A web page description is used by search engines to help them determine what a page is about and to help them know what to display in search engine results. The description is not readily visible to the user when visting a page because it is placed in what is called a meta tag. A meta tag is html that is included in the header of a page and basically sits in the background when a page is viewed.
Here is a very simple html example. Note the "professional Web Design - SEO for Descriptions." That text is in the meta tag named "description".
<html>
<head>
<title></title>
<META NAME="description" CONTENT="Professional Web Design - SEO for Descriptions.">
<META NAME="keywords" CONTENT="">
<META name="classification" content="">
</head>
<body>
</body>
</html>
Each page should have a specific topic. The title should be a brief topic title of the page and the description a concise summary or thesis. Web masters want to simply describe what you want people to see in search result and make sure that it relates to what the content of the page says. Choose a few key words and write a couple/few brief sentences. Typically, the more focused the better.
