I am article marketing as with just a few articles i have seen a good amount of traffic. One thing i am not good with is writing and i have no money to outsource work. So what i am doing is re writing articles that are on the article directories and re submitting them. I am using word flood to help me do this and i just want to know how much of the article do i have to change for it to be seen as new content. At the moment i have been changing 20+% of the articles. Is this enough?
