# What Are Structured Data and schema.org?

Structured data is machine-readable markup that describes entities and page content; schema.org provides the shared vocabulary.

## Why it matters

It helps search systems understand products, organizations, articles, breadcrumbs, FAQs, and other concepts, and can enable supported rich-result eligibility.

## How to use it

Use JSON-LD where practical, mark up only visible and accurate content, select the most specific relevant type, and validate with Google and schema.org tools.

## Limits and interpretation

Markup does not guarantee a rich result or AI citation. Unsupported types can still be semantically useful but should not be marketed as Google features.

## Common mistakes

Adding fake reviews; marking up hidden text; using unrelated types; duplicating conflicting entities; treating schema as a ranking shortcut.

## Questions people also ask

## Where GSC Pulse fits

GSC Pulse uses this concept inside a decision workflow and links to the underlying evidence instead of presenting the term as a decorative metric.
