Technically, the meta description is an HTML tag that provides information to the document. It is defined as a header element and always goes inside the <head> tag, at the top of the structure of a web page:

The meta title is much shorter in length than the meta description, as it must occupy a single line, so it does not give as much play. It should contain the target keyword of that page and describe its content semantically. There is not much more you can do with so little space.
