No keywords
The inclusion of keywords in a meta tag is likely
to improve the chances of people finding your site in a search engine.
The Problem
When listing or rating a web site, many search engines include the keyword
list in calculations that determine when a site is listed, and what rating
it will be given. If you wish to maximize your exposure through search
engines, you need to include sensible keywords.
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>Ozone</title>
</head>
<body>
<h1>Ozone</h1>
<p>This page is all about ozone.</p>
</body>
</html>
The Fix
The standard way to add keywords is within a meta tag, in the head section
of the document.
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>Ozone</title>
<meta name="keywords" content="ozone, o3, oxygen, atmosphere,
UV, CFC">
</head>
<body>
<h1>Ozone</h1>
<p>This page is all about ozone.</p>
</body>
</html>

versions of HTML, including XHTML.

Exceptions
If your web site is not intended to be listed in a search engine (for
example, some intranet sites) then you can safely disable this advice.
No description
The inclusion of a description in a meta tag is likely to improve the
chances of people viewing your site after finding it in a search engine.
The Problem
When listing a web site in response to a user's search, many search engines
display the description from the meta tag. If well-worded, this description
will help convince a user to visit this page instead of the ones listed
above and below it.
