What does Meta description mean?

A meta description is a short description of the content of a specific web page written in the HTML code. Search engines may use it as a text snippet in search results below the page title, but there is no guarantee they will always display it; they may create their own snippet based on the search query and page content. The meta description is not a direct ranking factor for search position, but it can influence whether the result catches the user's attention and whether they click on it. It should therefore briefly and accurately describe the page content, be clear, relevant and ideally unique for each important page of a website or e-shop.
