sem4u is right set up some quality links to your blog and the spiders will follow to index your blog..
If you're running a blog you could submit your rss feed to Yahoo,

And put up an sitemap.xml suggest it to goole,
https://www.google.com/webmasters/si.../protocol.html
I did it with a new site, about 3 weeks old and the site is now completely indexed by google.
