You should try to write at least one link inside your blog post back to your own blog, a site linking to your blog, or some other location which eventually can lead back to your site or a product associated with your site. Why should you put links in your blog posts? It's simple... websites that rip your content and paste it on their own sites will take credit for your work no matter what measures you take to prevent it. Therefore, why not allow these sites which steal your content to become billboards? Why not turn this around and use those sites to drive traffic to your own?
Sounds simple and easy, but it actually takes some thought as you don't want to annoy your regular readers with links to your home page, so try to spice things up by linking back to old articles or sites which in turn link to your own. You can also put the name of your site in there without using a link, and I highly encourage this so that people will google and find you. The reason you should do this is because many of the sites which steal your content and reproduce it word for word will take out your hyperlinks which destroys the whole point of putting links into the posts in the first place. Therefore it would be wise to put your blog's name inside the article for users to search for it.
