The time in which the current page will be displayed is the number immediately following content=". This is the number of seconds in which the page will be displayed. This number should be small, between 3 and 5 seconds. A wait of more than 5 seconds will cause user annoyance.
Following the url= is the page in which you want the user to be redirected to. This URL must be an absolute URL. This means that you must include the http:// followed by the domain name, and ultimately the path to the page you are redirecting the user to. It is also important to note that url is not a separate attribute but a substring that is a part of the content attribute.
