Your question seems to be confusing to me. You've posted an article in ezine & you want to promote it. I think this is what you want to say. If I'm correct then you can post your article in twitter & facebook. Submit it other articles also where you'll get exposure. Also, you submit it to the social bookmarking sites like reddit, digg etc.
Ya.. Even I am confuse here.. Please elaborate your question further.. Do you want, How to submit article to Ezine or You want to know How to promote already submitted article?
if you summmit content ezine site then content quality base not grammer mistake then acppet your content on ezine site
same with any other link or site.. you can submit it to some social bookmarking and social networking sites..
You can promote your ezine articles by social bookmarking methods and blogging. There are also other article submission sites where you can post the contents you have. Hope this helps
Bookmark it on high PR site like Digg, Stumble upon, reddit, and then make some ads on it posting it to classified ad sites.
Share your article link in social networking site like Facebook, Twitter and bookmark your article that helps to promote your article.
Before even promoting the article you have submitted to ezine.com, review it first and check for some grammar mistakes. You won't get people reading your article if even on the first sentence they don't understand what you are trying to say. Once you are done with revising it with the correct grammar and all, share it in blog and social bookmarking sites.
