Create a blog and start making posts, after you have created at least five posts
now you are ready to start submitting your blog to the major blog directories. It is very important when you make posts in your blog that you always link back to your domain or sub domains within your posts, if you don't, your efforts will be done in vain and your incoming links won't count. If you are not an excellent writer or do not have the time to write content for your blog, then I recommend that you do post comments to at least ten "do follow blogs" daily.
