A meta tag is a tag (that is, a coding statement) in the Hypertext Markup Language (HTML) that describes some aspect of the contents of a Web page.

Meta tags are snippets of text that describe a page’s content for search engines. In other words, meta tags help to organization content and transform human language in machine language

Meta elements are tags used in HTML and XHTML documents to provide structured metadata about a Web page. They are part of a web page's head section. Multiple Meta elements with different attributes can be used on the same page
