A page description is an HTML metadata content type that is placed in the page head and used by search engines and advertises the content of your page.
Your page description is very important. It is often displayed below your page title in search engine results. It also displays when you post a link to the page.
Page descriptions should accurately describe your content and should encourage people to click on your page link. The recommended length of page descriptions is 50-160 characters.
