In most cases, you should add the site for the hostname under which you publish your articles. For example, if you publish your articles at URLs such as http://www.example.com/business/article123.html, you should add the site http://www.example.com/. Exception: If your site is within a hosting site, you should add the site for your homepage, e.g., http://members.tripod.com/mynewssite/. If you publish articles under multiple hostnames, you should add a site for each of them.
