What is a meta description tag?
Most search engines extract the contents of the Meta description tag to use as the search result description. Google, AllTheWeb, AltaVista and Inktomi extract the contents of the Meta description tag to use as the description in its search results. We highly recommend including a keyword-rich meta description tag in every optimized web page. If the meta description tag is missing, the search engine will usually extract a description from the first couple of lines of the main body text. The description should be descriptive and sell the page to search engine users, so they click on your link. We put major effort into creating descriptions that are keyword-rich and enticing to search engine users.
