It's best to use a content generator since it could make a something like original articles (but not of high quality). If you just copy paste content, you'll be penalized.
I have been using Dr Essay they are pretty good.
This is the first time I am hearing about "Dr Essay", will it generate high quality articles.
I have a .wordpress.com full of copy paste articles ranking on 3.0 according to google webmaster for a keyword. How do u explain that?
