First of all you need to make sure that you have chosen a direction with your blogs >
What niche do I want to market?
What keywords do I want to push?
The second step is to start trading. A good way to find your first trades is by using programs like

They won't do you miracles, but its a way to start.
Some more tips:
*Get
google analytics to monitore your traffic and wait till the SE bots pick you up.
*Keep writing blog posts and try to keep them original and focused on your keywords.
*Trade with blogs in your own niche.
*If you decide to list your blog in all kinds of toplists be sure to check if they really send any traffic.
