HTML meta tags used in head section of HTML document.HTML metadata lets you specify information about a document rather than document content in
a variety of ways. the meta element can be used to include name of the author, description of the page, keywords,etc..
the <meta> tag is an empty element and so does not have a closing tag, rather,<meta> tags carry information within attributes, so you need a
forward slash character at the end of the element.
meta tag is a very imprortant part of the web. meta tags can assist search engines (Google, Yahoo, Bing,etc....) in finding the best match when a
user performs a search. search engines will often look at metadata included on web page. search engines gives rank to your web depends which keywords you're using. search engines rank it higher than another page with less relevant metadata, or with no metadata at all.
