What is Structured Data Schema and What is the use of Structure Data Schema?

Most webmasters are familiar with HTML tags on their pages. Usually, HTML tags tell the browser how to display the information included in the tag. For example,

Avatar

tells the browser to display the text string “Avatar” in a heading 1 format. However, the HTML tag doesn’t give any information about what that text string means—”Avatar” could refer to the hugely successful 3D movie, or it could refer to a type of profile picture—and this can make it more difficult for search engines to intelligently display relevant content to a user.

Schema.org provides a collection of shared vocabularies webmasters can use to mark up their pages in ways that can be understood by the major search engines: Google, Microsoft, Yandex and Yahoo!
