Description Meta Tag Description and Uses:
The description meta tag provides a description of your web pages to search engine spiders. It is most often used for SEO to provide a short (400 characters or less) description of the contents of the page.
The description meta tag is used by search engines to give searchers a little more information about the web page. You should write a different description for every web page on your site. This will help both search engines and the people using them to see the difference between the various pages on your site.
Most external search engines cut off the description under their link results at around 160 characters. So you should make sure that the most relevant and enticing information is in the first sentence or two of your description.

Description Meta Tag Recommended Uses:
The description meta tag is a very desirable meta tag to use. If you don’t have any other meta tags on your web page, you should include this one. When you leave off this tag, search engines will just take any text they find on the web page, which may not be as useful to your customers and so they won’t click on your result.
