup maintained by hand tends to drift out of sync with the actual page content as products change and gets caught by search engine spot-checks that penalize mismatched structured data.
