There are many things you can do the article submission, blog comments and social bookmarks, which are sure to get targeted traffic as efficiently as those mentioned above. The possibilities are endless to keep learning and discovering.

I will also suggest you that , you should update your site or blog with good targeted content daily or on weekly basis. Use social networking sites , publish videos on youtube, add coments, I hope this will help to get traffic. Do not get involved in fake or viral traffic networks or any type of program.
