Article submission is an extremely powerful process and too be honest I am not sure wether i agree with doing it automatically. My current SEO stratergys for article marketing are fairly simple. I outsouce an article to be written by a professional english writer, the article must contain at least 1,200 words and be of extremely high quality. Next i will submit it to the top 20 article websites based on Page Rank and traffic. After submitting the articles i will then do some basic backlinking and bookmarking to make sure they get indexed by the search engine spiders. I find that doing article marketing this way works extremely effective however i suppose that having the software submit less quality articles to the less dominant websites and then submit to the ones manually that you can't use a tool for with your quality article because at the end of the day quality backlinks never hurt anyone.
