what is schema.org structured data

HTML tags are generally familiar to webmasters. An HTML tag usually provides instructions for how the contents of the tag will appear in a browser. In the example above, the string <h1>Avatar</h1> tells the browser that heading 1 format should display the text "Avatar". Although the HTMLtagis not explicit about what this text string means, it can refer to the 3D movie of the same name or refer to a type of profile picture, making it rather tricky for search engines to display relevant results.

Schema.org is a webmaster resource that provides webmasters with a collection of share vocabularies that can be used to mark up their web pages in a manner that is recognized by the major search engines, including Google, Microsoft, Yandex, and Yahoo!

Your web content can be enhanced with the schema.org vocabularies, Microdata, RDF, and JSON-LD formats. As a result of this guide, you will be able to gain a basic understanding of Microdata and schema.org so that you can begin working with markup.

Why is schema.org necessary?

As a joint effort with sitemaps.org, schema.org is designed to help improve the web by creating a schema for structured data markup supported by all major search engines. A search engine's on-page markup aids in understanding the content on a web page and provides a more comprehensive search result. It is easier for webmasters to choose a markup schema with a shared markup vocabulary and achieve the maximum benefit from their efforts.

There are many different types of items in Schema.org, each of which has a set of properties you can use to describe it. In addition to the movie and person types, there are many other items that are also described in Schema.org.

An item has four properties that define it as a Thing: name, description, URL, and image. More specific types also share properties. For instance, a Place is a kind of Thing that is more specific, while a Local Business is a kind of Place that is more specific. The properties of the more particular elements are inherited from their parents.
