What is considered as a duplicate content in Article Marketing and it effects on SEO

What is considered as a duplicate content in Article Marketing and how it effects the rank of website?????

Hi
I have a website which currently has a unique content on it.

Now in order to get more backlinks to the website i am considering using Article Marketing and Press releases.
My question is what will be considered as a duplicate content in article marketing??????

I have 3 following scenarios. Which one will be the best and worst for SEO and generating high quality backlinks and ranking high on search engines.

1) The Unique article which i have on the website is copied and posted on several article directories with backlinks to my website
2) Unique Article Number 1 on my website. Now i wrote a new unique article no 2 and posted on one article directory and later on the same article no 2 is posted on all other article directories.
3) Unique article 1 on my website. Unique article no 2 on article directory no: 1. Unique article no 3 is now posted on a article directory: 2 and so on ......this means new article on every new article directory besides having unique content on the webiste.

Your comments will be appreciated.
thanks

 

Always try to make articles as unique as possible. You can use any free article spinning software..

 

Each time you want to post an article someplace with a backlink to your site you need an original article. Otherwise you can post the same article in 1000 places and see no result.
