Read over the post made by tess, since things have changed with the search engines in how they view the same article being submitted to lets say 10 article directories, that it can actually hurt more then help because of duplication..
So in order to be aggressive to help build some back links then should instead submit different articles to different directories every week whether it is 5 or 10 but always a different article to different directories wrong or right if wrong why if right why????
