Google Blog Search Pinger

You can now ping Google when your blog changed for faster inclusion in Google Blog search. You can also allow you Blogware or blogging platform to take care of pinging using XML-PRC.

If your using Live Writer, then add http://blogsearch.google.com/ping/RPC2 under Tools >> Preferences >> Ping Servers.

OR

If your using Wordpress to run your blog, then login to your Wordpress Admin Panel and add http://blogsearch.google.com/ping/RPC2 under Options >> Writing.

Please use any one of the above technique, because if you ping multiple times, there are chances that Google might block your forever, So better be safe than sorry.
