What is interesting is that articles that get a few earnings will not show as those that are generating traffic (traffic data can be seen at your StatCounter account) and vice-versa. That is why it is a bit frustrating when you see high traffic and no earnings!
What Umesh mentioned is known by some publishers, that one should not promote articles via FB or other social media platforms and this is considered to be inorganic traffic. However, if you have your own blog or website, you can give a relevant link within the text of a post there to an ISC article. Of course, like for anywhere where you submit content, you need to be careful not to place links near the ad units or images.
