Using META Tags:

This tag will send messages to search engines about your page. These tags should be kept within the <head> and </head> tags. The syntax of the tag is:

<META NAME=name CONTENT=content>

where the name attribute is the name of the tag and the content attribute contains the text you want to put in the tag.

There are several meta tags, but the most important for search engine indexing are the description and keywords tags. The META tag named KEYWORDS provides a list of keywords to the search engine to associate with your web page.

Eg:
<META name="keywords" content="Furniture, ottoman, Lazyboy">

The META tag named DESCRIPTION contains a description of what the search engine will display when it returns the search result to the user.

Eg:
<META NAME="DESCRIPTION" CONTENT="Visit this web site for best furniture ">

Eg:

Suppose you have a web site for selling furniture and  you have a web page (html file) with the following tags in your web page.

<HEAD>
<TITLE>Furniture</TITLE>
<META name="description" content="Visit this web site for best furniture">
<META name="keywords" content="Furniture, ottoman, Lazyboy">
</HEAD>

Now if someone is searching for "furniture" (from a search engine like Yahoo) then under the search results your listing should look like this :
