Ping services allow you to automatically notify blog directories and search engines that your blog has been updated. The bigger your ping list the higher the chances of receiving traffic from those sources, so check out the list below and include it on your blog (Wordpress users can modify their ping list on the Control Panel, then Options, then Writing).
