Unlike the
keywords attribute, the description attribute is supported
by most major search engines, like Yahoo and Bing, while
Google will fall back on this tag when information about the
page itself is requested (e.g. using the related: query).
The description attribute provides a concise explanation of
a Web page's content. This allows the Web page authors to
give a more meaningful description for listings than might
be displayed if the search engine was unable to
automatically create its own description based on the page
content. The description is often, but not always, displayed
on search engine results pages, so it can affect
click-through rates. Industry commentators have suggested
that major search engines also consider keywords located in
the description attribute when ranking pages.W3C doesn't
specify the size of this description meta tag, but almost
all search engines recommend it to be shorter than 155
characters of plain text.
