Need to clarify on Article Marketing which helps in link building for SEO

[aman85]

Hi
I need to clarify on Article Marketing for SEO and link building.

A lot of people say that duplicate articles are not of much help to SEO. Now the confusion i have is what is considered as duplicate. To explain more about the confusion, please see the following 2 examples-

1) Do they mean duplicate articles on one website
Example: I wrote one unique article and posted it on Ezine Article today. After some days the same article was posted on Ezine Aritlcle again.


OR

2) Duplicate articles on all websites.
Example: I wrote one unique article and posted it on Ezine Articles. Then the same article was posted on Article-Base, Buzzle,Go articles Etc etc


Now which one of the above OR both will be considered as duplicate article marketing strategy.

Your comments will be appreciated.
Thanks
