The biggest question I have for you is, how do you promote your article? I'm also finding ways on how to promote my article to generate tons of traffic but I cannot say that I am 100% successful all the time.
It works but at a very small scale. Since, these links are easy to acquire Google has started to give them less authority, but however I believe they contain a little amount of authority for sure. So, building them won't be a bad choice.
It is important that you share your content with others. Article submission effects little bit level. And it helps to get traffic if your article have real information that not only promote your site but also helpful to other. Article submission is good thing to get traffic.
