Winningratings,
I really beg to differ,
Actually, duplicate content has nothing to do with same articles appearing on different sites.
Here is a great
5 Star Hall of Fame Thread from Jim that really defines what duplicate content is:
Duplicate Content: It’s Not What You Think!
Also, many high quality article sites have massive traffic, like Ezine and if you write interesting, enticing articles, you will most definitely get traffic and targeted traffic if you are using targeted KW in your anchors. Many successful Internet marketers use Article Marketing and I do as well, and it continues to be a highly effective, free and optimal marketing technique.
Article Marketing works great, even if you submit the SAME article to 15,000 sites (which you should) - this is NOT duplicate content
1. You will get one-way backlinks from the SE's which is optimizing for
SEO
2. You will get targeted traffic from the sites themselves, if you write good stuff and use the right KW's for conversions/sales in your anchor text.
