Over the years we have amassed a few hundred articles on Ezine articles. Most of these were written by me and a few were subbed out. As of late, we do very little article submissions. In fact the only article submissions we do are the ones we don't care to publish on our blogs.
However, I was looking through our past articles on Ezine today and found that most of these articles are "grey-barred" and receive little or no traffic. This got me thinking ... what if I had one of my third-world link builders start attacking these articles to try and increase the link juice?
I know the article factories have had their link juice severely "nerfed" post panda, but, for a couple hundred bucks I could beef up all of these articles and change the link text to more relevant and current keywords.
Should I or Shouldn't I?
