A meta tag is a coding statement in the Hypertext Markup Language (HTML)
which is the basic language of the Internet. It describes some aspect
of the contents of a Web Page.
The information provided 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.
