What are Meta tags in HTML ?

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. The information that you provide in a meta tag is used by search engines to index a page so that someone searching for the kind of information the page contains will be able to find it. The meta tag is placed near the top of the HTML in a Web page as part of the heading.

So the code to a meta tag will look something like this:
<title>My first web page </title>
<meta name="description" content="Awesome Description Here">
<meta http-equiv="content-type" content="text/html;charset=UTF-8">

The basic diference between tittle tag and meta tag is that the title tag is a required page "element" according to the W3C. Meta tags are optional page descriptors.
