Schema.org Structured Data

Overview

Schema.org structured data provides machine-readable page context to search engines via JSON-LD. Enables rich results (stars, FAQs, breadcrumbs, product cards) in SERPs. Implementation is O(1) per page — it's a markup task, not computational.

When to Use

Trigger conditions:

• Adding rich snippet eligibility to web pages
• Implementing product, article, FAQ, HowTo, or event markup
• Debugging Google Search Console structured data errors

When NOT to use:

• When optimizing page content or keywords (use content SEO)
• When improving page speed (use Core Web Vitals optimization)
