Well Ezine Articles is the biggest article-directory there is, but people are having issues to get tons of traffic from it, and views to the article, since you are competing against many.
But I just got a thought in mind that I had 1 week ago, and many times before, but never thought clearly about it.
Doing bit of keyword research, writing an article for that keyword , so it is seo-optimized , and then publishing to Ezine...
Once approved, do a big Xrumer blast or backlink blast (SEO basically) for the keyword, and your article should rank way more easier than for your site (Since Ezine is big)..... and you'll get tons of views, and also visitors!
I will be trying this soon, but I wanna hear your thoughts
