What are some of the best and easiest way to drive traffic to your blog?

I have two blogs
themoneyoppo.blogspot.com
hoobersoft.blogspot.com

I kinda just started them and the content... well to be honest, just normal. However, i dun think anyone even know these two sites exist. Probably just me. What are some of the best way that make them more noticeable without doing like sponsoring (pay $$ each month)? Hopefully for free.

I suggest you build backlinks on blog /niche/general link directories, related theme blogs, forums, social bookmarking and networking sites, etc. This will eventually increase your exposure on the net and also help in the SEO of your blog in the long run. Such backlinks are also potential sources of direct traffic overtime.
