It,s a good news for bloggers !
Todays, you don't need to wait for the GoogleBot to crawl your blog. Just click Google blog search and Google will directly indexed your new post.
Hmm, What is the Google Blog Search Pinging Service?
The Google Blog Search Pinging Service is a way to inform Google Blog Search of weblog updates. These updates are then published and shared with other search engines to allow them to discover the changes to your weblogs. In addition, Google Blog Search will add submitted weblogs to the list of blogs it needs to crawl and index.
If your blog has recently changed and you would like Google to crawl it please submit your blog URL here. Since this service is a one time notification service, every time your blog changes please submit your blog again.
