Ping-O-Matic is a service that allows you to communicate, to multiple blogs finder, the updating of your blog or web site.
There are various search engines for blogs that require a precise "signal" to update the blog, pinging exactly, like Technorati.
To Ping a web space to everyone of these finder is quite long, especially if the blog platform that we use don't do this automatically. Ping-O-Matic takes the burden for us!
The first time you use the service, you must include the address of your blog and select the search engines you want to ping. Ping-O-Matic will do the rest!
