# Schema.org

> Schema.org is a shared structured data vocabulary used to describe page content in a way search engines understand, helping them interpret context and display rich results.

**Schema.org** is a standardized [structured data](https://nodea.io/en/glossary/structured-data) vocabulary — developed jointly by Google, Microsoft, Yahoo and Yandex — used to describe the content of a page unambiguously in a form search engines can read. Instead of guessing that a fragment is a price, a rating or an event date, the crawler reads it directly from the attached markup, and can then present the content in a richer way.

## How Schema.org works

Schema.org defines a hierarchy of **types** (for example *Product*, *Article*, *Recipe*, *LocalBusiness*, *Event*, *FAQPage*) and the **properties** that describe each one (for a product: name, price, availability, ratings). These descriptions are embedded in the page code in one of three formats: Google's recommended [JSON-LD](https://nodea.io/en/glossary/json-ld) (a data block separate from the visible content), Microdata (attributes on HTML tags) or RDFa. JSON-LD is the most convenient because it does not mix with the presentation layer and is easy to generate dynamically.

When a crawler encounters valid markup, it builds a structured understanding of the page and may qualify it for [rich results](https://nodea.io/en/glossary/rich-results) — with star ratings, prices, recipe preparation times or an expandable list of questions.

## Practical application

An online store marks products with the *Product* type including price and availability, so ratings and price ranges appear in the results. A publisher describes posts as *Article* with author and date, while a local business uses *LocalBusiness* with address and opening hours to support local [SEO](https://nodea.io/en/glossary/seo). Correct implementation is checked with Google's Rich Results Test and in Search Console. The cardinal rule: markup must reflect content visible to the user — tagging data that is not on the page is treated as spam.

### Does Schema.org improve rankings in Google?

Schema.org markup is not a direct ranking factor, but it helps search engines understand your content and qualifies pages for rich results. Rich results increase visibility and click-through rate, which indirectly drives traffic. It is a tool for communicating with crawlers, not a trick for a higher position.
