The Description META tag is also an important META tag. You should place one on each page. When someone types keywords in a search engine like Google, the search engine displays the results. When you take a look at the titles you usually see description of the site. We can make those my including this META tag.
      Again META Tags don't need a closing tag. Remember that they are placed within the HEAD element of a page:
< HEAD> < META NAME="Description" CONTENT="Place you nice description here.">
</HEAD>
      Notice first that NAME = "Description" This tells the search bot or a browser that this META tag contains the description for this specific Web page.
      Secondly, notice the CONTENT = "Place you nice description here.". This is the area in which you place the sentence(s) which describes your site in short to people looking at search results. Including keywords in your description tag increases that page's importance.
The Code
So if my webpage was on the Mozart, my description tag would look like this: < META NAME="Description" CONTENT="The biographical look at the great composer and musician - Mozart.">
