URL Parameter
URL Parameters are elements that are added onto the base URL that can be used to serve a specific variation of a landing page or track traffic from a specific source that has been provided with the URL parameters. A question mark at the end of the base URL indicates that the following elements are parameters and not part of the base URL. The following is an example of a URL with a parameter: http://example.com/posts/todays-post?source=facebook.
