With each article that gets accepted to EzineArticles you can
1. Get the Rss Feed for that article. Submit that to a bunch of RSS directories
2. Put your article URL into places like Squidoo, Weebly, Hubpages, Blogger. Use anchor text when doing this.
Thats just 2 things off the top of my head. There are many other things that you can do with your articles. Like everyone else said, its good to keep writing articles daily or outsource, because you never know which article will be your money maker. Plus you get the most traffic from your articles when they are first published, because they get indexed temporarily, and they are on the first page of Ezinearticles.
Also, when creating your articles make sure that you put 2 anchor texts in the description box in your articles with your webpage in the anchor. Make it look like part of the article.
I no longer do article marketing, but is is effective. Pm me if you would like a link to my Ezinearticles author page. I was going to post it in the thread but I dont think thats a good idea because my entire name is there and I may have one of my email addresses in there.
You can look at some of the articles for reference. It may also give you some niche ideas. I still make sales today with articles that I have written almost a year ago.
