What about considering few of your blog posts for articles at the end of each month. For example selecting some blog posts from previous month and re-write them in the form of articles that might be useful to a person seeking for that exact piece of information.
Top article directories are visited by millions of readers on daily basis and you can just image the kind of exposure you can get when your articles are listed on those directories. You can write and submit them to those directories manually or you can hire a person who will do it for you. I will not advise using any automatic article submission tool at the beginning because they do not guarantee submission .
I am listing few of the top article directories that get huge traffic (as reflected from their Alexa traffic rankings) :
Submit your articles to the above directories and also make sure that your articles are useful and unique otherwise you will not be able to get traffic in terms of both quality and quantity.
