Article marketing looks simple until you have written thirty pieces and none of them moved anything at all. Kyle Haycock spent most of a year on exactly that gap, and the posts read like someone working the problem rather than someone selling a course about it.
His recurring argument is that small details decide the outcome. What you give away, and why a freebie should carry your logo. Where a no-follow tag belongs and where it does not. Why regurgitated information fails even when it is technically accurate and neatly spaced. The advice is specific enough to act on the same afternoon you read it.
There is a second strand running through these posts about the physical business of writing at volume: how a desk is set up, what an unfinished stack of drafts does to your head, why ergonomics matter when the work is hours of typing.
If your articles are going out and nothing is coming back, start here rather than with another list of tactics from somebody else.
