If you have one article and need submit it to some different article site,what will you do? If i just copy it ,i think is not well,but how can i mend it ?
Hire a writer if you can't write good articles yourself. As much as I would like to submit unique articles to each article directory, I submit each article to 50 directories and write another one for next submissions.
In my opinion if u want to submit the same article in different sites than u should change anchor tags and keywords or some more changes whatever u think u can...
