 It is usually the end part of the URL, which can be interpreted as the name of the resource, similar to the basename in a filename or the title of a page.The name is based on the use of the word "slug" in the news media to indicate a short name given to an article for internal use.Slugs are typically generated automatically from a page title but can also be entered or altered manually, so that while the page title remains designed for display and human readability, its slug may be optimized for brevity or for consumption by search engines.
