Metatags are one of the top methods search engines
use to rank your website.
Meta elements are HTML or XHTML elements
used to provide structured metadata about a web
page. Such elements must be placed as tags in
the head section of an HTML or XHTML document.
Meta elements can be used to specify page
description, keywords and any other metadata not
provided through the other head elements and
attributes.
The meta element has four valid attributes:
content, http-equiv, name and scheme. Of these,
only content is a required attribute.
Meta Tags An HTML tag that contains descriptive
information about a webpage and does not appear
when the webpage is displayed in a browser. A word
that is in a metatag of a webpage will cause that
webpage to turn up as a result of a search engine's
search on that word, even if that word is not found in
the webpage as viewed in a browser.
