Ping

As blogs have come into widespread use across the Internet, blog referral and tracking services have come into being. Companies like Technorati, Postami, BlogPulse and Google follow blogs and keep track of what's important in the blogosphere — which bloggers are commanding attention, what ideas are rising in prominence, and the speed at which these conversations are taking place.

Blog - Setup: Ping Tab

You can configure your blog to ping these blog directory services every time your blog page is updated. To add a service to ping, click the (+) button, type the name of the service and the URL to its "ping" page (the page on the service that accepts pings) and click the "Ping the following blog directories" box. You can also send a ping immediately to any newly-added service by selecting its entry in the list and clicking the "Ping Now" button.
