Website Meta tags provide metadata about your website such as title, keyword, description, etc. Meta tags are used by search engines to understand the website more and help index to provide relevant content in the search results
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.
The <meta> tag defines metadata about an HTML document. Metadata is data (information) about data. <meta> tags always go inside the <head> element, and are typically used to specify character set, page description, keywords, author of the document, and viewport settings. Metadata will not be displayed on the page, but is machine parsable. Metadata is used by browsers (how to display content or reload page), search engines (keywords), and other web services. There is a method to let web designers take control over the viewport (the user's visible area of a web page), through the <meta> tag.
