Let me give you some tips for sccessful blog marketing for excellent SEO results.
1. Create a blog with Your prime keyword ( you can create as many blogs as you wish with all your prime keywords)
2. Put a good content on each post, make sure each post has title with your keyword and content should have keyword as well.
3. If you can write content, that is good, if you cannot, you can copy content from other blog, modify it such a way that it looks original
4. Put links to your site within the blog content ( 2-3 maximum)
5. Keep your blog updated, i am advising put 2 posts a week in each blog ( you might have more blogs, keep them updated weekly).
6. Now submit all of those blogs to blog directories so blog gets promoted and ranked ( http://www.searchenginejournal.com/2…-blog-to/5998/ )
7. Now an interesting step, you have to create a secondary blog to promote your primary blog. Like if you have primary on blogger.com, create a new secondary blog on wordpress.com.
8. On secondary blog, do same thing above but here you put links to your primary blog ( not your website link). so your primary blog gets one way links and it gets pr.
9. Digg your both kind of blogs daily
if you follow above nine steps, you will have good one way links permanently from your own sources and they are never going to be removed without your permission.
