If you want to get known quickly and in a huge way, post often.
  Your readers and Google want new content.
The way to make that happen is to post frequently.
In fact, if you post on a schedule - like Monday, Wednesday, and Friday, you will train your readers to come back to your blog on a schedule to see what's new.
Whenever you publish a new post you can have it go automatically to Twitter, Facebook, FriendFeed and any number of other social networks.
  Frequent posting puts you and your blog 'out there' for people to see.
  The whole point is to drive traffic back to your blog.
  But remember, frequent posting and getting yourself out there isn't enough.
  You must have great content to get people to come back.
You can also e-mail your community and tell them about reach new post..
  Ask them to read and comment.
  Start the conversation.
  Don't forget to include the URL to your post!  Each time you e-mail, remind your community of your schedule.
  Some people even schedule their posts to post at the same time each day there is a scheduled post.
As Google and the other search engines  find new content they will visit more and more often.
  The more they visit, the more opportunity you have for them to be impressed with your content.
  Always make it relevant to the topic of your blog.
  Each post should dig even deeper and stick to one subject - in other words be tightly focused.
