Simply put, a ping is a “this site has new content” notification that invites search engine bots to visit your blog.

By default, WordPress pings one pinging service called Ping-o-matic; that service will in turn ping others.

You can always add additional pinging services to be notified when new content is published. Simply go to Settings > Writing in the admin panel.
